1 About these Terms

These Terms & Conditions ("Terms") form a legally binding agreement between you ("you", "your", "User", "Contributor") and QADRION ("QADRION", "we", "us", "our"), the operator of the QADRION monument, website, applications, and related services (collectively, the "Platform"). By creating an account, claiming a fragment, making a payment, or otherwise accessing or using the Platform, you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference.

If you do not agree to these Terms, you must not use the Platform. If you use the Platform on behalf of an organisation, you represent that you have authority to bind that organisation to these Terms.

2 What QADRION is

QADRION is, simultaneously:

• a collaborative digital monument — a single, evolving canvas composed of contributions from people around the world;
• a permanent public archive — a historical record of contributions, coordinates, inscriptions, and certificates;
• a digital artwork — a cultural and creative work; and
• a historical record system — a verifiable ledger of who contributed, where, and when.

QADRION is a cultural and artistic project. It is not a bank, broker-dealer, exchange, money transmitter, securities issuer, or investment platform, and it does not offer financial, investment, tax, or legal advice.

3 Eligibility & age requirements

You must be at least 18 years old, or the legal age of majority in your jurisdiction (if higher), and capable of forming a binding contract, to create an account, purchase fragments, or use any payment feature. You must not use the Platform if you are barred from doing so under any applicable law, or if you are located in, or are a resident of, any jurisdiction subject to comprehensive sanctions. QADRION may request age verification and may suspend or terminate accounts that fail to meet age-verification requirements. You are responsible for complying with all laws that apply to you.

4 Accounts & security

You are responsible for safeguarding your account credentials and for all activity that occurs under your account. You agree to provide accurate information, to keep it current, and to notify us promptly of any unauthorised use. We may refuse, suspend, or reclaim any username, and may require identity or payment verification to protect the Platform and its users.

5 Fragment ownership

When your contribution is confirmed, you acquire ownership of the specific digital fragments you purchased and the associated archive records (including their coordinates, artwork, title, inscription, and certificate), subject to these Terms.

Purchasing fragments does NOT grant you any of the following:

• ownership of QADRION, the Platform, the monument as a whole, or its underlying software, brand, or infrastructure;
• any equity, shares, securities, tokens, or other financial instrument;
• any voting, governance, management, or control rights;
• any right to profit, revenue, dividends, distributions, or proceeds; or
• any investment, lending, or ownership interest in QADRION or any affiliated entity.

Your rights are limited to the recorded digital fragments within the monument and the archive records associated with them.

6 Not an investment

QADRION contributions are not investments and must never be purchased with any expectation of profit, appreciation, resale value, yield, or financial return. Fragments are cultural and commemorative digital items. QADRION makes no representation or guarantee regarding resale value, liquidity, market, or future worth. You acknowledge that you may receive no financial benefit of any kind and that the entire amount you pay may be treated as a contribution to a digital artwork and archive.

Digital-asset nature. A fragment represents a digital ownership record within the monument only. Fragments are not securities, shares, investment contracts, cryptocurrencies, virtual currencies, tokens, financial instruments, derivatives, real property, or an ownership interest in QADRION or any entity, and they confer no profit, dividend, revenue, equity, voting, or governance rights.

7 Payments, pricing & Stripe

Payments are processed by Stripe and/or other certified third-party payment providers. By making a payment, you also agree to the applicable payment provider's terms. QADRION never receives or stores your full card number, CVC, or other sensitive payment credentials; these are handled directly by the payment provider under its own PCI-DSS-compliant systems. We receive limited payment metadata (such as a confirmation, partial card information, country, and a transaction reference) to operate the Platform, prevent fraud, and meet legal obligations.

Prices, applicable processing fees, and totals are displayed before you confirm. All amounts are payable in the currency shown. You are responsible for any taxes that apply to your purchase unless stated otherwise.

8 Refund policy

Because each fragment is a unique digital item inscribed into a permanent archive at the moment of purchase, QADRION contributions are FINAL. In particular, there are no refunds:

• after a fragment has been successfully recorded;
• after a certificate has been issued;
• for completed contributions;
• for a change of mind;
• for unmet future-value expectations;
• for monument growth, ownership percentages, rankings, or archive evolution.

Exceptions. Refunds may only apply where required by applicable law, or in cases of a verified duplicate charge or a confirmed technical payment failure that prevented your fragment from being recorded. To request a refund under these exceptions, contact connect@qadrion.com (or contact@qadrion.com) with your transaction reference. Nothing in this policy limits non-waivable statutory rights you may have under the law that applies to you.

9 Chargebacks & payment abuse

If you believe a charge is incorrect, contact us before initiating a chargeback so we can resolve it. Initiating a fraudulent or bad-faith chargeback, abusing the payment system, or disputing a payment after your contribution has been successfully delivered and recorded is a material breach of these Terms. We may, in response and to the extent legally permitted: suspend or terminate your account; conduct an ownership review; reverse, revoke, or invalidate affected fragments and certificates; pursue recovery actions for amounts owed (including fees and costs); report fraud to payment providers and authorities; and impose permanent platform restrictions on accounts and persons associated with chargeback or payment abuse.

10 User-generated content & your responsibility

You are solely responsible for everything you contribute, including artwork, images, colours, fragment titles, inscriptions, legacy messages, and your username ("User Content"). You represent and warrant that you own or have all necessary rights to your User Content and that it does not infringe any third-party rights or violate any law. Fragment titles, inscriptions, usernames, country flags, coordinates, and artwork are public and may be viewed, indexed, and shared by anyone who discovers your fragment.

11 Copyright, ownership & content licence

You retain ownership of the original content you create and submit (your User Content). You grant QADRION a worldwide, non-exclusive, royalty-free, sublicensable, perpetual, and irrevocable licence to host, store, preserve, archive, reproduce, display, adapt for technical purposes, and publicly present your User Content as part of the monument, the archive, certificates, previews, and related historical and promotional materials. This licence exists so that the monument and its public record can operate and persist, and it survives deletion of your account to the extent necessary to preserve the historical archive.

Future presentations of the monument. If QADRION later offers prints, books, exhibitions, galleries, museum presentations, digital showcases, merchandise, collector editions, licensed collections, a boutique, or a marketplace, QADRION may display and reproduce contributed fragments as part of collective presentations of the monument as a whole, while respecting the underlying ownership records of individual fragments. Such activities relate to the monument as a unified collective artwork and do not alter or transfer the underlying ownership records. Such collective presentations relate to the monument as a unified work; they do not transfer your copyright in your individual User Content to QADRION, and they remain subject to applicable law.

12 Prohibited content & conduct

You must not upload, inscribe, or transmit content that: is illegal, infringing, or fraudulent; contains hate speech, harassment, threats, or violent extremist symbols; is sexually explicit or exploits minors; impersonates others or is deceptive; contains malware or attempts to compromise the Platform; or violates the privacy or intellectual-property rights of others. You must not interfere with, scrape, overload, reverse-engineer, or circumvent the Platform's security or access controls.

13 Content moderation rights

To protect users, comply with law, and preserve the integrity of the monument, QADRION may at any time and at its discretion remove, hide, reject, restrict, or block any content or account for legal, safety, fraud, copyright, security, or policy reasons. We are not obligated to monitor content, but we may do so. Moderation actions do not entitle you to a refund where your conduct or content caused the action.

14 Copyright & DMCA

QADRION respects intellectual-property rights and responds to valid notices of claimed infringement, including under the U.S. Digital Millennium Copyright Act (DMCA) and comparable laws. If you believe content on the Platform infringes your copyright, send a notice to connect@qadrion.com (or contact@qadrion.com) including: identification of the work; the location of the allegedly infringing material; your contact details; a good-faith statement; a statement under penalty of perjury that the information is accurate and that you are authorised to act; and your signature. We may remove allegedly infringing material and may terminate repeat infringers.

15 Certificates

Certificates are commemorative records that confirm a contribution and its archive details (such as a serial, fragment number, and date). A certificate is proof of recorded ownership within the QADRION monument only. It is not a government-issued document, a financial certificate, a security, a legal title or deed, or an investment instrument, and it confers no rights beyond those described in these Terms. We may reissue, correct, or revoke certificates associated with reversed, fraudulent, or unlawful transactions.

16 Permanent public archive

Important. QADRION is designed as a permanent historical record. By contributing, you understand and agree that your contribution records, certificates, ownership history, contribution timestamps, coordinates, ranking and archive references, and related archive data may become a permanent part of the public historical archive. Such records may remain publicly visible and preserved even if you later delete your account.

Historical integrity. You may request account deletion at any time; however, to preserve the integrity and authenticity of the monument, QADRION may retain the monument records, ownership history, contribution timestamps, coordinates, certificates, and archive data necessary for that purpose. Where the law grants you deletion or de-identification rights, we will honour them as required, but the permanence of certain archive records is a core, disclosed feature of the Platform and may lawfully be retained for historical, archival, security, and legal-compliance purposes.

17 Suspension & termination

QADRION reserves the right to suspend, restrict, investigate, or permanently terminate accounts and access, remove content, and revoke or invalidate affected fragments or certificates, with or without notice and to the extent permitted by law, for any of the following:

• fraud or fraudulent activity;
• payment abuse;
• chargeback abuse;
• sanctions or export-control violations;
• platform manipulation or gaming of rankings, pricing, or systems;
• illegal activity;
• security threats or attempts to compromise the Platform;
• violation of these Terms or our policies.

You may stop using the Platform at any time. Provisions that by their nature should survive termination (including ownership records, licences necessary for the archive, disclaimers, limitations of liability, indemnities, and dispute terms) will survive.

18 Platform availability disclaimer

The Platform is provided on an "AS IS" and "AS AVAILABLE" basis. We do not guarantee:

• uninterrupted operation;
• continuous availability;
• the absence of bugs or errors;
• the absence of outages or downtime;
• permanent access to all features.

Temporary interruptions may occur, and we may modify, suspend, or discontinue any part of the Platform at any time. We will use commercially reasonable efforts to preserve legitimate ownership and archive records.

19 Future platform evolution

QADRION may evolve, expand, redesign, rebrand, add features, remove features, and modify the monument's functionality, presentation, and surrounding experiences over time, in its sole discretion, while preserving legitimate ownership records and the integrity of the archive. Changes to design or features do not entitle you to a refund and do not diminish your recorded ownership of your fragments.

20 Intellectual property

The Platform, including the QADRION name, logos, software, design, and the compilation and arrangement of the monument, is owned by QADRION or its licensors and is protected by intellectual-property laws. Except for the limited rights expressly granted to you in these Terms, no rights are transferred to you. You may not copy, modify, distribute, or create derivative works of the Platform except as permitted by law.

21 Disclaimers

To the maximum extent permitted by law, QADRION disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, title, and non-infringement. We make no warranty regarding value, performance, availability, or the conduct of any user. Some jurisdictions do not allow certain disclaimers, so some of the above may not apply to you.

22 Limitation of liability

To the maximum extent permitted by law, QADRION and its officers, employees, and agents will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost data, loss of goodwill, or loss of value, arising out of or relating to the Platform or these Terms, even if advised of the possibility. To the maximum extent permitted by law, our total aggregate liability relating to any claim shall not exceed the amount you paid for the specific contribution giving rise to the claim; and in no event will our total aggregate liability for all claims relating to the Platform exceed the greater of (a) the total amount you paid to QADRION in the twelve (12) months before the event giving rise to the claim, or (b) USD 100. Nothing in these Terms excludes liability that cannot be excluded by law.

23 Indemnification

You agree to indemnify, defend, and hold harmless QADRION and its affiliates from any claims, damages, liabilities, costs, and expenses (including reasonable legal fees) arising from your User Content, your use of the Platform, your violation of these Terms, or your violation of any law or third-party right.

24 Force majeure

QADRION shall not be liable for any delay, interruption, failure, or loss caused by events beyond its reasonable control, including:

• natural disasters, acts of God, and pandemics;
• war, terrorism, and civil unrest;
• cyber-attacks and security incidents;
• infrastructure, hosting, payment, or third-party service failures;
• internet or telecommunications outages;
• government actions, sanctions, or legal restrictions;
• labour disputes; and
• any other events beyond our reasonable control.

25 Dispute resolution & arbitration

Most concerns can be resolved by contacting us first at connect@qadrion.com (or contact@qadrion.com), and you agree to attempt good-faith informal resolution before commencing formal proceedings. To the extent permitted by applicable law, you and QADRION agree that disputes that are not resolved informally will be resolved by final and binding individual arbitration, rather than in court, and that you and QADRION each waive any right to a jury trial and to participate in a class action or class-wide arbitration. The arbitration will be conducted by a recognised arbitration body under its applicable rules. Mandatory consumer-protection laws may give you additional rights, and nothing here removes rights that cannot be waived under the law that applies to you (for example, certain EU/UK consumers may bring claims in their local courts).

26 Governing law & jurisdiction

These Terms, and all legal disputes, claims, and interpretations arising out of or relating to them or to your use of the Platform, shall be governed by and construed in accordance with the applicable laws of the United States of America and the specific governing jurisdiction designated by QADRION [GOVERNING_STATE], without regard to conflict-of-law principles. The competent state and federal courts and/or the arbitration seat located in that designated jurisdiction shall have jurisdiction, subject to Section 25 (Dispute Resolution & Arbitration).

The specific U.S. state (for example, Delaware or Wyoming) is configurable via [GOVERNING_STATE] and will be designated by QADRION; this architecture allows the governing state to be finalised with legal counsel. The foregoing applies except that mandatory consumer-protection laws of your country of residence continue to apply where required by law.

27 International users

QADRION is accessible internationally. You are responsible for compliance with local laws, including export, sanctions, tax, and content laws. By using the Platform from outside the operator's home jurisdiction, you consent to the processing and storage of information as described in the Privacy Policy, including cross-border transfers subject to appropriate safeguards.

28 Founder rankings & statistics

Founder rankings, collector positions, ownership percentages, contribution statistics, rarity indicators, and archive metrics are provided for informational and commemorative purposes only. They are estimates that may change as the monument evolves, as contributions are added, removed, or corrected, and as methodologies are updated. They are not guarantees, valuations, or representations of value, status, or entitlement, and you should not rely on them for any financial, investment, or legal purpose.

29 AI-generated artwork

The AI Pixel Assistant and any AI features — including AI-generated designs, suggestions, artwork, layouts, and recommendations — are provided for creative assistance only. QADRION makes no representation or warranty and provides no guarantee regarding the uniqueness, originality, copyright eligibility, trademark availability, non-infringement, freedom from third-party claims, or commercial usability of any AI-generated output. You remain solely responsible for your final selections and for ensuring that your contribution does not infringe the rights of others or violate any law. AI-generated designs may resemble other works, and similar or identical outputs may be generated for other users.

30 Transfer & resale restriction

Unless and until expressly enabled by QADRION in the future, fragment ownership does not include any resale, transfer, assignment, marketplace, secondary-trading, or commercial-trading rights. Fragments and certificates are personal, non-transferable archive records. Any future transfer or resale functionality, if introduced, will be subject to additional terms, eligibility, and conditions determined by QADRION. Purported transfers made outside any mechanism we provide are void and not recognised in the archive.

31 Platform continuity

If QADRION is acquired, merged, reorganised, restructured, sold, or discontinued, we will use commercially reasonable efforts to preserve monument records, ownership history, certificates, and archive data, and to transition them to a successor or archival custodian where practicable. Nothing in this clause guarantees indefinite operation of the live Platform; it reflects our intention to preserve legitimate ownership and historical records to the extent reasonably possible.

32 Sanctions & restricted territories

You may not access or use QADRION in violation of any export-control laws, sanctions regulations, trade restrictions, or embargo requirements. QADRION reserves the right to restrict, suspend, or terminate access, payments, or contributions for any user who is located in, ordinarily resident in, or acting on behalf of any country, region, or person subject to comprehensive economic sanctions or trade restrictions, or who is otherwise prohibited under applicable export-control, anti-money-laundering, counter-terrorism, or sanctions laws and regulations, and to restrict access wherever required by law. You represent that you are not subject to such restrictions and that your use of the Platform is lawful in your jurisdiction.

33 Monument vision & legacy

QADRION is intended to become a long-term global digital monument and historical archive. You acknowledge and agree that the monument may continue to evolve, expand, and operate over many years — potentially for decades — and that future generations and members of the public may access preserved archive records and public contributions. By contributing, you participate in a work intended to endure as a lasting public record, and you accept the long-term, public, and historical nature of that participation.

34 Authoritative ownership records

In the event of any discrepancy, conflict, technical issue, error, screenshot, export, cached page, printout, or third-party record, QADRION's internal ownership records and database records shall be the authoritative and controlling source of truth regarding the existence, ownership, coordinates, history, and details of any fragment or certificate. No external copy, cache, screenshot, or representation overrides QADRION's records. We may correct records to address fraud, error, reversed payments, or technical faults.

35 Successors & assigns

These Terms, and your contributions and ownership records under them, remain binding upon and inure to the benefit of you and QADRION and our respective successors, assigns, acquirers, merged or reorganised entities, and future operators of QADRION. You may not assign or transfer your rights or obligations under these Terms except as expressly permitted by us. We may assign these Terms in connection with a merger, acquisition, reorganisation, financing, or sale of assets.

36 Fraud prevention, AML & compliance

To protect users and meet our legal and payment-provider obligations, QADRION may, at any time and to the extent permitted by law: request identity or age verification; delay, hold, or decline transactions; review or freeze ownership records; suspend contributions; and restrict, block, or terminate accounts. We take these measures to comply with anti-fraud requirements, sanctions and export-control laws, anti-money-laundering (AML) and counter-terrorist-financing obligations, "know-your-customer" expectations, and the requirements of our payment providers (including Stripe). You agree to provide accurate information and reasonable cooperation in any such review.

37 No financial, legal, or tax advice

Nothing on QADRION — including the Platform, the monument, fragments, certificates, rankings, statistics, or any communication from us — constitutes investment advice, financial advice, legal advice, tax advice, or accounting advice, and nothing should be relied upon as such. QADRION is a cultural and artistic project, not a financial adviser or fiduciary. You should obtain independent professional advice where appropriate before making any decision.

38 Taxes

You are solely responsible for determining, reporting, and paying any and all taxes, duties, or levies (including VAT, GST, sales, income, or similar taxes) that may arise from your use of QADRION, your purchases, your ownership records, or any other Platform activity. Unless we state that a price is tax-inclusive, taxes are your responsibility. QADRION does not provide tax advice and is not responsible for your tax obligations.

39 Inheritance & succession

QADRION may, in the future, introduce inheritance, beneficiary, legacy-transfer, or succession mechanisms for fragments and archive records. Until and unless such systems exist, fragment ownership remains associated with the recorded account holder. QADRION is not responsible for estate administration, probate matters, inheritance disputes, or beneficiary claims, and is under no obligation to transfer, divide, or release fragments or certificates to heirs, estates, or third parties, except where explicitly supported through future platform features or required by a valid, applicable legal order.

40 Username & identity disclaimer

Ownership or use of a username on QADRION does not grant any trademark, copyright, publicity, celebrity, or identity rights, and does not represent endorsement by or association with any person or brand. QADRION reserves the right to modify, reclaim, suspend, or transfer usernames where necessary to comply with legal obligations, resolve disputes, prevent impersonation or deception, or protect legitimate rights holders. You must not select or use a username that infringes the rights of others or is misleading.

41 Monument evolution

QADRION may evolve over time. Future additions may include, without limitation: galleries, maps, archive layers, search systems, exhibitions, ownership visualisations, rankings, historical timelines, certificate systems, and new monument sections. Such changes, additions, removals, or redesigns do not invalidate legitimate ownership records, and we will use commercially reasonable efforts to preserve those records as the monument grows.

42 Data preservation disclaimer

QADRION is designed for long-term preservation. However, no digital system can guarantee absolute permanence. While we will make reasonable efforts to preserve monument records, ownership history, certificates, and archive data, QADRION cannot guarantee uninterrupted or perpetual preservation in all circumstances, including events beyond our reasonable control (see Section 24). This clause does not diminish your recorded ownership; it describes the inherent technical limits of any digital archive.

43 Certificate verification authority

Only verification pages hosted on official QADRION domains constitute authoritative proof of a certificate's validity. Screenshots, PDFs, printed copies, exports, and third-party reproductions are secondary representations and are not authoritative. In any dispute regarding the existence, validity, or details of a certificate or fragment, QADRION's verification records and database shall prevail (consistent with Section 34, Authoritative ownership records).

44 Beta & experimental features

Certain features may be offered as experimental, beta, preview, or early-access. Such features are provided "as is," may contain errors, and may be modified, suspended, redesigned, or removed at any time without notice. We make no warranty regarding experimental features and are not liable for any loss arising from their use.

45 Content standards & moderation

QADRION is a permanent monument and public archive. Because contributions may be preserved and publicly visible for the long term, not all content is allowed. This section supplements Sections 12 (Prohibited content) and 13 (Moderation rights).

45.1 Prohibited content. You must not submit, inscribe, upload, or link to:

• hate speech;
• terrorist content, extremist propaganda, or promotion of crime;
• child sexual exploitation material (zero tolerance);
• non-consensual sexual content or explicit pornography;
• threats of violence, harassment, or doxxing;
• private personal information of others;
• malware, malicious links, or fraudulent content;
• copyright or trademark infringement;
• impersonation; or
• spam.

45.2 Offensive language & context. Because QADRION is a historical archive, the presence of strong or "bad" words alone does not automatically result in removal — context matters. Generally allowed: artistic expression, emotional expression, historical quotations, personal messages, and cultural language. Potentially restricted: targeted harassment, hate speech, direct threats, and abusive attacks against individuals.

45.3 Monument integrity review. QADRION reserves the right to reject, hide, blur, limit the visibility of, or remove content where necessary for legal compliance, safety, fraud prevention, or monument integrity.

45.4 Permanent-record warning. Although QADRION is a long-term archive, not every submitted fragment is guaranteed permanent publication. Content that violates these standards may be removed, archived privately, restricted, or hidden.

45.5 Automated & AI moderation. QADRION may use automated systems and AI tools to help detect spam, scams, abuse, illegal content, and policy violations. Automated decisions may be reviewed by a human where appropriate or required by law.

45.6 Appeals. If you believe a moderation decision was made in error, you may request review by contacting connect@qadrion.com (or contact@qadrion.com).

45.7 Historical, educational & artistic exception. Historical, educational, journalistic, artistic, documentary, or research content may be treated differently from abusive content, and moderation decisions will consider context.

45.8 Final authority. QADRION retains final discretion regarding the publication of monument content, while attempting to preserve legitimate artistic and historical contributions wherever reasonably possible.

45.9 Review queue & ownership protection. To avoid penalising legitimate contributors for moderation uncertainty, a contribution flagged for review may still be paid for and recorded, with the fragment placed in a pending-review status: your payment, coordinates, ownership record, and fragment reservation remain valid and reserved for you, but the fragment, its certificate, and its verification page are withheld from public visibility until approved. Only approved content becomes publicly searchable and visible on certificates, verification pages, and archive displays. If content is questionable but fixable, we may mark it requires-edit and invite you to edit your title, inscription, image, or AI prompt without losing ownership. Payment is blocked only for extremely clear and severe violations, in which case you will be asked to modify your content before proceeding.

46 Changes to these Terms

We may update these Terms from time to time. Material changes will be indicated by updating the "Last updated" date and, where appropriate, by additional notice. Your continued use of the Platform after changes take effect constitutes acceptance of the updated Terms.

47 Contact

Questions about these Terms can be sent to connect@qadrion.com (primary) or contact@qadrion.com (secondary). The same addresses may be used for refund requests under Section 8, copyright and DMCA notices under Section 14, and dispute procedures under Section 25.

1 Introduction & scope

This Privacy Policy explains how QADRION ("we", "us", "our") collects, uses, discloses, and safeguards information when you use the Platform. It applies to all users worldwide. For data-protection purposes, QADRION acts as the "controller" of personal data processed through the Platform, except where a third party (such as a payment provider) acts as an independent controller of its own processing.

2 Information we collect

We collect the following categories of information:

• Account information — your username, display name, full name (if provided), and account settings.
• Email address — used to create your account, deliver certificates, send security and reset emails, and contact you.
• Country — your selected country/flag.
• Payment metadata — a confirmation, transaction reference, partial card information, billing country, and status received from our payment provider (never your full card number or CVC).
• IP address and approximate location derived from it.
• Browser & device information — device type, operating system, browser, language, and similar technical data.
• Activity logs — actions you take on the Platform, timestamps, and diagnostic logs.
• Contribution records — your selected fragments, coordinates, colours, and purchase history.
• Uploaded artwork, fragment titles, and inscriptions / legacy messages.
• Certificates — the records and identifiers generated for your contributions.

3 How we use your information

• Platform operation — to create accounts, display the monument, record contributions, and provide support.
• Fraud prevention — to detect, investigate, and prevent fraudulent, abusive, or unauthorised activity, including chargeback abuse.
• Legal compliance — to comply with laws, regulations, tax, sanctions, and lawful requests.
• Analytics — to understand and improve how the Platform is used.
• Security monitoring — to protect the Platform, accounts, and users.
• Certificate generation — to issue and verify certificates and archive records.
• Archive preservation — to maintain the permanent public historical record of the monument.

4 Public vs private data

QADRION is a public archive, so some information is intentionally public. Please read this carefully before contributing.

Public information may be viewed, indexed by search engines, copied, and shared by anyone. Do not place sensitive personal information in public fields such as titles or inscriptions.

5 Payments & Stripe

Payments are processed by Stripe and/or other certified third-party payment providers. QADRION does not receive or store your full card number, CVC, or sensitive payment credentials — these are collected and processed directly by the payment provider under its PCI-DSS-compliant systems and its own privacy policy. We receive only limited payment metadata necessary to confirm your contribution, prevent fraud, and meet legal obligations.

6 Cookies & similar technologies

QADRION does not currently use advertising cookies, cross-site tracking cookies, behavioural-targeting cookies, or third-party marketing cookies. We do not sell or share your data for advertising.

We use only technically necessary cookies and browser local storage to operate the Platform, specifically for:

• Authentication — to keep you securely signed in to your account;
• Security — to protect against fraud and abuse and to keep sessions safe;
• Sessions & preferences — to remember your cart, in-progress contribution, and basic settings so the Platform works.

These technologies are essential to the Platform; disabling them in your browser may prevent core features (such as signing in or completing a contribution) from working. If we introduce any non-essential cookies in the future, we will update this Policy and provide appropriate controls and consent.

7 Sharing & service providers

We share information only as needed to operate the Platform: with payment providers (e.g., Stripe), hosting and database providers, email-delivery providers, analytics providers, and security vendors, each acting as our processor under appropriate agreements; with authorities or parties where required by law or to protect rights, safety, and the integrity of the Platform; and in connection with a merger, acquisition, or asset transfer. We do not sell your personal information for money.

8 International data transfers

QADRION operates globally, and your information may be processed in countries other than your own, including countries that may not provide the same level of data protection. Where required, we rely on appropriate safeguards (such as Standard Contractual Clauses or equivalent mechanisms) for cross-border transfers.

9 Legal bases (GDPR / UK GDPR)

Where the EU or UK GDPR applies, we process personal data on these bases: performance of a contract (to provide the Platform and your fragments); legitimate interests (security, fraud prevention, analytics, and archive operation, balanced against your rights); legal obligation (compliance, tax, accounting); and consent (where required, e.g., certain cookies or communications), which you may withdraw at any time.

10 Your rights

Subject to applicable law, you may have the right to access, correct, delete, restrict, or object to processing of your personal data, to data portability, and to withdraw consent. EU/UK users may lodge a complaint with their supervisory authority. To exercise your rights, contact connect@qadrion.com (or contact@qadrion.com). We will respond within the timeframes required by law. Please note the permanent-archive disclosure below, which may limit deletion of certain public historical records where preservation is lawful and necessary.

11 California privacy rights (CCPA/CPRA)

If you are a California resident, you have the right to know what personal information we collect and how we use and disclose it, to request deletion, to correct inaccurate information, and to opt out of any "sale" or "sharing" of personal information as those terms are defined under California law. We do not sell your personal information for money. You will not be discriminated against for exercising your rights. To exercise these rights, contact connect@qadrion.com.

12 Permanent archive disclosure

Important. QADRION is a permanent public archive. Certain contribution records — including your username at the time of contribution, fragment coordinates, artwork, title, inscription, certificate, ownership history, contribution timestamps, ranking and archive references, and archive entries — are designed to be a permanent historical record and may remain publicly visible and preserved even if you later delete your account. Where the law grants you deletion or de-identification rights, we will honour them as required; however, you acknowledge that the permanence of certain archive records is a core, disclosed feature of the Platform and that some records may lawfully be retained for historical, archival, security, or legal-compliance purposes.

13 Data retention

We retain personal data for as long as needed to operate the Platform, provide your fragments and certificates, comply with legal and tax obligations, resolve disputes, prevent fraud, and preserve the historical archive. Retention periods vary by data type and purpose; public archive records may be retained permanently as disclosed above.

14 Security

We use technical and organisational measures designed to protect personal data, including encryption in transit, access controls, and the use of PCI-DSS-compliant payment processors. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
