This Privacy Policy explains how ryden.systems ("we", "us", "our") collects, uses, and protects your personal data in accordance with the General Data Protection Regulation (GDPR) and applicable EU data protection laws.
ryden.systems is the data controller responsible for your personal data.

We do not collect traditional personal identifiers such as names or email addresses. Accounts are created and authenticated solely through ownership of a Solana wallet address. No password or personal profile is created.
The data we store and process is as follows:
| Data | Source | Purpose |
|---|---|---|
| Solana wallet address | Provided by you at sign-in | Account identity, subscription status, and payment matching |
| Payment information (name, billing address, etc.) | Collected by Stripe directly from you | Subscription billing — required by Stripe based on your country of residence |
| Blockchain payment records | Solana public ledger | Matching on-chain crypto payments to your account |
| Usage data (anonymized) | Your interactions with the app | Understanding how the service is used — wallet addresses are never included in or linked to analytics data |
| IP address (anonymized) | Your browser | Security — full IP addresses are not stored |
| Processing activity | Legal basis |
|---|---|
| Wallet-based account management & service delivery | Performance of a contract (Art. 6(1)(b)) |
| Fiat payment processing (via Stripe) | Performance of a contract (Art. 6(1)(b)) |
| Crypto payment matching (on-chain) | Performance of a contract (Art. 6(1)(b)) |
| Retention of payment records | Legal obligation (Art. 6(1)(c)) |
| Security and fraud prevention | Legitimate interests (Art. 6(1)(f)) |

We use your data to:
We share data only with trusted processors who are contractually bound to protect it.
Stripe — Payment processing
When you pay by card, Stripe collects your payment information (which may include name, email address, and billing address) directly from you. ryden.systems does not store card numbers. Stripe is certified to PCI DSS standards and acts as an independent data controller for the payment data it collects. ryden.systems has access to the customer information and the associated wallet address recorded in its Stripe account and uses it solely for billing and legal compliance. Stripe operates under its own Privacy Policy: https://stripe.com/privacy
Matomo Analytics (self-hosted) — Usage analytics
We use a self-hosted instance of Matomo for analytics. Your data is stored on our own servers and is not shared with any third party. IP addresses are anonymized before storage. Wallet addresses are never passed to or recorded by Matomo — analytics sessions have no knowledge of your identity. Matomo is configured to respect Do Not Track browser settings.
We do not use Google Analytics or other third-party analytics platforms that transfer your data outside our control.
| Data type | Retention period |
|---|---|
| Wallet address & subscription status | Until an erasure request is fulfilled, or 7 years after last subscription |
| Payment records (Stripe data, crypto payment refs) | 7 years (legal/tax obligation — not subject to erasure requests) |
| Anonymized analytics | Retained indefinitely — this data cannot be linked to any individual and falls outside the scope of GDPR (Recital 26). No re-identification is possible. |
Our services are hosted within the European Economic Area (EEA). If any data is transferred outside the EEA (e.g. via Stripe), it is subject to appropriate safeguards such as Standard Contractual Clauses (SCCs) as required by GDPR.
We use only session cookies required for the service to function. Our self-hosted Matomo analytics uses a first-party cookie that you can opt out of via your browser's Do Not Track setting.
Stripe may set its own cookies for fraud prevention and secure payment processing. These are functional, security-purpose cookies set by a third party and are not used for advertising. They are governed by Stripe's cookie policy.
We do not use advertising or tracking cookies.
As an EU resident, you have the right to:
To exercise any of these rights, contact us at support@ryden.systems. We will respond within 30 days.
To request erasure of your data (deletion of your wallet address and subscription records from our systems), email support@ryden.systems. See Section 6 for details on what can and cannot be deleted.
You also have the right to lodge a complaint with your national data protection authority (e.g. CNIL in France, BfDI in Germany, or the authority of your EU country of residence).
We implement appropriate technical and organizational measures to protect your personal data, including encryption in transit (HTTPS/TLS), access controls, and regular security reviews.
Our service is not directed at children under 16. We do not knowingly collect personal data from children. If you believe a child has created an account, contact us immediately at support@ryden.systems and we will delete the associated data.
We may update this Privacy Policy from time to time. We will notify you of material changes via an in-app notice at least 30 days before the changes take effect. The "last updated" date at the top of this page reflects the most recent revision.
