Privacy Policy

Last updated: 15 January 2026

This policy explains how Riznovac collects and uses personal data when you visit our website or use the Platform. We are committed to handling your information lawfully, fairly and transparently.

1. Who we are

For the purposes of the UK General Data Protection Regulation ("UK GDPR") and the Data Protection Act 2018, the data controller is Riznovac, based at High Holborn 211, WC1V 6AA Manchester, United Kingdom. You can contact us about data protection matters at [email protected].

2. Personal data we collect

Depending on how you use the Platform, we may collect:

Identity and contact data, such as your name, email address and telephone number.
Account data, such as login credentials (stored in hashed form), preferences and settings.
Usage data, such as pages viewed, features used, calculator inputs and approximate location derived from IP address.
Technical data, such as device type, browser, operating system and security logs.
Communications data, such as messages you send to our support team.

We do not ask you to provide sensitive special-category data. Please do not send us private keys, seed phrases or wallet passwords under any circumstances.

3. How we use your data

We use personal data to create and manage accounts, provide the Platform, respond to enquiries, detect fraud and abuse, improve our services, meet legal and regulatory obligations, and, where you have opted in, send service updates or marketing messages. We do not sell your personal data.

4. Lawful bases for processing

We rely on one or more of the following lawful bases: performance of a contract with you; compliance with legal obligations; our legitimate interests in running, securing and improving the Platform, balanced against your rights; and your consent where we ask for it. You may withdraw consent at any time without affecting the lawfulness of earlier processing.

5. Sharing your data

We may share personal data with carefully selected service providers who process data on our behalf, including hosting, analytics, customer support and payment providers. These providers are bound by written contracts and may only act on our instructions. We may also disclose data where required by law, by a court order, or to protect the rights and safety of users.

6. International transfers

Some of our providers may process data outside the United Kingdom. Where this happens, we ensure appropriate safeguards are in place, such as adequacy regulations or the International Data Transfer Agreement or Addendum approved by the Information Commissioner.

7. Retention

We keep personal data only for as long as necessary for the purposes described in this policy. Account data is generally retained for the life of your account and for a further period required for legal, accounting or dispute-resolution purposes. Support communications are usually kept for no longer than two years.

8. Your rights

Subject to certain exemptions, you have the right to access your personal data; to have inaccurate data rectified; to have data erased; to restrict or object to processing; to receive your data in a portable format; and to object to direct marketing. To exercise any of these rights, email [email protected]. We may ask you to verify your identity before responding. We will normally respond within one month.

9. Security

We use technical and organisational measures appropriate to the risk, including encryption in transit, access controls, hashed passwords and regular security reviews. No method of transmission or storage is completely secure, so we cannot guarantee absolute security. Please keep your credentials confidential.

10. Cookies and similar technologies

We use strictly necessary technologies to keep the Platform working, and, where permitted, analytics technologies to understand how it is used. Non-essential technologies are used only with your consent, and you can manage your preferences through your browser settings at any time.

11. Children

The Platform is not intended for individuals under 18. We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us so that we can delete it.

12. Changes to this policy

We may update this Privacy Policy from time to time. The revised version will be published on this page with an updated "last updated" date. Where changes are significant, we will notify you by email or through the Platform.

13. Complaints

If you have concerns about how we handle your personal data, please contact us first so that we can try to resolve the matter. You also have the right to lodge a complaint with the Information Commissioner's Office (ico.org.uk), the UK supervisory authority for data protection.
