Privacy Policy

The Core Principle: We Collect No Personal Data

Our application is built on a "privacy-by-design" principle. The fundamental feature of Only One is that all data you provide, including images of your loyalty cards and any associated names, is stored exclusively in your browser's local storage on your own device.

This means:

• Your data is never uploaded to our servers.
• We do not have access to your cards or any information you store.
• We do not track your usage of the app.
• We do not require you to create an account.

Your Rights Under UK GDPR

As a UK-based service, we respect your rights under the UK General Data Protection Regulation (GDPR). Since we do not collect, process, or store any of your personal data, your rights are managed directly by you:

• Right of Access: You can access your data at any time by opening the app.
• Right to Rectification: You can edit or update your cards directly within the app.
• Right to Erasure ('Right to be Forgotten'): You can delete individual cards at any time. To erase all data, simply clear your browser's cache and site data for our website. This action is permanent and irreversible.

Cookies

This website does not use cookies for tracking or advertising purposes. The only data storage mechanism used is your browser's local storage, which is essential for the app's core functionality of saving your cards on your device.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes.
