Privacy Policy

Last updated: February 15, 2026

1. Data Collection

Local Storage: Booru Prompt Gallery primarily uses your browser's Local Storage to save your favorites, history, and application preferences. This data stays on your device.

Analytics: We use Vercel Analytics to collect anonymous usage data to help us improve the tool. This includes information about which features are used most frequently, but does not include personally identifiable information.

2. Authentication & Account Data

When you choose to sign in to Booru Prompt Gallery, we use Magic Link (passwordless email) as our authentication provider. We are committed to data minimization and only request your email address.

How we use this data: Your email address is used solely as a unique identifier to link your account to your saved preferences, favorites, and history across devices. We do not share your email with third parties or use it for marketing purposes.

3. Third-Party Services

This application interacts with external APIs (Danbooru, Rule34, etc.) to fetch images and tags. When you browse the gallery, your IP address may be visible to these third-party providers as part of the standard web request process.

We recommend reviewing the privacy policies of the booru providers you choose to use within the app.

4. Cookies

We do not use tracking cookies for marketing purposes. We use functional cookies required for authentication and server-side features to maintain your session securely.

5. Contact

If you have any questions about this privacy policy or how your data is handled, you can reach out via the Feedback tool in the application.
