Here is the Privacy Policy for your app Immerse, translated into English and tailored to your specific tech stack (Supabase, Google Auth, and Local SQLite).

PRIVACY POLICY
Last updated: March 10, 2026

This Privacy Policy describes how the "Immerse" application (hereinafter referred to as the "Application") collects, uses, and protects your information when you use our reading tracking and synchronization services.

By using the Application, you agree to the collection and use of information in accordance with this Privacy Policy.

1. INFORMATION COLLECTION AND USE
The Application is designed to help you manage your personal library and reading progress. To provide cross-device synchronization, we process the following data:

Authentication Data: When using Google Sign-In, we receive your unique user ID (UID), name, and email address to create and manage your account.

Library Data: We store information about the books you add (book identifiers) and your reading progress (current page, completion status, total pages).

Local Storage: Some data is stored locally on your device in an SQLite database to ensure offline access and performance.

2. THIRD-PARTY SERVICES
To provide cloud synchronization and secure authentication, the Application uses the following third-party services:

Supabase: Used as the primary cloud database and authentication service. Data is stored on secure Supabase servers. Supabase Privacy Policy.

Google Play Services / Google Sign-In: Used for secure user authentication. Google Privacy Policy.

Google Books API: May be used to fetch book metadata (title, author, cover image) upon user request.

3. DATA RETENTION AND DELETION
We retain your data only for as long as your account is active.

Data Deletion: You have the right to sign out or contact us to request the permanent deletion of your profile and all associated library data from our servers.

4. SECURITY
We take commercially reasonable measures to protect your data. The use of Supabase ensures that data is encrypted in transit and protected by Row Level Security (RLS), ensuring that only you can access your personal library data.

5. CHILDREN'S PRIVACY
The Application is not intended to knowingly collect personal data from children under the age of 13. If you are a parent or guardian and are aware that your child has provided us with personal data, please contact us.

6. CHANGES TO THIS PRIVACY POLICY
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new version on this page or within the Application's store description.
