Privacy Notice

1 Information We Collect

a. User-Provided Information

The App may ask you to provide a name.

• This information is stored locally on your device only
• It is used solely for in-app personalization
• It is not transmitted, shared, or uploaded to any server

Providing a name is optional.

b. Book Information

When you search for books or add books to your collection, the App retrieves book metadata (titles, authors, covers, descriptions) from the Google Books API.

• Search queries are sent to Google's servers to retrieve results
• Book data you save is stored locally on your device
• We do not store or track your search history on our servers

c. Analytics Data

The App collects anonymous usage data to help improve functionality and stability. This data may include:

• App usage events (screens viewed, features used)
• Device or app instance identifiers
• Crash and performance information
• General device information (OS version, device type)

This data does not include user-provided names, book collections, or other personally identifiable information.

Analytics are collected using PostHog, which acts as a data processor on our behalf.

• Improve the App's performance and features

3 Legal Basis for Processing

We process analytics data based on our legitimate interests in:

• Understanding how users interact with the App

• Book search queries are processed by Google (see their Privacy Policy)

International Data Transfers

Depending on your location, you may have rights under data protection laws, including:
