Privacy Policy

Effective: September 26, 2026 (last updated: September 29, 2026)

This policy explains what information the iPhone app "BlueBook" (the "App") handles.

This translation is provided for reference. If there is any discrepancy, the Japanese version prevails.

1. Information we collect

The App has no fields for entering personal information such as your name or email address, and it does not require an account.

To improve the App, we use Google Firebase Analytics to collect anonymous usage data such as:

  • Screens viewed and how features are used
  • Device model, OS version and app version
  • Approximate region (country level) and language setting
  • An identifier that Firebase assigns to each app installation

2. Third-party services

The App communicates with the following services to provide its features. Connection information such as your IP address is sent to these services when they are contacted.

Please refer to each service's privacy policy for how they handle information.

3. Data stored on your device

Your favorites and display settings are stored only on your device and are never sent elsewhere. They are removed when you delete the App.

4. How we use information

Usage data is used only to understand which features are used and to improve the App. It is not used for advertising or sold to third parties.

5. Opting out

The App currently has no setting to turn off usage data collection. If you do not wish it to be collected, please stop using or delete the App.

6. Changes to this policy

We may update this policy as the App changes. When we do, we will update the effective date on this page.
