Privacy Policy

Bioluma (荧渊) — Light the deep · Last updated July 20, 2026

Bioluma is a single-player, fully offline game. There is no account, no ads, and no in-app purchases. We do not collect, store, transmit, sell, or share any personal data — by design.

1. What we collect

Nothing. Bioluma does not collect any personal or sensitive information — no names, emails, contacts, location, advertising identifiers, analytics, or usage data. The game requires no account, login, or registration.

2. What is stored on your device

Your game progress and preferences (score, collection, unlocked content, and sound/haptic settings) are saved locally on your device only, using standard iOS local storage. This data never leaves your device, is not accessible to us, and is removed when you delete the app.

3. No advertising, no third parties

Bioluma contains no advertising, no third-party analytics, no tracking SDKs, and no social-media integration. It makes no network requests and works fully offline, so no information is sent to us or to anyone else.

4. No tracking

We do not track you across other companies' apps or websites. Bioluma does not use the Advertising Identifier (IDFA) and will not show an App Tracking Transparency prompt.

5. Children

Because Bioluma collects no data from anyone, no information about children is ever gathered, used, or disclosed.

6. Required Reason API

Bioluma uses Apple's UserDefaults API solely to store your local game progress and settings on the device (declared reason code CA92.1). It is not used for tracking or any other purpose.

7. Changes to this policy

We may update this policy from time to time. Changes will be posted here with a new "Last updated" date.
