Blue Light: Privacy Policy

Effective 1 November 2026

Blue Light ("the app") is a relaxation and guided visualisation app published by zool on Google Play. This policy explains how the app handles your information.

The short version

Blue Light does not collect, store on any server, share or sell any personal data. It works fully offline and does not have permission to access the internet.

Information stored on your device

To remember your preferences, the app saves a small amount of information locally on your phone: your chosen intention and session length, any intention text you type, sound and display settings, and a history of your sessions (the date, time, length and chosen intention of each session of a minute or more, shown in the optional Pro session history). This information never leaves your device and is not accessible to us. You can remove it at any time by clearing the app's storage in your phone's settings or by uninstalling the app. Pro users can also clear the session history from within the app.

No accounts, ads, analytics or tracking

The app has no user accounts, no advertising, no analytics, no crash reporting and no third-party tracking libraries. It does not request access to your location, contacts, camera, microphone, photos or files.

Children

The app is not directed at children under 13 and does not knowingly collect information from anyone, including children.

Google Play

When you download the app, Google Play may process information under Google's own privacy policy. That processing is handled by Google, not by this app.

Blue Light Pro is an optional one-off in-app purchase. The purchase is handled entirely by Google Play, which talks to the app through the Play Store app on your phone. We never see your payment details. The app only asks Google Play whether Pro has been bought, so it can unlock the Pro features.

Changes to this policy

If this policy changes, the updated version will be posted at this address with a new effective date.
