Privacy Policy for Evermur

App name: Evermur Package name: com.kirsulab.evermur Publisher: KirsuLab LLC Contact: hello@kirsulab.com

This policy explains what Evermur collects and why. In short: we do not collect your name, email, contacts, photos, or location, there are no ads and no account, and all the sound plays on your device. We use Google Firebase to collect anonymous usage analytics and crash reports that help us understand how the app is used and fix bugs.

1. Data stored only on your device

The following stays locally on your phone and is removed when you uninstall:

• Settings — the selected soundscape, intensity, volume, sleep-timer choice, and the optional brainwave (binaural) preset.

Evermur has no account and stores no personal content.

2. Analytics and crash reporting (Firebase)

Evermur uses two Google Firebase services, which send data to Google (acting as our service provider):

• Firebase Analytics — collects anonymous, aggregated usage data: in-app events (for example, which soundscape was selected), a randomly generated app-instance identifier, your device model and operating-system version, app version, language, and a coarse region derived from your IP address (the IP address itself is not stored by us).
• Firebase Crashlytics — when the app crashes, it collects a diagnostic crash report: the stack trace, device state at the time (model, OS version, memory, app version), and a randomly generated installation identifier.

This data is not linked to your real-world identity, is not sold, and is not used for advertising — there are no ads in Evermur. It is processed by Google in accordance with Google's privacy and security terms (see Google's Firebase privacy documentation and Google Privacy Policy).

3. Permissions

Evermur requests no sensitive permissions: no location, no camera, no microphone, no contacts. Internet access is used only for the Firebase analytics and crash reports described above. A foreground-service / media-playback permission and a wake lock are used only to keep the sound playing with the screen off.

4. Data retention and your choices

Analytics and crash data are retained by Google/Firebase according to our project's retention settings and Google's policies, and are used only in aggregate to improve the app. To request deletion of crash/analytics data associated with your device, contact us at the address below.

5. Children's privacy

Evermur is a general-audience app and does not knowingly collect personal information from children. We do not collect names, emails, or precise location from anyone.

6. Data sharing and selling

We do not sell your data and do not share it with third parties for their own purposes. The only recipient is Google (Firebase), which processes data on our behalf as described above.

7. Changes to this policy

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