Zero data. Not "minimal" — zero.

Zen Guard collects no personal data. There is no account system, no cloud sync, no analytics, and no advertising. The app doesn't even have the INTERNET permission — it's physically incapable of transmitting data anywhere.

No sign-up

No tracking

No internet

What we don't do

No data collection

Zen Guard doesn't collect, store, or transmit any personal data. There are no servers.
No analytics or tracking

No third-party SDKs. No usage analytics. No telemetry. No advertising frameworks.
No internet access

The app does not request the INTERNET permission and cannot communicate with any server.
No ads

No ad networks. No monetization of your data. Ever.
No accounts

No sign-up, no login, no email required. Just install and use.
No microphone, camera, or location

None of these permissions are requested. Zen Guard doesn't access your contacts either.

What we do

Local storage only

Settings (alarm sound, vibration, delay) stored in Android SharedPreferences on your device.
Foreground service

Keeps the app running so it can detect when your phone is unlocked while armed. Shows a persistent notification.
Vibration

VIBRATE permission used to vibrate the device when the alarm fires. Configurable in settings.
Notifications

POST_NOTIFICATIONS permission required by Android to show a persistent notification while armed.
Boot re-arm

RECEIVE_BOOT_COMPLETED re-arms the alarm after a device reboot if Zen Guard was armed before shutdown.

We may update this policy as the app evolves. The effective date will change when we do. Continuing to use Zen Guard after that means you accept the updated policy.
