Privacy policy
Camera Guard is an Android app that watches whether a camera is in use and alarms you if it stops. It is built to need as little from you as possible: no account, no analytics, no advertising, and no server.
Last updated: 21 September 2026.
The short version
Camera Guard collects no personal data. Nothing you do in the app is transmitted to us or to anyone else, because the app has no backend and makes no network requests of its own.
Your camera
Camera Guard never accesses your camera, and it does not request the camera permission — you can confirm that in the permission list on this app’s Play Store page. Instead it reads Android’s camera availability signals, which report whether a lens is currently busy without opening it. No photo, video or audio is ever read, recorded, or uploaded.
What is stored, and where
Two things are saved locally on your device only:
- Your guard settings — warm-up seconds, end time, check interval, alarm and camera options.
- The current guard state — so that a guard can resume, alarm included, if Android restarts the app.
Neither leaves your phone. Both are deleted when you uninstall the app or clear its data.
Permissions, and why each one is asked for
- Notifications —
POST_NOTIFICATIONS
shows the ongoing “guarding” notification, which Android requires for a foreground service. You can deny it; the guard still runs. - Foreground service —
FOREGROUND_SERVICE,FOREGROUND_SERVICE_SPECIAL_USE
keeps the watchdog alive while you are in another app or the screen is off. The notification above is how Android keeps this visible to you. - Vibration —
VIBRATE
vibrates the alarm pattern. - Audio settings —
MODIFY_AUDIO_SETTINGS
raises the alarm stream to maximum while guarding, and restores your original settings afterwards. - Battery optimisation —
REQUEST_IGNORE_BATTERY_OPTIMIZATIONS
asks to be exempt from Android’s battery killing, which would otherwise stop the guard. Requested in-app, and optional. - Do Not Disturb —
ACCESS_NOTIFICATION_POLICY
lets the alarm be heard past Do Not Disturb. Granted by you in system settings, and optional. - Internet —
INTERNET
comes from the React Native/Expo runtime the app is built on. Camera Guard’s own code makes no network requests, and the app has no server.
Camera Guard does not request storage access, and does not draw over other apps.
What we do not do
- No account, sign-in, or profile.
- No analytics, telemetry, or usage tracking.
- No advertising, and no advertising SDK.
- No crash-reporting SDK — crash data does not leave your device.
- No location, contacts, calendar, microphone, or camera access.
- No selling or sharing of data, because none is collected.
Children
Camera Guard is a general-purpose utility and is not directed at children. It collects no data from anyone, including children.
Changes to this policy
If a future version of the app starts collecting anything — for example if advertising or optional cloud features are ever added — this page will be updated before that version ships, and the change will be noted in the app’s release notes.
