JagaMata Privacy Policy

Last updated: 30 October 2026

JagaMata is a screen-distance and eye-break reminder app intended to be configured by a parent or guardian. Camera analysis and incident records are processed locally on the device.

Camera processing

JagaMata uses the front-facing camera to estimate face distance. Camera frames are processed in memory by the bundled Google ML Kit face detector and are discarded after analysis. The same frames are used to estimate room brightness for the optional dark-room warning. JagaMata does not save or upload camera frames, face images, or face templates.

Distance estimates are approximate and are not medical measurements.

Data stored locally

JagaMata may store the following on the device:

monitoring preference, distance threshold and detection sensitivity;
child profiles created by the parent: a name or nickname, an optional age, and calibration values (the width of the face as a fraction of the camera frame at two distances — numbers, not images, and not usable to identify anyone);
break-reminder, zikir and low-light-warning preferences;
schedule preferences retained for compatibility while scheduling is being refined;
a salted PBKDF2 hash of the parent PIN, failed-attempt count, and temporary lockout state;
incident records: timestamp, duration, estimated minimum distance, and local date key;
onboarding completion state;
cached Google Play premium-entitlement state.

This local app data is excluded from Android cloud backup and device transfer. It can be removed by clearing app data or uninstalling JagaMata. The app does not currently provide a separate in-app history deletion control.

No internet access

JagaMata does not request the Android internet permission, so the app itself cannot send data off the device. Earlier builds included it indirectly through Google’s ML Kit library, which could send anonymous ML Kit usage logs to Google; it was removed from the app on 11 October 2026.

JagaMata does not include advertising, analytics, tracking, crash-reporting, or developer account SDKs. The developer does not receive camera frames or local incident records.

Optional purchases are processed by Google Play. Google may process transaction and account information under Google’s own terms and privacy policy. JagaMata never receives or stores card or bank details. JagaMata locally caches whether premium access was confirmed, for at most 7 days, so premium features keep working during a short Google Play outage.

Permissions

Camera: estimate face distance in memory.
Display over other apps: display distance and break reminders over other apps.
Foreground service: keep user-initiated monitoring active when Android permits it.
Notifications: display monitoring status, and remind the parent to resume monitoring after the phone restarts.
Run at startup: after a restart or app update, check whether monitoring was on and show that reminder. Android does not allow the camera to be restarted from here.
Wake lock and network state: declared by Android’s WorkManager scheduler library; JagaMata does not use the network.

JagaMata does not request internet, location, contacts, microphone, storage, or battery-optimization exemption permissions.

Data deletion

All JagaMata data is on the device. To delete it, clear the app’s data in Android settings or uninstall the app. There is no cloud copy and no account to delete.

Children’s privacy

JagaMata is designed to be configured and supervised by an adult. It does not contain ads, social features, accounts, or developer-operated collection of children’s personal information. Parents and guardians remain responsible for deciding whether and how the app is used.

Third-party components

Google ML Kit Face Detection: bundled on-device face detection.
Google Play Billing: optional Premium subscriptions (monthly or yearly), and the earlier one-time Premium purchase for existing buyers, processed by Google Play.

Changes

This policy may be updated when app behavior or legal requirements change. The latest published policy should be linked from the Google Play listing.
