1. Information processed on-device
Uhh processes application package names and labels, app categories, usage start and end times, usage duration, launch counts, blocks prevented, selected applications, focus schedules, Quick Focus and Pomodoro state, and Uhh PRO entitlement status. No Uhh account, username, or password is required.
2. Why this information is used
The information is used only to display local screen-time analytics, determine whether a user-selected application should be blocked, run schedules, Quick Focus, and Pomodoro, maintain retention limits, create an encrypted backup at the user’s request, and restore a Google Play subscription entitlement.
3. Android permissions
| Android Permission | Operational Scope & Purpose |
|---|---|
PACKAGE_USAGE_STATS(Usage Access) |
Identifies the active application and its usage duration, including while focus protection runs in the background. It does not read message contents, keystrokes, passwords, or screenshots. |
SYSTEM_ALERT_WINDOW(Display over other apps) |
Displays the focus overlay only when a selected application is opened during an active schedule, Quick Focus, or Pomodoro focus session. |
FOREGROUND_SERVICE & Notifications |
Keeps user-enabled protection perceptible through an ongoing notification. |
RECEIVE_BOOT_COMPLETED(Boot completed) |
Restores protection after a restart when onboarding was previously completed. |
Permissions can be revoked in Android Settings. Related features cannot operate while a required permission is disabled.
4. Storage, transfer, and sharing
- Usage history, schedules, selected applications, and entitlement cache remain in Uhh's private app storage.
- Uhh does not automatically upload usage data. If you explicitly create an encrypted backup, Android’s document picker sends the AES-256-GCM encrypted file to the location you choose, which may include Google Drive or another document provider.
- The backup passphrase is not stored by Uhh and cannot be recovered. Google Drive or another selected provider processes the encrypted file under its own privacy terms.
- Uhh does not sell or share app-usage history and does not use it for advertising or cross-app tracking.
- Uhh currently contains no advertising SDK.
5. Google Play Billing
Optional Uhh PRO purchases are processed by Google Play. NayaBisa does not receive or store card or bank details. The application receives purchase and subscription status from Google Play to provide or restore PRO access. Google's processing is governed by the Google Privacy Policy.
6. Retention and deletion
Raw sessions are retained for up to 7 days, hourly aggregates for up to 30 days, and daily aggregates for up to 90 days on Free or 365 days on Uhh PRO. Users can delete all local Uhh data through Android Settings > Apps > Uhh > Storage > Clear data, or by uninstalling Uhh.
7. Security
Uhh uses Android application sandboxing, disables cleartext network traffic, and limits exported application components. User-created backups use AES-256-GCM authenticated encryption with a password-derived key, random salt, and random initialization vector. No method of storage is guaranteed to be absolutely secure, but Uhh minimizes data scope and does not perform automatic usage-history uploads.
8. Children's privacy
Uhh is not directed to children under 13 and does not knowingly request identifying account information from children.
9. Changes
This policy may be updated when Uhh's features or legal obligations change. The effective date on this page will be updated when material changes are published.
