Privacy Policy
Effective date: 22 October 2026 · Last updated: 22 October 2026
The short version
- Estimeter does not collect any personal data. We have no servers, accounts, analytics, advertising or tracking.
- Everything you enter stays on your device. Your tasks, timings, notes and insights are stored only in the app's private storage.
- Nothing is shared or sold, because nothing is sent to us or to anyone else.
- You are in control. You can export your data or delete it at any time from inside the app.
1. Who this policy covers
This policy explains how the Estimeter mobile app ("Estimeter", "the app", "we") handles information on Android and iOS. By using the app, you agree to this policy.
2. Information stored on your device
To work, Estimeter saves the following information locally on your device only. It is never uploaded to us.
| What | Why |
|---|---|
| Tasks you create: titles, descriptions, checklists, categories, priorities, due dates, start times and repeat settings | To show and plan your tasks |
| Your time estimates and the time you actually tracked (timer sessions and pauses) | To compare estimates with actual time |
| Reflections you choose to record (for example, why a task took longer) and notes | To show patterns in your insights |
| Templates, daily focus goal, streaks and app settings | To remember your preferences |
| Optional profile details you type in (display name, email, role, avatar choice) | To personalise the app. These are optional and stay on your device; we never receive them |
| Estimate suggestions and the personal estimation model | Calculated on your device from your own history to suggest realistic times. The model never leaves your device |
3. Information we do not collect
Estimeter does not collect, transmit or store on any server:
- your name, email, contacts, photos, location or device identifiers;
- usage analytics, crash reports or advertising identifiers;
- any of the task or timing data described above.
The Android app does not request internet access, and the app contains no analytics, advertising or tracking SDKs. Fonts and all other resources are bundled inside the app, so it does not contact any server while you use it.
4. Device permissions and features
Estimeter asks only for permissions it needs. You can change them at any time in your device settings.
| Permission / feature | How it is used |
|---|---|
| Notifications | Timer alerts (approaching or reaching your estimate, overtime), break reminders, start-time reminders and the optional daily planning reminder. Created on your device. |
| Exact alarms and "run at startup" (Android) | So timer alerts arrive on time, and are rescheduled after your phone restarts. |
| Face ID, Touch ID, fingerprint or passcode | Only if you turn on App Lock. Verification is done by your device's operating system. Estimeter never receives or stores biometric data. |
| Vibration and keep-screen-awake | Haptic feedback and keeping the screen on while a timer is open. |
| Home-screen widget and Live Activity (iOS) | Shows your current or next task. The app shares a small summary with the widget through your device's local storage. It is not sent anywhere. |
| Files and share sheet | Only when you choose to export or import a backup. See section 5. |
5. Backups, exports and device backups
Exports you create
You can export a backup (JSON) or a spreadsheet (CSV) from the Me tab. The file is created on your device and handed to your system share sheet. Where it goes next (for example, a cloud drive, email or messaging app) is your choice and is governed by that service's privacy policy. When you import a backup, the app reads only the file you pick.
Operating-system backups
If you have device backups turned on (such as Android backup to your Google account, or iCloud/iTunes backup on iOS), your operating system may include Estimeter's data in that backup. These backups are managed by Google or Apple under your account and their privacy policies; we cannot access them.
6. Sharing and selling of data
We do not sell, rent, share or disclose your information to anyone, because we do not receive it. There are no third-party services in the app that process your data.
7. Security and retention
Your data is kept in the app's private storage, protected by your device's security. You can add App Lock for extra protection. Data stays on your device until you delete it.
8. Your choices and rights
- Access and export: view everything in the app, or export it from Me → Your Data.
- Delete: use Me → Reset All Local Data, or uninstall the app, which removes all of its data from your device.
- Notifications and permissions: turn them off in the app or in your device settings.
Because we hold no personal data about you, there is nothing for us to access, correct or delete on our side. Rights under laws such as the GDPR, UK GDPR and CCPA/CPRA can be exercised directly in the app as described above. You are welcome to contact us with any question.
9. Children
Estimeter is not directed to children under 13. The app does not knowingly collect personal information from anyone, including children.
10. Changes to this policy
If the app's data practices change (for example, if an optional sync feature is added), we will update this page and the "Last updated" date before the change takes effect, and describe the change in the app's release notes.
