1. What never leaves your device
The core data in this app is never transmitted. It is stored only on your device, and it is deleted together with the app.
- The apps you added and the display names you gave them
- Your daily checks and your calendar history
- App settings such as reset time, reminder time, and color
We do not collect this information, and we have no way to view it.
2. About the installed app list
Opening another app straight from the widget is this app's core feature. To make that possible, the screen where you add apps reads the list of apps installed on your device.
- It uses Android's restricted package visibility. Only apps that can be launched from the home screen are visible, and the permission to query every package (QUERY_ALL_PACKAGES) is not used
- The list is used only to display it on screen. It is neither stored nor transmitted
- Only the apps you pick yourself are recorded on your device
The list of installed apps is never sent anywhere.
3. Information we collect
To fix errors and to understand which features are used, we use Google's Firebase services. The information below is sent to Google servers.
| Service | What is collected | Purpose |
|---|---|---|
| Firebase Crashlytics |
Crash records and the location of the error, device model and OS version, app version, and a random installation identifier used to group errors | To find and fix crashes and freezes |
| Firebase Analytics |
App usage events such as screen transitions, an app instance identifier, the advertising ID, device and app version information, and an approximate region (country level) estimated from the IP address | To see which features are actually used and decide what to improve |
We do not collect information that directly identifies you, such as your name, email address, phone number, contacts, photos, or precise location. There is no account creation and no sign-in.
4. Permissions the app requests
| Permission | Why |
|---|---|
| Notifications | To let you know at the time you chose if apps are still left. Turn it off and no reminders arrive |
| Alarms and reminders | To deliver that reminder exactly on time. The app works without it, and only the reminder may arrive up to an hour late |
| Run at startup | Scheduled reminders are cleared when the device restarts, so they have to be set again |
| Internet and network state | To send the diagnostics and statistics described in section 3 |
| Advertising ID | Used by Google AdMob (to show ads) and Firebase Analytics. You can reset or delete it in your device settings |
This app shows banner ads. We use Google AdMob, and the advertising ID is used to select ads and measure their performance. Your app list, checks and history are never used for advertising.
5. Third parties and processing
We do not sell the information we collect, and we do not provide it to third parties. The information in section 3 is processed by the company below in order to provide the service.
- Google LLC (Firebase Crashlytics, Google Analytics for Firebase, Google AdMob)
For how Google handles personal information, please see the Google Privacy Policy and Firebase Privacy and Security.
6. Retention and deletion
Information on your device
It is deleted when you uninstall the app. No separate request is needed.
Transmitted diagnostics and statistics
It is deleted automatically after a period set by Google's retention policy and the Firebase console settings. It is not stored in a form that lets us look up or delete a specific user, so we are unable to act on individual deletion requests.
If you do not want statistics collected
Deleting the advertising ID in your device settings stops the advertising identifier from being collected. Uninstalling the app stops all further transmission.
7. Children under the age of 14
This app is not directed at children, and we do not knowingly collect personal information from children.
