Privacy policy
1. Introduction
We take the privacy of your data very seriously. This policy describes how the Maths & Calculs app handles information. In short: no personal data is collected, stored on a server or shared with third parties.
2. Data processed
The values you enter (numbers, equations, amounts, rates…) are used only to perform the requested calculation, in memory, on your device. No calculation history is kept.
The only information saved is your theme choice (light, dark or system), stored locally in the app's preferences.
3. No data transmission
The app does not need the Internet to work and sends no data to external servers or third parties. It contains no ads, no analytics and no trackers.
4. Permissions
The app requests no intrusive permissions: no access to contacts, camera, microphone, location or your files.
5. Android backup
Depending on your device settings, Android's automatic backup may include the theme choice in your Google account backup. This backup is managed by Google and your device, not by us; it contains no personal data.
6. Contact by email
If you use the "Suggest an improvement" button, your email app opens with a pre-filled message. Nothing is sent without your action: the information you choose to send (your email address and message) is used only to reply to you.
7. Data deletion
Since no data is stored on a server, there is nothing to request for deletion. To erase the theme choice saved on your device:
- Open your device settings.
- Select "Apps" or "Application manager" depending on your device.
- Find and select the "Maths & Calculs" app.
- Go to "Storage".
- Choose "Clear data".
Uninstalling the app also deletes all its local data.
8. Contact
