Data Retention
Last updated: 27 September 2026
This page explains how long Mindomax keeps your data and when it is deleted. In short: your data stays as long as your account exists and is deleted with it. What we collect and why is described in our privacy policy.
Retention periods at a glance
How long each kind of data is kept:
- Your account, cards, decks, notes, folders and uploaded files: as long as your account exists, or until you delete them yourself
- Review history, streaks, medals and learning statistics: as long as your account exists
- Your conversations with the AI tutor and what AI features create for you, such as cards and notes: stored like the rest of your content
- Sign-in sessions and devices: until you sign that device out or the session expires
- Server request logs used for fair-use limits: kept only as long as needed to apply fair-use limits and stop misuse, then deleted
- Database backups: kept for a limited time, then overwritten
Deleting your account
You can delete your account yourself in the app. This removes both your database entries and the files you stored with us — cards, notes, uploads, annotations, statistics and sessions. It cannot be undone. Backups are kept for a limited time and then overwritten; deleted data disappears from them when they are overwritten.
Deleting single items
You can delete individual cards, decks, notes, folders and files at any time. Backups are kept for a limited time and then overwritten; deleted items disappear from them when they are overwritten.
Server logs
When you use a feature that has a fair-use limit, such as the AI features, we log your user ID, the feature and the time, so that we can count your use and stop misuse. These entries are kept only as long as needed to apply fair-use limits and stop misuse, then deleted. Error logs are kept only as long as we need them to find a fault.
Backups
We back up the database automatically so that we can restore the service after a fault. Backups are kept for a limited time and then overwritten; deleted data disappears from them when they are overwritten. We use backups only to restore data.
