Privacy

Last updated: 25 October 2026

Atelas does not collect, share or sell any personal data. There are no accounts, no ads, no analytics and no tracking. The app works fully offline and sends nothing anywhere.

Data on your phone

Your sessions (date, technique, length), the moods you choose to record before and after a session, your milestones, your own breathing patterns and your settings are stored only on your phone.

Widgets, shortcuts and voice

The home screen and lock screen widgets show your streak and today's minutes from data stored on your phone. On iPhone, starting Quick calm, Sleep or Focus is offered to Siri as a suggestion; Siri keeps these suggestions on your device. On Android, Google Assistant can open these sessions by voice; Atelas itself receives only the request to start one.

Backups

If backups are turned on for your phone, the operating system may include Atelas' session history and settings in your Google (Android) or iCloud (iOS) backup, so they come back when you reinstall the app. These backups are handled by Google or Apple under their own privacy policies; Atelas has no access to them.

Notifications

The daily reminder is a local notification scheduled on your phone. No server is involved.

Exporting and ratings

Settings → Export data creates a CSV file of your sessions and opens the system share sheet; the file goes only where you choose to send it. Atelas may show the App Store or Google Play rating prompt; that prompt is provided by Apple or Google.

Deleting your data

Use Settings → Delete all data in the app, or uninstall the app, to delete everything it stored.

Contact

Questions? Email atelas@supudo.net. Settings → Send feedback in the app opens your own email app; nothing is sent unless you send that email. We use what you write only to answer you.
