Privacy Policy

Effective date: 2026-09-20

Atem (“the App”) is an offline breathing timer developed by Robin Weser (“we”, “us”). The App is designed to work fully offline. We do not run servers for Atem and we do not collect, transmit, or sell your personal data.

Summary

  • No accounts. No registration required.
  • No tracking. No analytics, no ads.
  • Works fully offline. Optional Atem Pro uses Apple or Google and RevenueCat only to verify a one-time purchase.
  • Your data stays on your device. Sessions, custom patterns, and programs are stored locally.
  • Encrypted storage. Session and custom-flow data is stored encrypted on your device.
  • Not a medical device. Atem is a personal timer and does not diagnose or treat any condition.

1) What data the App stores on your device

Sessions
When a session lasts at least 15 seconds, the App can store a local log entry (kind, pattern or program name, duration, timestamps). Session payloads are stored in an encrypted local database.

Custom patterns and programs
If you create your own breathing flows, those definitions are stored encrypted on your device.

Settings
Language, appearance, reminder times, and similar preferences are stored locally on your device.

Encryption key
An encryption key is stored in the device’s secure storage so the App can encrypt and decrypt your local data. The key never leaves the device.

2) What we do not collect

We do not collect names, emails, health data, analytics events, crash reports, advertising identifiers, or payment information. Optional Atem Pro is a one-time in-app purchase processed by Apple or Google. Atem has no accounts.

3) Backups you export

You can export a .zip backup (password-protected or unencrypted). You choose where that file goes. An unencrypted backup can be read by anyone with the file. Importing a backup replaces local data after you confirm.

4) Device backups

Your operating system may include app data in iCloud or Google device backups, depending on your device settings. That is controlled by you and your device, not by Atem. Atem does not upload your data itself.

5) Notifications

Optional local reminders are scheduled on your device. They are off by default. Granting notification permission does not send data to us.

6) In-app purchases

Optional Atem Pro is a one-time in-app purchase that currently unlocks multiple reminders. Custom flows are planned as a future Pro feature. Purchases are processed by the app store provider (Apple App Store or Google Play) and RevenueCat, which verifies entitlement status. We do not receive your payment details. Those providers may process personal data as described in their own privacy policies.
