Plain Apps

Privacy policy: Breathe Well [NAME]

Android and iPhone app · Last updated:

1. In short

The app does not collect, transmit or share personal data. It has no account, no ads, no analytics, no tracking and no third-party code that collects data. The app itself makes no network requests. Everything it stores stays on your phone.

One optional feature, off by default, writes your breathing sessions to Apple Health or Health Connect on your phone (see “Apple Health and Health Connect”).

2. Who is responsible

Provider of the app and controller within the meaning of the GDPR: Plain Apps, Residenzstr. 5, 80333 Munich, Germany, plainapps@tuta.com

Contact for privacy questions: plainapps@tuta.com

The full provider details are in the .

The data the app keeps on your phone is not sent to us. We do not receive it.

3. What the app stores on your phone

  • Your sessions: date, time, length, breathing pattern, whether it was completed, and, only if you add them, a note, tags and a mood number before and after.
  • Your own breathing patterns, favourites, recent patterns and settings (for example guidance strength, volume, colours, reminders).
  • Your reminders (time, weekdays, pattern) and a record of an unfinished session, so the app can offer to resume it.
  • A flag per session that it was written to Apple Health or Health Connect, if you turned that on.
  • For the widget and the Live Activity: today's minutes and the running session, kept in storage that only the app and its widget can read.

This data is kept in the app's private storage on your device. We never receive it.

4. Apple Health and Health Connect (optional, off by default)

If you turn on “Save sessions to Apple Health” or “Save sessions to Health Connect” in Settings, your phone asks for permission to write. Each saved session of 20 seconds or more is then written as one mindfulness entry: the real start time, the end time and, on Android, the title “Breathe Well [NAME]: <pattern name>”.

  • The app never reads any Health or Health Connect data.
  • The data is stored by Apple Health or Health Connect on your phone, under their own rules. It is not sent to us, not shared with anyone, and never used for advertising, marketing or data mining.
  • You can switch the setting off at any time and change or revoke the permission in the Health app (iPhone: Health › Sharing › Apps) or in Health Connect (Android: Settings › Health Connect › App permissions).
  • Deleting a session in the app does not delete the entry in Health; you delete it there.
  • Health data you chose to write is not part of the app's own backup: the setting is not restored from a backup.

5. Permissions the app may ask for, and why

Each is asked only when you switch on the feature that needs it.

  • Notifications (reminders): to show your reminders. Reminders are scheduled on your phone, not by a server.
  • Exact alarms / “Alarms & reminders” (Android, optional): so reminders arrive on the minute; without it Android may deliver them up to an hour late.
  • Face ID or fingerprint (optional History lock): your phone's system checks your face or finger; the app only learns “yes” or “no” and never receives biometric data.
  • Health / Health Connect (optional): see above.
  • Audio, vibration, wake lock, foreground service (Android) and background audio (iPhone): so the breathing tones and vibration continue on time with the screen locked, only while you have turned on “Keep guiding when locked” and a session is running.
  • Start on boot (Android): so reminders are set again after a restart.

The app does not use your location, contacts, photos, camera or microphone, and does not read other apps' data.

6. Links to studies

The “About this pattern” pages contain links to published studies. When you tap one, it opens in your phone's browser (a Chrome Custom Tab or Safari), and that website's own privacy policy applies. The app does not send them anything.

7. Files you export

Export and backup create a file only when you ask for it (sessions as CSV or JSON, or a backup file) and hand it to the share sheet of your phone. We do not see it. Files you share are in your hands.

8. Backups by Apple or Google

Your phone's own device backup (iCloud Backup on iPhone, Android Backup to your Google account) may include the app's stored data if you have that switched on. This is done by Apple or Google under your own account settings; we do not receive or read it. You can turn it off in your phone's settings.

9. Medical note

This app is a general-wellness relaxation tool, not a medical device. It does not diagnose, treat, cure or prevent any condition.

10. Third-party code and services

The app is built with Expo and React Native and their open-source libraries, which run inside the app. None of them collects or sends data; the app contains no advertising, analytics or crash-reporting code. The Android app has no internet permission.

Apple Health (HealthKit) and Health Connect are parts of your phone's system, not of this app. The app only writes to them, and only if you switch that on (see above). Face ID, fingerprint checks and notifications are also provided by your phone's system.

11. No tracking, ads or analytics

The app has no account, no advertising, no analytics, no crash reporting and no tracking. It does not use an advertising ID. We do not build profiles and make no automated decisions about you.

12. Legal basis

Nearly everything the app does happens on your phone, and we never receive it. Where that is processing of personal data for which we are responsible, the legal basis is:

  • Art. 6(1)(b) GDPR: the app functions you ask for (the app is used under the terms of the store you got it from).
  • Art. 6(1)(a) GDPR: your consent, for optional features that are off until you switch them on and for which your phone asks your permission. You can withdraw consent at any time by switching the feature or the permission off in the app or in your phone's settings. Processing that already happened stays lawful.

13. How long data is kept, and how to delete it

The data stays on your phone until you delete it. We keep no copy. In the app, go to Settings › Export, back up or delete: you can delete a date range or everything. Uninstalling the app also removes its data from your phone. Entries the app wrote to Apple Health or Health Connect are deleted there.

14. Children

The app is not directed at children and collects no data from anyone, including children.

15. Your rights

Under the General Data Protection Regulation (GDPR) you have the right to:

  • information about and access to your data (Art. 15),
  • correction (Art. 16),
  • erasure (Art. 17),
  • restriction of processing (Art. 18),
  • notification of recipients about corrections, erasure or restriction (Art. 19),
  • receive your data in a common format and pass it on (data portability, Art. 20),
  • object to processing (Art. 21), and
  • withdraw a consent you gave (Art. 7(3)).

You also have the right to complain to a data protection supervisory authority (Art. 77), for example the one where you live. The app makes no decision about you based only on automated processing (Art. 22).

We receive no personal data through the app, so we normally hold nothing about you that we could give out, correct or delete. You can see, export (CSV, JSON, backup file) and delete what the app keeps yourself, in the app; removing the app removes its data from your phone.

If you still want to use one of these rights or have a question, write to the contact address in section 2. We answer within one month (Art. 12(3) GDPR).

16. App stores

If you install the app through Google Play or the App Store, the store processes your download and account under its own privacy policy. We receive only aggregated statistics from the store, no personal data.

17. Changes

If this policy changes, the new version is published at this address with a new date. If a future version of the app starts to access more than described here, this policy is updated before that version is released.
