Privacy Policy

Effective date: 11 November 2026 · Applies to the Prana Rhythm apps for Android, Wear OS, iOS and watchOS.

1. Who we are

Prana Rhythm is made by Suthee Phaiphinit, an individual developer based in Thailand (“we”, “us”). For personal data we receive (the emails you send us, see section 7, and the stores’ records of tips, see section 6) we are the data controller under Thailand’s Personal Data Protection Act (PDPA).

2. Data stored on your device

To work, the app keeps the following in its private storage on your phone and, if you use one, your watch:

• Practice history: for each session of 30 seconds or more, the pattern you used, when it started, your local date and time zone offset, the planned and actual length, any cool-down, the number of cycles, how it ended, and whether it ran on your phone or watch.
• Your patterns: breathing patterns you create or edit.
• Reminders: the times and days you choose.
• Settings: language, theme, sound and vibration choices, your last session setup, whether you saved sessions to Health, and which version of the safety notice you have read.

This data never leaves your devices except in the ways described in sections 4 to 6, all of which you control. We cannot see it.

3. What we collect

Nothing through the app. It does not connect to any server of ours, and we have added no advertising, analytics, crash-reporting or tracking code; it does not use advertising identifiers. So that you can leave a tip, the Android app includes Google’s Play Billing Library. That library needs internet access and may send Google technical information about how it is working, which Google handles under its own privacy policy.

4. Health Connect and Apple Health

Saving to Health is off until you turn it on in Settings and grant permission.

• What is written: each counted session as a mindfulness (Android) or mindful minutes (iOS) entry: start and end time with your time zone, the pattern’s name, whether it was practised on your phone or watch, and an ID the app uses to find the entry again if you delete the session.
• What is read: nothing. The app asks only for permission to write.
• Deleting: when you delete a session in History, the app also removes it from Health.
• Turning it off: switch it off in the app’s Settings, or remove the app’s access in Health Connect or the Health app at any time. Entries already saved stay in Health until you delete them there.

Health data is never used for advertising, never sold, and never shared with anyone. Data in Health Connect and Apple Health is stored by Google and Apple under their own privacy policies. The use of information received from Health Connect adheres to the Health Connect Permissions policy, including the Limited Use requirements.

5. Phone and watch

If you use the watch app, your phone sends it your theme, patterns and last session setup, and the watch sends sessions you practise on it back to your phone. This uses the system link between your own paired devices: Wear OS Data Layer on Android and Watch Connectivity on Apple devices. When the devices are not close to each other, Google or Apple may carry this data through their own services. It is not sent to us.

6. Backups, notifications and app stores

• Backups: if device backup is on (Google backup on Android, iCloud Backup on iOS), your phone’s system may include the app’s data in that backup, stored in your own Google or Apple account. You control this in your device settings.
• Notifications: reminders and the “practice in progress” notification are created on your device. No notification service of ours is involved.
• App stores: Google Play and the App Store give developers statistics such as install counts, and crash reports if you agreed to share diagnostics with Google or Apple. These are aggregated or anonymous and do not identify you. See Google’s and Apple’s privacy policies for what they collect.
• Tips: tips in the app’s Store are paid through Google Play or the App Store with your Google or Apple account. The payment is between you and Google or Apple, and we never see your card or bank details. For each tip, Google and Apple give us records such as an order number, which tip, the price, the date and the country. We use them only for accounting and refunds, and keep them as long as tax law requires. The app keeps no record of your tips, and a tip unlocks nothing.

7. If you email us

If you write to [email protected], we receive your email address and whatever you include. We use it only to reply to you, on the basis of your request. We delete support emails within 24 months after the conversation ends, unless we must keep them longer by law. Email to our domain is forwarded by Cloudflare Email Routing to our mailbox.

8. Your choices and rights

Because your app data is on your devices, you are in full control of it:

• Delete single sessions in History, or delete patterns and reminders in the app.
• Delete everything by clearing the app’s data or uninstalling the app on each device.
• Withdraw Health permission at any time, as described in section 4.

Under the PDPA, and similar laws such as the GDPR where they apply, you have the right to access, correct, delete, restrict or object to the processing of your personal data, to receive a copy of it, and to withdraw consent. For data we hold (support emails and records of tips), contact us and we will respond within 30 days. You may also complain to Thailand’s Personal Data Protection Committee, or to the data protection authority where you live.

9. Children

Prana Rhythm is made for adults and is not directed at children under 13. The app collects no data from anyone, including children.

10. Security

App data is kept in the app’s private storage, which other apps cannot read, and is protected by your device’s own security. Using a screen lock on your phone and watch keeps it safer.

11. Changes to this policy

If the app starts handling data in a new way, we will update this page and its effective date before that version is released, and point out important changes in the app.
