Piu / Privacy

Privacy policy

Last updated November 7, 2026

Piu is built to keep your practice private. Short version: no account, no ads, no tracking, and your practice stays on your devices.

  • No account or sign-up.
  • No advertising and no third-party analytics in the app.
  • Piu does not track you across apps or websites, and does not ask for App Tracking Transparency permission.
  • Your practice history stays on your device, and in your own private iCloud if you use it.
  • We do not sell your data. We do not have your data to sell.

What stays on your devices

Your practice history, your jungle and your settings are stored on your devices. If you are signed in to iCloud, your practice history syncs between your own devices through your private iCloud database, which only you can access. Piu does not send this information to a server run by Kitewren Studio.

Apple Health (optional, off by default)

Piu asks for nothing from Apple Health when you open the app. Each permission appears only when you turn the matching switch on in Settings.

  • Mindful Minutes. With Piu Plus, Piu can write each completed session to Apple Health as Mindful Minutes, including sessions on Apple Watch.
  • State of Mind. On iOS 18 and later, if you rate how you feel in the optional “And now?” step after a session, Piu can save that rating to Apple Health. If you skip the step, nothing is written.
  • Heart rate on Apple Watch. If you turn on “Show heart rate change”, the Watch app reads heart rate readings the Watch has already recorded, near the start and the end of one session, and shows whether it went down. The two readings are shown to you in your History and are not uploaded anywhere.

Piu does not read any other Health data, and does not upload Health data to anyone. Apple Health controls access, and you can change it at any time in the Health app.

Notifications

If you turn on reminders, Piu schedules local notifications on your device. They are not sent through a server run by Kitewren Studio.

Sharing

When you tap Share this breath, Piu makes the image or clip on your device. It leaves your device only when you choose a place for it in the iOS share sheet. Piu does not upload it.

Purchases

Piu Plus is an optional purchase through the App Store. Apple processes the payment. We do not receive or store your card or payment details.
