The short version
One Breath is a breathing practice app. It has no account, no analytics, no advertising and no tracking, and it never connects to a server run by the developer. Everything you do in One Breath stays on your iPhone and, if you use it, your Apple Watch. The developer cannot see your sessions, your ratings or your settings, because they are never sent to the developer.

Information we do not collect
The developer does not collect, receive or store any of the following:
- Name, email address, phone number or physical address
- Contacts, photos, location, or microphone or camera input (One Breath uses none of these)
- Health data of any kind
- Payment card or financial account information
- Advertising identifiers or device identifiers used for tracking
- Analytics, crash reports collected by the developer, or usage behaviour
Information stored on your devices
To work, One Breath keeps the following on your own devices only:
- Your settings (chosen technique, session length, haptics, sound guide, appearance and similar preferences)
- A history of your breathing sessions: date and time, technique, length and number of breaths
- If you choose to answer "How do you feel?" after a session, the before-and-after rating you picked (on a five-step scale from tense to calm). These ratings are used only to show you which techniques help you most, on your iPhone
- Breathing rhythms you create yourself
- The reminder times you set
A small summary (your current technique and minutes this week) is shared with One Breath's own widgets through an App Group on your device so the widgets can show it. None of this information is transmitted to the developer or to any third party. Your iPhone's own backups may include it, as they do for any app.
Apple Watch (optional)
If you use One Breath on Apple Watch, your iPhone sends your own breathing rhythms, your wrist-haptic setting and whether your Apple Account owns One Breath Complete to your watch, and your watch sends each finished session back to your iPhone so it appears in your history. This transfer uses Apple's Watch Connectivity framework and goes directly between your own iPhone and Apple Watch. It never passes through a server run by the developer, and the developer never receives it.
During a session on Apple Watch, One Breath uses a mindfulness session so the haptic guidance continues with the screen off. It does not read your heart rate or any other health or sensor data.
Apple Health (optional)
If you turn on Save to Apple Health in One Breath's settings, iOS asks for your permission, and One Breath then writes each finished session to Apple Health as Mindful Minutes (start time and end time). One Breath only writes this one type of data; it never reads anything from Apple Health. The data goes from One Breath to the Health app on your device and is not sent to the developer. It is never used for advertising, marketing or data mining. You can turn this off at any time in One Breath's settings or in the Health app.
Notifications (optional)
If you add a reminder, iOS asks for permission to show notifications. Reminders are scheduled locally on your iPhone at the times you choose. No notification is sent from a server.
Lock Screen, widgets, Siri and Shortcuts
While a session runs, One Breath can show the technique and time remaining on your Lock Screen and in the Dynamic Island (a Live Activity). Widgets, the Control Center control and Siri phrases only open One Breath and start a session. All of these are local iOS features; none of them send data to the developer.
Purchases
One Breath Complete is a one-time purchase processed by Apple through the App Store. The developer never receives your payment details. The app asks the App Store whether your Apple Account owns the purchase so it can unlock it on your devices.
Third parties
One Breath contains no third-party SDKs, analytics services, advertising networks or tracking code. The developer does not sell, rent, trade or share any user data, because no user data is collected.
Deleting your data
You can delete individual sessions or your whole history in History, delete rhythms you created, and remove reminders in Settings. Deleting the app removes everything it stored on your iPhone; deleting it from your Apple Watch removes what it stored there. Mindful Minutes already saved to Apple Health stay in Health until you delete them there.
Children
One Breath does not knowingly collect personal information from anyone, including children, because it does not collect personal information at all.
Not medical advice
One Breath is a relaxation and breathing practice tool. It is not a medical device and does not diagnose, treat or prevent any condition. If you feel dizzy or unwell while breathing, stop and breathe normally.
Changes to this policy
If a future version changes how information is handled, this page will be updated and the date above will change.
