Privacy Policy
Last updated: 11 November 2026
BreathMark collects no personal data. It has no accounts, no analytics, no advertising and no tracking, and the app does not send anything about you to us or to anyone else.
To work, BreathMark keeps a few things on your iPhone, and only there:
This data is stored on the device by the app itself (Apple's SwiftData and UserDefaults). It is never uploaded to a server of ours; we don't have one. Like other app data, it may be included in your own iPhone backups (iCloud or your computer), which are under your control.
No name, email, location, contacts, health data, device identifiers, usage analytics or crash reports. BreathMark contains no third-party SDKs, advertising or analytics code, and does not track you across apps or websites.
BreathMark Premium is bought through Apple's App Store. Apple processes the payment; we never see your payment details or your Apple ID. The app only asks the App Store whether Premium has been purchased, to unlock it. Apple's handling of your data is described in Apple's Privacy Policy.
Go to Profile → Reset Stats to clear your practice history, or delete the app to remove everything it stored on your iPhone.
If you email us, we receive your email address and whatever you write, and use them only to reply. We don't add you to any list, and we delete the conversation when it's no longer needed.
BreathMark collects no data from anyone, including children.
This site uses no cookies, analytics or third-party content. Like any website, the server that hosts it may keep standard technical logs (such as IP addresses) for security and operation.
If this policy changes, the new version will be published on this page with a new date.
