App Harbour ApS ("we," "us," or "our") operates the Blood Pressure Log: Tracker mobile application, shown in the app as Pressure Diary (the "App"). Your privacy is the whole point of this app, so this policy is short and plain.
The short version
The App stores everything on your device. We do not have a server, we do not have an account system, and we do not collect, transmit, see, or sell your data. Your blood pressure readings stay with you.
Information we collect
None. We do not collect personal information from you. There is no analytics, no advertising, no tracking, and no third-party SDKs in the App.
- Your blood pressure readings, INR results and doses you enter, tags, notes, target ranges, and people (profiles) are saved only in the App's local storage on your device. The App does not sync them to iCloud; they are included in your normal device backups.
- If you turn on the optional daily reminder, the App asks for notification permission and the reminder is scheduled locally by iOS. No reminder data leaves your device. This is the only permission the App requests.
- We do not collect device identifiers, usage statistics, or crash logs.
Your data and exports
When you tap Export, the App creates a CSV file (or, with Premium, a PDF report) from your own readings and hands it to the standard iOS share sheet. You choose what happens next. We are not involved and never receive a copy.
Subscriptions
Purchases (weekly, annual, and lifetime) are processed entirely by Apple through the App Store. We never see or store your payment details. Apple provides us only the anonymous entitlement status needed to unlock premium features on your device.
Health data
The App is a manual logbook for readings you take with your own blood pressure monitor and INR results you enter. It does not read from or write to Apple Health and does not measure blood pressure or INR. Any health information you enter is stored on your device only.
Network use
The App does not contact any server of ours or any third-party service. The network is only used by Apple for purchases, restores and the optional App Store review prompt, and when you tap a link (such as a source for the reference ranges or our support page), which opens in your browser.
Children
The App is not directed to children and does not knowingly collect information from anyone.
Changes
If this policy changes, we will update the effective date above and post the new version at this URL.
