App Harbour ApS ("we," "us," or "our") operates the Symptom Tracker: Flare Diary mobile application (the "App"). This Privacy Policy explains how your information is handled.
Flare Diary is built to be private. Everything you log, including symptoms, pain levels, body-map locations, migraine attacks, mood, weather, triggers, medications and notes, is stored in the App's storage on your device. It is not sent to us or to any third party, we cannot see it, and we never sell it. The App has no account, no sign-up, no analytics, and no advertising.
Health and log data you enter: Stored in a file inside the App on your device and not transmitted to us or any third party. Weather is something you pick by hand; the App does not use your location or any weather service. If you have iCloud Backup or computer backups turned on for your device, this data is included in those backups like other app data, under your Apple account and Apple's terms. Deleting the App removes this data from the device. You can also delete individual entries inside the App.
Settings: Your reminder time and simple App preferences are stored on your device.
Automatically collected information: None. There is no analytics, no tracking, no advertising identifiers, and no third-party SDKs. The App does not request access to your camera, photos, location, contacts or Apple Health.
Subscription information: Purchases are processed by Apple through the App Store. We never receive or store your payment details. Subscription status is verified on-device by Apple's StoreKit.
Because your data is not sent to us, we do not use it for any purpose. Your entries are used only to display your timeline, insights and exports to you, on your device.
We do not collect your data, so there is nothing for us to share, sell, trade, or rent. Exports (PDF or CSV) are generated on your device and shared only if you choose to send them through the iOS share sheet. Links in the App (for example the NHS migraine page cited in Insights, or our support pages) open in your browser and are subject to those websites' own policies.
If you enable the optional daily reminder, the App asks for notification permission and schedules a local notification on your device. This involves no server.
Your data is retained on your device until you delete it or remove the App. We hold no copy.
Flare Diary is a personal log for informational purposes only. It is not medical advice, a diagnosis, or a measuring device, and it is not a substitute for professional care.
The App does not collect personal information from anyone, including children.
We may update this Privacy Policy from time to time. Changes will be posted here with an updated date.
