Effective date: July 12, 2026
Attune is built on a simple principle: your health data never leaves your device.
No personal or health data. Attune has no accounts and no sign-up. Everything you log — hot flashes, doses, symptoms, notes — and everything read from Apple Health stays on your iPhone in the app's private database and is never sent to us. The only thing we collect is a small set of anonymous usage events, described under Analytics below.
With your explicit permission, Attune reads sleep, heart rate, resting heart rate and heart rate variability from Apple Health to display trends alongside your logs. This data is processed entirely on your device. Attune never writes to Apple Health and never transmits Health data anywhere. Health data is never used for advertising or shared with third parties, in accordance with Apple's HealthKit guidelines.
Events you log on Apple Watch are transferred directly to your paired iPhone using Apple's on-device Watch Connectivity — not over the internet.
Purchases are processed by Apple. Attune verifies your subscription on-device through StoreKit and receives no payment details, name, or address. See Apple's Privacy Policy for how Apple handles purchase data.
Dose reminders and check-ins are scheduled locally on your device. No push servers are involved.
Attune sends a small set of anonymous usage events (for example, "onboarding completed" or "report exported") to our own server so we can improve the app. These events contain a random install identifier, the app version and your language — and never any health data, names, emails, or device identifiers. The identifier is not linked to you and resets if you reinstall the app. We use no third-party analytics SDKs and no advertising trackers.
To be precise about where the line sits: we can see that the app was opened, which screen you looked at, how many days have passed since you installed it, whether an Apple Watch is paired, that a report or a data export was produced, and whether a purchase succeeded or failed. We deliberately do not send the things that would say something about your health. Not when you logged a hot flash, not how severe it was, not which therapy or dose you are on, not a symptom, not a score, not a note. Nothing read from Apple Health is transmitted, and nothing calculated from it either — not even whether there was enough of it to draw a chart.
You can export all of your data as CSV at any time from Settings, and delete everything by deleting the app. Because there is no server copy, deletion is immediate and complete.
Attune is intended for adults and is not directed at children under 13.
If this policy changes, the new version will be posted at this address with an updated effective date.
