Prodrome

Privacy Policy

Last updated June 11, 2026

What we collect

Nothing. Prodrome does not collect, store, or transmit any personal data to the developer or to any third party. There are no accounts, no developer-operated servers, no analytics, no tracking, and no crash-reporting frameworks.

Health data

With your permission, Prodrome reads data from Apple HealthKit (sleep, heart-rate variability, resting heart rate, respiratory rate, activity, menstrual cycle, wrist temperature). This data is processed entirely on your device. It is never sent to the developer or any third party, and is never used for advertising, marketing, or sold to data brokers. You can revoke access at any time in Settings → Health.

Location & weather

With your permission, Prodrome uses your coarse location solely to request local weather conditions (barometric pressure) from Apple Weather. The request goes directly from your device to Apple; the developer never receives your location.

iCloud sync

Your records sync through your own private iCloud database (Apple CloudKit), tied to your Apple ID. This is Apple infrastructure under your account — the developer has no access to it. If you sign out of iCloud, the app keeps working with on-device storage only.

Export

You can export all of your data as a single file at any time. That file is created on your device and goes only where you choose to save or share it.
