Last updated: June 9, 2026. Onset is a private caffeine timing tracker for iPhone. This policy explains what Onset stores, what it does not collect, and how to contact us with privacy questions.
Onset v1 is local-only. It does not require an account, does not sync your caffeine history to a cloud service, does not use analytics, and does not track you across apps or websites.
Onset stores the caffeine entries you create, including source, amount, time, and optional notes. This history stays on your device unless you choose to export it.
Onset also stores app preferences locally, such as appearance, caffeine assumptions, bedtime assumptions, and onboarding completion state. These settings use local device storage such as UserDefaults.
Onset v1 does not collect account or login information, cloud-synced caffeine history, analytics events, advertising identifiers, cross-app or cross-website tracking data, or subscription/in-app purchase data.
Onset does not sell or share personal data.
Onset includes local export tools so you can export your caffeine history. To delete Onset data, delete entries in the app where available or remove the app from your iPhone. Removing the app deletes its local app data according to iOS behavior.
Onset shows caffeine estimates for awareness only. Caffeine timing and half-life can vary by person. Onset is not a medical device and does not provide medical advice, diagnosis, or treatment.
Onset is not intended for children under 13. Onset does not knowingly collect personal information from children.
This policy may be updated as Onset changes. If future versions add accounts, cloud sync, analytics, subscriptions, or other data processing, this policy will be updated before those changes are released.
