Ketora ("the App") is developed by Thomas Hermet. We are committed to protecting your privacy.
We do not operate servers. We do not collect, store, or have access to:
All data you enter in Ketora (fasting sessions, weight, hydration, mood, journal notes, settings) is stored locally on your device using Apple's SwiftData framework. If you enable iCloud, this data syncs across your devices through Apple's infrastructure. We never have access to this data.
Ketora may request access to Apple HealthKit to read and write body mass (weight), and to read step count and active energy burned. This data is only used locally within the app. HealthKit data is never sent to any server, shared with third parties, or used for advertising. You can revoke access at any time in iPhone Settings → Privacy & Security → Health → Ketora.
We use TelemetryDeck, a privacy-first analytics service, to collect anonymous usage statistics. TelemetryDeck does not collect personal data, does not use cookies, and is fully GDPR compliant. No personally identifiable information is ever transmitted. Learn more: https://telemetrydeck.com/privacy
In-app purchases and subscriptions are processed by Apple through the App Store. We use RevenueCat to manage subscription status. RevenueCat receives an anonymous app user ID and purchase receipts from Apple. No personal payment information is ever shared with us. See: https://www.revenuecat.com/privacy
Ketora is not directed at children under 13. We do not knowingly collect any information from children.
