Applies to all modules

• No user account. Kairos does not require registration, an email address or signing in with me. I don't know who uses the app.
• Local only. All content lives in a local SQLite database inside your device's private app container; particularly sensitive fields are additionally encrypted with AES-256-GCM, with the key in the keychain (iOS Keychain or Android Keystore). Deleting the app removes this data.
• No server of mine. Kairos has no server of its own. The only network connection is purchasing and verifying the subscription via StoreKit 2 (Apple) or Google Play Billing (expo-iap) — Apple's/Google's own privacy terms apply there as well.
• Sharing only by you. Exports, backups and reports (PDF/ZIP/CSV) are only ever shared through the system share sheet, when you trigger it yourself.
• Subscription. Kairos is a subscription (€3.99/month, €34.99/year) with a free basic tier; purchase and management run entirely through Apple/Google — I never see any payment details.

Legal basis

Local processing on your device: Art. 6(1)(b) GDPR (performance of the contract/use of the app) or legitimate interest (Art. 6(1)(f) GDPR). Any voluntary sharing (export, share sheet) happens at your own initiative.

Your rights

Since all content lives exclusively on your device, you can view, change, export or delete it yourself at any time (app settings or uninstalling). For questions about this processing, reach me at christian@tonke.de.
