Sickness Journal is a personal health journal built to work entirely on your device. This page explains exactly what that means.
None. Sickness Journal has no account system, no sign-in, and no backend server. The episodes, progress entries, and medications you log are stored only in the app's local storage on your device and, if you use iCloud, are synced via Apple's own iCloud/CloudKit sync between your own devices — DFB Software never receives or has access to this data.
Everything you record — symptoms, severity, notes, and medications — stays on your device (and your own iCloud account, if enabled). DFB Software has no server to send this information to and never sees it.
If you enable reminders in Settings, Sickness Journal schedules local notifications on your device using Apple's UserNotifications framework. These reminders are generated and delivered entirely on-device — no reminder content or scheduling data is sent anywhere.
Sickness Journal contains no third-party advertising SDKs, analytics SDKs, or tracking of any kind. We don't use the App Tracking Transparency framework because we don't track you.
Sickness Journal offers an optional one-time premium unlock and optional tips, processed entirely by Apple through StoreKit. Payment details are handled by Apple under Apple's own privacy policy — DFB Software never sees or stores your payment information. Premium does not gate any feature — it exists purely as an optional way to support development.
Questions about this policy or your data can be sent to support@dfbsoftware.dk.
