You control your data in Renewise. Here is exactly how, with the in-app paths.
Notifications
Turn reminders on or off in the app's Notifications settings, and control system delivery in iOS Settings → Notifications → Renewise.
iCloud Sync
Turn syncing on or off in Settings → iCloud Sync (Full version). It is off by default and uses your private iCloud.
Apple Watch sync
The watch mirrors your iPhone automatically over WatchConnectivity. Open the iPhone app nearby to send the latest snapshot.
Show Amounts
Hide all amounts on the watch (and widgets) with the Show Amounts toggle in the watch settings.
Photos access
Renewise uses the system photo picker for screenshot import, so it sees only the image you pick — there is no full photo-library permission to manage.
Voice and Speech
Quick Add uses watchOS system dictation; Renewise uses no microphone permission. Manage dictation in iOS/watchOS settings.
Screenshot import
Optional and Full-version only. The image is read on-device and not stored.
Face ID lock
Turn the optional app lock on or off in Settings → Security & Privacy.
Exported files
If you exported a backup, that file is wherever you saved it. Delete it like any other file.
Delete one subscription
Swipe or delete a subscription in the list to remove it and its reminders.
Delete local data
Settings → Security & Privacy → Delete Subscription Data removes everything on the device.
Delete local and iCloud data
The same action clears the iCloud copy when iCloud is reachable. Delete synced data before uninstalling if you want the iCloud copy gone.
