These apps do not collect, store, or share any personal data. No account, no sign-up, no advertising, no analytics, and no tracking.
Everything you create in these apps — habits and check-offs (Streak), time entries (Tempo), transactions (Coinly), reading preferences (Inkwell) — is stored only on your own device and is never uploaded anywhere. Removing an app deletes its data.
Lumina displays the photos already on your device. It only reads them to show your gallery on-screen; photos are never uploaded, copied off the device, or shared.
Only Lumina requests a permission (access to your photos), used solely to display your gallery. The other apps request no sensitive permissions.
These apps are safe for all ages and collect no data from anyone.
