Memotack keeps notes and checklists where you'll actually see them — stuck to your Android home screen, not buried in an app you forget to open.
Notes are written and stored on your phone first. If you never sign in, nothing leaves the device. Sign in only if you want the same notes on more than one phone.
Synced notes are scoped to your account by database-level rules, so one account cannot read another's notes — not through the app, and not by any other route. The privacy policy spells out exactly what is stored.
