About this app

JotNotes is an encrypted notebook with multiple separate spaces. Type a passphrase and it opens the notes space that belongs to that passphrase. Type a different one and you get a completely separate space — neither can see the other's contents. • No account, no sign-in, no network • Everything is stored AES-encrypted on your own device • There is no "wrong password" state — any phrase opens its own space • No list of spaces, and no count of how many you have Because a space you cannot open looks exactly like a space that was never created, you can hand your phone to someone and just open it with the phrase you use every day. PRIVACY BY DESIGN • Note content never shows up in the app switcher preview • Anything you copied is cleared from the clipboard when you lock or leave the app ALSO • Drag to reorder notes, one-tap copy • Fully offline. No data collection, no accounts, no ads, no tracking Please note: if you forget a passphrase, that space cannot be opened again — there is deliberately no recovery. Deleting the app or resetting your device erases the contents of every space.
