A password you draw, not type
Notes, files, photos and two-factor codes, behind a picture password. Letters and numbers float over your own photograph. You drag them until your character lands on your spot. Someone standing over your shoulder sees a fingertip cross a picture.

How it opens
After that, opening the vault is one drag per character. The grid is dealt again from scratch on every attempt, so no two unlocks look alike, and watching one teaches nothing about the next.
One photograph, and every secret lives on it. Busy beats beautiful: a crowd or a skyline gives you landmarks only you would think of, where one big subject has everybody picking the same eye.
From sixteen that cannot be misread: the digits, and A, C, E, H, K, N. B against 8 and O against 0 are gone, because a character you misread over a moving photo is a password you cannot enter.
Drag the whole grid until your character sits on your landmark, then let go. Every one of them on the grid is the same character, so the one you are aiming with is not the one anybody can pick out.
What it holds
Notes, files, photographs, logins and two-factor codes, in folders you name and colour. Codes tick over on the home screen. Logins fill on the page you are looking at, and the extension asks for no standing access to any website to do it: clicking the toolbar button is what lets it reach that one page, until you leave.
Nothing out of the vault is uploaded, and there is nothing to sign in to. The vault is a file on your own machine. The free Android app carries an ad, which is the one thing on this page that talks to anybody; it is two paragraphs down, and it is never given anything from in here.


Backups
A backup holds every folder, including the ones you were not going to open today, and its size says what you keep rather than how many secrets you keep it in.
Seventeen written-down words open it anywhere, with no account and no passkey. A passkey and your picture password open it too, both together and never either alone, so a stolen phone with a known PIN is not a way round the drag.

Said plainly
Three apps, one mechanism
The phones run one implementation of the scheme, the archive format and the throttle, so nothing about how a vault opens exists twice. A browser cannot run that code, so the extension carries its own, and the two are held against each other by fixtures written from one and asserted by the other. A backup made on either opens on both.
The vault in the side panel, filling logins on the page you are already looking at.
Folders, notes, files and codes, with the key held in the Keystore and in StrongBox where the phone has it.
The same mechanism again, with the key held by the Secure Enclave.
