Small tools that work in your hands.

Passwords, keys, sealed notes, the reading a site takes from your browser. Most of them run entirely in the tab — where a tool needs our server, it says so in its own line.

Each tool says what leaves the page

Generation, encryption, key pairs and the fingerprint report are computed in the tab and stay there. Two tools need a server of ours, and both name it in their own footer.

Where data is missing, the page says so plainly.

The tools end where the contour begins

A password fits in a field, a note fits in a block. Mail, files, knowledge and AI need a place of their own — on hardware you control, with keys that stay yours.
