Your Data
Sixteen apps on this site keep something in your browser, and every one of them says so on its own page. This is the other half of that promise: what is actually there, what it weighs, and how to take it with you or get rid of it.
Nothing on this page talks to a server. It reads your browser's own storage, in your browser, and the export runs entirely on this device — there is no copy of any of it anywhere else unless you turned on passkey sync.
That also means deleting something here deletes the only copy. Export first if you are not sure.
