Document involved? Drop it here — optional.
The file stays on your computer. Its fingerprint is computed right here, in your browser. Nothing uploads.
Your device reads the file and reduces it to a digital fingerprint. The same file produces the same fingerprint; change the file and the fingerprint changes.
The file never leaves your device. A fingerprint is not a copy and cannot be reversed to recover the document. It contains none of the document’s contents.
When you attest, two independent timestamps fix when. The fingerprint fixes which exact file. Anyone can later verify both — without trusting us, and without showing us the file.
The file. Your judgment. Bound to the same attestation.
