03 / For you

Read it first.Sign when you are ready.

When an item asks for your signature, the full document stays in front of you. Read it, complete the marked places, and confirm with your passkey. The signed copy then stays beside the original.

  • Sealed your copy, and anyone can check it
  1. Read

    The whole thing, before anything is signed

    The document is in front of you, not summarised, not a link to a preview. The places you have to fill in are marked where the sender put them, so you are not hunting for the line.

  2. Sign

    It is you signing, and that is the part that matters later

    You confirm with the passkey on your own phone, unlocked by your face or your fingerprint. There is no signature image to copy, no password anybody could have used, and nothing that works without the device in your hand.

  3. Keep

    The copy is yours, and it proves itself

    What comes back is a sealed PDF you keep, send on, or hand to a court. Whoever you give it to can check it themselves, without an account and without asking you or us for anything.

A scanned signature only proves that somebody had a scanner.

What you sign
Fields placed in the document by the sender, where they need them.
What binds it to you
Your passkey, signing the fingerprint of that exact document and no other.
Whether it counts
An advanced electronic signature with a trusted timestamp, admissible under the Evidence Act.

The detail

What am I actually doing when I confirm with my face?
Your phone is unlocking a key that only it holds, and that key signs a value built from this document's fingerprint. Your face is never sent anywhere: it stays on the device and only tells the device it is you. What travels is the signature, which is why nobody can produce one for you by knowing something about you.
What stops somebody reusing my signature on another document?
The thing you signed includes the fingerprint of this document and your place on it. Move it to another document and the value no longer matches, so the signature does not transfer. That is the difference between this and an image of your name, which transfers to anything.
What if I do not have a passkey yet?
You can still sign, and the record says plainly that this one rests on our attestation rather than on your own key. What cannot happen is the quiet downgrade: if you have a passkey and it fails, the signature is refused rather than recorded at the weaker strength without telling you.
What do I get back?
A sealed PDF, yours to keep, send on, print, or hand to a court. It carries the timestamp from an independent time authority and enough validation material inside the file to still be checkable in ten years, when the certificates behind it have expired.
Do I have to sign the whole thing at once?
No. The document is in front of you at full size, the places you have to fill in are marked where the sender put them, and nothing is signed until you say so. Reading it is the point; the marks are the last step.
Can somebody I share my Keepable with sign for me?
No. Somebody you have let in can read everything, including this, and cannot sign, agree, decline or submit anything. Those acts are bound to your own passkey, so a delegated signature would be a forged one.

The limit

Signing here does not mean you agreed to something you did not read, and it does not settle a dispute about what the document says. What it settles is whether it was you, and whether the wording moved afterwards. If you do not want to sign, you do not have to, and nothing is ever signed on your behalf.
