What to document
- Each room, fixture, appliance, and existing wear at move-in
- The same angles at move-out so the two records can be compared
- Keys, meters, or inventory items that later become points of dispute
Capture and seal
Use Picture or Video from the FactLockCam hub. Each capture gets a SHA-256 fingerprint and a signed canonical manifest. Keep the encrypted items in your archive until you need to share them.
Context that does not rewrite the file
Add a title such as "Unit 4B kitchen — move-in" and a short description. That context is for the recipient. It is not a substitute for the sealed media or the signed record.
Share a package they can open themselves
Send Proof produces one .flcproof file, and the app makes the unlock key. Neither of you types a password. For a small proof, the other party opens the link, chooses the file, and checks it in their browser. Nothing is uploaded to FactLockCam. A walk-through video can be large (25 MiB or more). A large proof opens in the free FactLockFile desktop Viewer, coming for Mac, Windows and Linux once each version is tested. Its unlock key travels as a note beside the file.
What verification shows
A passing verification shows that the inspected file matches the recorded fingerprint and that the signed metadata has not changed. It verifies the exact file and signed record; the full scope is on the threat model page.
