Use cases

Use case

Anchor move-in and move-out condition.

Condition disputes often turn on whether a file still matches what was captured. FactLockCam seals the original bytes and signed metadata so a recipient can inspect them later without creating an account.

  • Same angles, both dates
  • No recipient account
  • Nothing uploaded

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 a .flcproof file. Share it out of band and keep the password separate. The other party opens factlockcam.com/open, selects the file, and inspects it in the browser. Nothing is uploaded to FactLockCam.

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.

Next step

Two dates. One comparable record.

Capture the same rooms at move-in and move-out so both parties can compare like with like.
