FactLockCam: Evidence Camera

FactLockCam is an on-device evidence camera. Capture a photo or video, and the app creates a verifiable file fingerprint and signed capture record you can share later. Capture a photo or video in FactLockCam. The app computes its SHA-256 fingerprint, places it in a signed capture manifest, and anchors the manifest hash in a public Polygon transaction. If someone later changes the file, the altered copy produces different bytes and fails the original fingerprint check. Send a password-protected `.flcproof` package to an adjuster, landlord, customer, journalist, or other recipient. They can inspect it locally at factlockcam.com/open without uploading the package or installing the app. Verifies the exact file and signed record—not the physical truth of the scene. Each capture record discloses its device_key_class; hardware attestation is not claimed. Anchor the original before the story changes.
