User Guide
FactLockCam is a private, tamper-evident media archive with verified Digital DNA at capture—not a messaging app. This guide explains how to seal media with verified Digital DNA, browse your local-first encrypted archive, and deliver tamper-proof proof to recipients. Procedural and evidentiary details for professionals are in our Terms of Service.
Capture & Seal
- Open Picture or Video from the hub.
- Frame your subject and tap the mechanical shutter control.
- FactLockCam seals the capture on-device—SHA-256 fingerprint, AES-GCM encryption, and a transactional journal that records prepare/commit integrity (your Digital DNA).
- When online, integrity metadata can sync to the public ledger; offline captures stay marked pending sync until retried.
Archive & Inspect
The Archive tile lists sealed items in grid or chronology view. Tap an item to inspect metadata, view a thumbnail, decrypt the full asset on demand, export a tamper-proof certificate, or Send Proof.
Send Proof (Courier)
- Choose Send Proof from the asset inspector.
- Set a one-time password and optional certificate title.
- Share the generated PDF and courier URL through the iOS share sheet (Messages, Mail, AirDrop, etc.).
- Communicate the password to the recipient out-of-band.
Recipients open the link in a browser, enter the password, and decrypt locally. Plaintext never transits FactLockCam servers after unlock—we cannot access your unencrypted files.
Account & Burn
Account deletion (Burn Account) requires double confirmation and invokes
perform_full_burn to purge cloud-linked profile data. Local encrypted files are
wiped from the device as part of the burn flow.
