Sealed: Evidence Camera

Sealed turns your phone into a tamper-evident evidence camera. Every photo and video is signed on the device with a cryptographic seal (SHA-256 + ECDSA P-256) the instant you capture it — so later, anyone can check the file hasn't been edited since.

Built for the moments that become disputes: a car accident, rental or deposit damage, a delivery gone wrong, an insurance claim, a workplace incident. When it's your word against theirs, a sealed file shows the footage is the original.

WHY SEALED
• Tamper-evident by design — change a single pixel or second and the seal breaks, so the check fails.
• Verify anywhere, offline — share the file with a small verifier that runs in any browser. No account, no upload, and the Sealed app isn't needed to check it.
• On your device only — your photos and videos are never uploaded to us. No account, no cloud.
• The seal is burned into the footage — a Sealed mark plus a forensic overlay (time, GPS, heading, device) become part of the file, and the same fields are in the signed record. No one can remove the mark without breaking the seal; free and Pro produce the identical file.
• Quick access, one tap away — turn on a silent notification and reach Photo, Video and your files from the lock screen. Nothing runs on its own and no sensor is watching; you start every capture. While recording, the volume keys do the rest, so you can film without looking.

HOW IT WORKS
1. Record a sealed photo or video.
2. The file is hashed and signed on your phone at the moment of capture.
3. Export the file with its seal. Anyone can verify it — in Sealed, or with the included offline verifier in any browser.

SEALED PRO — one-time unlock, no subscription
• PDF evidence report with metadata, hashes and a chain-of-custody statement.
• Unlimited video length (the free tier seals clips up to 90 seconds).
• Case folders and tags to organise captures.
• Extra export formats (CSV, a self-verifying HTML file) and a notarized timestamp.
Pro removes ads. On the free tier, you watch one short rewarded ad per capture to share or export it, and it stays unlocked until you close the app.

HONEST ABOUT WHAT IT IS
Sealed proves integrity — that a file matches a signature made on this device at capture. It is tamper-evident, not a legal certification, and it does not by itself prove who held the phone. You are responsible for recording lawfully; in many places you must not record other people secretly — record openly.

Optional, off-by-default usage analytics never include your photos, videos, audio, GPS or seals.
