About this app
Trustamp is the honest proof camera. It stamps every photo with a verified time and GPS location—then goes one step further than any timestamp or watermark camera: it can make the IMAGE ITSELF tamper-evident. Swap a face, remove an object, or run it through an AI editor, and the proof breaks. In the AI era, that's the part that matters.
WHY TRUSTAMP
✓ Three layers of proof, not two
Most timestamp cameras prove WHEN and WHERE a photo was taken. Trustamp also covers WHAT—the actual pixels. Turn on C2PA and the image is sealed into an open Content Credential at capture, so any later edit (AI face-swap, retouch, object removal) is detectable.
✓ Verify anywhere—not locked to us
Trustamp is built on the open C2PA / Content Credentials standard. Your recipient can check a photo in Adobe, Chrome, or any C2PA tool—no Trustamp account needed. There's also a public verify link for clients, insurers, and lawyers.
✓ Your data stays yours
Photos stay on your phone—the image itself is never uploaded unless YOU choose to. No forced cloud upload. No account required to start. No blockchain, no wallets.
✓ Flexible where it counts
- Refine the location detail (door/unit number) when GPS is off—while country, city, and street stay locked, and every change is transparently noted.
- Resize and reposition the watermark to fit your shot. (Most watermark cameras lock you to one fixed stamp.)
✓ Two modes, one app
Watermark mode: a fast, flexible stamp camera. Witnessed mode: server-witnessed and signed for proof that holds up. A user note is never disguised as a verified fact.
✓ Works offline
Capture with GPS and watermark even with no signal. Trustamp witnesses the timestamp automatically once you're back online.
✓ Free to download
No account, no sign-up—capture a watermarked photo and get a public verify link in your first minute.
