In the app, the photo is taken like with any camera.
The stamp is a statement by whoever issued it. What gets verified is where the file came from and the moment.
Proof of work
The photo that ends the argument on WhatsApp.
Time, date and address on the image, so the group can see them. And the original file, checkable if someone doubts it.
Strip enlarged here: in the real photo, the eye cannot see it.

Matches
Matches is not the same as intact: it is the same scene, within the hash tolerance.
The job, in the photo, in the group
How it works
Address pulled on the spot, adjustable with one tap before you save. The group gets the photo; checking the file uses the original.
Free to try. Pro for the daily run.
Twelve photos on the account, for life. Pro lifts the cap and follows you on every device you sign into.
Free
12 photos, no card
Create an account, stamp, export. Enough to run the whole loop — including verification.
Lymark Pro

The amount is for the country you browse from. Cancel anytime: Pro lasts until the paid period ends.
What Lymark does — and does not
On the device
The photo never uploads
The server keeps email and plan. Never the image, never your location. The account exists so the subscription can.
The check
Intact or it doesn’t match. That’s all.
Intact, no seal, or mismatch. Whoever checks sees that. It happens on this device.
Honest limit
Not a notary
Time and address on the stamp are the photographer's declaration. The file can be checked. It does not stand in for public faith.
