Lymark stamps the photo the moment it is taken.
The stamp is the issuer's statement. What gets verified is the file's origin and the moment.
Verify authenticity
Drop or choose a photo exported by Lymark — JPEG, MP4 or the companion .lym — and see instantly whether it is exactly as it left the app — and who issued it, when.
The seal confirms the file integrity and the issuance time (iat), by the server. The capture time, on the stamp and in the EXIF, is declared by the device.
Drop the photo, the video or the .lym file. You can drop both together.
The file never leaves this device. It is read in your browser. Only the fields read go to the server — never the image.
