Field notes
The service separates webpage capture, local file sealing, and photo sharing into distinct applications while keeping one proof format. Its file workflow says selected files and folders remain on the Mac rather than being uploaded, while photo sharing produces a watermarked copy with a short identifier and browser verification link. Each completed package receives a cryptographic fingerprint and an OpenTimestamps record, so even a small alteration causes verification to fail.
