The five steps

  1. 1

    Capture

    Take the photo on a supported Android device with hardware-backed keys.

  2. 2

    Sign

    The original JPEG is hashed and signed in Keystore. That is not a cloud round-trip.

  3. 3

    Organize

    Leave it standalone or attach notes, location, a task, a project, or a reference.

  4. 4

    Share

    Send the original file. Chat previews are not the original.

  5. 5

    Prove

    A recipient uploads that original to the public verifier and reads valid, limited, or not valid.
