In Pokémon GO tap your avatar, screenshot the profile page (the one with your name and LEVEL) and pick it here. Profile screenshots mixed into a normal import are recognised too.
Backup and Restore move your scans between browsers without a server. With sync connected (cloud button) every device already shares the same data.
Screenshots are opened on your phone and never uploaded whole: only small crops (numbers, a name, a few lines) go to the PokeScan server to be read as text, and it keeps nothing. Scans, roster and settings live in this browser's storage; with an account they also sync to your other devices, and the Pro AI features send what you submit to the server.
