Calories and macros from a photo of your plate
Photograph the meal, correct the weights the model guessed wrong, and the day adds up. Your diary travels to the server encrypted — the key stays on your phone.
What it actually does
One photo, one estimate. The model names the dishes and guesses the portion weights; you fix the guesses it got wrong, because it will get some wrong. The result is a normal food diary with calories and macros per meal and per day.
What stays on your phone
The diary — entries, weights and the small photo previews — lives in your browser's storage on the device, and a copy travels to the server sealed: the key stays with you, and we cannot read the entries either. A second device opens the diary with the recovery code — lose the code along with the phone and there is nothing left to bring it back with. A backup is a file you export yourself, and it stays with you.
The photograph is the exception, and it is worth being precise about. With your own key it goes from your device straight to the platform whose key you entered, bypassing our server; there are nine such addresses, named one by one in the privacy policy. The platform's terms apply from there: at Google, for one, the free key tier reserves the right to use what you send to improve its products, and the paid tier does not. With the Snapfork key it goes through our server and onward through OpenRouter to the model provider — not stored here, and we tell the platform not to route through providers that retain what is sent. The route is yours to choose, and by default it runs your key first and our server only after yours has failed. A checkbox in settings turns that off — and we would rather you knew before you signed up.
Who can get in
Anyone. Sign in with a code sent to your email, with Google or with Apple — there is no invitation to wait for and no queue to join. Your own platform API key is optional: two photos a day are recognised on the Snapfork key for free, and your own key removes both the daily cap and the extra hops on the photo's way out. What those hops are is written above, and we are not going to pretend they are not there.
