Cal Clark is a photo calorie tracker. Numbers are drafts you can edit. They are not medical advice.
You must be at least 16. Cal Clark is not for children.
You need an account (email, Apple, or Google) to save meals. You are responsible for access to that account.
Photo and text drafts are made with AI, then checked against published nutrition tables when we have a match. You can correct the result. We are not responsible for diet or health decisions made only from these drafts. See where the numbers come from.
Do not resell access, bypass the free-scan limit, or upload content unrelated to food in order to abuse the model.
Cal Clark is not medical advice and is not a dietitian. Talk to a clinician before a large change to how you eat or train.
You keep the photos and text you upload. You give us a licence to store them and send them so we can draft the log. The Cal Clark name and app remain ours.

Health-related data
Height, weight, goal, activity, and meal photos can reveal health status. Under GDPR this is special-category data. We use it only to set a calorie and protein budget and to keep your diary, after you choose to scan. We do not use it for ads. We do not diagnose, treat, or claim to be a medical device.
Cal Clark treats body metrics and meal logs as health-related data. The articles below are the published texts we follow. Official sites do not allow us to show their pages inside ours, so we quote the published wording here.

Not a medical device
Software is a medical device when the manufacturer assigns a medical purpose (diagnosis, prevention, monitoring, treatment). Cal Clark logs meals and drafts calories. It does not diagnose or treat. It is not a substitute for a clinician. It is not medical advice. We are not an FDA-cleared device.
