Baseline stores what you log so it can coach you. Your meal photos and your messages to the coach are sent to OpenAI to produce estimates and replies. Nothing is sold, nothing is used for advertising, and you can export or delete everything from inside the app at any time.
Meal analysis and the coach are built on OpenAImodels. When you photograph a meal or send the coach a message, that photo or text — along with the relevant parts of your targets and recent logs, so the answer is about you — is sent to OpenAI's API to generate the estimate or reply.
OpenAI processes it on Baseline's behalf and, under their API terms, does not use it to train their models. Baseline does not train any model on your data either. If you would rather nothing left the device, the AI features are the ones to avoid — manual logging works without them.
Read-only, and only what you allow. Baseline never writes to Apple Health or Health Connect. Health data read from them is stored with the rest of your account so the coach can use it, and it is never used for advertising or shared for anyone else's marketing.
That is the whole list. There are no advertising networks, no data brokers, and no third-party trackers.
Export— Profile → Export my data gives you a single JSON file of everything, including your photos' locations.
Delete — Profile → Delete account removes the account itself along with every meal, photo, scan, recipe and conversation. It is immediate, it cascades, and there is no recovery and no grace period.
Baseline is a consumer wellness product for adults 18 and over. It is not a medical device and does not diagnose, treat or prevent anything. Calorie and macro figures from a photo are estimates, and the app says so wherever it shows one. If something about your health worries you, talk to a clinician.
If this policy changes in a way that affects what happens to your data, the app will say so rather than quietly updating the date. Questions: hello@baseline.day.
