What Tab is
Tab estimates what is in your food and keeps a record of it. It is a tracking tool, not a medical device and not a clinician. Nothing in it is medical advice, and it should not be used to manage a diagnosed condition without someone qualified involved.
Accuracy
Nutrition comes from USDA FoodData Central, Open Food Facts, and the labels you photograph. Source licenses and the open food catalogue are listed under Data sources. Portion sizes are estimated from a photograph, and estimates are wrong sometimes — that is the nature of reading a meal from an image. Check anything that matters, and correct anything that looks off; the app is built to be corrected.
Your account
You need to be 18 or over. Keep your password to yourself. Do not upload anything you do not have the right to upload.
Optional scan improvement
You can separately choose to let Tab retain a small random sample of future meal scan photos for accuracy review, as described in the Privacy Policy. You can withdraw that choice in Settings at any time; declining does not stop normal meal scanning.
Subscriptions
Tab Pro is sold through the App Store and Google Play and billed by them. It renews until you cancel, and you cancel in the store's own subscription settings — we cannot do it for you. A free trial converts to a paid period unless it is cancelled before it ends. Refunds are the store's decision under their policies.
Fair use
Do not attempt to break, scrape or overload the service, and do not resell access to it.
Ending it
You can delete your account at any time from Settings. We may close an account that is being used to abuse the service, and we will say why.
Liability
Tab is provided as it is. To the extent the law allows, we are not liable for decisions made on the basis of an estimate the app produced. Where the law does not allow that limit — and in some places it does not — this clause does not apply to you.
