NCompanionHow can we help?
Quick answers to the most common questions about NCompanion. Can't find yours? Write to us — a real person reads every message.
How do I log a meal?
Four ways, all from the plate on the Home screen: Point your camera at the food, Pick a photo from your library, Say it out loud, or Type it in a sentence. The Companion shows you what it understood — portions, calories, macros — and you confirm before anything is saved to your journal.
The analysis got something wrong — what do I do?
On the review screen, tap "Something not right?" and tell the Companion what to fix — "that was a small portion", "no butter" — and it updates its understanding before saving.
Where is my food history stored?
On your device. Your meal history lives locally in the app — meals are sent through our server to OpenAI for analysis; our server doesn't keep your food diary. If you turn on “Help improve recognition” (it is off unless you turn it on), our server keeps copies of some analysis results for 90 days, linked to a random key on your iPhone. See the Privacy Policy for details.
How do I delete my data?
Deleting the app deletes your food history, targets, and preferences — they are stored on your iPhone. There is no account to close. Deleting the app does not delete copies saved with “Help improve recognition”. If you turned it on, first go to You → Settings → Data & Privacy → “Delete saved copies”, or turn “Help improve recognition” off, which also deletes the copies saved from this iPhone. Keep the app until it shows the deletion as done. Otherwise the copies are deleted automatically within a day after their 90 days are up. See the Privacy Policy.
Can I get a copy of my saved copies?
Yes. Go to You → Settings → Data & Privacy → “Get a copy of saved copies”. The app makes a JSON file with the copies linked to the keys on this iPhone and opens the share sheet, so you choose where to save or send it. It works whether AI analysis and “Help improve recognition” are on or off, and it changes and deletes nothing. Copies saved from another device are not included. If you want a copy, get it before you delete your copies or turn either of these off. See section 13.2 of the Privacy Policy.
Does NCompanion work with Apple Health?
Yes — you can connect Apple Health so daily energy balance reflects your real activity. Health data is read on your device only and never reaches our servers.
Is the nutrition information medical advice?
No. NCompanion gives estimates to help you understand your eating patterns. It is not a medical device and doesn't replace advice from a doctor or dietitian — especially if you manage a medical condition.
