It’s late. These records stay on your phone.

What you eat and how your body changes are personal. Your saved records stay on your device, rather than being synchronized to our server.

Your saved records stay with you

  • Stored on your device — Your saved meal, exercise, body-metric, goal, favorite-food, report, and analysis records stay on your device.
  • AI helps with the analysis — When you request analysis, your text or photos are sent through our backend for processing after the consent disclosure. They do not become a server copy of your saved history.
  • Manual Google Drive backup — Back up to the private app-data area of your own Google Drive account, then restore when you change devices or reinstall.

Where is my data stored?

Your saved records are stored on your device. When you request AI analysis or a report, the data needed to complete that request is sent to our backend and third parties for processing; see the Privacy Policy for details.

How do I keep my records when changing phones?

Manually create a Google Drive backup in the app first, then sign in to the same Google account on the new device and manually restore it. This is not automatic sync.

How much history do reports need?

A weekly report needs at least 4 days of records, and a monthly report needs at least 14 days. The app shows that data is still accumulating until the period ends.
