Terms of Service

Last updated July 6, 2026

These terms are written in plain language on purpose. By using this website or the TwentyGrams app, you agree to the following.

Not a medical device

TwentyGrams is a food-logging tool. It does not diagnose, treat, or monitor any medical condition, and it does not interpret blood-sugar readings. It is not a substitute for advice from a doctor, dietitian, or other qualified professional — always check with them before making decisions about your health.

Food data

Nutrition numbers come from the USDA FoodData Central database and Open Food Facts. We work hard to keep this data accurate, but no database is perfect — always use your own judgment, especially for medically significant decisions.

Free logging, forever

The core logging loop — voice/text logging, search, barcode, your history — is free, with no time limit and no feature removed to push an upgrade, and nothing that is free today will move behind the paywall. An optional Premium tier (glucose overlay, metabolic logbook, daily coaching, trend insights, doctor export) launches together with the app; it is not available yet, and this website has no purchase path today.

The waitlist

Joining the waitlist only signs you up for launch and confirmation emails from Kit (ConvertKit), our email provider. You can unsubscribe at any time. See ourPrivacy Policy for details on how that data is handled.

Changes

We may update these terms as TwentyGrams grows. Meaningful changes will be reflected by the "last updated" date above.
