Privacy settings
Open More and look under Privacy. Anonymous usage stats and Send crash reports each have a switch, and both are on unless you turn them off.
In the free app, where Google's consent message applies, a Privacy choices row in More lets you change your ad choices. On iPhone and iPad, the tracking permission is in your device's Settings, under Privacy & Security, then Tracking.
The privacy policy explains what each app sends and to whom.
Common questions
How do I convert Calories to kilojoules?
Type the number in the Calories box. The kilojoules box fills in as you type. One Calorie is 4.184 kilojoules. Tap the kilojoules box to convert from kilojoules instead.
Is the walking time exact?
No. Without your weight the walking guide shows a range for a reference adult. Add your weight in your profile and it gives one estimate. Treat both as a guide.
How do I switch between the calculators?
Convert, Portion, Exercise to energy and BMI are all behind the radial control on the Convert button.
What does Pro include?
29 more exercises, the deeper body report and no ads. It is a one-off purchase, not a subscription.
I bought Pro before. How do I get it back?
In the free app, open More. In the Your plan box at the top, tap Restore purchases. The app asks the App Store or Google Play which purchases belong to your store account, so use the same Apple ID or Google account you bought with. The store may ask you to sign in. Refresh status checks again without asking you to sign in. If you have the separate Pro app, there is nothing to restore: Pro is included, and you can download the app again from the store with the account you bought it with.
Which food comparisons are used?
Everyday single-serving estimates, not individual nutrition labels. Recipes and portions vary.
