What personal information do we collect?

Actively collected

This is data collected by direct input from you, with your consent, while using our app.

  • sex
  • age
  • height
  • weight
  • activity level

Passively collected

This is data collected from your device by third-party libraries used in our app to provide features such as targeted advertising and improved user experience. By using our app you agree and consent with the collection of this data.

  • device identification, such as the device advertising identifier

How do we use your personal information?

Actively collected

The actively collected information is strictly used to calculate your BMR (Basal Metabolic Rate) and TDEE (Total Daily Energy Expenditure). These calculations are made by our app locally on your device. Therefore, this information is not sent nor stored on other devices through the Internet or any other sort of network. The information may be locally stored in your device (e.g., in its local memory), but not on any other sort of longer-term storage on your device or on other devices.

Passively collected

This informaton is used by third-party services such as Google AdMob, to deliver targeted ads to you, and Google Analytics, to gather usage information to improve our app. These are the relevant links to the privacy policies and other useful information on potential third-party services being used by our app:

From “behavioral policies”, under “AdMob & AdSense” program policies:

Google may use the advertising ID from the device on which the ad is serving to generate interests and demographics (for example, ‘sports enthusiasts’). Interests, demographics, and other data may be used to serve better targeted ads to the user. Additionally, your app’s privacy policy may need to be updated to reflect the use of personalized advertising (formerly known as interest-based advertising) served via the Google Mobile Ads SDK. Please take a moment to review your app’s privacy policies and ensure that they are up-to-date. Because publisher pages and laws vary across countries, we’re unable to suggest specific privacy policy language.

To complement personalized advertising (formerly known as interest-based advertising), Ads Settings lets users view and edit their interests and demographics. Some users may choose to opt out of personalized ads.
