"We collect 'Advertising ID', which is a unique, user-resettable identification number for advertising associated with a device (e.g., iOS uses the Identifier for Advertising (or 'IDFA') and Android uses Google Advertising ID). Location data and other information about devices used to access and interact with the Websites or App."
The app collects advertising IDs, device IDs, device type and settings, browser details, and location data — much of which serves advertising rather than core diet-tracking functionality.
