Measure and support our marketing
- Campaign Data and Referral Data: On Android, this helps Firefox Focus understand the effectiveness of our marketing campaigns. Focus may use “Referral Data” such as the website domain or advertising campaign that referred you to download and install Focus. This data is kept by Adjust, our analytics vendor, and provided when you start Focus, and also includes a Google advertising ID, timestamp, country, locale, operating system, and app version. Mozilla does not receive this data for Klar. Read the documentation.
- Search suggestions: If enabled, Firefox Focus sends search queries to your search provider to help you discover common phrases other people have searched for and improve your search experience. These data will not be sent if your selected search provider does not support search suggestions.
