On privascore.org you can find alternative apps and services for numerous topics. For example, use browsers such as the DuckDuckGo browser, which do not collect any data about you. The εxodus project also provides you with information about the trackers and permissions used by many apps. For example, map apps such as Organic Maps or Magic Earth do not use trackers at all and are therefore a good alternative to Google Maps.
In the alternative app store F-Droid, you can also see which apps may contain unwanted features such as trackers.
