I'm starting work on the "Popularity Contest" idea for @fdroidorg that will provide #anonymous statistics on app usage as part of @guardianproject's #CleanInsights project, follow progress at https://gitlab.com/fdroid/fdroidclient/-/issues/396
@davidak This is part of #CleanInsights project, we're trying to publish as much as we can on the topic http://cleaninsights.org/, a lot of it is more about the approach rather than a library since there are so many data sources and things to track
