These are just a couple apps that I’ve found in the last year that I didn’t know about and wanted to share with the community. Be advised- Lumen asks you to install a root TLS Cert and says that it uses this to monitor the types of connections other apps are making. I’m not really qualified to say if that’s truly the case or not(but I installed it because I wanted to know if my other apps were making encrypted connections or not), I know that is probably a deal breaker for some which is why I’m telling you upfront. Also, only exodus privacy is open source and available through f droid. You can download Lumen directly from their site or the playstore. I hope this helps anyone who is curious about what sdks, advertising, analytics, and crash reporting is onboard the apps that you download and also what connections those apps are making in the background. I had a third one called addon detector I wanted to link to, but it only lets me post 2 links. You can search for it in the playstore.
