I'm sure they'd be surveiling us regardless. I'll keep using my VPN.

I'm not sure if you've heard of Paralino, but I've been using it and I've been happy with it so far.

Unfortunately, it's not open-source, but it's more privacy-oriented, end-to-end encrypted, can be installed with an APK, and subscriptions can be bought outside of the app stores.

It's not exactly the perfect solution that you're asking for, but it's a huge step up from Life360.
