Aurora should actually say in the description of the installation/update screen if the app requires google play services or any telemetry at all (or for that matter, google sign in).
No, Play Store does not require Play Services integration, nor does it mandate any trackers.
In practice though, most use Play Services for lush notifications, and there are a LOT of apps with at least Google Crashlytics, Google Firebase Analytics, and Google Admob trackers. Check out Exodus for tracker reports. Or use the Tracker Controller app. Just note that some trackers are pretty benign, or even a security feature, like Sentry.
FWIW, you can install the entire proton suite with Obtainium. For whatever reason though, 1password exclusively distributes through the Google play store, but AFAIK that doesn't make the app itself any less private.
Can you? I just looked into this this other day and I didn't see proton calendar on github, it was just an apk you could download on protons site
Looking at Proton calendar, it seems I just put the website into Obtainium, I think there's a monorepo somewhere, but I couldn't find it.
Huh, okay, I thought it had to be a github repo. I'll look into that. Thx.
Why not just use Proton Pass?
Because you should have your email, password manager, and authenticator be 3 different services. Otherwise there is 1 point of failure.
My understanding is the password manager is fully local to the device. Its only compromise-able if you back it up to their cloud. Same goes for the authenticator.
Offline mode is available for free on the mobile app, but not desktop. Doesn't work offline for browser extension at all, which is how auto fill works on desktop, which is much more useful. And offline mode for Proton just means you can view the passwords you already created, not create more.
There are true offline local password managers but as long as the cloud sync is encrypted, I see no reason to avoid using it and miss out on half the functionality. Auth is more debatable but I've found uses for cloud hosted Auth too.
Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
