Look people have a very “all or nothing” approach that I myself disagree with. They want true privacy? Buy a dumb phone, never go online, and disconnect the landline.
I hear you, I also started out with just proton, but I’ve gone deeper slowly — I do have Pihole, I don’t use Google services, but these are not things you need to do to get more privacy.
I think from your comments it seems like you’re just worried Google will know your email address, and that’s… not a big deal?.You probably will give out that email address anyway, so they’ll find it eventually.
The contents of the emails, which is where important data really is, are encrypted in proton. Google shouldn’t be able to read your screen contents, but who knows for sure. So you should be fine for now, don’t worry about logging in the phone.
I’ve noticed that my app takes a while to deploy, so I just wait for it to finish and eventually the probe works. 10-ish minutes usually works.
