I have been slowly degoogling my life by reducing my use of Google apps and switching to FOSS alternatives. I recently created a Proton account and tried to keep it completely isolated from my default Google account so as to not let it know what my Proton mail identity is. I have finished my transition in my desktop to the best of my ability and am planning to start the same with my mobile. The only thing I have done in my Android phone related to Proton is having downloaded ProtonVPN and signed into my account within the app. However I fear by downloading ProtonMail and signing into it, my Android phone would identify the email account, which could make this entire transition useless. Is there a way to avoid this situation or has the damage already been done. What does Google know about my Proton account, if at all?
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 sincerely thank you for understanding my situation and giving me actually useful advice.
