Before I yap, I recommend ASAP to determine your threat modeling and how much convenience you want to sacrifice for your OpSec. Using Google and YouTube and other corporations is valid, and using only Tor & I2P connecting to privacy friendly services is valid too. Use email aliasing, addy & simplelogin are good but duck.com works also. It’s drastically better for your OpSec (operations security), and in case of a data breach, it’s also best to have that random email alias that forwards to your Proton. I also like Tutamail, no IMAP/SMTP because of the encryption but it’s really nice and the guys behind it are cool. Using ProtonVPN/RiseupVPN for speed is good, but Orbot and Tor is best for your OpSec. Also, don’t forget Odysee! If your favorite YouTubers are on Odysee, which mine are, use it! FreeTube is cool, too.
I HIGHLY recommend privacyguides.org for getting into degoogling and improving your privacy and OpSec, and good luck! :3
