It might be a good idea to setup a sudo anonymous account if you find that important.

Install tor browser

Use this to setup a “privacy focused” second email account

Use this account to create a user account https://unite.openworlds.info/explore/repos with an interesting nickname which you do not use anywhere else.

Always login from the tor browser.

Add the email site to /etc/hosts redirected to localhost on your laptop to make sure you only login with tor.
