I use KOReader both on Linux and Android, and I love it! I used Calibre’s own reader for epub files earlier, but have since used a bit of time getting to know KOReader and its features better, and it suits my needs very well.

You need to be unplugged for 12 consecutive months for Proton to delete your account because of inactivity though, which seems fair for free tier accounts. A simple login is enough to prevent this, you do not need to send an email or whatever, simply log in once a year. You also get reminders sent to your recovery email before this happens. Data storage for inactive free tier accounts isn’t free for Proton.
