Shelter + Shizuku + App Ops
Shelter will put it in a work profile.
Shizuku and App Ops work together to give you more control over app permissions. You can restrict a lot this way.
Granted, that won’t stop the normal data collection via your IP address that occurs as a result of browsing their content.
It’s unclear to me how these torrents are used. If individual books are not downloaded from them, is this only to make it possible to create similar sites in the future, in case this one is taken down?
