AFAIU (IANAL, much less an Estonian one) what’s usually considered ToS aren’t really necessary because you’re not entering a contract with lemm.ee that would bind anyone to anything – e.g. you’re not paying usage fees so there doesn’t need to be a stated policy on sitebans because if you went to court over a ban the court would ask “which services did you buy that they did not provide?”, then throw the case out.

That said this is the EU so there’s a privacy policy linked in the footer. It’s a GDPR requirement.
