for example your claim of “no logging” is at best partially false, since their own privacy policy clearly states that IP addresses are at least temporarily collected, always and without exceptions.
who is the owner and how the company is funded is not important here, they are selling products and advertising them through claims that need verification.


more private than what? which features are you looking for?
there are potentially many apps for it, but the question needs to be more specific.
