Providers usually say they do not keep logs but it depends on the privacy statement and their long and confusing policies, I recommend always use a paid service that has more than 3 hops per connection and a flow in the connectivity.
I have not used it, but I can tell you that their website is down and always remember to be careful with the topic of the 0logs many times it is not true because in their policies they talk about the sale of information to third parties.
