This kind of service appears interesting.
Every other No KYC service charges 4% (even if they claim less, do the math yourself)
Our fees are only 3% !
It seems you are also guilty of this yourself. I did the math and it turned out that fee is a little more than 3.53%. I used preev.com's Bitcoin's price in computing your fee rate, by the way.
As for the TOS, we don't have any TOS because it's No-KYC Service , Simply select the coins, deposit and wait for the coins to be exchanged and sent to your address.
Terms of Service isn't only about KYC such that if you don't ask for KYC you automatically don't need it anymore. Even legitimate decentralized peer-to-peer services have TOS. TOS is about accountability, rules, conditions, responsibilities, dispute resolution, and so on. It's always better to have a reference pertaining to all this that is agreed upon by both parties.
