Hi, I installed Bittorrent Sync 1.4.110. I read some topics regarding privacy, and I understand hash is not privacy data. But I would like to use Bittorrent Sync as pure P2P system. Share(mail,copy,QR code) will use internet connection(https://link.getsync.com/~). So I will use "copy key" in settings. I disalbed both "use tracker server" and "use relay server". I believed this will work pure P2P system. But I found my firewall logs continue to show connection between ec2-54-225-196-38.compute-1.amazonaws.com UDP 3000 and my local pc. How can I stop this? To disable "use relay sever" does not work?
