Uh, cryptostorm doesn't leak. As parityboy explained in viewtopic.php?f=32&t=9568&p=18351#p18351
, your problem was that your device was set to proxy through opera-mini.net after tunneling through cryptostorm.
Connecting to a VPN won't change your browser's proxy settings.
If you see your real IP or ISP's DNS anywhere, you need to read the tutorials again to make sure that you set up your device correctly. Also, don't forget to do a ctrl+f5 refresh if you're using ipleak.net, since sometimes those results get cached.
The download page at https://cryptostorm.is/#section6
now includes various tutorials for all the popular systems.
