From what I understand "You can check out any time you want, but you can never leave."  Bro, you're in Hotel Chinafornia now :-)

 Like a lot of sites, it is easy to create an account, but deleting..... not that well documented if possible at all.

However, Autel won't spam you or anything as far as I know so why not just leaving the account as it is, it won't bother you. Just don't login and forget it is even there.

 That's a good thought! hehehe
