Delete account & data
After reviewing with the service I realized that it does not fit me. I haven't found corresponding button deleting the account with all the data.
Just do it.
I removed your account and data manually. Automatic deletion is still not implemented since I have higher priority tasks at the moment.
Some time ago I received a letter from the author that after end of the trial mode, all my account data will be deleted. Now, I came to check. Account is still present, all subscriptions remained. I do not want to leave my subscription to this service. I demand urgently to delete the account and all the data.
