Hi there, I’m Francesco from the Italy.
Probably my question is a little banal. I just paid for a monthly subscription, but I’d like to disable the automatic renewal. So If I try to click (from my profile) on ‘unsubscribe’, the subscription period (period just paid) is save?
Sorry for my English.
Hey there! If you unsubscribe, you’ll get to enjoy the remaining time in the subscription but after the subscription period ends, it won’t renew. If you have more support questions, @maka is the person to ask. Feel free to ask any questions! 
BTW, codecombat is nice and so you can keep and use your bought heroes after the subscription period ends!
@Chaboi_3000 is correct. If you subscribed on the 5th and cancel on the 6th, you will keep your premium access until the 5th of the next month.
Also your progress will be saved whether subscribed or not. You don’t lose progress unless you delete your own account.
Thank you so much
