SCAM! Do not subscribe.
SCAM! Beware! Asana Rebel renewed my subscription for two years (worth €71) without any prior warning that the subscription was up for renewal and that it would be renewed for TWICE THE AMOUNT I had originally subscribed for. I is so long ago since I last even looked at the app, that I had forgotten that I even had the subscription, so a reminder would have been nice, but looking at some of their other dark design patterns, I think this kind of obfuscation is done totally on purpose.
They know this is an issue and have been told about it before, because when you navigate to the "cancel my subscription" form of the website, they state in red letters that a cancellation will not result in a refund.
There are threads on Reddit about them and how they refuse any refunds and claim that their shady terms and conditions make it "ok" for them to behave in this manner. The fraudulent charges will stand even though you contact your bank to cancel the payment.
So it's a total SCAM. Be VERY careful about signing up, and if for some reason you still decide to do so, set yourself a reminder ahead of the stated renewal date, as Asana Rebel is happy to take your money even if you haven't used the service for ages.
