Started a free trial of a premium service whilst on holiday, and cancelled the free trial well in advance of the date it rolled into a paid subscription. However, Duolingo don't seem to think that cancelling the free trial means you want to cancel the subscription, so after I had long forgotten about this app they charged me £60 and put me on the premium subscription. That is a considerable amount of money to steal from unsuspecting users due to an explicit design choice Duolingo have made to trick customers. DO NOT START ANY FREE TRIALS - it could cost you a lot of money. Even though you try to block the transaction and stop it on the same day - this company does not offer refunds, and does not have an option to stop premium subscriptions partway through the year, so they have stolen £60 from me and I have no way to get it back. No help from the app store either. On a separate note, this app is not helpful in learning new languages. Instead you learn the muscle memory to press buttons on the right order quickly, but you are not learning to speak a new language.
