I created an account on this website to test if it works for me.
Since I am still receiving promotional spam from for which I unsubscribed many times now, I would like to definitely deactivate my account. However, I can’t find any option to do so in my preferences. (It was a huge pain to get to my preferences in the first place, since I was getting a pop-up when opening the app telling me I had to choose a plan, making me unable to get into preferences).
Please, just let your users deactivate their accounts from the service you don’t provide.
