You need to visit the okd website cloudmagic and login to acc, then from panel you can visit Stripe and cancel subscription if you ever subscribed and paid on web. If you using app store just contact Apple or cancel from your iTunes account where you see all apps subscriptions.
Yesterday I switched to Spikenow, and Im loving it. Many great features like email organization bz subject or people.. Read notifications by default, its fast, it has unified inbox although I not like it at first but as I use it more I can see its really useful thing. Canceled my newton subscription yesterday even it last until May 2023, I am just tired of their lack of support, no updates..who knows even if our data is safe with them at this point. (Just copying my comment from previous threads where I replied). The more users know about good alternative is better. Newton honestly has left us alone and they totally not deserve anyones money anymore
