Another person requested a review, so here it is. Thought it's obvious it's terrible so I'll be brief here. Phone number requirement during registration makes Soverin completely non-anonymous - and for me, alone disqualifies it. Privacy policy says nothing about what data they actually store and for how long - only that if you delete your account, it's all gone. Soverin dares to ask for money for this abuse - and through a third party payment processor that collects everything possible about you and even shares it with others - "Mollie will share your personal data with third parties if this is necessary for the performance of the contract or if it is based on legal obligations or legitimate interests." As for some positives - well, mail clients are apparently allowed, as well as Bitcoin. But if their payment processor stores so much stuff, does it even matter? There is disk encryption...who cares, everyone now does it. If you really want to part with your money, get Posteo that is 3 times cheaper and much better. Or just go for the good free ones like RiseUp or Disroot.
