Each Threema user generates a random Threema ID. No phone number or email address is required in order to use Threema. This enables you to use Threema completely anonymously.
Threema end-to-end encrypts all your communication including messages, group chats, files and even status messages. Only the intended recipient, and nobody else can read your messages.
Threema is a 100% independent and self-financed company in the heart of Switzerland with its own servers and in-house software development. Switzerland is a country with some of the most user friendly privacy laws in the world.
Threema is designed to generate as little data on servers as possible: Groups and contact lists are solely managed on users’ devices, messages are immediately deleted after delivery. This effectively prevents the collection of meta data.
ProtonMail is incorporated in Switzerland and all the servers are located in Switzerland. This means all user data is protected by strict Swiss privacy laws.
All emails are secured automatically with end-to-end encryption. This means even they cannot decrypt and read your emails. As a result, your encrypted emails cannot be shared with third parties.
No personal information is required to create a secure email account. By default, they do not keep any IP logs which can be linked to your anonymous email account. Your privacy comes first.
