Telegram connects people via a unique distributed network of worldwide data centers. Updated versions feature haptic feedback when a call partner activates video transmission and better performance when sending messages in group chats. This allows you to use the app anonymously without revealing private information. Each Threema user also receives a random Threema ID - which means no phone number or email address is required. You can reply with the app’s agree/disagree feature and verify the identity of a contact by scanning their personal QR code. Encryption keys generated are stored on your device to prevent backdoor access or copies. Messages are deleted after delivery, and local files from conversations are also encrypted. It generates very little server-based data, and group memberships and contact lists are stored directly on your device, not in the cloud. Using the open-source NaCl cryptography library, the app encrypts all communication. You can use Threema anonymously to make end-to-end encrypted voice calls, send texts and voice messages, share videos, and even conduct polls.

Sure, using an encrypted messaging app is way better than nothing - which is to say, better than Skype, Windows Messenger, or AIM - but if you’re concerned anyone could listen in to your conversations or read your messages, then a VPN provides an added layer of reassurance. If you are considering encrypted messaging, the best way to achieve the utmost privacy is to also use a private VPN connection. While no encrypted messaging app is perfect, we round up the best ones available. Apple owns the highly regarded encrypted iMessage, but that app does not encrypt data like mobile numbers, metadata, or data stored in the cloud. For example, Facebook Messenger and WhatsApp are both encrypted and work quite well, but they are also owned by Facebook, which has a problematic historical relationship with privacy.
While there are quite a number of good encrypted apps out there, many have flaws associated with their operations, their owners, or both.
