Threema

Threema is a simple and intuitive messenger. Its main distinction from WhatsApp for Android and Telegram is its enhanced security. Every text and voice message, along with every media file, undergoes end-to-end encryption before being sent to the recipient.

Encryption keys are generated randomly and stored in special protected folders on your device, completely preventing any possibility of copying or deletion. Alongside these positive qualities, the program offers all the necessary features modern users need, including sending music, GIF animations, images, and documents, creating chats and groups, customizing the appearance, and synchronizing contacts, among many others.
