Secure Instant Messenger chat apps
The list includes: Our recommendations might not be very comfortable because not everyone is available on these messengers. So you will have to ask your friends to use it or educate your group to move to one of these platforms. So find a balance between conversations you want to keep a secret and with those which are casual. Keep in mind that not all of them are built to keep your messages forever.
1] Signal
The Signal App is made using a platform which is solely for privacy. All the messages are encrypted using the Signal Protocol. The protocol is known to be the most secure text messaging protocol. Technically, it uses HMAC-SHA 256-bit, AES 256-bit, and Curve25519. When you create a profile, not even Signal can see have any knowledge of the name you have chosen or the image you have set. It finds contacts; signal periodically sends truncated cryptographically hashed phone numbers for contact discovery. It is available for Desktop, but you will have to first install on Phone and register. Later you can link the desktop to phone, and it works seamlessly. It offers self-destructing messages, option to delete all the messages and other regular messages. Signal unlike other platforms like WhatsApp and Facebook messenger doesn’t collect any metadata. They don’t create a profile using which you can be targeted with an advertisement or anything else.
2] Wickr
It’s useful and free for a small group of a maximum of ten people. You create a network, invite people, share files, and your data is available for a maximum of 30 days. The messages can be timed to self destruct from anywhere between one second to up to six days. They are wiped clean from the computer, and users can choose to delete metadata as well. The process makes sure that no trace of messages is available on the device. Lastly, it doesn’t require you to upload your contacts. Download it from here.

Also, the servers are in Germany and Ireland.
4] Telegram
There are many other great instant messengers available, but they are not available for desktop. They offer similar features but have restricted themselves to be on mobile. Telegram is one such example where it doesn’t provide the secret chat feature on the computer. The secret chat allows you to self destruct message as soon as they are seen or based on time. But then we all have a mobile, and it only makes sense to use Telegram. All your secret conversation stays on your phone, and with auto-destruct, messages will be completely wiped off your device.
