TextLock - Encrypted Messages

About TextLock - Encrypted Messages Android App

Have you ever been afraid that someone might read your messages or emails on your phone?
Have you wanted to be able to send private messages that everyone can read, yet no one can understand?

Well, you're in luck, because with TextLock, you can do exactly that.
TextLock uses a modified and a much more secure version of the Vigenère cipher so that your messages are encrypted in a way that cannot be decrypted by even the most powerful of computers. Once you enter your message and set a password, you can share the encryption with whoever you want, through any sort of social media and only the people with the password will be able to decrypt it. You can send encrypted messages on a group chat, so that the people with a password understand it, while the rest are left in the dark. It is the most simple solution to your privacy problems.

Are you still going to risk sending your messages without encrypting them?
