The messenger is the one and only with encrypted database in the world. It is the only messenger that can protect your messages from espionage.
How it can protect your messages from espionage ?
Generally messaging companies possess admin panels. And if any employee of the messaging company is compromised then user's messages are compromised.
In this messenger, entire database (where messeges are stored) is encrypted (data converted into a secure and unreadable format). So there is no way somebody can decode the encrypted messages. Because messages are encrypted with the highest level of custom made algorithm (based on unbreakable AES, RSA algorithms). There is one more security layer for the database that is only known to the founder of Product-Bank.
