Whatsapp increases the privacy of correspondence.

Meta (which includes Facebook, Instagram and Whatsapp) doesn't have the best reputation when it comes to the security of user data. It is not surprising that the company is trying to change this opinion and be more competitive, especially in the field of communication, because there is no shortage of alternative communicators. Recently, the ability to block chats has appeared in Whatsapp, it introduces additional authorization, without which it is impossible to open the chat in the application. We can also hide your profile picture and status from people who aren't in your contact list. And now there's the disappearing voicemail feature. When recording a message, you can select the "one-time message" option. After the recipient listens to the message, it will be deleted and you will only be prompted that there was such a message. This is certainly a step in the right direction in terms of correspondence privacy.
