When it comes to messaging and privacy, every messaging app is different. Messaging apps that are known for being the most private use something called end to end encryption. This means the messages you send someone else will stay encrypted and even if the message passes through or is stored on a server, they are encrypted in a way the service provider can not read it's contents. Apps that do not offer end to end encryption all the time, offer end to end encryption in private messaging settings that the user must manually turn on, something most people do not do.
Although end to end encryption does not seem important, it can prevent your personal and private information from being stolen. Companies like Google and Facebook don't use end to end encryption as a default because it does not benefit them. Google and Facebook go into users messaging and builds features like chatbots, advertisements, and response predictions. Companies like Snapchat, who are known for automatically deleting messages as soon as they are read, encrypt messages as they are transmitted, this helps to prevent hackers intercepting them, but they keep the encryption keys to which gives them the ability to access the messages. Even though end to end encryption helps significantly when it comes to user privacy, like every technical process, it does not guarantee complete privacy. Encryption methods can be cracked but so far, this is the best tool users have to protect their privacy when it comes to smartphone messaging apps.
