What is end-to-end encryption and why does it matter

End-to-end encryption means your messages are locked with a code that only you and the person receiving them can unlock. Nobody in between, not even the app company, can read them. Think of it like a letter in a locked box that only has two keys, one for you and one for the recipient.

End-to-end encryption protects your private conversations by making them impossible for anyone to read except the person you are talking to. Without it, the company running the app, hackers, or governments could intercept and read your messages. With it, only the two of you can understand what you are saying.
