Your phone may say that data is end-to-end encrypted if you are using a messaging or communication app that provides this feature. End-to-end encryption means that only the sender and intended recipient of a message can read its contents, as no one else, including third-party apps and service providers, has access to the data being transmitted. This provides an extra layer of security and privacy for your conversations and data, as there is no third-party access or interception of your messages. If you value your privacy and security, it is recommended that you use apps and services that prioritize end-to-end encryption.
