End-to-end encryption (E2EE) is a method of protecting data from unauthorized use. E2EE relies on encryption (glossary), but not all apps using encryption are encrypted end-to-end.
Apps that use end-to-end encryption ensure that their data is unprotected only when unlocked for use by a key, which can be used only by you and not your service vendor. It's important to remember that having a password on an app doesn't mean its data is end-to-end encrypted.
