End-to-End Encryption (E2EE)
Encryption where only the people communicating can read the messages β not the service carrying them.
With end-to-end encryption, content is encrypted on your device and only decrypted on the recipient's device. The provider in the middle — and anyone who compromises it — sees only ciphertext, never the plaintext.
Why it matters: a service that holds the keys can read, hand over, or lose your data. True E2EE removes that single point of failure. Watch for the difference between “encrypted” (often only in transit or at rest) and genuinely end-to-end.
