  • Messages in iCloud are E2EE protected only if iCloud Backup is disabled or if iCloud Backup is enabled with Advanced Data Protection (ADP). Otherwise, Apple stores a copy of the encryption key, allowing Apple (or authorities with a court order) to access your messages.

  • Probably obvious, but messages sent over SMS (green bubbles) are not E2EE.

  • Telegram uses a proprietary encryption protocol called MTProto, so who knows if it can be trusted.
