Calls

Voice and video calls can be as sensitive as anything you type, yet many services treat them as ordinary data. End-to-end encrypted calling is now mainstream and free. These guides show which apps protect calls by default, what your phone number and carrier can still reveal, and how to keep sensitive conversations off systems that log them.

Tools compared

Is the conversation itself encrypted end to end?

Readable by the provider
  • Cellular & landline calls

    Routed through carriers and legacy networks (SS7) that can intercept or log them.

  • Encrypted in transit, but Google can access the media. Fine for convenience, not for confidentiality.

Encrypted, with caveats
  • Encrypted in transit by default (Zoom can access content); optional end-to-end encryption exists but is off by default and disables some features.

  • FaceTime

    End-to-end encrypted, but Apple-to-Apple only and tied to your Apple ID.

  • WhatsApp / Telegram 1-to-1 calls

    One-to-one voice and video calls are end-to-end encrypted; Telegram group calls are not, and metadata still applies.

End-to-end encrypted
  • End-to-end encrypted voice and video, including group calls, with minimal metadata.

  • Open-source video calling you can self-host, with end-to-end encryption available for smaller calls.
