Encrypted Calls

Buzzio private calls let you place voice and video calls with someone in 1-to-1 chat. Setup is encrypted, media is meant to travel device-to-device when networks allow, and Buzzio does not keep a server recording you can play back later.

Use calls when you want a live conversation with the same private-chat trust model — without turning the call into a cloud archive.

Get started

  1. Open a 1-to-1 chat with the person you want to call.
  2. Tap the voice or video call control in that chat.
  3. Or open the Call tab to see recent local call history and return to people you have called.

During a call you can mute, use speaker, turn the camera on or off, flip camera, share your screen, and end the call.

What a Buzzio call includes

  • Voice and video for private 1-to-1 conversations
  • In-call controls: mute, speaker, camera, flip, screen share, end
  • Screen share pauses both cameras so only the screen is shown; one share at a time
  • Android: press Home to show another app while sharing — capture continues from the call notification
  • iOS: start share from the system Start Broadcast picker (choose Buzzio)
  • A Call tab for recent calls stored on your device

How privacy works for calls

  • Call setup (the “ring / connect” path) is encrypted and is not kept as a permanent call dossier.
  • Call audio and video use peer-to-peer connection when possible. If a direct path is blocked, Cloudflare TURN relays encrypted packets so the call can still connect. The relay cannot play back or listen to the call.
  • We do not record calls. There is no Buzzio server playback archive of your call audio or video.
  • The call history you see in the app lives on your device. The Call tab hides older records after about 24 hours.
  • When nothing needs to stay for an active setup, private calls are treated like other sealed surfaces: no lasting server file of who called whom for browsing.

Tips and limits

  • Calls are part of private 1-to-1 chat — start from a chat, or return through the Call tab.
  • Keep a stable network for the best voice and video quality.
  • If someone blocks you, you generally cannot keep calling them through that private relationship.
  • Your on-device call list is for convenience; it is not a Buzzio cloud call archive.
  • 1-to-1 chat — the same private surface where message history and call buttons live.
  • Whisper private chat — time-limited QR sessions for messaging; not the main place to start lasting voice/video identity calls.
  • Notifications — turn call alerts on or off in notification settings, and set a call ringtone.
