Mochicast is a lightweight Windows app for streaming your desktop and audio into VRChat. It now supports both classic HLS streaming and new low latency streaming, so you can choose the mode that fits your setup.

Telemetry & privacy

Mochicast collects a small amount of technical telemetry so I can see whether the app is working, understand how the streaming service is being used, find failures and improve performance. It is not advertising telemetry and it is not used to build a profile about you.

I WILL NEVER SELL YOUR TELEMETRY DATA TO ANYONE.

What Mochicast telemetry can collect

  • A randomly generated anonymous installation ID
  • Mochicast app version
  • Streaming mode being used
  • Resolution, FPS and selected bitrate
  • Encoder type, such as NVIDIA NVENC or x264
  • Stream session duration and current viewer count
  • Reconnects, failed starts and technical error events when reported
  • Server region and service-level usage statistics

What telemetry does NOT collect

  • Your email address, name or VRChat username
  • Your screen or the contents of what you are streaming
  • Your desktop audio or the contents of your audio stream
  • Your files, filenames, browser history or messages
  • Your passwords or payment card details
  • Advertising identifiers or data for targeted advertising

Where the data goes

  • Telemetry is sent only to Mochicast infrastructure
  • Telemetry is kept on the Mochicast server and used to operate, troubleshoot and improve the service
  • It is not sold to advertisers, data brokers or other companies
  • Account information is handled separately from anonymous streaming telemetry

Streaming security

  • Mochicast web, account and telemetry connections use HTTPS/TLS encryption in transit
  • HLS playback is delivered over HTTPS, so HLS video traffic is encrypted in transit
  • Low-latency VRChat RTSPT is not encrypted in transit. Mochicast tested RTSPS, but the current VRChat/AVPro playback path does not accept it, so the compatible low-latency mode remains RTSPT
  • Stream content is not collected as telemetry and Mochicast does not create recordings of your streams for analytics
  • Stream access uses unique stream links/keys rather than exposing your account details in the stream

Plain English: I collect the boring technical stuff I need to keep Mochicast working. I do not need or want the contents of your desktop, your stream, your messages or your personal life.

Beta notes

RTSPT gives sub second latency. HLS is around 8 seconds because of video buffering.

Security note: HLS playback uses HTTPS and is encrypted in transit. The current low-latency RTSPT mode used for VRChat compatibility is not encrypted in transit.

This app is still in development.
