CHEVIR - Privacy Policy

Last updated: 13 November 2026 · Windows (Microsoft Store)

Summary: CHEVIR creates no account and contains no ads or analytics; no data reaches Hidroteknik. While translation or the prompter is running, the audio of the call and the working file you selected are sent directly to OpenAI, using the OpenAI key you enter yourself.

Data we collect

  • There is no account, membership or profile.
  • There is no telemetry, analytics, advertising or third-party tracker.
  • Hidroteknik runs no server for this app: no audio, text or usage information reaches us.

Data sent and recipients

To do its job, CHEVIR sends the following directly from your computer to OpenAI, using the OpenAI API key you enter yourself:

Sending starts only after you press Start and ends when you press Stop, when the time limit is reached, or after a long silence. While translation and the prompter are off, nothing is sent to OpenAI. How OpenAI handles this data is governed by your own agreement with OpenAI and by OpenAI’s privacy policy.

  • While translation or the prompter is running: the audio of your microphone and of the other side of the call.
  • While the prompter is running: the text of the conversation and the contents of the working file you selected (and your company file, if you filled one in).

Data kept on your device

To delete everything, uninstall the app and delete the "CHEVIR" folder in your Documents.

  • Your OpenAI key, your settings and technical log files are stored in the app’s local data folder; the key is never sent to us.
  • Your working files are stored in the "CHEVIR" folder in your Documents.
  • Call audio is not recorded. The text of your calls is not written to disk unless you turn on the development log yourself.

Audio settings

CHEVIR switches the Windows default audio devices to the virtual audio cables so that the translated voice reaches the calling app, and restores the previous devices when it is done. This can be turned off in Settings.

Other people in the call

Where the law requires it, you are responsible for informing the people you talk to that the call is processed by a translation and transcription service.

Third-party software

Voice translation requires the VB-CABLE and HiFi Cable virtual audio drivers by VB-Audio, which you install yourself from vb-audio.com. They are third-party software with their own terms.

Children

CHEVIR is not directed at children. We do not knowingly collect data from anyone under 13.
