Frequently Asked Questions

Is my audio ever sent to the cloud?

No. All inference happens completely locally on your hardware. The Docker container does not make any external network calls to third-party transcription endpoints.

How many users can access the server?

The Business License covers unlimited internal users within your company accessing the server via the Web UI or your internal apps.

What happens after the first year?

Your perpetual license never expires. You can continue using the software forever. If you wish to receive further updates and support after the first 12 months, you can optionally renew for $249/year.

How does offline activation work?

We use a hardware fingerprint system. You generate a fingerprint on the server, upload it from an internet-connected device, and receive a signed license.key file to place on your air-gapped server.

Does the server require internet access after installation?

No. After the Docker image and license are installed, transcription and inference run completely offline without internet access.
