RF Lab · effective September 11, 2026
The short version: RF Lab doesn't collect, transmit, or even look at anything you do with it. There's no server behind this app, no account, and no analytics - the author has no visibility into how you use it or what data it holds.
All of your data - sweep results, memory/overlay traces, THRU calibration, instrument
addresses, theme choice, and window position - is saved only on your own
computer, under %LocalAppData%\RfLab, and wherever you choose to
export files (CSV, PNG, or an MD Visor report). Nothing is ever uploaded anywhere.
The only connection RF Lab makes is the one you set up yourself: a serial (COM port) connection to a compatible NanoVNA text-console device. It does not contact any server operated by the author - no update checks, no license phone-home, no crash or usage reporting.
No cookies, no analytics SDKs, no third parties involved. This applies equally whether you're evaluating, using, or have long since stopped using the app.
If anything here is unclear, reach out to petr@fotoventus.cz. Since no usage data or documents ever reach the author, there is nothing to look up on request beyond answering your question.
Any future change to this policy will be published on this page with an updated date.
