Privacy Policy

Muzika analyses songs on your Mac. It collects nothing about you and sends nothing about your songs anywhere.

What stays on your Mac

• Your audio files. They are read from where you opened them and are never copied, uploaded or shared. The app keeps only a reference to the file and the report it produced, in its own container.
• Lyrics. Transcription runs on the device with Apple's speech recognition; no audio or text leaves the Mac.
• Reports. Every analysis is stored locally as a file you can delete from the sidebar at any time.

The one network request

Once a month, if you leave the option on in Settings, the app fetches https://tkgdata.com/muzika/model.json — a file of a few hundred kilobytes holding statistical coefficients and percentile tables derived from public chart data. The request is a plain conditional GET: it carries no identifier, no account, and nothing about you or your songs. Our web server logs the request as it logs any page view (IP address, time, user agent), and those logs are rotated automatically. You can switch the refresh off; the app then uses the copy it shipped with.

What the model file contains

Fitted regression coefficients, confidence intervals and per-era percentile tables. It contains no song titles, artists, lyrics or chart rows.

Analytics and advertising

There are none. No analytics framework, no advertising SDK, no crash reporter, no third-party code.
