Privacy Policy

Last updated: 30 June 2026

Summary

It's 404, yo! collects no data. The app runs entirely offline on your Mac. Your sample files are read and converted locally and never leave your computer.

What we collect

Nothing. There is no account, no sign-in, and no cloud service. Specifically:

• We do not collect any personal information (name, email, IP address, or device identifiers).
• We do not track your usage of the app.
• We do not use analytics, cookies, or any third-party tracking.
• We do not transmit your audio files or any other data off your Mac.

Local file processing

All inspection and conversion happens on your device using Apple's Core Audio frameworks. The app only accesses the files and folders you explicitly choose, and writes converted output to a location you pick. Nothing is uploaded anywhere.

Changes to this policy

If this policy changes, the updated version will be posted on this page.
