Privacy Policy
Last updated: 21 September 2026
Your audio files are never uploaded
This is the part that matters most, so it comes first. When you drop a file into the converter, it stays on your device. Your browser decodes it locally with the Web Audio API, the pitch analysis runs in your browser tab, and the MIDI file is built in your device's memory. The file is not sent to this site, and it is not sent anywhere else. No copy of your audio is kept anywhere.
The converter page makes no network request with your file. It has no upload endpoint to send one to.
What we do not ask for
- No account and no sign-up.
- No e-mail address, name, or any other identifier to use the converter.
- No payment details — the converter is free.
Cookies and analytics
The converter itself sets no cookies and stores nothing in your browser's local storage. At the time this page was last updated, the site does not run a third-party analytics product. If that changes, this page will be updated before it changes.
Advertising
The site may carry third-party advertising in the future in order to keep the converter free. Advertising providers commonly set their own cookies or similar technologies and may collect information such as your IP address and the pages you view, in order to serve and measure ads. We do not control those providers, and their handling of that information is governed by their own privacy policies. This page will be updated before advertising is added.
Server logs
Like most websites, the hosting of this site can produce ordinary technical records such as the requested address, time, and a coarse network-level identifier. That is a property of how the site is served over the internet, not something this site collects about you as a person, and it is not linked to your audio files, because those never reach the server.
Children
The converter is a general audio tool. It is not directed at children and does not knowingly collect anything from anyone.
Changes
If this policy changes, the updated version will be posted on this page with a new "last updated" date.
