Privacy policy
Last updated: September 2026
1. What data we process
The audio tools (tuner, ear trainer) request microphone access to work. That audio is processed entirely in your browser and is never sent to or stored on any server.
2. Local storage
Some tools (e.g. the royalty split calculator) may save information in your browser's local storage (localStorage) so you find it on your next visit. That information stays on your device, not on our servers.
3. Advertising and cookies
We use Google AdSense to show ads. AdSense may use cookies to show relevant ads based on what you accepted in the cookie notice. See the cookie policy for details and how to change your choice.
4. Analytics
We may use aggregate analytics tools to understand which pages are visited most, without personally identifying individual users.
5. Your rights
You can delete data stored in your browser at any time from your own browser settings, and reject non-essential cookies from the cookie notice.
6. Contact
