About

An independent implementation, not affiliated with any third-party site. It uses no third-party trademarks, copy, images, or audio.

Every question is computed in your browser from parameters. The staves are SVG lines drawn here; the sounds are waveforms synthesised here. Nothing was copied from anyone's site.

Where your data lives

There is no server and no account. Progress is written only in this browser on this device. It does not follow you to another device, and clearing browser data removes it.

Using it offline

After your first visit the whole site is stored in the browser cache. Open it with no connection and everything still works, including the ear exercises — the sound is synthesised on the spot, so no audio files are downloaded.

Privacy

We collect nothing. No account, no cookies, no analytics, no ads, and no requests to any third-party server. The only thing stored is a single key in this browser's localStorage (mp.progress.v1: points, answer history, appearance preference), and it is never sent anywhere. Clearing your browser data deletes it; you can also export or erase it on this page.

Terms

Free to use, provided as is, with no warranty. This is a practice tool, not a course provider, and it is not affiliated with any exam board. Questions are generated from parameters, so mistakes happen; tell us when you find one. Everything here is an independent implementation and uses no third-party trademarks, copy, images, or audio.

Your progress

Progress lives in this browser only. There is no account, so changing device or clearing browser data will lose it.
