What the app sends, and what it never does

The desktop app reports a few events to this site so we can tell how many people use it and where it breaks. Each event carries a random device id minted on first run, the app version, the platform, and nothing that identifies you.

• app opened — once per launch.
• session — a heartbeat every five minutes while the window is focused, and the session length on quit.
• lesson opened — which lesson, by id.
• import — the format, the note count, and whether it decomposed. Never the file.
• error — the message and stack of an error the app hit.

The website counts visits. A random id is stored in a first-party cookie the first time you arrive, and it is used to tell how many people come, how many come back, and how many projects are made and opened. There is no third-party analytics, no advertising network, no fingerprinting, and your address is never stored.

• page — which page of this site was asked for.
• project made / opened — that one was, never what is in it.
• lesson opened — which lesson, by id.
• account — that one was created or signed in to.

No document, project, score or file ever leaves your machine through telemetry, and none of it reaches the counts above either — they hold a name, a path and a number and nothing you typed. The app in the browser keeps its projects in this browser's storage and sends no document anywhere. Reporting can be turned off in Settings; the site keeps a salted hash of the sending address for abuse detection and nothing else about the connection.
