Privacy

This tool runs entirely in your browser. Your taps and the tempo they produce are never sent to us or anyone else.

Comments

If you post a comment, we store your name and comment text (both shown publicly once approved), a one-way hash of your IP address, and your browser's user-agent string — used only to catch spam and enforce a submission limit. We never store your raw IP address. Comments that are rejected as spam are deleted automatically after 30 days.

Everything else

No cookies and no third-party or tracking scripts. To see which features get used, the site counts page views and a few anonymous events — such as “tapping session” — in aggregate. Each records only the event name, the page, your country and the referring site: no IP address, device identifier, tempo or tap timing is stored with it, and nothing links one event to another.
