Privacy
This site does not ask for, collect or transmit any personal information. There is no account, no login and no form.
Your chosen interface language and your practice progress are kept in your own browser using local storage. They never leave your device and are not visible to anyone else, including us. Clearing your browser data removes them.
The site loads web fonts from Google Fonts. Requests to that service reveal your IP address to Google under their own privacy policy. Everything else is served from this domain.
If advertising is added in future, this page will be updated before it goes live to state exactly what the advertising partner collects and how to control it.
