Privacy
This page explains what data this app stores and how it is used.
Settings & practice results
Your settings and practice results are stored only in your browser's localStorage, on your own device. Nothing is sent to a server, and there is no account or login — clearing your browser data removes it.
Usage statistics
This app uses Vercel Analytics to collect anonymous, aggregate usage statistics (such as page views). This data is not tied to your identity and contains no personal information.
Cookies
No cookies are used for tracking — this app is essentially cookie-free.
