Privacy
Placeholder. This prototype has no backend and no accounts, and measurement is limited to anonymous page views and page-load timings. What follows describes the prototype rather than a released service; a released version would need a reviewed privacy policy in its place.
What is stored
Your practice history, bookmarks, mock exam progress, scratchpad notes, your light or dark theme choice, and any error reports you write are saved in your own browser using localStorage. They stay on the device you used and are not transmitted anywhere.
What is measured
Two measurements run, both from Vercel. Web Analytics counts page views, so it is possible to tell which topics are actually being used. Speed Insights records how long a page took to become usable, so a slow page can be found and fixed. Neither sets a cookie, builds a profile, or follows you to other sites.
Between them they record the page address, the referring site, an approximate country, the kind of device and connection, and page-load timings — never the contents of a page.
Nothing you type is measured. Your answers, scratchpad notes, bookmarks and results are not part of it and never leave your browser.
What is not collected
No account is created and no email address is requested. There is no advertising, no advertising network, and nothing that identifies you across sites. No server receives your practice answers.
Removing your data
Clear all progress on the progress page removes the stored history. Clearing site data for this domain in your browser removes everything, including scratchpad notes and saved exam sessions.
Fonts
Typefaces are served from this site rather than fetched from a third-party font service, so loading a page does not reveal your visit to anyone else.
