The short version: no accounts, no ads, no tracking script, no cookies set by this site. Your progress stays in your browser.
What is stored, and where
- Drill history (time and score per topic) and mock exam progress (answers, flags, time left) are saved in your browser’s local storage so you can pick up where you left off.
- They never leave your device. Clear them with the “Clear my history” button on a drill page, or by clearing this site’s data in your browser.
What the server sees
The site is static files on a hosting server. Like any web server, it receives your IP address, browser type and the page requested, and it keeps standard request logs to run and protect the site and to count visits. There is no tracking script and nothing is sold or shared.
Changes
If this changes, for example if a paid pack with accounts is added, this page will be updated first and the change logged in the change log.
