Calculators run in your browser. Student accounts store your email address, password hash, profile details, optional photo, saved tools, bookmarks and exam progress on this website’s server. Session cookies keep you signed in and protect forms. Guest practice is stored in a server session; unsubmitted selections can also be held in your browser tab. Verification and password-reset emails are sent through the configured Gmail service. Official-notice checks contact examination authority websites without sending your student profile. Your host may retain access logs. Sign out on shared devices. Contact the site administrator to request account deletion or a copy of your stored information. No analytics or advertising code is added by this update.
