Cookies and sessions
Keeping you signed in
The gpprep_session cookie identifies your signed-in session. It is protected with HttpOnly and SameSite settings and is Secure on production HTTPS. It is set for up to seven days when you sign in and is removed when you sign out. Sign out everywhere invalidates sessions on all devices.
Remembering your theme
The gpprep-theme setting in your browser’s local storage remembers light or dark mode. It remains until you change or clear it in your browser. Clearing it restores the default theme.
Saving unfinished exam answers
While an exam answer is waiting to reach the server, your browser stores the session and question IDs and your selected answer in local storage. This lets the player retry if a save fails. The pending copy is removed after the server acknowledges it; if you never reopen that exam, it can remain until you clear site storage. Clearing it before a save completes can discard an unsaved answer. On shared devices, sign out and clear site storage after use.
