Cookies and device storage

More than cookies

Cookies are small values stored by your browser. MockNest also uses local storage and session storage for practice state. The rules about device storage apply to these technologies too.

The storage described below supports sign-in, security, your selected child and saved practice. Optional analytics or advertising storage must not be introduced without the required choice and legal assessment. Refusing optional storage must not prevent necessary learning features.

Cookies and storage we use

• Clerk authentication cookies manage parent sign-in and security. You can inspect the cookies and their expiry dates in your browser’s site settings.
• mn-active-child: remembers the selected child. The code can retain this for up to one year; some access flows set a shorter period.
• mn-practice-active and mn-practice-[child identifier]: support the active practice access session. Cookie lifetime: up to one day.
• mocknest_parent_unlock: confirms a recent parent PIN unlock. Lifetime: 15 minutes.
• mocknest:practice-pending:[child]:[attempt] in local storage: temporarily holds unsynchronised selected answers and elapsed time so a network interruption need not immediately lose work. It is removed when the queue is empty; there is no fixed automatic expiry for an unsent queue.
• Session storage: holds temporary sample answers and mock timing/start state for the browser session.

Optional video playback

Our video cards do not load YouTube or its remote thumbnails. Choosing Watch loads YouTube’s privacy-enhanced player, which may use cookies or other device storage for playback. No saved permission automatically loads videos on later visits. You can continue with MockNest practice without playing a video. See the Optional YouTube videos section of our Privacy notice and Google’s Privacy Policy at https://policies.google.com/privacy.

Your controls

You can inspect or remove cookies and site storage through your browser settings. Blocking necessary cookies can prevent sign-in or disrupt practice. Clearing local storage can remove answers that have not yet synchronised; finish and save work before clearing it where possible.

Removing browser storage does not delete learning records already saved to your account. To request account data deletion, contact privacy@mocknest.co.uk.
