Cookie and Local Storage Policy

1. Scope

This policy explains cookies and browser storage used by Shuangmu AI Learning Hub, operated by 双木拾光（烟台市）人工智能研发有限公司 (referred to as “双木拾光” or “we”), in its current read-only mode. Cookies are small records stored by a browser and may be sent with matching website requests.

2. Language cookie

Through next-intl, the site may set a cookie named NEXT_LOCALE when language state needs synchronization. It records the language currently visited; the URL determines the page language.

This is a session cookie with no configured persistent expiration time. It is usually cleared at the end of the browser session, subject to browser settings. Its SameSite attribute is Lax.

3. Local storage for theme preferences

The site uses localStorage["theme"] to save your selected appearance theme. This is browser local storage, not a cookie; it is not automatically sent with matching HTTP requests in the way cookies are.

The record has no expiration time set by the application. You can change the theme or clear it through your browser’s site data controls.

4. Analytics services

Google Analytics, Microsoft Clarity and other third-party analytics services are currently not enabled. If analytics services are enabled in the future, we will update this policy.

5. Managing and clearing storage

You can manage, restrict or delete cookies and local storage through browser settings. Restricting cookies may affect language synchronization. Clearing the theme record resets your preference; public content remains available.

6. Policy updates

We will update this policy and its effective date when cookies, local storage or related features change.
