1. About this policy
This policy explains browser storage used by Guangzhou Carbon Link Intelligent Technology Co., Ltd on carbonlinksci.com. Cookies are one form of browser storage; this website also uses local storage to remember privacy choices.
2. Privacy preference storage
Name: a site-specific local-storage key beginning with carbonlink-consent:
Type: browser local storage, set by this website.
Purpose: remember whether optional analytics were accepted or rejected, together with the preference version and expiry time.
Contents: choice, version and expiry; it does not contain the name, email address or requirements entered in an inquiry.
Validity: 180 days after saving a choice. Local storage does not automatically expire like a cookie: the website checks the stored expiry and removes an expired record when it next reads it. Data may remain on an unused device until the site reads it or you clear site storage.
A changed preference version may require a new choice before optional analytics can run. Clearing browser storage also removes the saved preference.
3. Optional analytics
Optional analytics are currently disabled. The Allow analytics button is unavailable while this feature is disabled. We will identify any analytics provider, purpose, data and storage duration here before enabling it. Future analytics will not be enabled merely because you continue browsing.
4. Login and other storage
Staff who access the administration area may encounter authentication and settings storage that is separate from ordinary visitor browsing. These are first-party WordPress functions on this website.
WordPress uses cookies with wordpress_ and wordpress_logged_in_ prefixes to maintain staff sign-in, and wp-settings- and wp-settings-time- cookies to remember staff interface preferences. A wordpress_test_cookie may be used on the login page to check cookie support. Login duration depends on the sign-in options and site settings. Settings cookies are configured to last one year. The editor can also store staff preferences in local storage under a WP_PREFERENCES_USER_ key, which may remain until removed. WordPress uses the wpEmojiSettingsSupports session-storage key to cache browser emoji-support checks. Clearing browser storage may remove these settings or sign staff out.
5. Changing your choice
Use Privacy preferences to reopen the controls. Where analytics are enabled, you can reject them or withdraw a previous choice. This stops subsequent requests from this website's optional analytics mechanism and attempts to cancel requests still in progress; it cannot recall information already received by a service.
If your browser prevents the preference from being saved, the website displays a message and keeps optional analytics off on that page. Your choice may not persist across visits when storage is unavailable. You can also manage or clear site data through your browser settings; clearing login storage may sign staff out.
Rejecting optional analytics does not block an inquiry. The inquiry-processing acknowledgement on the form is a separate control.
6. Contact and changes
For questions, contact DmEloy656@gmail.com. More information about inquiry records appears in our Privacy Policy at https://carbonlinksci.com/policies/privacy/. We will update this policy if storage or services change.
