How to leave unknown cookies not deleted by default?

CookieScript scans your website and groups cookies by categories using our database of cookies. Then, all cookies from cookie declaration are handled according to their category. For example, if you checked to keep just strictly necessary cookies, only strictly necessary cookies will remain active, other cookies will be deleted by default.

All unknown cookies are deleted by default. To keep unknown cookies, go to your CookieScript user account > Settings > Cookie behavior, and check the Keep unknown cookies checkbox.

If the cookie was not found during the scanning process, it is treated as an unknown cookie and with this checked option the unknown cookie will not be deleted. Choose this option to prevent deletion of cookies missed by the scanner, such as those set after logging in.
