About this policy
The key details are straightforward. Local storage keeps data in the browser and is not automatically attached to each server request. This page explains the storage used by the built-in features of qzhzkj.com. Both mechanisms can be managed through your browser's site-data settings. A cookie is a small value a browser can send back with matching website requests.
The contact-form cookie
Keep these details in mind. The FAQ submission flow uses a cookie named spider_csrf to support request verification. The cookie is scoped to /api/ and expires after about one hour. The application marks this cookie HttpOnly and SameSite Strict, and uses the Secure flag on HTTPS. The cookie contains a random value rather than your question or email address.
Why form storage is used
Here is what to know. If the form expires, reload the page and submit again. The token expires after approximately one hour. The server checks the form cookie together with a signed token when a question is sent. The check helps reject requests that did not originate from the protected form flow.
Local game keys
On this website, the following points apply. One suit, two suits and four suits use separate saved game records. A saved record includes the card layout and recent undo history so that play can resume. Turning off game saving removes those application game records. Game progress is stored under local-storage keys beginning with spider-v1:game-.
Statistics keys
Statistics can include started games, recorded wins and the best winning move count. Keys beginning with spider-v1:stats- hold game statistics for the selected difficulty. Clearing game data removes the statistics stored by this application. These records stay in the current browser profile and domain.
Remembering choices
The key details are straightforward. The clear-data action switches saving and sound off after removing earlier records. The spider-v1:preferences key stores the game-saving and sound choices. Preference storage is used to remember your choices on later visits in the same browser. The site reads these choices when the game or settings page opens.
When local records expire
The key details are straightforward. The game records remain until the application, you or your browser removes them. Browser local storage does not have an automatic cookie-style expiration date. The site cannot restore local progress after that browser data has been cleared. Private browsing may discard records when its session ends.
Manage or block storage
Keep these details in mind. Privacy & Cookie Settings provides controls for this application's game records and preferences. Your browser can also remove this domain's cookies and local storage. Blocking local storage can stop progress from being retained between visits. Blocking the form cookie can prevent a contact submission from being accepted.
External share services
On this website, the following points apply. The built-in share buttons are links rather than embedded social-media widgets. Activating a share link opens the selected service with the current page information. The built-in application contains no advertising or analytics integration. An external service can apply its own cookie and storage practices on its destination page.
Contact and related information
Here is what to know. The operator should revise this policy whenever the storage used by the site changes. The Privacy Policy describes contact submissions and technical request information in more detail. Clearing browser storage does not erase a message already saved on the server. Contact [email protected] for a question about this website's storage practices.
