About this policy
The key details are straightforward. A cookie is a small value a browser can send back with matching website requests. Both mechanisms can be managed through your browser's site-data settings. This page explains the storage used by the built-in features of zsfh28.com. Local storage keeps data in the browser and is not automatically attached to each server request.
The contact-form cookie
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. The cookie is scoped to /api/ and expires after about one hour. The FAQ submission flow uses a cookie named spider_csrf to support request verification.
Why form storage is used
Here is what to know. 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. The token expires after approximately one hour. If the form expires, reload the page and submit again.
Local game keys
Here is what to know. 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
Keep these details in mind. These records stay in the current browser profile and domain. Keys beginning with spider-v1:stats- hold game statistics for the selected difficulty. Clearing game data removes the statistics stored by this application. Statistics can include started games, recorded wins and the best winning move count.
Remembering choices
On this website, the following points apply. The clear-data action switches saving and sound off after removing earlier records. Preference storage is used to remember your choices on later visits in the same browser. The spider-v1:preferences key stores the game-saving and sound choices. The site reads these choices when the game or settings page opens.
Duration of local storage
On this website, the following points apply. The site cannot restore local progress after that browser data has been cleared. Browser local storage does not have an automatic cookie-style expiration date. Private browsing may discard records when its session ends. The game records remain until the application, you or your browser removes them.
Your browser choices
The key details are straightforward. Blocking local storage can stop progress from being retained between visits. Privacy & Cookie Settings provides controls for this application's game records and preferences. Blocking the form cookie can prevent a contact submission from being accepted. Your browser can also remove this domain's cookies and local storage.
Storage on other websites
On this website, the following points apply. The built-in application contains no advertising or analytics integration. Activating a share link opens the selected service with the current page information. An external service can apply its own cookie and storage practices on its destination page. The built-in share buttons are links rather than embedded social-media widgets.
Questions about storage
On this website, the following points apply. Clearing browser storage does not erase a message already saved on the server. The Privacy Policy describes contact submissions and technical request information in more detail. The operator should revise this policy whenever the storage used by the site changes. Contact [email protected] for a question about this website's storage practices.
