Cookies and browser storage
On this website, the following points apply. Local storage keeps data in the browser and is not automatically attached to each server request. Both mechanisms can be managed through your browser's site-data settings. This page explains the storage used by the built-in features of xpxyxx.com. A cookie is a small value a browser can send back with matching website requests.
spider_csrf
The key details are straightforward. The FAQ submission flow uses a cookie named spider_csrf to support request verification. 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 application marks this cookie HttpOnly and SameSite Strict, and uses the Secure flag on HTTPS.
Why form storage is used
The token expires after approximately one hour. If the form expires, reload the page and submit again. 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.
Saved game positions
Keep these details in mind. 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
The key details are straightforward. Keys beginning with spider-v1:stats- hold game statistics for the selected difficulty. Statistics can include started games, recorded wins and the best winning move count. These records stay in the current browser profile and domain. Clearing game data removes the statistics stored by this application.
Remembering choices
On this website, the following points apply. The spider-v1:preferences key stores the game-saving and sound choices. The site reads these choices when the game or settings page opens. 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.
When local records expire
On this website, the following points apply. The game records remain until the application, you or your browser removes them. Private browsing may discard records when its session ends. 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.
Manage or block storage
Here is what to know. Blocking the form cookie can prevent a contact submission from being accepted. 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.
External share services
Here is what to know. Activating a share link opens the selected service with the current page information. The built-in share buttons are links rather than embedded social-media widgets. An external service can apply its own cookie and storage practices on its destination page. The built-in application contains no advertising or analytics integration.
Questions about storage
The key details are straightforward. Contact [email protected] for a question about this website's storage practices. Clearing browser storage does not erase a message already saved on the server. 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.
