Cookies and browser storage
The key details are straightforward. 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. 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 j5wan.com.
The contact-form cookie
The key details are straightforward. 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. The cookie contains a random value rather than your question or email address. The application marks this cookie HttpOnly and SameSite Strict, and uses the Secure flag on HTTPS.
Protecting a submission
On this website, the following points apply. The token expires after approximately one hour. The check helps reject requests that did not originate from the protected form flow. 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.
Local game keys
Keep these details in mind. A saved record includes the card layout and recent undo history so that play can resume. Game progress is stored under local-storage keys beginning with spider-v1:game-. Turning off game saving removes those application game records. One suit, two suits and four suits use separate saved game records.
Local statistics
Keep these details in mind. These records stay in the current browser profile and domain. Statistics can include started games, recorded wins and the best winning move count. Clearing game data removes the statistics stored by this application. Keys beginning with spider-v1:stats- hold game statistics for the selected difficulty.
Preferences storage
The key details are straightforward. The clear-data action switches saving and sound off after removing earlier records. The site reads these choices when the game or settings page opens. 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.
Duration of local storage
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
On this website, the following points apply. Blocking the form cookie can prevent a contact submission from being accepted. Your browser can also remove this domain's cookies and local storage. Privacy & Cookie Settings provides controls for this application's game records and preferences. Blocking local storage can stop progress from being retained between visits.
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. 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.
Contact and related information
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.
