About this policy
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 shdnsw.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
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 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.
Why form storage is used
The key details are straightforward. If the form expires, reload the page and submit again. The check helps reject requests that did not originate from the protected form flow. The token expires after approximately one hour. The server checks the form cookie together with a signed token when a question is sent.
Saved game positions
On this website, the following points apply. A saved record includes the card layout and recent undo history so that play can resume. One suit, two suits and four suits use separate saved game records. Game progress is stored under local-storage keys beginning with spider-v1:game-. Turning off game saving removes those application game records.
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
Here is what to know. 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. 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.
Duration of local storage
Here is what to know. The site cannot restore local progress after that browser data has been cleared. 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. Private browsing may discard records when its session ends.
Your browser choices
Privacy & Cookie Settings provides controls for this application's game records and preferences. Blocking local storage can stop progress from being retained between visits. 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
Here is what to know. 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
The key details are straightforward. 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.
