About this policy
Keep these details in mind. This page explains the storage used by the built-in features of 87dailian.com. Local storage keeps data in the browser and is not automatically attached to each server request. 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.
spider_csrf
Keep these details in mind. 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. The cookie is scoped to /api/ and expires after about one hour.
Why form storage is used
Keep these details in mind. 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 token expires after approximately one hour. The check helps reject requests that did not originate from the protected form flow.
Saved game positions
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.
Statistics keys
Keep these details in mind. These records stay in the current browser profile and domain. Clearing game data removes the statistics stored by this application. 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.
Preferences storage
Keep these details in mind. 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 spider-v1:preferences key stores the game-saving and sound choices. The clear-data action switches saving and sound off after removing earlier records.
When local records expire
Keep these details in mind. 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.
Your browser choices
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. Blocking local storage can stop progress from being retained between visits. Your browser can also remove this domain's cookies and local storage.
External share services
Keep these details in mind. 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. 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.
Contact and related information
On this website, the following points apply. 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 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.
