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 cstocoin.com. Local storage keeps data in the browser and is not automatically attached to each server request.
spider_csrf
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.
Why form storage is used
Here is what to know. 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 server checks the form cookie together with a signed token when a question is sent. The token expires after approximately one hour.
Local game keys
Keep these details in mind. Game progress is stored under local-storage keys beginning with spider-v1:game-. 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. One suit, two suits and four suits use separate saved game records.
Statistics keys
The key details are straightforward. These records stay in the current browser profile and domain. Statistics can include started games, recorded wins and the best winning move count. Keys beginning with spider-v1:stats- hold game statistics for the selected difficulty. Clearing game data removes the statistics stored by this application.
Preferences storage
Keep these details in mind. 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. Preference storage is used to remember your choices on later visits in the same browser.
When local records expire
The key details are straightforward. The game records remain until the application, you or your browser removes them. Private browsing may discard records when its session ends. 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.
Manage or block storage
Here is what to know. Blocking local storage can stop progress from being retained between visits. 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 the form cookie can prevent a contact submission from being accepted.
Storage on other websites
The key details are straightforward. Activating a share link opens the selected service with the current page information. The built-in application contains no advertising or analytics integration. 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.
Questions about storage
Keep these details in mind. The Privacy Policy describes contact submissions and technical request information in more detail. Contact [email protected] for a question about this website's storage practices. The operator should revise this policy whenever the storage used by the site changes. Clearing browser storage does not erase a message already saved on the server.
