About this policy
Here is what to know. 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. This page explains the storage used by the built-in features of e-cac.com.
spider_csrf
The FAQ submission flow uses a cookie named spider_csrf to support request verification. 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 cookie is scoped to /api/ and expires after about one hour.
Why form storage is used
If the form expires, reload the page and submit again. The token expires after approximately one hour. 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.
Local game keys
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. Turning off game saving removes those application game records. Game progress is stored under local-storage keys beginning with spider-v1:game-.
Local statistics
Keep these details in mind. 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. These records stay in the current browser profile and domain.
Preferences storage
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. 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.
When local records expire
Keep these details in mind. Private browsing may discard records when its session ends. 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. The site cannot restore local progress after that browser data has been cleared.
Your browser choices
The key details are straightforward. 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.
External share services
On this website, the following points apply. 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. Activating a share link opens the selected service with the current page information. The built-in application contains no advertising or analytics integration.
Contact and related information
Here is what to know. 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. 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.
