Cookies and browser storage
This page explains the storage used by the built-in features of 1515ip.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. Local storage keeps data in the browser and is not automatically attached to each server request.
spider_csrf
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. 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
Here is what to know. 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
Here is what to know. 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. A saved record includes the card layout and recent undo history so that play can resume.
Local statistics
On this website, the following points apply. Statistics can include started games, recorded wins and the best winning move count. 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.
Preferences storage
On this website, the following points apply. The clear-data action switches saving and sound off after removing earlier records. 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 site reads these choices when the game or settings page opens.
Duration of local storage
On this website, the following points apply. 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
Keep these details in mind. 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 the form cookie can prevent a contact submission from being accepted. Blocking local storage can stop progress from being retained between visits.
Storage on other websites
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. An external service can apply its own cookie and storage practices on its destination page.
Contact and related information
On this website, the following points apply. 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. Contact [email protected] for a question about this website's storage practices.
