Privacy Policy

Blindfold Chess ("the Site") respects user privacy and is committed to protecting personal information. This Privacy Policy explains how the Site collects, uses, and protects information.

Use of Cookies

The Site uses cookies to keep your session and preferences, and — only if you agree — to measure how the site is used. Cookies are small text files stored on your device by websites. While you can disable cookies, some features may not function properly.

Use of Google Analytics

The Site uses Google Analytics to understand site usage and improve services. Google Analytics uses cookies to collect the following information:

• Access statistics such as visitor count and page views
• Behavior patterns and time spent on the site
• Device and browser information

Data collected by Google Analytics is managed according to Google's Privacy Policy. For details, please see: Google Privacy Policy

Google Analytics is only loaded after you agree through the cookie banner. If you decline, it is never loaded and no analytics cookies are set. You can change your choice at any time from “Cookie settings” in the footer.

Advertising

The Site serves its own advertising and affiliate placements. Which one appears is decided by the page it appears on, not by anything known about you: no third-party advertising network runs on this site, no profile is built, and no advertising cookies are set. Following an affiliate link may pass an identifier for the placement to the merchant's affiliate network so that the click can be credited.

For details on affiliate links, please see: Affiliate Disclosure

The Site uses browser local storage for the following purposes:

• Saving game progress and user settings
• Remembering theme settings (dark mode/light mode)

Collection of Personal Information
