This Cookie Policy explains what cookies are, how Weiqi ("we", "us", "our") uses them on our website and applications (collectively, the "Service"), and what choices you have. By using the Service, you agree to the use of cookies as described in this policy.

Last updated: January 2026.

1. What Are Cookies?

Cookies are small text files that websites store on your device when you visit them. They are widely used to make websites work efficiently and to provide information to site operators. Cookies may be set by us (first-party cookies) or by third-party services we rely on (third-party cookies).

2. Categories of Cookies We Use

We use only two categories of cookies: strictly necessary cookies, which are required for the Service to function, and analytics cookies, which help us understand how visitors use the Service so we can improve it.

3. Strictly Necessary Cookies

These cookies are essential for keeping you signed in, protecting the Service against abuse, and delivering core features such as content previews. They cannot be disabled in our systems. They are usually set in response to actions you take, such as signing in or filling out forms, and are removed when you close your session or sign out.

These cookies do not contain marketing profiles and are not shared with advertisers.

4. Analytics Cookies

We use a privacy-respecting analytics tool (Google Analytics 4) to measure traffic, page performance, and feature usage on our main site. The tool is only loaded when a measurement ID is configured for the production environment, and the data it collects is aggregated and does not directly identify you.

For a current and authoritative list of the cookies that this analytics provider may set, please refer to the provider's own documentation.

You can opt out of analytics tracking without affecting your ability to use the Service by installing your browser's built-in tracking protection, by enabling "Do Not Track" / "Global Privacy Control", or by using the opt-out mechanism published by the analytics provider.

5. What We Do Not Use

Weiqi does not use advertising cookies, retargeting pixels, social media tracking pixels, or cross-site behavioral profiling. We do not sell personal data.

6. How to Control Cookies

Most browsers allow you to refuse or delete cookies through their settings. The "Help" section of your browser typically explains how to do this. Please note that if you block strictly necessary cookies, parts of the Service (such as signing in) will not work.
