1. What Are Cookies
Cookies are small text files placed on your device by a website. They allow the site to remember your preferences, keep you signed in, and understand how the site is being used.
OpeOpe.gg uses cookies for authentication, storing your UI preferences, and — only with your consent — measuring site traffic and performance.
2. How We Use Cookies
We group our cookies into three categories:
- Necessary — required for the site to function. These include authentication and your consent record. They are always active.
- Functional — improve your experience by remembering UI choices such as sidebar position or deck view mode. No consent required; no personal data is collected.
- Analytics (optional) — collect anonymised usage data to help us improve the site. These are disabled by default and only activated after you give consent.

| Vercel Speed Insights | Core Web Vitals and performance monitoring. | Yes — analytics |
5. Your Consent Choices
When you first visit OpeOpe.gg a cookie consent banner appears at the bottom of the screen. You can accept or decline optional analytics cookies at that point.
You can update your choice at any time on your Settings page. Changes take effect immediately — analytics scripts are loaded or unloaded without requiring a page refresh.
Declining analytics cookies has no effect on site functionality; all features remain available.
6. Changes to This Policy
We may update this policy to reflect changes in our cookie usage or applicable law. When we do, we will revise the effective date at the top of this page. Continued use of the site after an update constitutes acceptance of the revised policy.
