What Are Cookies?

Cookies are small text files a website stores in your browser when you visit. They act as short-term memory — letting a site remember that you are logged in, what theme you prefer, and how you interact with its features.

Not all cookies are equal. Logic Arena draws a strict line between technically necessary cookies and optional analytics or third-party cookies.

Essential Cookies

Always active. We use exactly one essential cookie. It cannot be disabled without breaking authentication and security. No consent is required — it falls strictly under the necessary exemption.

Cookie NamePurposeLifespan

la_session

HttpOnly, Secure cookie containing your JWT (JSON Web Token). This is how the server knows you are logged in. It cannot be accessed by client-side JavaScript.

7 days (idle) / 30 days (remembered)

Analytics Cookies

Logic Arena loads Google Analytics using a lazy loading strategy so page rendering and gameplay are not blocked. Google Analytics may set cookies or use similar browser identifiers to measure page views, device/browser information, and aggregate usage patterns.

We use analytics to understand product usage and performance. We do not use analytics cookies to sell advertising profiles.

Cookie NamePurposeLifespan

_ga

Google Analytics identifier used to distinguish aggregate visits and usage patterns.

Up to 2 years

_ga_*

Google Analytics property-specific session and engagement measurement.

Up to 2 years

Local Storage (Not Cookies)

We use your browser's native `localStorage` for non-sensitive UI preferences. Theme values stay local. Auth uses the secure `la_session` cookie, not localStorage.

theme

Stores your chosen display theme (Cyberpunk, Light, Obsidian Ember) so it persists when you close the browser.

Third-Party Cookies

Logic Arena does not embed third-party advertising or social widgets. Third-party cookies may appear from Google Analytics and during OAuth 2.0 sign-in via Google or GitHub.

When you authenticate through OAuth providers, they may set their own cookies according to their own policies, which we do not control.

We recommend reviewing the cookie policies of Google and GitHub if you use OAuth sign-in.

Managing Preferences

You have full control over your session. You can clear your session cookie and local storage at any time through your browser's native settings.

Disable all cookies

You may block all cookies via browser settings. This will prevent login entirely, as we cannot authenticate you without the `la_session` cookie.

Log out

Clicking "Log out" in the application will instruct the server to immediately invalidate and delete your `la_session` cookie.

Policy Updates

We may update this Cookie Policy when we introduce new platform features that require new cookies, or when applicable regulations change. Updates will be reflected on this page with a revised date.
