During the current beta, we do not use Stripe or payment-related cookies.
Cookies are small text files stored on your device when you visit a website. We also use local storage, session storage, and similar browser technologies. This policy explains how Ai.Libi uses them on https://www.ai-libi.com.
On your first visit, we show a cookie banner. Essential cookies load immediately because the game cannot function without them. Analytics cookies—including browser-side Sentry error monitoring—load only if you choose "Accept All" or enable Analytics in custom preferences. You can change your choice anytime via the cookie icon on the site.
Required for authentication, guest sessions, game rooms, and security. These cannot be disabled while using the Service.
Help us diagnose crashes and improve performance. Browser Sentry, Vercel Web Analytics, and Speed Insights load only if you accept Analytics cookies (or choose Accept All).
Remember language, theme, in-game UI state, and onboarding progress.
We do not currently use advertising or retargeting cookies. If that changes, we will update this policy and request consent where required.
