This policy explains how we collect, use, store, and share data—especially when you sign in with Google or interact with Google services—to comply with the Google API Services User Data Policy and related terms.

Data We Collect

When you use the site or the optional sign‑in feature, we may collect:

• Account data (via Google Sign‑In): UID, displayName, photoURL, and email provided by Google. We do not collect your password.
• On‑site interaction data: your favorites, likes, ratings, and the associated game identifier (such as page slug).
• Usage and device information: page views, time on page, interaction events, device and browser info, coarse location inferred by analytics/ad platforms.
• Cookie and similar technology data: used to remember preferences, perform analytics, support advertising, and prevent abuse.

How We Use Data

• Authentication: verify identity via Google Sign‑In, show your nickname and avatar, and keep your session active.
• Features and personalization: store and sync your favorites, likes, and ratings across sessions.
• Analytics and improvement: use analytics data (Google Analytics, Yandex Metrika, Microsoft Clarity) to understand usage and improve experience and performance.
• Advertising and business support: use Google AdSense and/or Ezoic 以维持网站运营（见“Sharing and Third Parties”）。
• Security and compliance: detect and prevent fraud, abuse, and violations; respond to lawful requests by authorities.

Google Sign‑In and Limited Use

• Login method: we use Firebase Authentication’s GoogleAuthProvider (OAuth2) and request basic profile and email solely to provide sign‑in and site features.
• Limited Use: Google‑derived user data is used only to provide user‑facing features, improve the service, and ensure security. We do not sell data.
• Sharing restrictions: we do not transfer Google user data to third parties for independent marketing or ad targeting; limited sharing may occur with processors strictly to operate or maintain our service.
• Revoke access: you can revoke Mokiru’s access anytime at Google Account permissions.

Storage and Retention

• Locations: account interaction data (favorites, likes, ratings) is stored in Firebase Firestore under user namespaces such as users/{uid}/favorites, users/{uid}/likes, and users/{uid}/ratings. Short‑term session state is stored in browser sessionStorage.
• Retention: account interaction data is retained while your account remains active. If you revoke access or request deletion, we will delete or anonymize your related records.
• Security: we apply access controls, data minimization, and transport encryption to reduce the risk of unauthorized access.
