Privacy Policy
Last updated: October 17, 2026
Effective October 17, 2026. This notice describes the current portal and game implementation, including existing optional account APIs.
Browsing and preferences
The portal uses your browser’s language preferences to select a supported language. A manual language choice is carried in the page URL, without a language cookie or local storage. Games store settings such as audio levels and automatic attack in your browser. We have not added advertising or analytics trackers to this portal.
Optional accounts
You can sign in with Google from the portal and use the same account across all games. The server stores a protected reference to your verified Google identity, display name, internal account identifiers, creation time, and session and security information. It does not store your email address or Google ID token. Supported games can synchronize progress to your account in Firestore. Importing existing guest records requires your choice and preserves the original local copy. Conflicting records require a choice rather than an automatic merge.
Security and storage
Session cookies support authentication and request protection. The server uses connection IP addresses for request limiting; production limit records use hashed scopes instead of raw IP addresses. Production account, session and account-linked game progress records are stored in Google Cloud Firestore. Progress records contain game snapshots, internal owner/game identifiers, save versions and update times. Browser preferences, guest originals, account-specific local copies and synchronization recovery metadata remain in browser storage. Hosting infrastructure may keep operational logs under its configured retention policies.
Third-party services
Optional Google authentication communicates with Google and Firebase. GitHub Sponsors links open GitHub, where its own privacy policy applies. This portal does not receive payment-card details through those links. These providers may process information under their own policies.
Your choices and requests
You can clear site cookies and browser storage in your browser settings; this may remove preferences or local game records and end a session. To request access to or deletion of account information, email wonyoungchoiseoul@gmail.com. We may need to verify the account concerned before handling a request.
