ChessZing.com ("we") is an online Chinese Chess (Xiangqi) site. This page explains what data we collect and why.

What we collect

Account data: if you create an account we store your email address, a salted password hash (or your Google account identifier when you sign in with Google), your credit balance and a log of credit changes.
Game data: moves of online games, results and ratings, tied to a random device identifier stored in your browser.
Payments: purchases are processed by Stripe. We never see or store your card details; we keep the Stripe session id and the number of credits purchased.
Usage analytics: we use Google Analytics 4 to understand which features are used (pages viewed, games started, puzzles solved). IP addresses are anonymised by Google Analytics.
Preferences: theme, language and sound settings are kept in your browser's local storage.

Sign in with Google

When you choose "Continue with Google" we request only your email address and basic profile identifier (the openid and email scopes). We use them solely to create or find your ChessZing account. We do not access your contacts, calendar, Drive or any other Google data.

How we use data

To run the game, keep your credit balance, show leaderboards, prevent abuse and improve the site. We do not sell personal data and do not show third-party advertising.

Retention and deletion

You can delete your account and all associated data at any time by emailing hello@chesszing.com from the account's email address. We respond within 7 days.
