Privacy Policy

Last Updated: 2025-02-16

Who We Are

We are ChessQuant, a small team developing a web application that offers chess analytics and game insights. Our service is currently in a testing and development phase, so features and data handling practices may change.

Information We Collect

Google Sign-In Data: When you sign in with Google, we receive basic profile information (such as your email address, name, profile picture, and a unique Google identifier (sub)). We embed this data in a session token (JWT cookie) that keeps you logged in for up to 30 days. This token is periodically refreshed if you remain active. If you log out or remain inactive beyond this timeframe, the token expires and you’ll need to sign in again.

Waitlist Data: If your email address is not already on our approved list for access during our private beta, we will automatically add your email address to our waitlist. We store this so we can notify you when access becomes available. Your email address and any provided personal details are handled in accordance with this Privacy Policy.

Chess Game Data: ChessQuant may fetch and analyze publicly available chess games (e.g., from chess.com). We store these games in our database for caching, to reduce repetitive API calls, and to enable faster processing and search. Because these games are publicly accessible on third-party platforms, we do not treat them as private data.

How We Use Your Information

We use your Google profile data to authenticate you, display your name or avatar, and (if you opt in) to send any future email notifications or reports. We also use your email address for the waitlist process, meaning if you are not on our approved list, we may contact you once additional spots in our private beta become available.

We use chess game data to provide analytics, insights, and game search features. Over time, we may prune older or infrequently accessed games from our database, but we do not guarantee any specific retention period.

Data Security

We take reasonable steps to protect your information. However, no system is completely secure, especially while under active development. We will address any security concerns or vulnerabilities as soon as possible.

Data Sharing

We do not share your personal information with third parties unless it is necessary to provide our service (e.g., hosting or email providers) or required by law. If ChessQuant becomes involved in a merger or acquisition, we will inform you if your personal data is transferred or becomes subject to a different privacy policy.

Your Choices

You can stop using ChessQuant at any time. When your session token expires or you log out, we no longer hold your Google profile data in an active session. If you want to be removed from our waitlist or have concerns about how we handle your data, please contact us, and we’ll work with you to address them. However, note that publicly available chess games remain accessible on third-party platforms even if removed from our database.

Changes to This Policy

We may update this Privacy Policy as our service evolves. If we make significant changes, we will notify users (for example, by posting a notice on our site). Your continued use after any changes indicates acceptance of the updated policy.
