Privacy Policy

Welcome to ChessHelper.ai ("we," "our," or "us"). We are committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website at chesshelper.ai and our Chrome extension (collectively, the "Service").

By using our Service, you agree to the collection and use of information in accordance with this policy. If you do not agree with the terms of this Privacy Policy, please do not access or use the Service.

When you create an account, we may collect:

• Email address

Usage Data

We automatically collect certain information when you use the Service:

• Chess positions analyzed (FEN data)
• Number of analyses performed
• Browser type and version
• Device information
• IP address
• Pages visited and features used

We use the information we collect to:

• Provide, maintain, and improve the Service

We do not sell your personal information. We may share your data with:

• Analytics providers: Google Analytics collects anonymized usage data to help us understand how visitors use the Service
• Advertising partners: Google Ads may receive data for conversion tracking, remarketing, and ad personalization when you have consented to marketing cookies

We implement appropriate technical and organizational measures to protect your personal information, including encryption of data in transit and at rest, secure password hashing, and regular security assessments. However, no method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security.

We retain your personal information for as long as your account is active or as needed to provide you the Service. You may request deletion of your account and associated data at any time by contacting us at support@chesshelper.ai.

We use essential cookies to maintain your session and authentication state. We also use Google Analytics 4 (GA4) to collect anonymized usage data such as pages visited, traffic sources, and device information. Additionally, we use Google Ads cookies for conversion tracking and ad personalization.

You can manage your cookie preferences at any time using the cookie consent banner or by clicking "Cookie Settings" in the website footer. For full details on the cookies we use, please see our Cookie Policy.

Our Service integrates with third-party chess platforms (Chess.com and Lichess) through our Chrome extension. We do not access your credentials for these platforms. The extension only reads chess position data displayed on the page to provide analysis.

Depending on your location, you may have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Object to or restrict processing of your data
• Data portability
• Withdraw consent at any time

To exercise any of these rights, contact us at support@chesshelper.ai.

Our Service is not directed to individuals under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that a child under 13 has provided us with personal information, we will take steps to delete such information.

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date. Your continued use of the Service after any changes constitutes acceptance of the updated policy.
