Privacy Policy

Last updated: November 2025

JD Chess (“we”, “us”, “our”) provides online chess coaching and educational content through our websites jdchess.com, jdchess.us, and our associated mobile application.
This Privacy Policy explains how we collect, use, and protect your personal information.

1. Data Controller

JD Chess is operated by Jean-Dominique Casanova, individual sole trader based in Europe (Warsaw, Poland).
For any privacy-related request, please contact: [email protected]

2. Information We Collect

We collect and process personal information that you provide directly to us, including:

  • Booking information: name, email address, timezone, and lesson preferences.
  • Account data: usernames, login details, and course progress (for academie.jdchess.com or related platforms).
  • Payment details: handled securely by external payment processors; we do not store card numbers.
  • Communication data: messages exchanged by email or forms.
  • Analytics data: non-identifiable usage statistics to improve our website.

We do not knowingly collect sensitive personal information.

3. How We Use the Data

We use your data to:

  • Schedule and deliver chess lessons.
  • Manage your account and communicate with you.
  • Improve our services and user experience.
  • Comply with legal obligations.

We do not sell, rent, or share your personal information with any third party.

4. Data Storage and Security

All student and account data are stored on self-hosted, secured databases managed by JD Chess.
Transactional and booking-related emails are sent through Resend.com, an external email delivery service that processes messages solely for communication purposes on our behalf.
We take reasonable technical and organizational measures to prevent unauthorized access, loss, or alteration of your data.

5. Cookies

Our websites currently do not use cookies or tracking pixels.
However, this may change in the future to improve functionality or analytics.
If cookies are introduced, we will update this policy accordingly and, where required, request your consent.
Some external services we link to (such as payment or booking providers) may already set their own cookies; their policies apply independently.

6. Data Retention

We retain personal information only as long as necessary to provide our coaching services or comply with legal requirements.
When data are no longer needed, they are securely deleted or anonymized.

7. Students Under 18

We welcome students under 18 years old with the consent and supervision of a parent or legal guardian.
We do not knowingly collect personal data from minors without parental authorization.

8. Your Rights

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

  • Access, correct, or delete your data.
  • Withdraw consent at any time.
  • Request a copy of your personal information.
  • File a complaint with a data-protection authority.

To exercise these rights, contact [email protected].

For users in the European Union, we process personal data under the GDPR on the following bases:

  • Performance of a contract (providing lessons or accounts).
  • Legitimate interest (service improvement).
  • Legal obligation (record-keeping).

For U.S. visitors, this policy aligns with CCPA principles.

10. International Data Transfers

Your data may be processed in the European Union and other jurisdictions where JD Chess or its service providers (including Resend.com) operate.
We ensure equivalent protection standards consistent with GDPR.

11. Mobile Application

The JD Chess mobile app allows users to access the booking calendar and related website features from their mobile device.
The app does not collect any additional personal data beyond what is necessary to create and confirm lesson bookings (such as name, email, and selected time slot).
It does not display or synchronize full student schedules.
All data are processed and stored securely on the same self-hosted systems as our website.
We do not use in-app analytics, push notifications, or tracking technologies.

12. Changes to This Policy

We may update this Privacy Policy from time to time.
The latest version will always be available at jdchess.com/privacy.
