1. Who We Are
C4Chess ("we") is the controller of the personal data processed through this platform. For privacy questions or to exercise your rights, contact privacy@c4chess.com. [Where required, C4Chess's data protection officer / EU or UK representative contact details go here.]
2. Information We Collect
Account data (email, public user ID, password credentials), date of birth for age verification, and, for minors, a record of parental consent.
Usage and gameplay data (games played, ratings, progress, feedback), device and log data, and any information you provide when booking demos or contacting us.
3. How We Use Data & Legal Bases
We use personal data to provide and secure the service, personalize learning, process payments, and communicate with you. Where the GDPR/UK GDPR applies, our legal bases are: performance of a contract; your consent (which you may withdraw at any time); our legitimate interests in operating and improving the service; and compliance with legal obligations.
4. Children's Privacy
We take extra care with children's data. Accounts for children under 13 must be created by a parent or guardian, and users aged 13–17 require parental consent. Parents and guardians may review, correct, or delete their child's data, and withdraw consent, by contacting privacy@c4chess.com. We collect the minimum data necessary and do not knowingly sell children's data or use it for targeted advertising.
5. Cookies & Similar Technologies
We use essential cookies to keep the platform secure and working, and — with your consent where required — optional cookies to understand usage and improve the experience. You can manage optional cookies via the cookie banner or your browser settings.
6. How We Share Data
We share data with service providers (processors) that host our infrastructure, authenticate users, and process payments, under contracts that require them to protect your data. We do not sell your personal data. We may disclose data where required by law or to protect users' safety.
7. International Data Transfers
As a global service, your data may be processed in countries other than your own. Where personal data is transferred internationally, we use appropriate safeguards (such as Standard Contractual Clauses) as required by applicable law.
8. Data Retention
We keep personal data only as long as needed to provide the service and meet legal obligations, after which it is deleted or anonymized. You can request deletion at any time (subject to legal retention requirements).
9. Your Rights
Depending on where you live, you may have the right to access, correct, delete, restrict, or object to processing of your data; to data portability; and to withdraw consent. These rights are provided under the EU/UK GDPR, the U.S. state laws (including California's CCPA/CPRA right to know, delete, correct, and opt out, with non-discrimination), India's DPDP Act, Brazil's LGPD, and other applicable laws.
To exercise any right, contact privacy@c4chess.com. You also have the right to lodge a complaint with your local data-protection authority.
10. Security
We use technical and organizational measures to protect personal data. No system is perfectly secure, but we work to safeguard your information and will notify you and regulators of a breach where the law requires.
11. Changes & Contact
We may update this Privacy Policy; the "Last updated" date reflects the current version, and we will seek renewed consent where required. Contact us at privacy@c4chess.com. Website: www.c4chess.com.
