Information pursuant to § 5 DDG (German Digital Services Act) and responsible for content pursuant to § 18 (2) MStV:
The controller responsible for data processing on this web application within the meaning of the GDPR is:
ChessCoach does not use cookies, analytics tools, user accounts, or persistent storage of personal user data.
The web service is hosted by Render Services, Inc. (525 Brannan St, Suite 300, San Francisco, CA 94107, USA). To deliver the website and process API requests technically, Render's infrastructure automatically processes connection metadata (in particular your IP address, timestamp, requested endpoint, and browser user agent) in temporary routing and security logs.
If you contact us by email, your email address and message content are processed solely to handle your inquiry (Art. 6(1)(b) or (f) GDPR) and are not shared with third parties.
Under the GDPR, you have the right to request access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20), and to object to processing based on legitimate interests (Art. 21), as well as the right to lodge a complaint with a data protection supervisory authority (Art. 77).
Note pursuant to Art. 11 GDPR: Because ChessCoach does not maintain user accounts or store personal identifiers, we are generally unable to link transient technical connection data (such as IP addresses in hosting logs) to an individual person. Rights under Art. 15–18 GDPR can therefore only be fulfilled to the extent that you provide additional information allowing clear identification (for example, in the context of direct email correspondence).
ChessCoach is a privately operated, free web application provided “as is” and “as available” without any warranties of any kind. There is no entitlement to continuous availability, error-free operation, or specific functionality.
All chess moves, evaluations, training recommendations, and analyses generated by ChessCoach are for informational and educational purposes only. No guarantee is given for the correctness, completeness, or optimal nature of any calculated move or strategic advice.
To the extent permitted by applicable law, the operator shall not be liable for any direct, indirect, incidental, or consequential damages resulting from the use or inability to use the ChessCoach web application. This limitation does not apply to liability for intent, gross negligence, or injury to life, body, or health.
Automated scraping, excessive API requests, or any activity intended to disrupt or overload the server infrastructure are prohibited. The operator reserves the right to restrict or block access at any time.
ChessCoach is proprietary software.
