Privacy Policy

1. General information

This website is an informational resource presenting the results of a chess analysis study. It does not require registration, does not collect personal data, and does not process any information that could be used to identify individual visitors.

2. Data collected automatically

Like most web servers, this site's hosting infrastructure may automatically record standard access log entries. These logs may contain:

• The IP address of the requesting client (processed in anonymised or hashed form by the application);
• The date and time of the request;
• The requested URL and HTTP method;
• The HTTP status code returned;
• The User-Agent string transmitted by the browser.

These records are used exclusively for operational purposes (diagnosing technical errors, preventing abuse, and rate-limiting automated requests) and are not shared with third parties for any commercial purpose. Server logs are retained only for the period necessary for operational purposes.

3. No personal data processing

No forms on this website request or store personal information such as names, email addresses, or payment details. The Matchup Lookup feature transmits only chess position identifiers to the server in order to retrieve pre-computed evaluation data; no personal information is involved in this process.

4. Rate limiting

To protect the service from automated abuse, the application records a one-way cryptographic hash (SHA-256) of the requesting IP address alongside a request counter. This hash cannot be reversed to obtain the original IP address and is deleted automatically once the relevant time window has expired. No IP addresses are stored in plain text by the application.

5. Third-party services

This website loads certain resources from third-party content delivery networks (CDNs), including but not limited to fonts and front-end libraries. When a browser loads these resources, it establishes a connection to the respective third-party server, which may log the visitor's IP address and browser information in accordance with that service's own privacy policy. The use of CDN resources is disclosed in the Cookie Policy section below.

6. User rights

Since no personal data is collected or stored by this website, there is no personal data subject to access, rectification, or erasure requests under applicable data protection legislation.

Cookie Policy

1. What is a cookie?

A cookie is a small text file that a website may store on a visitor's device. Cookies are widely used to make websites function efficiently and to provide information to the site's operators.

2. Cookies used by this website

This website uses only strictly necessary technical cookies. No tracking, profiling, or advertising cookies are set.

3. Third-party resources and potential tracking

This website loads fonts and front-end libraries from third-party CDNs (including Google Fonts and jsDelivr). When the browser fetches these resources, the third-party server receives the visitor's IP address and browser information. These services operate under their own privacy policies. No cookies are directly set by these third-party services as a result of loading resources on this site.

4. Cookie consent

Because only strictly necessary cookies are used — and no third-party tracking cookies are set — explicit cookie consent is not legally required under common interpretations of applicable regulations (e.g. the ePrivacy Directive and the GDPR). Visitors may, however, disable cookies through their browser settings. Disabling cookies may impair certain interactive features (such as the Matchup Lookup, which relies on session-based CSRF protection).
