ChessHints.com ("we," "us," or "our") operates https://chesshints.com (the "Site"). This Privacy Policy explains how we collect, use, disclose, and protect information when you analyze chess positions, solve puzzles, play games, create an account, or read educational content.
We are committed to protecting your privacy. This Policy applies to all visitors and users of the Site. By using the Site, you agree to the collection and use of information in accordance with this Policy.
You can use the analyzer, puzzles, and games without creating an account. If you sign in, we collect the information needed to provide account features and save your progress.
When you visit the Site, we may automatically collect certain information about your device and usage, including:
This information is collected through server logs and may include the use of cookies or similar technologies for site functionality and analytics.
If you create or connect an account, we may receive and store your email address, display name, profile image, authentication provider, provider account identifier, and email-verification status. Social sign-in providers may also process information under their own privacy policies.
Your display name, profile image, level, XP, puzzle totals, streaks, badges, game totals, and rating may appear on public profile and leaderboard pages. Your email address and authentication details are not displayed publicly.
For signed-in users, we may store puzzle attempts and solves, hints used, completion time, XP, levels, streaks, achievements, multiplayer game results, and rating data. For guests, puzzle progress and preferences may be stored only in the browser using local storage. Shared multiplayer games and abuse-prevention records may be stored on our server even when no account is used.
Chess positions and moves are processed to provide analysis and gameplay. Stockfish analysis normally runs in your browser. A position included in a shareable URL may be visible to anyone who receives that URL.
If you contact us, we may retain your name, email address, message, and related correspondence so we can respond and prevent abuse.
The Site uses Stockfish (an open-source chess engine) for browser-based analysis and AI gameplay. We may use Google and Facebook for social sign-in, Google Analytics for usage measurement, Google AdSense for advertising on selected pages, GTranslate for translation, and a hosting provider to deliver the Site and store data. These providers process data under their own terms and privacy policies.
For information about Google's processing, see Google's Privacy Policy. For Facebook, see Meta's Privacy Policy.
We use collected information for the following purposes:
We do not sell, rent, or share your personal information with third parties for marketing purposes.
The Site uses cookies and browser storage for essential functions, preferences, saved guest progress, authentication, analytics, and—on selected pages—advertising.
You can manage cookies through your browser settings. Disabling cookies may affect Site functionality.
We do not share personal information with third parties except:
Anonymous, aggregated data may be shared for analytical purposes.
We implement reasonable technical and organizational measures to protect your information from unauthorized access, loss, or misuse. However, no online transmission or storage is completely secure.
Account and progress data is generally retained while the account remains active or as needed to provide the service. Shared game records, security records, server logs, analytics data, and correspondence are retained only as long as reasonably necessary for their purpose, legal obligations, dispute resolution, or abuse prevention. Guest browser data remains until you clear your browser storage. You may request deletion of your account data using the contact information below.
If you are in the European Union, UK, or California, you may have rights regarding your personal data, including:
To exercise these rights, request account deletion, or ask a privacy question, contact us at contact[@]chesshints[,]com. We may need to verify your identity before fulfilling a request.
We do not collect data from children under 13 (or relevant age in your jurisdiction) without parental consent.
Our service providers may process information in countries other than your own. Where required, we use appropriate safeguards for international transfers.
The Site may link to external sites (e.g., Stockfish documentation). We are not responsible for their privacy practices.
We may update this Policy periodically. Changes will be posted here with an updated "Last Updated" date. Significant changes will be highlighted on the Site.
