Privacy Policy
Last updated: 12/2/2025
The Short Version
TL;DR: We don't collect, store, or share your personal data. Everything runs in your browser. Our Chrome extension only works on chess.com and doesn't track you. We're just here to experiment with chess tools!
Chess Experiments Website
What We Don't Collect
- Personal information (names, emails, addresses)
- Chess game data or moves
- User accounts or profiles
- Cookies for tracking
- Analytics or usage data
How It Works
Everything on chessexperiments.com runs entirely in your browser. Your chess games, engine analysis, and experimental features are processed locally on your device. Nothing is sent to our servers.
Third-Party Services
We use Ko-fi for donations (if you choose to support us). Ko-fi has their own privacy policy. We don't receive any personal information from Ko-fi donations.
Chess Experiments Chrome Extension
What It Does
- Adds experimental features to chess.com (like blindfold mode)
- Runs entirely in your browser
- Only activates on chess.com pages
What It Doesn't Do
- Collect or store your chess games
- Track your browsing
- Send data to external servers
- Access other websites
- Store personal information
Permissions
The extension only requests access to chess.com to add experimental features. It doesn't need or request access to other websites or your personal data.
Future Changes
If we ever decide to collect any data (which we don't plan to), we'll update this policy and let you know. But honestly, we're just here to experiment with chess tools for fun.
Questions?
If you have questions about privacy or anything else, feel free to reach out via our website.
The Bottom Line
We're just chess enthusiasts experimenting with fun tools. We don't want your data, we don't track you, and everything runs in your browser. Simple as that! 🏆
