Privacy Policy
Privacy Policy
Effective Date: June 2026
Welcome to Puzzle PK. Your privacy is critically important to us. This Privacy Policy explains how we collect, use, and protect your personal information when you use our website, games, and related services.
1. Information We Collect
We strive to collect only the absolute minimum amount of data required to operate the platform.
- Account Information: When you register, we collect a username and a securely hashed password. We do not require your real name or email address for basic gameplay.
- Gameplay Data: We store your high scores, game progress, match history, and unlocked achievements so you can track improvement over time.
- Technical Data: We temporarily log your IP address and connection timestamps solely for the purpose of maintaining server stability, preventing DDoS attacks, and ensuring fair play during real-time multiplayer matches (PK mode).
2. How We Use Your Information
- To provide, maintain, and improve our gaming platform.
- To manage your user account and authenticate your logins securely.
- To display global leaderboards and matchmaking rankings.
- To detect and prevent cheating, abuse, or other violations of our Terms of Service.
- To send you important service-related notifications (we do not send marketing emails).
3. Data Sharing and Disclosure
We do not sell, rent, or trade your personal information to third parties. Your data is strictly used for operating Puzzle PK. We may share anonymous, aggregated gameplay statistics (e.g., "10,000 matches of Sudoku played today") publicly, but this will never contain identifiable information.
4. Advertising & Google AdSense Cookies
To keep our games 100% free, Puzzle PK displays advertisements provided by Google AdSense and other third-party advertising networks.
How it works:
- Google AdSense uses cookies and similar tracking technologies to collect information about your visits to this and other websites in order to show you relevant advertisements.
- The DoubleClick cookie and other advertising cookies may be set by Google on your device when you visit our site. These cookies track which ads you have seen and allow Google to serve ads tailored to your interests.
- We do not have direct access to the data collected by these advertising cookies.
Your choices:
- You can opt out of personalised advertising by visiting Google's Ads Settings.
- You can also opt out via the Network Advertising Initiative opt-out page or manage cookies directly in your browser settings.
- Opting out does not remove ads entirely — it means ads will no longer be tailored to your interests.

6. Data Security
We implement industry-standard security measures, including bcrypt password hashing and SSL/TLS encryption for all data transmitted between your browser and our servers. However, no internet transmission is 100% secure, and we cannot guarantee absolute security.
7. Children's Privacy
Our games are designed to be enjoyed by users of all ages, including children. We do not knowingly collect personal information from children under 13 without parental consent. If you believe your child has provided personal information on our site, please contact us at [email protected] so we can promptly delete it.
