How CoolMathsZone handles accounts, saved progress, analytics, and guest play.
Plain-language summary
Lessons remain free to access whether you are logged in or using the site as a guest. If you create an account, we store profile and progress data so your coins, skins, streaks, and saved gameplay can persist across sessions. If you stay as a guest, some lesson unlocks and cosmetic selections may be stored only in your browser on that device.

1. Introduction
CoolMathsZone ("we", "our", or "us") operates coolmathszone.com (the "Service"). This policy explains what information we collect, how we use it, and what choices you have when using the Service.
We aim to collect as little personal information as we reasonably can while still supporting free lessons, optional accounts, saved progress, and interactive games.
2. Information We Collect
2.1 Information You Provide
Account Information: If you sign in or register, we may process your email address and any username or profile details attached to your account.
Contact Information: If you contact us through the contact form, we process the information you submit so we can respond.
Profile Preferences: For signed-in users, we store selected skins and unlocked assets so they persist across sessions.
2.2 Information We Generate During Use
Game and Lesson Progress: Scores, coins, XP, streaks, unlocked skins, and related gameplay/profile progress for signed-in users.
Lesson Completion Data: Completion of certain lesson topics may unlock cosmetic skins for logged-in users, and may be stored locally for guests.
Analytics and Usage Data: Page views, session behavior, and feature usage to understand how people use the Service.
2.3 Device and Browser Data
Technical Information: IP address, browser type, device information, and operating system.
Local Browser Storage: For guest users, certain unlocks and equipped skins may be stored in your browser on that device.
Cookies and Similar Technologies: We use cookies or similar technologies for authentication, security, analytics, and essential site features.
3. How We Use Information
To provide free lessons, games, and educational content.
To authenticate users and maintain optional accounts.
To save coins, skins, streaks, scores, and other profile progress for signed-in users.
To store guest unlocks and cosmetic preferences locally in the browser when no account is used.
To improve site performance, content quality, and gameplay experience.
To monitor usage, diagnose technical issues, and protect the Service against abuse.
To respond to support requests or messages you send us.
4. Accounts, Guests, and Saved Progress
4.1 Logged-in Users
If you create or use an account, we may store the following so your experience persists across visits:
Username and email address
Math coins and XP
Unlocked skins and active skin selection
Daily streak information
Saved gameplay-related profile information
4.2 Guest Users
You can still access lessons without logging in. When using the Service as a guest:
Lesson access remains free and available.
Some lesson-based skin unlocks and equipped cosmetic selections may be stored only in local browser storage on your device.
Guest progress stored locally may be lost if you clear browser storage, use a different browser, or switch devices.
5. Children's Privacy
CoolMathsZone is designed for educational use, including by children. We try to limit the personal information we collect and support guest lesson access without requiring an account.
If you are a parent or guardian and believe a child has provided personal information through the Service that should be reviewed or removed, please contact us. We will review the request and respond as appropriate.
6. Data Security
Encryption of data in transit through HTTPS/TLS
Use of managed infrastructure and authentication providers
Access controls for systems we manage
Reasonable technical steps to reduce unauthorized access risk
No system can guarantee absolute security, but we work to protect the data we hold.
7. Data Retention
Account-related information is generally retained while the account remains active, unless deletion is requested.
Gameplay and profile progress linked to an account may be retained so the Service continues to function for that user.
Guest unlocks stored in the browser remain until they are cleared by the user or overwritten.
Analytics data may be retained according to the settings of the analytics providers we use.
8. Third-Party Services
Supabase: Authentication, account sessions, and profile-related data storage
Google Analytics: Site analytics and usage measurement
Google AdSense: Advertising services
Netlify: Hosting and delivery infrastructure
These providers may process information on our behalf according to their own terms and privacy practices.
9. Your Choices
Use as Guest: You can access lessons without creating an account.
Sign Out: You can stop using a signed-in session at any time.
Browser Storage: You can clear locally stored guest unlocks through your browser settings.
Contact Us: You can contact us about account, privacy, or deletion requests.
