Privacy Policy

Introduction

Happy Brain Games ("we", "our", or "us") operates the website happybrain.games and related game services. We are committed to protecting your privacy and being transparent about how we handle your data.

This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using our services, you agree to the practices described in this policy.

Information We Collect

Account Information

When you create an account, we may collect:

• Username
• Email address
• Profile information (display name, avatar)

Social Login Data

If you sign in through a third-party provider (Google, Discord, Facebook, or similar), we receive limited profile information such as your name, email address, and profile picture URL. We do not receive or store your social media password. All social account identifiers are encrypted at rest using AES-256-GCM encryption.

Game Data

We collect gameplay information to provide our services, including:

• Puzzle completion times and scores
• Game progress and statistics
• Achievements and streaks
• Leaderboard rankings

Device & Usage Data

We automatically collect certain technical information:

• Device type and screen size
• Browser type and version
• Anonymous session identifiers
• General usage patterns (pages visited, features used)

We do not collect precise geolocation. Device and usage data listed above is used solely for service operation and is never combined to track you across other sites.

How We Use Your Information

We use the information we collect to:

• Provide, maintain, and improve our games and services
• Authenticate your identity and manage your account
• Enable social features like friends lists and leaderboards
• Send transactional emails (e.g., verification codes, password resets)
• Respond to bug reports and support requests
• Analyze usage trends to improve the player experience
• Detect and prevent fraud, abuse, or security incidents

We do not sell your personal information to third parties. We do not serve advertising. We do not use your data for purposes unrelated to providing our services.

Cookies & Local Storage

We use essential cookies and browser local storage to keep you signed in, remember your preferences, and protect against cross-site request forgery (CSRF). Optional analytics cookies are used only if you accept them. We do not use advertising cookies.

Data Sharing & Third Parties

We may share limited data with the following categories of service providers:

• Email delivery: We use Mailjet to send transactional emails (verification codes, notifications). Your email address is shared with Mailjet solely for delivery purposes.
• OAuth providers: When you link a social account, authentication data flows through the provider (Google, Discord, Facebook, etc.) under their respective privacy policies.
• Infrastructure: Our services are hosted on secure servers. We do not share your data with hosting providers beyond what is necessary for operation.
• Analytics and diagnostics: If you accept analytics cookies, we use Google Analytics and Google Tag Manager to understand aggregate product usage. We also send limited diagnostics, performance metrics, and accessibility preference signals to Happy Brain Games to improve reliability and usability. These reports are not used for advertising.

We will never sell, rent, or trade your personal information. We may disclose data if required by law or to protect the rights and safety of our users.

Data Security

We take the security of your data seriously and implement industry-standard protections, including:

• All connections are encrypted with TLS (HTTPS)
• Passwords are hashed using Argon2id (never stored in plaintext)
• Social account data is encrypted at rest with AES-256-GCM
• Authentication tokens are short-lived with secure refresh mechanisms
• Rate limiting and brute-force protection on all authentication endpoints

No system is 100% secure, but we continuously work to protect your data and promptly address any security concerns.

Data Retention

We retain your account data for as long as your account is active. Game statistics and leaderboard data are retained to maintain historical records. If you delete your account, we will remove your personal information within 30 days, though anonymized aggregate data may be retained.

Your Rights

You have the right to:

• Access your personal data — view your profile and connected accounts at any time
• Correct inaccurate information — update your username or email in your profile settings
• Delete your account — contact us to request full account deletion
• Disconnect social accounts — unlink any connected social login from your profile page
• Export your data — request a copy of your personal data by contacting us

Children's Privacy

You must be at least 13 years old to use our services. We do not knowingly collect personal information from children under 13. If we become aware that we have collected data from a child under 13, we will take steps to delete that information promptly. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at hello@happybrain.games.

Changes to This Policy

We may update this Privacy Policy from time to time. When we make significant changes, we will notify users through our services. Your continued use of our services after any changes constitutes acceptance of the updated policy.
