Privacy Policy
Your privacy matters to us.
BrainFusion is designed to be privacy-friendly from the ground up. Learners join games without accounts, and we collect only what's necessary to provide the service.
Last updated: March 19, 2026
1. Information We Collect
When you create a BrainFusion account, we collect:
- Your email address (used for login and account communication)
- A password (stored securely using industry-standard hashing)
When you use the platform, we may also collect:
- Games and questions you create
- Session and gameplay data (scores, responses, timestamps)
- Basic usage analytics to improve the service
2. How We Use Your Information
We use your information solely to provide and improve BrainFusion. Specifically:
- To authenticate your account and maintain your session
- To deliver analytics and reports on gameplay performance
- To send important service updates (you can opt out of non-essential emails)
- To improve the platform based on aggregated usage patterns
We do not sell, rent, or share your personal information with third parties for marketing purposes.
3. Learner Privacy
BrainFusion is designed so that learners (students, trainees, participants) can join games without creating accounts. When learners play:
- They enter only a session code and a display name (first name or nickname)
- No email, password, or personally identifiable information is required
- Gameplay responses are tied to the session, not to a persistent identity
This privacy-by-design approach means learner data is minimal and not linked to any account.
4. Children's Privacy
BrainFusion does not knowingly collect personal information from children under 13. Since learners join games without accounts and provide only a display name, no personal data is collected from minors during gameplay.
Account creation (which requires an email address) is intended for educators, trainers, and adult users. If we become aware that a child under 13 has created an account, we will promptly delete it.
5. Security
We take reasonable precautions to protect your information, including:
- Passwords are hashed using bcrypt (never stored in plain text)
- All data transmitted over HTTPS encryption
- Regular security reviews of our codebase and infrastructure
No data transmission over the internet is entirely secure. While we strive to protect your information, we cannot guarantee absolute security.
