We take your privacy seriously. This Privacy Policy ("Policy") explains what information The Quiz Consortium, the operator of Quiz Brain ("we", "us", or "our"), collects when you use quiz-brain.com (the "website" or "service"), how we use it, who we share it with, and the choices you have. By using the service, you agree to the practices described here.
If you do not agree with this Policy, please do not use the service.
Information we collect
We try to collect only what we need to run the service:
- Email address — when you sign in. We use passwordless "magic link" sign-in, so your email is used to send you a secure login link and to identify your account.
- Account and gameplay data — a display name you choose, plus the quiz results, scores, and progress we save to your account.
- IP address — collected automatically and used for security and abuse prevention.
- Usage and analytics data — basic information about how you interact with the site, gathered through analytics tools.
How we use your information
- Email: to send sign-in links and contact you about your account.
- Account and gameplay data: to save your progress, show your scores, and power features such as leaderboards.
- IP address: security and fraud prevention.
- Analytics: to understand usage and improve the experience.
Leaderboards and public information
If you choose to take part in a leaderboard, the display name you pick and your associated quiz scores may be visible to other users. Please avoid using your real name or any detail you would not want shown publicly — you can change or hide your display name at any time in your account settings.
How your information is shared
We do not sell your personal information. We share data only with the service providers that help us run the website, and only as needed to provide the service:
- Supabase — our authentication and database provider, which stores your account, sign-in, and gameplay data on our behalf.
- Analytics providers — to measure traffic and usage.
- Advertising partners — which may set cookies to show and measure ads.
- Internal cookies — to keep you signed in, remember your progress, and record your consent choices.
Access and deletion
You can ask what personal information we hold about you and, in most cases, request a copy. You can also ask us to delete your account and its associated data. Before acting on a request we may need to verify your identity. We may retain certain information where we have a legal obligation, need to resolve disputes or enforce our agreements, or for legitimate security and technical reasons such as preserving the integrity of our systems.
Your GDPR rights (EEA users)
If you are in the European Economic Area, you have rights to access, correct, delete, restrict, or object to our processing of your personal data, as well as a right to data portability. To exercise any of these, contact us using the details below — we may ask you to confirm your identity first. You also have the right to lodge a complaint with your local data protection authority.
Your CCPA rights (California users) — do not sell my personal information
We do not sell your personal information for money. That said, some advertising and analytics technologies may count as a "sale" or "sharing" of personal information under California law. If you would like to opt out of the use of your information for interest-based advertising, contact us or use any opt-out controls we provide, and we will honor your request.
Children
The service is intended for a general audience and is not directed to children under 13, and we do not knowingly collect personal information from them.
Data retention
We keep your information for as long as your account is active or as needed to provide the service, and afterward only as long as necessary to meet our legal obligations, resolve disputes, and enforce our agreements.
Changes to this Policy
We may update this Policy from time to time. When we make material changes, we will revise the "last updated" date below.
