Privacy Policy
Last updated: 2026-04-24
brainiko.com ("we", "us", or "our") operates the brainiko.com website. This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our service.
Information We Collect
We collect minimal data to provide and improve our service. This includes: - Account data: email address, username, and display name when you register - Game data: scores, completion times, streaks, and game statistics - Usage data: pages visited, time spent, and browser type - Cookies for authentication and session management
Account & Authentication
When you create an account, we store your email address, username, and a securely hashed password. Your email is used for account verification and password reset. We use JWT (JSON Web Tokens) stored in your browser for authentication. You can play all games without an account — guest data is stored locally in your browser.
Email Communications
We send transactional emails for account verification and password reset using a third-party email service (Resend). We do not send marketing emails or newsletters. Your email address is never shared with third parties for promotional purposes.
Cookies
We use cookies for authentication (keeping you signed in) and session management. We also use analytics cookies to understand how the service is used. You can instruct your browser to refuse cookies, but some features (like signing in) require them.
Analytics
We use self-hosted analytics to monitor and improve the service. Analytics data is collected anonymously and is not shared with third parties.
Data Storage & Security
Account data and game scores are stored on our servers. Passwords are stored as secure hashes and cannot be read by us. Guest game progress is stored locally in your browser. You can delete your account and all associated data at any time from your profile settings.
Bot Protection
We use Cloudflare Turnstile to protect against automated abuse during registration. This service may collect limited technical data (IP address, browser characteristics) to verify that you are human. See Cloudflare's privacy policy for details.
Children's Privacy
Our service does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from anyone under the age of 13.
Changes to This Policy
We may update our privacy policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "last updated" date.
