Privacy Policy

Last updated: May 9, 2026

1. What we collect

When you create an account we collect your email address and a hashed password. When you use the Service we collect data about your learning activity — quiz answers, XP earned, streaks, and progress through courses — so we can personalize your experience.

If you subscribe to Pro, payment is processed by Stripe. We never store your full card number; Stripe provides us with a token and the last 4 digits.

2. Cookies and local storage

We use cookies and browser local storage to keep you logged in and remember your preferences (such as dark mode). We also use anonymous analytics cookies to understand how people navigate the site — these help us improve the product.

You can decline optional cookies via the banner at the bottom of the page. Essential cookies (authentication) are required for the Service to function.

3. How we use your data

To operate and personalize the Service
To send transactional emails (receipts, password resets)
To improve the Service through aggregate, anonymized analytics
To comply with legal obligations

We do not sell your personal data to third parties.

4. Data retention

We retain your account data as long as your account is active. If you delete your account, we will delete your personal data within 30 days, except where we are required by law to retain it longer.

5. Third-party services

We use the following third-party services that may process your data:

Supabase — database and authentication
Stripe — payment processing
Vercel — hosting and edge network

Each of these services has its own privacy policy governing their handling of your data.

6. Your rights

You have the right to access, correct, or delete your personal data. To exercise these rights, email us at hello@birdsbirdsbirds.net. We will respond within 30 days.
