Privacy Policy

BJJ Study Hall ("we", "us", "our") is committed to protecting your privacy. This policy explains what information we collect, how we use it, and your rights regarding your data.

1. Information we collect

When you use BJJ Study Hall, we collect:

• Account information — your email address and password (stored securely via Supabase Auth)
• Profile information — your name, belt rank, and role (instructor or student) within your school
• School data — techniques, curricula, announcements, schedules, and other content you create
• Usage data — basic information about how you use the service (pages visited, features used)
• Payment information — billing is handled entirely by Stripe; we never store your card details

2. How we use your information

We use your information to:

• Provide and operate the BJJ Study Hall service
• Authenticate your account and keep it secure
• Process subscription payments through Stripe
• Send transactional emails (password resets, plan confirmations)
• Respond to support requests
• Improve the service over time

We do not sell your personal data. We do not use your data for advertising.

3. Data storage

Your data is stored securely using Supabase, which uses PostgreSQL databases hosted on AWS infrastructure. Data is protected with row-level security — school data is only accessible to members of that school.

4. Data sharing

We share your data only with the following third parties, and only to the extent necessary to operate the service:

• Supabase — database and authentication provider
• Stripe — payment processing (they receive your billing info; we do not)
• Netlify — website hosting

We do not share your data with any other third parties without your consent.

5. Cookies

BJJ Study Hall uses only essential cookies required for authentication and session management. We do not use tracking or advertising cookies.

6. Your rights

You have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your account and associated data
• Export your data

To exercise any of these rights, email us at bjjstudyhall@gmail.com.

7. Data retention

We retain your data for as long as your account is active. If you delete your account, we will remove your personal data within 30 days, except where we are required to retain it for legal or financial compliance reasons.

8. Children's privacy

BJJ Study Hall is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with their information, please contact us and we will delete it.

9. Security

We take reasonable measures to protect your data, including encrypted connections (HTTPS), secure password hashing, and row-level database security. No system is perfectly secure, and we cannot guarantee absolute security.

10. Changes to this policy

We may update this privacy policy from time to time. We will notify users of significant changes by email. Continued use of the service after changes constitutes acceptance of the updated policy.
