1. Overview

GrindLab ("we", "us", "our") respects your privacy. This policy explains what data we collect, how we use it, and your rights.

2. Data We Collect

Account data: When you sign in with Google or Discord, we receive your name, email address, and profile picture. We do not store your password — authentication is handled entirely by Google/Discord.

Usage data: We collect anonymous analytics (page views, feature usage) via Vercel Analytics to improve the product. No personally identifiable information is included.

Analysis data: Your saved spots, ranges, and hand analyses are stored in our database and associated with your account.

To improve GrindLab based on aggregate usage patterns

4. Data Sharing

We do not sell, trade, or share your personal data with third parties. Your ranges, analyses, and study history are private by default. Shared analysis links only expose the specific spot you choose to share.

5. Data Storage & Security

Your data is stored on Supabase (PostgreSQL) with encryption at rest and in transit. We use industry-standard security practices to protect your information.

6. Cookies

GrindLab uses essential cookies for authentication and session management. We use Vercel Analytics which does not use cookies and does not track individual users across sites.

7. Your Rights

You can request access to, correction of, or deletion of your personal data at any time by contacting us. If you delete your account, all associated data will be permanently removed.

8. Children

GrindLab is not intended for users under 18 years of age. We do not knowingly collect data from minors.
