Privacy Policy

1. Overview

Homeplate Metrics ("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.

2. Information We Collect

Authentication Data

Account creation and authentication are handled by Clerk (clerk.com). Clerk stores your email address, hashed password, and OAuth tokens (if you sign in via Google or Apple). We receive only a unique user identifier (userId) from Clerk — we do not store your password or OAuth tokens directly.

User-Generated Data

When you use authenticated features, we store the following in our database (Neon PostgreSQL):

• Bet records — game ID, bet amount, odds, prediction (NRFI/YRFI), outcome
• Bankroll data — starting balance, current balance, transaction ledger
• Watchlist items — games you have bookmarked
• User row — your Clerk userId and a placeholder email reference

Usage Data

We use Vercel Analytics (privacy-friendly, no cookies) to collect anonymous page view counts and performance metrics. No personally identifiable information is collected via analytics.

3. How We Use Your Data

• To provide and operate the Service (bet tracking, bankroll management, watchlist)
• To display your personal performance history and accuracy statistics
• To maintain your account across sessions
• To improve the Service based on aggregate usage patterns

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

4. Third-Party Services

We share limited data with the following third parties to operate the Service:

5. Cookies

Clerk uses cookies to maintain your authentication session. Vercel Analytics is cookieless. No advertising or tracking cookies are set by Homeplate Metrics. If you are in the EU/UK, you consent to session cookies by using the Service.

6. Data Retention

We retain your data for as long as your account is active. If you delete your account (via Clerk), we will delete your associated bet, bankroll, and watchlist records within 30 days. Aggregate model prediction data (not linked to your account) is retained indefinitely for backtesting purposes.

7. Your Rights

Depending on your jurisdiction, you may have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your account and data (right to be forgotten)
• Object to or restrict certain processing

To exercise these rights, contact us at contact@homeplatemetrics.com

8. Your Privacy Choices (CCPA/CPRA)

We do not sell or share your personal information for cross-context behavioral advertising, as those terms are defined under the California Consumer Privacy Act (CCPA), as amended by the California Privacy Rights Act (CPRA), or under similar state privacy laws.

If you are a California resident (or a resident of a state with a comparable privacy law), you have the right to know what personal information we collect, request its deletion, request correction of inaccurate information, and opt out of the sale or sharing of personal information — a mechanism that does not apply here because we do not sell or share your data. To exercise any of these rights, contact us at contact@homeplatemetrics.com. We will not discriminate against you for exercising these rights.

9. International Users & Data Transfers

Your data is processed and stored in the United States (Neon/Vercel infrastructure, as described in Section 4). If you access the Service from outside the United States, including from the EU/UK, you understand and consent to your information being transferred to and processed in the United States. We do not currently maintain a designated EU representative; if you have a GDPR-related request, contact us at contact@homeplatemetrics.com and we will respond as required by applicable law.

10. Data Security

We use industry-standard security measures including encrypted connections (TLS), server-side authentication (Clerk), and parameterized database queries (Prisma ORM). No system is 100% secure — please use a strong, unique password for your account.

11. Children's Privacy

The Service is not intended for users under 18. We do not knowingly collect personal information from anyone under 18. If you believe a minor has created an account, contact us and we will promptly delete it.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will update the effective date above and, for material changes, notify you via the Service.
