Privacy Policy

Last updated: July 6, 2026

This Privacy Policy explains how Fourth & AI(“we”, “us”) collects, uses, and protects your information when you use fourthandai.com(the “Service”). By using the Service, you agree to this Policy.

1. Information we collect

Account information — your email address and login credentials (authentication is handled by Supabase).
Connected league data — when you link a fantasy platform (e.g. Sleeper or ESPN), we retrieve and store your league, roster, and team information to power the Service.
Payment information — subscriptions are processed by Stripe. We do not store your card details; Stripe handles them and shares limited billing status with us.
Usage data — basic analytics such as pages visited and general device information, to understand and improve the Service.
Content you submit — questions you ask the AI assistant and choices you make in the app.

2. How we use your information

to provide, operate, and improve the Service;
to generate projections, recommendations, and AI-written analysis for your team;
to process payments and manage your subscription;
to communicate with you about your account or the Service; and
to secure the Service and comply with legal obligations.

3. Service providers we share data with

We share information only as needed with providers who help us run the Service, under their own privacy terms:

Supabase — database and authentication.
Stripe — payment processing and subscription billing.
Anthropic — AI model that generates written analysis (from the prompts and stats we send).
Vercel — hosting and, if enabled, privacy-friendly analytics.
Fantasy platforms — Sleeper, ESPN, and others you choose to connect.

We do not sell your personal information.

4. Cookies

We use cookies and similar technologies that are necessary to keep you signed in and to remember preferences (such as light/dark mode). Analytics, if enabled, may use privacy- friendly measurement. You can control cookies through your browser settings.

5. Data retention

We keep your information for as long as your account is active or as needed to provide the Service. You can delete a connected league at any time, and you can request deletion of your account and associated data by contacting us. We may retain limited records where required by law (e.g. billing records).

6. Your rights

Depending on where you live, you may have rights to access, correct, export, or delete your personal information, or to object to certain processing. To exercise these rights, contact us at the address below. We will respond as required by applicable law.

7. Security

We use reasonable technical and organizational measures to protect your information. No method of transmission or storage is completely secure, however, and we cannot guarantee absolute security.

8. Children

The Service is not directed to children under 13 (or the minimum age in your jurisdiction), and we do not knowingly collect their personal information. If you believe a child has provided us information, contact us and we will delete it.

9. Changes to this Policy

We may update this Policy from time to time. We will update the “Last updated” date and, for material changes, provide additional notice where appropriate.
