Privacy Policy

What we collect

• If you use a comparison without signing up: nothing personally identifying. We log your IP address briefly, only to enforce a fair-use rate limit, and don't retain it beyond that.
• If you create a free account: your name, email address, favourite team, and whether you opted in to product updates.
• If you connect a Sleeper league: your Sleeper username and the league/roster data Sleeper's public API returns for that league, so we can personalise advice to your team. We only read this data — we never post to your Sleeper account.

Who we share it with

• Anthropic — the statistical data behind a comparison (not your account details) is sent to Anthropic's API to generate the written analysis.
• Supabase — hosts our database and handles sign-in.
• Resend — delivers the magic-link sign-in emails.
• Vercel — hosts the site and provides basic, privacy-friendly traffic analytics (no cross-site tracking or ad cookies).

We do not sell your data, and we do not run ad trackers.

Cookies

We use a single cookie to keep you signed in. That's it — no advertising or cross-site tracking cookies.

Your choices

You can disconnect your Sleeper league or delete your account at any time from Account. To fully delete your data, email us and we'll remove it.
