FF Draft Tool

Privacy Policy

Last updated September 2026

FF Draft Tool (the website and its companion Chrome extension) is a personal fantasy football rankings and draft-assistant tool. This page explains what data it collects, why, and what it does with it.

What we collect

  • Account info — your email address and password, used only to log you in. Passwords are handled directly by our authentication provider, Supabase; we never see or store them in plain text.
  • Your rankings — the player order you create on the site, so it can be shown back to you (on the site and in the extension) and edited across sessions.
  • AI insight requests (only if you enable that feature) — a player's name, position, and team are sent to Anthropic's Claude API to generate a short scouting note. No account or personal information is included in that request.

The Chrome extension specifically

  • Stores your login session (an access token) locally in your browser via chrome.storage, so it can fetch your rankings on your behalf. This never leaves your browser except to authenticate directly with our database provider, Supabase.
  • Reads the draft-room page you're viewing on ESPN or Sleeper (only to detect which players have already been drafted) entirely inside your browser. That page content is never transmitted anywhere or stored.
  • Your chosen display settings (format, how many players to show) are stored locally via chrome.storage and are not sent to us.

Who we share it with

We don't sell your data or share it with advertisers. Data is processed by the infrastructure providers that run this service: Supabase (database and authentication), Vercel (hosting), and, only if you enable AI insights, Anthropic.

Cookies

The website uses a single session cookie to keep you logged in. We don't use tracking or advertising cookies.

Data retention & deletion

Your account and rankings are kept for as long as your account exists. To request deletion of your account and data, open an issue on the project's GitHub repository from the email address on your account.

Children's privacy

This tool isn't directed at children and isn't knowingly used to collect data from anyone under 13.

Changes to this policy

If this policy changes, the “last updated” date above will change too. Continued use of the tool after an update means you accept the revised policy.
