Privacy & data

If you never sign in

Your work stays in your own browser, in local storage on the device you made it on. It is not sent anywhere, and clearing your browser data deletes it permanently — there is no copy to restore from.

• Cheat sheets you build on the draft page, including every ranking edit.
• Rankings you paste or import from CSV.
• The Sleeper username you last looked up, so the leagues page remembers it.
• Display preferences — light or dark theme, and which sources you had selected.

If you sign in

Signing in with Google creates an account held by Supabase, this app’s database provider. From that point the following is stored on their servers:

Your Google account

Email address, display name, and profile picture URL, received from Google when you sign in and held by Supabase Auth. No password is ever created or stored, and nothing is requested from your Google account beyond your basic profile — no Gmail, no Drive, no contacts.

Your cheat sheets

A copy of the sheets already in your browser, so they survive a lost device. Name, settings, and your per-player edits.

Rankings you imported

The boards you pasted or uploaded, stored whole so they follow you between devices.

Your Sleeper connection

Username, Sleeper user id, display name and avatar — identifiers only. Your leagues, rosters, and draft picks are fetched live from Sleeper each time and are never copied into this app's database.

Every one of those rows is protected by row-level security, meaning the database itself refuses to return another account’s data — not merely that this app declines to ask for it.

Cookies

One kind, and only while you are signed in: the session cookie Supabase uses to keep you signed in between page loads. There are no analytics cookies, no advertising cookies, and no third-party trackers, so there is no consent banner to dismiss. Signing out removes it.

Where your data is held

Accounts and backups sit with Supabase, and the site itself is hosted by Vercel. Both act as processors for this app and both may hold data outside the EEA under their own standard contractual clauses. Sign-in is handled by Google.

Your rights, and how to use them

You can ask for a copy of everything stored about you, ask for it corrected, or ask for it deleted — and deletion here is genuinely complete: removing the account removes the cheat sheets, the imported rankings and the Sleeper connection with it, because every table is keyed to the account and cascades. Email hello@fantasyfootballtool.com and say which you want. There is no automated deletion button yet; a request is answered by hand.

If you would rather not wait, signing out and clearing your browser data removes the local copy immediately, and the server copy is inert without it.

Where the rankings come from

This app publishes no rankings of its own. Every board shown here is the work of the publisher named beside it, reproduced with attribution and linked back to the source. Rankings and projections remain the property of their publishers, and the presence of a source on this page is a citation, not a partnership or an endorsement by them.

FantasyPros

Consensus rankings, individual expert boards, and projections.

CBS Sports

Expert and consensus rankings.

ESPN Fantasy

Staff rankings and average draft position.

Yahoo Fantasy

Average draft position.

FantasyCalc

Market trade values, from real completed trades.

Sleeper

Your league, roster and draft data, and the player identity map.

If you publish one of these boards and would rather it were not shown here, email the address above and it will be removed.

Changes

If what is stored ever changes, this page changes with it and the date at the top moves. There is no mailing list to notify, because there is no mailing list.
