Privacy policy

Last updated November 10, 2026

What we collect

• Your email address, to send sign-in codes and link you to the leagues you import.
• League data from the platform you import from: league and team names, manager display names, standings and scores. League pages are public to anyone with the link.
• Newsletter emails, added by a league's commissioner or by members who sign up, used only to send that league's weekly newsletter. Every email has an unsubscribe link, and someone who unsubscribes can't be re-added by the commissioner.
• ESPN sign-in cookies (espn_s2 and SWID), only for private ESPN leagues and only when you provide them, either by hand or with the Fantasy Deep Dive Chrome extension.

Google and Yahoo sign-in

If you use "Continue with Google", we receive only your email address from Google, to sign you in. If you connect Yahoo, we receive read-only access to your Yahoo Fantasy leagues and keep an encrypted access key so the league you imported can be re-synced. We never see your Google or Yahoo password, and deleting the league removes the key.

How ESPN cookies are used

They are stored encrypted and used only to read the scores and standings of the league you connected. They are never shared, sold, or used for anything else. The Chrome extension reads no other cookies or browsing data and sends nothing anywhere except fantasydeepdive.com.

Cookies

We use one cookie to keep you signed in. If you don't sign in, we don't set it.

Advertising

We show ads from Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.

You can opt out of personalized advertising in Google's Ads Settings, or opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info. See how Google uses information from sites that use its services.

Visitors in the European Economic Area, the UK and Switzerland are asked for consent before personalized ads are shown.

What we don't do

We don't sell personal data, and we never give your email address or league data to advertisers. Ads are never placed in newsletter emails.

Deleting your data

Delete a league from its Manage page and its data and saved ESPN cookies are removed. To delete your account entirely, email hello@fantasydeepdive.com.
