Privacy Policy | Waiver Wizard

Introduction

Fantasy Sports Analytics LLC ("we," "our," or "us") operates Waiver Wizard (fantasywaiverwizard.com). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our service.

Information We Collect

Account Information: When you create an account, we collect your email address and password (securely hashed).

League Credentials: To provide our service, we collect your league ID and platform-specific credentials (ESPN: SWID and espn_s2 cookies; Sleeper: username only). These are used solely to access your league's waiver wire data.

Payment Information: If you subscribe to a paid plan, payment processing is handled by Stripe. We do not store your credit card information directly.

Phone Number: Premium subscribers may optionally provide a US mobile phone number to receive SMS alerts. Providing your phone number is entirely voluntary and requires explicit opt-in via a verification code. Your phone number is used solely to deliver Waiver Wizard SMS alerts (roster injury and waiver status changes) and is never used for marketing, sold, or shared with third parties. You can remove your number at any time from Settings or by replying STOP to any message.

Usage Data: We may collect information about how you use our service, including alert preferences and settings. We use Vercel Analytics to collect anonymous, aggregated page view data to understand how visitors use our site. No personally identifiable information is collected by Vercel Analytics.

Chrome Extension — ESPN Connector

The Waiver Wizard ESPN Connector is an optional Chrome extension that replaces the manual step of copying your ESPN session cookies out of Developer Tools when connecting a private ESPN league. You never have to install it — manual entry is always available as a fallback during onboarding.

What it accesses: if installed, the extension can read the SWID and espn_s2 session cookies for espn.com using Chrome's cookies API. It never sees or asks for your ESPN password.

When it acts: opening the extension's toolbar popup reads the cookies locally, in your browser only, to show you whether you're currently logged in to ESPN — nothing is sent anywhere at that point. The cookies are only ever transmitted off your device when you click "Connect with the ESPN Connector" on the private-league credentials step of onboarding. The extension does not monitor your browsing or act on its own; it only responds when you open its popup or a page on fantasywaiverwizard.com asks it to.

Where the data goes: the cookies are sent only to fantasywaiverwizard.com, and only at the moment described above — the extension is configured to respond exclusively to requests from our domain, so no other website can use it to request your ESPN session.

Uninstalling the extension does not affect any league you've already connected — it only removes the one-click convenience path for future connections.
