This Cookie & Tracking Policy explains how CleanSlate DFS, LLC ("Company," "we," "us," or "our") uses cookies, local device storage, and similar technologies on our website at cleanslatedfs.com and within the CleanSlate DFS mobile application.

1. What Are Cookies and Local Storage?

Cookies are small text files placed on your device by a web browser to remember session state and basic preferences. Modern mobile applications and single-page applications use encrypted Local Storage / Keychains to retain authentication tokens and user configuration settings across app launches without writing browser cookies.

2. How We Use Tracking Technologies

CleanSlate DFS operates on a software subscription model. We do not sell user data, deploy third-party cross-site advertising networks (such as Meta Pixel or Google AdSense), or use offer walls.

Our technologies fall exclusively into the following functional categories:

• Strictly Necessary & Authentication: Secure authentication tokens (JSON Web Tokens via Supabase) are stored locally on your device to keep you securely signed in across sessions.
• System Security & Infrastructure: Cloudflare edge routing and DDoS prevention cookies protect our API servers and website against automated attacks.
• Subscription Entitlements: Synchronizing your active subscription tier (Casual vs. Pro) verified via App Store or Google Play in-app purchase receipts.
• UI Preferences: Locally caching your default sport, preferred contest operator formats (DraftKings vs. FanDuel), and interface presets.

3. Third-Party Service Providers

We work with trusted infrastructure providers who may utilize necessary security tokens and session cookies solely to deliver application services:

Provider	Purpose	Type
Cloudflare	DDoS protection, DNS routing, and edge SSL security	Strictly Necessary
Supabase	Encrypted user authentication and session token validation	Strictly Necessary
Apple App Store	iOS mobile in-app purchase processing and entitlement checks	Billing & Security

4. Managing Your Preferences

Web Browsers: You can configure your browser to block or alert you about cookies via your browser settings (Chrome, Safari, Firefox, Edge). Note that blocking essential session cookies may prevent account login functionality.
