Privacy Policy

Last Updated: December 24, 2025
1. Introduction

At OddsGuard, we take your privacy seriously. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website, browser extension, and related services.

OddsGuard is a sports odds comparison platform that provides information about betting odds from various operators. We do not offer gambling services, accept bets, or process payments for betting activities.

Please read this Privacy Policy carefully. By accessing or using OddsGuard, you acknowledge that you have read, understood, and agree to be bound by all the terms of this Privacy Policy.
2. Information We Collect
2.1 Personal Information

We may collect personal information that you voluntarily provide to us when you:

Register for an account
Sign up for our newsletter
Contact us through our website
Participate in surveys or promotions


This information may include your name, email address, and other contact details.
2.2 Usage Information

We automatically collect certain information about your device and how you interact with OddsGuard, including:

IP address and geolocation data (country and region level only)
Browser type and version
Operating system
Pages visited and time spent on those pages
Referring website addresses
Sports and markets you view


2.3 Browser Extension Data

If you use our browser extension, we collect the following data to provide, improve, and secure our services:
2.3.1 Anonymous Installation Tracking

When you install the OddsGuard browser extension, we assign a unique identifier called an "Installation UUID" to your browser. This identifier is used for anonymous usage tracking and system stability monitoring.

Important clarifications:

Installation UUID is a custom identifier we generate (e.g., 550e8400-e29b-41d4-a716-446655440000)
NOT Chrome's Extension ID - The Installation UUID is different from Chrome's built-in Extension ID
Purpose: Track extension installations, monitor system health, detect abuse, and measure performance
Anonymous: The Installation UUID does not contain any personally identifiable information
Deletion: You can request deletion of your Installation UUID data at any time
Storage: Stored locally in your browser and on our servers for analytics


Why we need this:

System Health: Monitor extension stability and error rates
Abuse Detection: Identify and block malicious usage patterns (e.g., rate limit violations)
Feature Usage: Understand which features are most valuable to users
Regional Analytics: Show relevant odds for your location


2.3.2 Extension Usage Tracking

We track the following activities when you use the OddsGuard extension:

Sport Detection & Resolution:

URLs of supported pages you visit (e.g., draftkings.com/sportsbook/nfl)
Sports, events, and markets you view
Sport detection confidence scores
API calls to our odds comparison service


Affiliate Link Tracking:

When you click affiliate links from our extension
Provider, sport, event, and market associated with each click
Timestamp and referring URL
Geographic location (country and state/province only)


Notification Engagement:

When notifications are delivered to your extension
When you read, dismiss, or click notification action buttons
Notification types (system, odds, marketing, urgent)


Important limitations:

✅ We ONLY track activity on supported websites
❌ We DO NOT track your general web browsing
❌ We DO NOT access passwords, payment information, or personal messages
❌ We DO NOT track activity on non-supported websites


Purpose:

Improve odds comparison accuracy
Measure affiliate link performance (helps us keep the service free)
Optimize notification relevance and timing
Detect and prevent abuse


2.3.3 Uninstall Tracking & Exit Survey

When you uninstall the OddsGuard extension, we track the uninstall event and invite you to complete an optional exit survey.

What we collect:

Uninstall Date & Time: When you uninstalled the extension
Installation Duration: How many days you used the extension
Exit Survey (Optional):
Star rating (1-5 stars)
Uninstall reason (9 predefined options)
Optional comment
Optional email address for follow-up


Important:

Soft Delete: We mark your installation as "disabled" but retain the record for analytics
Anonymous: Uninstall data is analyzed in aggregate, not individually
Optional Survey: You can skip the exit survey - it is completely voluntary
Deletion Rights: You can request full deletion of your uninstall data at any time


Purpose:

Understand why users uninstall the extension
Identify product issues and improvement opportunities
Measure retention and user satisfaction
Respond to user concerns (if you provide an email address)


How it works:

When you uninstall, Chrome automatically opens our exit survey page
Your Installation UUID is passed to the survey page via URL parameter
If you submit the survey, your feedback is associated with your installation record
If you close the page without submitting, we only record the uninstall event (no feedback)


2.4 Extension Notifications

The OddsGuard extension may deliver notifications to keep you informed about:

System updates: Critical extension updates, maintenance, or security alerts
Odds alerts: New odds, value bets, or arbitrage opportunities
Marketing content (Optional - Requires Opt-In): Special offer offers, special promotions, new features, and exclusive deals

Easy Opt-Out: You can withdraw consent at any time by contacting privacy@oddsguard.org
No Impact on Service: Declining marketing notifications does NOT affect core extension functionality


How notifications work:

2.5 Remote Extension Management

Automated abuse (bots, scrapers)
