Privacy Policy

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 betting 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
• Bookmaker, 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
• Promotional content: New features, offers, or platform updates
• Urgent notifications: Time-sensitive information (e.g., event starting soon)

How notifications work:

• Delivery: The extension checks for new notifications every 60 seconds (polling)
• Privacy: Notification checks only occur when you have active browser tabs open
• Display: Notifications appear as overlay messages on sportsbook pages
• Control: You can manage notification preferences in the extension settings

Notification Retention:

• Guest Users (Not Signed In): Notification history is retained for 7 days
• Authenticated Users (Signed In): Unlimited notification history

Your Rights:

• You can dismiss any notification
• You can disable specific notification types in extension settings
• You can request deletion of your notification history

2.5 Remote Extension Management

To ensure system stability, prevent abuse, and protect our users, OddsGuard implements the following remote management features:

Version Enforcement

We may require users to update to a minimum extension version for security or compatibility reasons. When a new minimum version is set:

• Grace Period: Users receive 7 days' notice before older versions are blocked
• Notification: A once-per-day notification reminds users to update
• Purpose: Ensure all users have critical security patches and bug fixes

Rate Limiting

We monitor API usage to prevent abuse and ensure fair access for all users:

• Tier 1 (Odds Comparison): Strict limits on odds API calls
• Tier 2 (Notifications): Lenient limits on notification polling
• Automatic Actions: Extensions exceeding limits may be temporarily disabled
• Appeal: Contact support if you believe your extension was disabled incorrectly

IP-Based Blocking

We may block IP addresses exhibiting abusive patterns (e.g., automated scraping, DoS attacks):

• CIDR Range Support: Entire IP ranges may be blocked if necessary
• Temporary & Permanent Blocks: Blocks may expire or be permanent depending on severity

Remote Disable

We reserve the right to remotely disable extensions engaged in:

• Automated abuse (bots, scrapers)
