Privacy Policy

1. Introduction

Welcome to Compatibility Hub ("we", "us", "our"). We are committed to protecting your privacy and ensuring the security of your personal information. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website and services.

2. Information We Collect

We may collect the following types of information from users:

• Personal Information: We do not directly collect personal information through forms or user accounts. However, third-party services such as Google AdSense and Google Analytics may automatically collect technical data (including IP addresses and cookies) as described in Section 4. If you contact us via email, we may retain your email address to respond to your inquiry.
• Usage Data: Information about how you interact with our website, including test results and preferences.
• Technical Data: IP address, browser type, operating system, and device information.

3. How We Use Your Information

We use the information we collect to:

• Provide and maintain our services
• Improve and personalize your experience
• Analyze usage patterns to improve our services
• Ensure the security of our platform
• Serve and measure advertisements
• Analyze website traffic and usage statistics

4. Third-Party Services

We may use third-party services that collect information:

• Google AdSense: We use Google AdSense to display advertisements. Google and its partners may use cookies, web beacons, and device identifiers (including IP address) to serve and measure ads. This data may also be used to personalize ad content based on your prior interactions. You can manage personalized advertising via Google Ads Settings. See Google's Advertising Privacy Policy for details.
• Google Analytics: We use Google Analytics to understand how visitors interact with our website. It collects data such as page views, session duration, and traffic source using cookies. See Google's Privacy Policy for details.
• Cloudflare Turnstile: Security verification to prevent automated abuse.
• DeepSeek API: AI-powered analysis for our compatibility tests.
• Analytics: To understand how users interact with our website.

5. Local Storage and Test History

Our website uses your browser's local storage to save your compatibility test results for your convenience. This feature allows you to review past results without having to retake tests.

• What is stored: Test results, including scores, input selections, and AI-generated analysis text, are stored locally on your device.
• Where it is stored: Test results are stored locally in your browser. When you request AI analysis, your test scores and descriptions are sent to our server and forwarded to our AI provider (DeepSeek) for processing. This data is not stored on our servers after the analysis is completed. Your raw answers are never uploaded — only the computed scores.
• Data compression: We use LZString compression to minimize the storage space used on your device.
• Record limits: A maximum of 100 test records are stored. When this limit is reached, the oldest records are automatically removed.
• Your control: You can delete individual records or clear all history at any time from the History page. You can also clear all locally stored data by clearing your browser's site data.
• Private browsing: Local history is not available in private browsing mode as browser storage is typically disabled.

6. Data Storage and Security

We take reasonable measures to protect your information from unauthorized access, disclosure, or destruction. However, no method of transmission over the internet or electronic storage is 100% secure.

7. Your Rights

You have the right to access, correct, or delete your personal information. If you wish to exercise these rights, please contact us at [email protected].

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page.
