Privacy Policy

Effective Date: April 15, 2026  |  Last Updated: October 11, 2026

This Privacy Policy describes how EPA 608 Practice Test ("we," "us," or "our") collects, uses, and shares information when you use our website at epa608practicetest.net (the "Service"). Please read this policy carefully.

1. Who We Are

EPA 608 Practice Test is an independent educational platform for HVAC technicians and students preparing for the EPA Section 608 certification exam. We are not affiliated with the Environmental Protection Agency, ESCO Institute, Mainstream Engineering, or any government body.

Contact: privacy@epa608practicetest.net

2. Information We Collect

2.1 Information Stored Locally in Your Browser (Free Users)

The Free tier requires no account and no login. Test results, progress history, quiz scores, and preferences are saved only in your browser's localStorage. This data never leaves your device and is not transmitted to our servers. Clearing your browser's storage permanently deletes all of it.

2.2 Information You Provide Voluntarily

• Contact form: If you contact us via our contact form, we collect your name and email address. This is used only to respond to your inquiry.
• Notify / waitlist form: If you submit your email on the pricing page to receive launch notifications, we store that email to send you the notification you requested.
• AI Tutor conversations: When you use the AI Tutor or an "Explain" button, we store the question you sent, the answer the AI gave, and any thumbs up or thumbs down rating and comment you add. We use these to check that answers are accurate, fix wrong or confusing ones, and see where students get stuck.
• Problem reports: If you use "Report a problem", we store your message, the page you were on, and your account (if signed in) so we can investigate and reply.
• Pro Lifetime purchase: When you purchase Pro access, Polar Software, Inc. collects your email, name, and payment information. We receive your email address from Polar Software, Inc. to verify and activate your Pro access. We do not receive your card number, billing address, or other payment details.

2.3 Usage Data (Automatically Collected)

When you use the Service, we automatically collect certain technical information through Google Analytics and Vercel Analytics, including:

• Pages visited and time spent on each page
• Browser type, operating system, and device type
• Country level location (not precise geolocation)
• Referring website or search query
• Events such as completing a practice test or clicking a button

This data is aggregated and used to understand how the Service is used and improve it. It is not used to identify individual users.

3. Payment Data and Polar Software, Inc.

All payments for Pro Lifetime access are processed by Polar Market Limited ("Polar"), who acts as the Merchant of Record for all transactions.

Polar Software, Inc. is independently PCI DSS compliant and handles all payment security. Polar's Privacy Policy governs the handling of your payment information: polar.sh/legal/privacy
