These Terms of Service ("Terms") govern your use of the Test4X apps and websites (the "Service"), operated by Guanghua Hu, a sole proprietorship registered in Québec, Canada (NEQ: 2282141524). By using the Service you agree to these Terms.
Test4X is an independent study aid. It provides exam-style practice questions, answers, and explanations intended to help you prepare. It is not a course, and it does not issue any licence, certificate, or credential.
Using the Service does not guarantee that you will pass any exam or obtain any licence. You are responsible for meeting the actual requirements set by the relevant authority.
Test4X is not affiliated with, endorsed by, or sponsored by any government agency, licensing authority, testing provider, or the owners of any exam named on the Service. Our practice questions are not copies of any official exam. All trademarks and official exam materials are the property of their respective owners.
Practice questions and explanations are generated with the help of AI and provided for study purposes only, without individual human expert review. They may contain errors or become out of date, and do not constitute legal or professional advice. Always confirm rules and requirements with the official materials issued by the relevant authority.
Creating an account is optional; you may use the Service as a guest. If you create an account, you are responsible for the accuracy of the email address you provide and for activity under your account. See our Privacy Policy for how we handle your data.
Some features require a paid plan. Prices are shown before purchase. Payments are processed by Apple In-App Purchase (iOS), Google Play (Android), or Stripe/PayPal (web) — we never see or store your card details.
Subscriptions and one-time purchases are non-refundable except where required by applicable law or by the platform's own store policy. For purchases made through Apple or Google, refunds are handled under those stores' policies. For web purchases, contact us at support@test-4-x.com.
You agree not to copy, resell, scrape, or redistribute the Service's content, or to use the Service in any unlawful way. The Service and its content are protected by intellectual-property rights.
To the maximum extent permitted by law, the Service is provided "as is" without warranties of any kind. We are not liable for any indirect or consequential damages, or for outcomes of any exam, arising from your use of the Service. Nothing in these Terms limits rights that cannot be limited under applicable consumer-protection law.
We may update these Terms from time to time; the "Last updated" date reflects the latest version. These Terms are governed by the laws of the Province of Québec and the laws of Canada applicable there.
