Terms of Service

1The service

FE Exam AI Prep is operated by Hangzhou Star Vision Technology Co., Ltd. (“we,” “us,” or “our”). It is an exam-preparation study tool delivered through this website and its web member center (together, “the service”). Your account carries your available plan, progress, streak, and subscription records across supported web browsers. By creating an account or using the service you agree to these terms.

Each paid subscription covers one FE discipline selected before checkout and the features listed as available for that discipline on the pricing page when you buy. Changing the discipline shown in the member center does not transfer the subscription to another discipline. FE Exam AI Prep mobile apps are covered by these terms where applicable; the Android app is currently available through Google Play. Web and app-store purchases are billed and managed through their original checkout channel, with applicable product details and terms presented before purchase.

2Your license & fair use

We grant you a personal, non-transferable, revocable license to use the service for your own exam preparation. A subscription is tied to the account used to buy it and is for one person.

• Don't resell access, share an account commercially, or use one account for a class or company — we may limit devices or restrict access if an account is used for improper profit.
• Don't scrape, bulk-export, or republish the question bank, solutions, formula reference, or course videos.
• Don't access the service with automated tools except the interfaces we provide.

3Accounts

On the web you create or access an account with an email link or password. You're responsible for keeping your sign-in method secure; tell us at contact@xingshiyu.com.cn if you think someone else is using your account.

4Subscriptions & billing

• Where you buy. Paddle.com acts as our online reseller and Merchant of Record for web orders. Paddle processes the payment and handles payment-related customer service and returns; we provide product and account support. We never receive or store your full card details.
• Auto-renewal. Monthly and annual plans are auto-renewable subscriptions. The checkout identifies the amount, currency, billing period, taxes, and any trial before you confirm. The plan renews for the same billing period until you cancel, subject to any notice and consent required by law for a price change.
• Cancel. For a web purchase, use the Paddle-hosted billing portal available from account settings or from your purchase email. Cancellation normally takes effect at the end of the current paid period, so you keep access until then and are not charged for a later renewal.
• Refunds. Eligibility depends on the purchase channel, mandatory consumer rights, and the applicable policy. Web purchases are governed by our Refund & Cancellation Policy and Paddle's buyer terms.
• What plans include. Paid plans differ in price, billing period, and monthly AI-credit allowance, and each purchase covers one selected FE discipline. Max additionally unlocks the published half mocks for that discipline; FE Civil Max includes the FE Civil course videos and study notes published in the web member center. The pricing page and checkout describe the current benefits before you buy; planned or unreleased native-app features are not included in the current web subscription.

Web purchases through Paddle are also subject to Paddle's Buyer Terms.

5AI credits & AI features

AI credits are a consumable used only for optional live-AI features (the AI coach, on-demand explanations, and practice-session analysis). They never expire, have no monetary value, and cannot be transferred or exchanged for cash. The core study experience does not require them.

AI-generated answers can be wrong. The coach is a study aid, not an authority on the exam — check anything that matters against the public exam specification and your own judgment.

6Our content & how questions are made

All paid educational content sold through the service — including practice questions, answer choices, worked solutions, lesson scripts, study notes, and videos — is independently created for and owned by Hangzhou Star Vision Technology Co., Ltd. Publicly available FE topic outlines are used only to plan subject coverage.

We do not copy, adapt, paraphrase, reproduce, or resell real or recalled exam questions, NCEES practice materials or Reference Handbook pages, tables, numbering, or explanations, or third-party question banks and courses. Questions and solutions pass through internal technical, mathematical, and editorial checks before publication.

If you see anything wrong, use “Report an issue” on any question — repeated independent reports automatically suspend a question from the practice pool while it's rechecked.

Third-party software and service providers supply technical infrastructure only; they are not the source of the educational content we sell. The service's software is ours or is used under valid software licenses. Notes you write in the product are yours.

7Marketing language we will not use

You will never see “real exam questions”, “past exam questions”, a pass guarantee, or any claim of endorsement by a testing organization in this product. We say “original practice questions”, “exam-style practice”, and “readiness tracking” — because that's what this is.

8Independence & no guarantee

The service is provided for study purposes “as is”, without warranty of any kind. Readiness estimates are study signals, never predictions — we do not guarantee any exam result.

Readiness indicators summarize your own practice activity only to help you plan study. They do not determine exam eligibility, admission, employment, professional licensure, or any other consequential decision, and we do not provide them to NCEES, licensing boards, schools, or employers for those purposes.

9Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, or consequential damages arising from your use of the service, and our total liability for any claim is limited to the amount you paid for the service in the twelve months before the claim. Nothing in these terms limits liability that cannot be limited by law.

10Ending or changing things

• You can stop using the service anytime and can request account deletion from Settings. Deleting an account does not itself cancel a subscription; cancel separately in the Paddle billing portal.
• We may suspend or terminate accounts that violate these terms, after notice where practical.
• If we make material changes to these terms, we'll update the effective date above and tell you on the website or by email before they take effect.
