Terms of Service

CSCA.app is an online exam preparation platform for the China Scholastic Competency Assessment (CSCA) examination. We provide practice questions, mock exams, glossaries, blog articles, university information, and related study resources across subjects including Math, Physics, and Chemistry. Some parts of the Service are offered free of charge. Other parts — in particular online mock exams and downloadable past-paper bundles — are paid digital products.

The Service is intended for students preparing for university entrance examinations, typically aged 16 or older. If you are under the age of majority in your jurisdiction, you represent that you have obtained your parent's or legal guardian's consent to use the Service. To access certain features (including saving exam results, purchase history, and favorites), you must create an account via our authentication provider (Clerk). You are responsible for: - Providing accurate and up-to-date information; - Maintaining the confidentiality of your account credentials; - All activity that occurs under your account. You may delete your account at any time from within the app, or by emailing success@csca.app. Account deletion is described further in our Privacy Policy.

All content made available through the Service — including but not limited to exam questions, mock exams, answer explanations, glossaries, blog articles, images, icons, trademarks, logos, and the underlying software — is owned by CSCA.app or its licensors and is protected by Chinese and international copyright, trademark, and other intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your personal, non-commercial study use only. You may not: - Copy, reproduce, republish, distribute, sell, rent, sublicense, or otherwise exploit any part of the Service; - Scrape, crawl, or use automated means to extract data from the Service; - Remove any copyright, trademark, or proprietary notices; - Use the Service to train machine-learning models without our express written consent.

CSCA.app sells paid digital products, including access to online mock exams and downloadable past-paper bundles. Pricing is shown in the Service and may change from time to time. **4.1 Payment channels by platform.** The available payment methods depend on the platform you use: - **iOS app (Apple App Store):** All purchases of paid digital content within our iOS app must be made through Apple's In-App Purchase (IAP) system. Payment is processed by Apple in accordance with the Apple Media Services Terms and Conditions. We do not accept any other payment method inside the iOS app. - **Android app (Google Play):** All purchases of paid digital content within our Android app must be made through Google Play Billing. Payment is processed by Google in accordance with the Google Play Terms of Service. - **Website (csca.app):** On the web, purchases are processed by our third-party payment partners. International card payments and digital wallets are processed by Gumroad (Gumroad, Inc., USA) and Xendit (PT. Xendit Teknologi / Xendit, Inc.), which supports credit and debit cards, local bank transfers, and regional e-wallets in Southeast Asia (including Indonesia, the Philippines, Vietnam, Thailand, and Malaysia). For users in mainland China, we additionally accept WeChat Pay and Alipay by contacting us via email; in that case we will send a payment request and deliver the product manually within 1–2 business hours. By submitting payment information, you represent that you are authorized to use the payment method and you authorize the applicable payment processor to charge the total amount shown at checkout, including any applicable taxes and currency-conversion fees. Card payments are further subject to the rules of the applicable card networks (Visa, Mastercard, JCB, American Express, etc.). **4.2 Delivery of digital products.** All products sold through CSCA.app are digital, intangible, and delivered electronically. Upon successful payment confirmation from the applicable payment processor, access is granted and/or download links are provisioned automatically within a few seconds, and in any event within 24 hours. Delivery occurs entirely within the Service or by email to the address associated with your account. No physical goods are shipped. **4.3 Access period.** Unless stated otherwise on the product page, paid mock-exam access is granted for a fixed access period displayed at the time of purchase. Past-paper downloads are delivered as files which you may keep after the access period ends. **4.4 No refunds for digital goods.** Paid digital products are delivered and consumed instantly. To the fullest extent permitted by applicable law, **all sales of digital products are final and non-refundable** once access has been unlocked or the download link has been delivered. This includes (without limitation) online mock-exam access and past-paper download bundles. By completing a purchase, you expressly acknowledge that (a) the product is delivered digitally and immediately, (b) you waive any statutory "cooling-off" or cancellation right to the extent such waiver is permitted by the laws of your jurisdiction, and (c) no refund will be issued after delivery has been completed. For purchases made via Apple IAP or Google Play Billing, refund requests are handled by Apple or Google respectively under their own refund policies; we are not able to process those refunds directly. For Gumroad, Xendit, and WeChat Pay / Alipay purchases, please contact success@csca.app within seven (7) days of the charge if you believe a charge is incorrect — we will review genuine billing errors, duplicate charges, or unauthorized transactions on a case-by-case basis. **4.5 Chargebacks and card disputes.** Because our products are digital and are delivered immediately, we ask that you contact us at success@csca.app to resolve any billing concern before initiating a chargeback or card dispute with your bank or card issuer. We maintain transaction logs (including purchase timestamps, IP address, device information, and delivery confirmation) and will provide such evidence to payment processors, card networks, and banks to contest any chargeback we believe to be unjustified. Repeated or fraudulent chargebacks may result in the suspension or termination of your account and forfeiture of any remaining access.

When using the Service, you agree not to: - Violate any applicable law or regulation; - Share, resell, or otherwise distribute paid content (including exam questions and answer keys) to third parties; - Upload or transmit any material that is unlawful, infringing, defamatory, obscene, or otherwise objectionable; - Interfere with or disrupt the Service, its servers, or the networks connected to it; - Attempt to gain unauthorized access to any part of the Service, other user accounts, or related systems; - Use the Service to cheat on any official examination or in any way that violates the rules of an educational institution; - Impersonate any person or misrepresent your affiliation with any person or entity. We reserve the right to suspend or terminate your access to the Service if we reasonably believe you have violated these Terms.

The Service relies on a number of third-party providers, including but not limited to: Clerk (authentication), Supabase (database), Vercel (hosting), Google Analytics (web analytics), Resend (email delivery), Gumroad and Xendit (web payments), and Apple / Google (mobile payments). Your use of those providers' services may also be subject to their own terms and privacy policies. The Service may contain links to third-party websites. We are not responsible for the content or practices of any linked third-party sites.

CSCA.app is an independent study platform. We are not affiliated with, endorsed by, or sponsored by the Chinese Ministry of Education or any official CSCA examination authority. References to the CSCA examination, universities, and scholarships are provided for informational purposes only. The Service is provided "as is" and "as available", without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not guarantee that the Service will be uninterrupted, error-free, or free of harmful components, nor that the practice content will match the content of any actual examination.

To the fullest extent permitted by applicable law, in no event shall CSCA.app, its affiliates, officers, employees, or agents be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or goodwill, arising out of or in connection with your use of the Service — even if we have been advised of the possibility of such damages. Our total aggregate liability to you for any claim arising out of or related to the Service shall not exceed the amount you paid to us in the twelve (12) months preceding the event giving rise to the claim, or USD 50, whichever is greater.

We may modify, suspend, or discontinue any part of the Service at any time, with or without notice. We may also terminate or suspend your access to the Service at any time if you breach these Terms. Upon termination, your right to use the Service will cease immediately. Sections of these Terms that by their nature should survive termination (including intellectual property, disclaimers, limitation of liability, and governing law) shall survive.

These Terms and any dispute arising out of or related to them or the Service shall be governed by and construed in accordance with the laws of the People's Republic of China (mainland), without regard to its conflict-of-laws principles. You agree that any dispute shall first be addressed through good-faith negotiation by contacting us at success@csca.app. If the dispute cannot be resolved informally, it shall be submitted to the competent people's court at our principal place of business in mainland China. Nothing in this section limits any mandatory consumer-protection rights you may have under the laws of your country of residence.

We may update these Terms from time to time to reflect changes to the Service, to our business, or to applicable law. When we make material changes, we will update the "Last Updated" date at the top of this page and, where appropriate, notify you through the Service or by email. Your continued use of the Service after the updated Terms take effect constitutes your acceptance of the changes.
