1. Use of the platform
ACA provides online Chinese learning content, courseware, study cards, learning tools, live-class access, teacher assets, and community features. You agree to use the platform for lawful learning and teaching purposes.
You are responsible for keeping your login access secure and for activity under your account.
2. Membership and access
Some courses, study cards, live rooms, downloads, and teacher resources may require a paid membership, manual grant, or other entitlement. Access may expire, be limited by plan, or be revoked for misuse.
ACA may update course availability, learning tools, pricing, and membership benefits as the platform develops.
Annual memberships include a 7-day satisfaction refund window, but downloadable digital products are handled separately under the Refund Policy. Study cards, PDFs, audio packs, teacher courseware, classroom slides, handouts, printable materials, and similar files may be treated as delivered once downloaded.
3. Intellectual property
ACA courseware, study cards, text, images, audio, lesson structures, downloads, and platform materials are owned by ACA or its licensors unless otherwise stated.
You may use the materials for personal learning or authorized teaching use. You may not resell, mass redistribute, scrape, copy into another product, or remove attribution without permission.
4. Community conduct
You must not post spam, harassment, illegal content, adult content, hate, threats, private information, advertising, political provocation, scams, or content unrelated to learning Chinese.
ACA may hide, delete, review, restrict, mute, or ban accounts that violate these terms or the Community Guidelines.
5. No guaranteed results
ACA aims to support structured Chinese learning, but language progress depends on personal effort, time, practice quality, and learning background. ACA does not guarantee a specific exam score or result.
