Terms of Use

1. Nature of the Service

ClassCong is an interactive learning platform for running university courses and educational content. Its aim is to bring course materials, visualization exercises, code execution, quizzes, personal notes, and questions and discussion together in one place.

2. Current Status of the Service

The Service is currently in a preparatory stage. Sign-up and sign-in are fully functional, but learning features such as joining classes, creating courses, and running code are not yet available.

Those features will be released in stages once they are ready. Accounts and data created during the preparatory stage may be reset at the time of the official launch, and notice will be given in advance if that occurs.

3. Creating and Managing an Account

The Service offers social sign-in with a Google or Apple account only. No separate username and password are created.

Users with the same email address are treated as the same person and linked to a single account. For example, if you sign up with Google and later sign in with an Apple account using the same email address, you will be connected to your existing account.

Sign-up is completed only after you have read and agreed to these rules and the Privacy Policy.

You may not share or transfer your account to anyone else, and you are responsible for all activity conducted through your account.

You may withdraw from the Service at any time. The withdrawal procedure is described in the Privacy Policy.

4. User Obligations

The information you provide when signing up must be accurate, and you must not sign up using another person's account or impersonate anyone else.
