CPE OJ collects only the basic information needed to create and operate your account, including email, nickname, selected school, login status, submissions, and discussion activity.

Data Use

Account data is used for registration, authentication, leaderboard display, judging submissions, moderation, and service maintenance. We do not ask for unnecessary personal information during registration.

User Conduct

Users may not post obscene, abusive, harassing, discriminatory, infringing, illegal, or system-disrupting content. Attempts to attack, bypass, overload, or misuse the judge system are also prohibited.

Moderation

If an account or content violates these terms, CPE OJ may hide or remove content, suspend access, or cancel account use when necessary to protect users and the service.
