5. Children's Privacy (COPPA & Local Law Compliance)

InterVoca is an educational service designed for international school students.
We comply with the Children's Online Privacy Protection Act (COPPA) in the United States, the Personal Information Protection Act (PIPA) of the Republic of Korea, and similar child privacy regulations in other jurisdictions.

• In accordance with the Personal Information Protection Act of the Republic of Korea, children under the age of 14 may not create an account independently; a parent or legal guardian must create and manage the account on their behalf. This standard also satisfies the under-13 protection requirements of the U.S. COPPA.
• If we become aware that we have inadvertently collected personal information from a child under 14 (or under 13 in the United States) without proper parental oversight, we will take steps to delete that information promptly.
• Children's personal information is not used for targeted advertising or marketing purposes.
• Parents or legal guardians may request to review or delete their child's personal information.
