User-Generated Content
DuocQuiz may allow users to voluntarily submit educational content, including quiz questions, examination materials, text descriptions, and related study resources through community contribution features.
Submitted content may be reviewed, moderated, approved, rejected, or removed by administrators before being made available to other users.
Users are responsible for ensuring that any content they submit does not violate applicable laws, intellectual property rights, privacy rights, or the rights of third parties.
By submitting content, users grant DuocQuiz permission to store, review, and display such content within the application for educational purposes.

This app may use third-party services including:

We retain user account data, quiz progress, scores, and related information while the account remains active.
If the account becomes inactive, data may be retained for up to 24 months after the last login, unless the user requests earlier deletion.
Certain limited information may be retained longer where required for legal compliance, fraud prevention, dispute resolution, or security purposes.
Users may request deletion of their account and associated personal data at any time by contacting us at:
