"Which Vietnamese city should you live in?" or "What kind of student are you?" These fun quizzes on social media are hard to resist. Sharing your results with friends is a popular way to connect and have a laugh. However, behind the entertaining questions, there is often a hidden purpose that many users are not aware of.

When you start a quiz, it often asks for your permission to access your profile. By clicking "agree," you might be allowing the app to see more than just your name.

While it might seem harmless, this collection of data is a serious business and may even be sold to other companies.

This doesn't mean you must stop using the internet for fun. The key is to be a smart digital citizen. Before you take that next exciting quiz, take a moment to read what permissions it is asking for. Protecting your personal information online is an important skill for everyone in the modern world.
