What's going on?​

The social platform TikTok, developed and operated by the Chinese company ByteDance, is one of the most popular applications in its category worldwide - it has over a billion downloads only in the Google Play Store. It is not different in the Czech Republic - data shows that there are currently around two million active users in the Czech Republic.

In addition to this duty, think about your information security and the protection of your privacy, as TikTok significantly violates both. Protecting your privacy is essential because TikTok may not be the only app that can invade your privacy. Therefore, it also depends on the other services and applications you use and your behavior.
