According to Lindahl, Tiktok basically collects all information from the phone, even when the app is closed. It's about what you write, what you surf, what you film or who you call.

- Tiktok is very aggressive when it comes to collecting information, he says.

Tiktok has been accused of sharing the information they collect with Chinese intelligence and security services. And even if it is something that has not been confirmed, you should be careful in your use and also think about whether you should have it on the phone at all.

- If you find that it is not dangerous for me if a company gets access to all personal information, even if it benefits an intelligence service, then you can continue to use it, otherwise you should definitely not do it, he says.
