Tor Browser is anonymous in terms of hiding your location and browsing activity — but there are limits. Although they can't see your browsing activity or Tor encrypted data, your ISP can still see that you're using Tor.
Does Tor browser hide your IP?
Tor is a free software program that you load onto your computer (like a browser) that hides your IP address every time you send or request data on the Internet. The process is layered with heavy-duty encryption, which means your data is layered with privacy protection.
Can police track Tor?
There is no way to track live, encrypted VPN traffic.
Using the Tor browser could be suspicious to your ISP and, therefore, to the police. However, you're not going to get in trouble just because it looks a bit suspicious.
