Unfortunately many sites ask for more personal information than they need through web forms. If you visit a website using Tor Browser, they don't know who you are or your true location.
Tor only protects applications that are properly configured to send their Internet traffic through Tor.
Tor does not protect all of your computer's Internet traffic when you run it. Use Tor Browser and software specifically configured for Tor Though there are some things you can practice to improve your anonymity while using Tor and offline. Generally it is impossible to have perfect anonymity, even with Tor.
