If you use a VPN that doesn’t properly encrypt your internet traffic then yes, you can be traced. However, the best VPNs for California make this virtually impossible. By using the highest level of encryption and security features such as a kill switch and DNS leak protection, your actual IP address and location (and your identity) are hidden. VPNs such as NordVPN and Surfshark even offer Double VPN servers for an extra layer of encryption.
