If you care about privacy you should use tor/the tor network:
It's free
It can't track you unless someone happens to own your entire route the network, which hopefully isn't happening and would have to a very big actor and would only be a low chance
You can use tor bridges to bypass censorship and detection
You can visit hidden services if you find out their .onion address
You can host hidden services if you find out how to configure tor
You can switch to a VPN if you really want
Has integration into an existing privacy centred browser but can be used with anything that supports sock5 proxies
