Why are you even worried about this? WiFi bills just list the amount of data used, the duration of your internet connection, and sometimes device names. They don’t show your browsing history. That private stuff is only accessible by your ISP (Internet Service Provider), not on a bill. If you’re paranoid about someone tracking your history, use a VPN or even the Tor browser to encrypt your data. But honestly, unless someone’s hacking into your network or has physical access to your router, you should chill out.
Sure, some ISPs keep logs of your data. Most regular folks aren’t gonna have access to that unless there’s some legal investigation or something. You might see ‘NetSpot’ or ‘GlassWire’ thrown around as tools, but they mainly help monitor network traffic on a security level – not to police your browsing habits.
If you’re REALLY that concerned, switch ISPs, but good luck finding any that don’t keep logs. They all do to some extent. Also, using these tools can slow down your connection or mess with network settings. So pick your poison.
