Is Your Browsing History Private?

TL;DR

Whether someone can see your browsing history depends on who they are and how you use the internet. Here’s a guide to protect yourself, covering family members, partners, public Wi-Fi, and potential hackers.

1. Family Members & Shared Computers

1. Separate Accounts: The easiest way is for each person to have their own user account on the computer. This keeps browsing data separate.
   • Windows: Create a new user account in Settings > Accounts > Family & other users.
   • Mac: Create a new user account in System Preferences > Users & Groups.
2. Incognito/Private Browsing: Use your browser’s private browsing mode (e.g., Incognito in Chrome, Private Window in Firefox). This doesn’t hide your activity from the computer owner, but it won’t save cookies, history, or form data locally.
   • Chrome: Ctrl+Shift+N
   • Firefox: Ctrl+Shift+P
3. Browser History Clearing: Regularly clear your browser’s history, cookies and cache. Be aware this doesn’t prevent someone from seeing activity while it was happening.
   • Chrome: Press Ctrl+H, then click ‘Clear browsing data’. Select ‘All time’ for the time range.
   • Firefox: Press Ctrl+Shift+Delete. Select ‘Everything’ for the time range.

2. Partners & Shared Devices

Similar to family members, trust and open communication are key. Technical measures can help, but aren’t a substitute.

1. Strong Passwords: Use strong, unique passwords for all accounts.
2. Browser Profiles: Most browsers allow multiple profiles. Each profile has its own history, cookies, and extensions.
   • Chrome: Click your profile icon in the top-right corner > Add.
   • Firefox: Click your profile icon in the top-right corner > Create a new Profile.

3. Public Wi-Fi

Public Wi-Fi is often unsecure, making it easier for others to see your activity.

1. Use HTTPS: Always make sure websites you visit use HTTPS (look for the padlock icon in the address bar). This encrypts data between you and the website.
2. VPN (Virtual Private Network): A VPN creates an encrypted tunnel for your internet traffic, hiding your activity from others on the network. There are many paid and free options available.
   • Example command to connect using OpenVPN:

     openvpn --config myvpn.ovpn

3. Avoid Sensitive Information: Don’t access sensitive accounts (banking, email) on public Wi-Fi if possible.

4. Hackers & Malware

If your computer is infected with malware, a hacker could potentially see your browsing history.

1. Antivirus Software: Install and regularly update reputable antivirus software.
2. Firewall: Ensure your firewall is enabled. Most operating systems have built-in firewalls.
   • Windows Firewall: Search for ‘Windows Defender Firewall’ in the Start menu.
3. Be Careful with Downloads: Avoid downloading files from untrusted sources.
4. Regular Updates: Keep your operating system and browser up to date, as updates often include security patches.

5. Your Internet Service Provider (ISP)

Your ISP can see all of your unencrypted internet traffic. They may sell this data or use it for targeted advertising.

1. VPN: Using a VPN will hide your browsing activity from your ISP.
