What Your Web Browser's Incognito Mode Really Does

On February 25, 2026  By newsroom   Topic: Technology Buyers Guide

Incognito mode can be a helpful privacy tool, but it has its limits. Here's what it does and doesn’t do:


What Incognito Mode Does

Deletes Local Data
- Browsing history and cookies are erased after you close the window.
- Helpful for keeping your activity private on shared devices.

Reduces Tracking
- Prevents advertisers from using cookies to show targeted ads based on your searches.
- Some browsers (e.g., Firefox, Safari) also protect against fingerprinting, which identifies users via their device details.

Supports Temporary Logins
- Ideal for checking email or accounts on public devices. Once the session ends, your login data isn’t saved.

Private Searches
- Useful for shopping for surprise gifts or browsing sensitive topics without leaving a trail.


What Incognito Mode Doesn’t Do

Doesn’t Hide Activity from Networks or Websites
- Your ISP, employer, or website servers still see your activity.
- Using your employer's WiFiThey’ll know the sites you visited.

No Malware Protection
- It doesn’t block malicious downloads or protect you from phishing attacks.
- Keep software updated and consider anti-malware software for security.

Doesn’t Delete Downloaded Files
- Files saved during an incognito session remain on your device. Delete them manually if needed.

Limited Privacy from Big Platforms
- Google, Facebook, and similar platforms can still track you if you’re logged in to their services.


When to Use Incognito Mode

  • Browsing on Shared Devices: Keeps your activity hidden from others who use the same device.
  • Shopping or Research: Avoid targeted ads or keep searches private.
  • Quick Logins: Temporary access to accounts on public or borrowed devices.

Best Practices for Better Privacy

  • Use a VPN for more robust anonymity.
  • Disable read receipts and log out of accounts before browsing privately.
  • Regularly clear downloads and cached files on your device.

Incognito mode is a helpful tool for local privacy, but it’s not a cure-all for online anonymity. Use it wisely!
