Is incognito mode really useful?

Many users open an incognito window believing that it makes them anonymous online. Although this mode helps keep browsing activity off your device, it does not prevent every form of tracking. To understand whether it is useful, it is important to know what it actually does.

How does incognito mode work?

Opening an incognito window starts a separate browsing session. Cookies and site data are stored temporarily while you browse and are removed when you close all incognito windows. Chrome also does not retain the session’s browsing history or information entered in forms. However, downloaded files and saved bookmarks remain on your device.

This makes incognito mode useful when you want to keep browsing history off a shared device or sign in to a separate account without signing out of your usual one. It does not hide your IP address or prevent websites, your employer, or your internet service provider from observing activity they could otherwise see.

How do cookies affect your privacy?

When you visit a website, it may store small files called cookies in your browser. These can remember your preferences, keep you signed in, or help measure how you use the site. Some cookies also support tracking across websites and contribute to profiles used for targeted advertising.

Returning to a website does not automatically reveal all your personal information. However, tracking companies can combine browsing activity with other information to infer your interests, preferences, and potentially sensitive characteristics.

How can you reduce cookie-based tracking?

• Reject non-essential cookies when a website offers that choice, and review your browser’s cookie and tracking protection settings.
• Use tracker-blocking extensions that block third-party tracking code and cookies.
• Use incognito mode when you want session cookies and browsing history removed after you close all incognito windows. Remember that websites can still track activity within that session, particularly if you sign in.

Can a VPN provide additional protection?

A VPN can complement incognito mode by masking your public IP address and encrypting traffic between your device and the VPN server. This helps protect the connection from inspection by others on the local network.

Incognito mode is therefore useful, but its main purpose is local privacy – not online anonymity. Use it alongside appropriate browser settings and other security tools, such as VPNs or tracker blockers, depending on what you want to protect.
