Incognito/Private Browsing: What It Hides and Doesn’t

Quick answer: When you use incognito/private browsing and visit websites, the browser won’t store any history, cookies, website data or forms you complete; this will also be wiped from the browsing window when it is closed. It will not prevent websites, your internet provider, your employer/school or even your accounts which you log into, from seeing what you are doing online. Consider it “private from other users of that device” not “private on the internet.

One Function, Many Names

There may be many synonyms for one Function.

Incognito in Chrome, Edge Private in Edge, Private in Safari and Firefox, are all private browsers versions. To open a private window on desktop, use Ctrl+Shift+P (in Firefox), Command+Shift+N (in Safari), Ctrl+Shift+N (in Chrome) or Ctrl+Shift+N (in Edge on Windows). On a mobile device, you would normally click on the tabs sign and select Private or Incognito.

According to Data Doctors, it’s one of the most misunderstood features in consumer technology. As most people think, it doesn’t hide the things that you do online.

What Incognito/Private Browsing Is (and Isn’t) Doing

It blocks the browser from recording your browsing history, cookies and all data and information you enter into forms on your own computer. Private data won’t be kept on your computer when you close the private window.

This is helpful in particular scenarios:

• Purchasing a gift from the same computer
• [Searching without leaving behind traces on family’s computer]
• Using another person’s computer to log in to a Web site

Chrome also shows a message about what Incognito does and does not do which most people (people who do not understand what Incognito is or does) don’t read.

Who Can Still See You?

So Who Can STILL See You? (Original Comparison)

This is an indicative overview of guidance published and is not a security examination.

Who or what can still tell what you’ve been doing in ‘private mode’?	Answer
Other people on the same device	No, on closing the window
Websites you visit	Yes
Yes, because you identified yourself in the accounts that you log in to (Google, Facebook, Amazon etc.).
Your Internet provider or Wi-Fi operator is YES!Yes is your Internet provider or your Wi-Fi operator.
Your employer or school network	Yes, information can be shared with anyone with your permission.
Your IP address	Visible to the sites you visit
Browser fingerprinting	Often still works

The fingerprinting point is dependant on the type of browser. Some browsers do not yet allow any fingerprinting, whereas Chrome and Edge do not provide protection against this in any way, even on Incognito! There is also no sandboxing in Incognito. Afterwards it wipes off local traces.

The Settlement Confusion

Some of you may have read that Google paid billions over Incognito mode. Sources disagree. In 2024, Google was willing to pay a multibillion-dollar settlement, according to one article. Google had to remove billions of browsing records and update privacy disclosures, but received no monetary payment, says Data Doctors. I would go by the latter description before sharing either statement; looking at a primary news source.

The Goal Matcher

The Goal Matcher (Original Framework)

Link your real-life objective to the appropriate tool. This is an editorial structure for the use of student writers.

Your goal	Incognito/private mode only?	Better approach
Hide history, if it’s a shared device, from family	Yes	Private window
No reputable VPN will be able to do this.
Limit data collection by the websites and advertisers	Partly	Browser that has tracking blocking features and is privacy focused
Do not use activity for employer or school.Do not use personal devices and networks
In order not to be identified, sign in with an account.
Test a site as a visitor on a private window	Yes	Private window

One source suggests that for most of the people, the most practical and non-technical is private browsing plus VPN. But still, both fail to keep your activity hidden from the websites you log into.

For Developers and SEOs: A Practical Use

The private windows is not only a privacy feature but also a diagnostic tool for private window usage. Incognito does not enable extensions by default, and the previous cookie settings are ignored – this is a quick way to gather information about how browsers compare with servers. Use it to:

• See your site from a non-logged-in visitor’s point of view.
• Determine if extension or cookie is responsible for page error
• Review search results without the personalization of your search history

Location and IP address can still produce different results, however, do not consider an Incognito search to be a neutral means of ranking check.

Private Browsing Checklist

A list of questions to use for private browsing.A checklist of questions suitable for private browsing.

Match the Tool to the Threat

Also, before opening up another private window, ask from whom you are hiding. If it’s someone using your device, then incognito/private browsing will suffice. If a website, it’s not, you require another tool or another device. It is about selection of appropriate tool to threat in order to get real privacy.
