Incognito mode mainly hides browsing activity from other people who use the same device after you close the private session. It does not hide your activity from websites you visit, accounts you sign in to, or network operators such as an employer, school, or internet provider. Downloads and bookmarks can remain on the device.
What Incognito mode hides on your device
Private browsing limits what the browser keeps in its ordinary local history and site data. Chrome says it does not retain a record of sites visited or site data after the Incognito session ends. Firefox says it clears session history, cookies, and site data after all Private Windows are closed. The details differ by browser, but the main purpose is local privacy on the device.
That can help keep a later user of the same browser from seeing your private-session history in its normal history list. It is not a guarantee that every trace has been securely erased from the device.

What Incognito mode does not hide
Websites you visit
A website can still receive information about your visit while you browse privately. If you sign in to a service, the service can associate activity with that account; Google notes that a site can know you are browsing and track activity from the point you sign in. Incognito changes what the browser retains locally, not what a website can receive.

Your internet provider, employer, or school
Incognito is not a network anonymity tool. Google Chrome Help and Mozilla both warn that employers, schools, and internet service providers may still be able to observe information about visited pages. That does not mean every provider or organization monitors or stores every visit; private mode simply does not prevent that possibility.
Do downloads, bookmarks, and cookies remain?
- Downloads: Downloaded files remain on the computer in Chrome and Firefox. Firefox removes the entries from its download list after the Private Window session, but the downloaded files themselves remain.
- Bookmarks: Bookmarks saved during private browsing remain on the device.
- Cookies and site data: Chrome says this data is not retained after the Incognito session ends. Firefox says it clears cookies and site data after all Private Windows close.
Closing the private session therefore clears specified browser records, but it does not undo files you saved or bookmarks you created.

How Chrome and Firefox differ
| Behavior | Chrome Incognito | Firefox Private Browsing |
|---|---|---|
| History and site data | Chrome says visited-site records and site data are not retained after the Incognito session ends. | Firefox says session history, cookies, and site data are cleared after all Private Windows close. |
| Downloads and bookmarks | Downloaded files and bookmarks remain on the device. | Downloaded files and bookmarks remain; download-list entries are removed from the Firefox library after the session. |
| Tracker protections | The cited Chrome guidance does not establish a comparable default tracker-blocking behavior. | Firefox says Private Browsing blocks third-party cookies and content trackers by default. |
| Visibility to websites and network operators | Websites, signed-in services, and network operators may still observe activity. | Websites and network operators may still observe activity. |
These are vendor descriptions of their respective browser features, not a claim that every browser or configuration behaves the same way. The available Apple guidance here is not sufficient to make a comparable Safari-specific claim.

- Useful: reducing the browsing history and site data left in the browser for the next person using the same device.
- Not enough: keeping a website from receiving your visit, separating activity from an account after you sign in, or preventing an employer, school, or internet provider from potentially observing activity.
Google Chrome Help summarizes the distinction: “While Incognito can help keep your browsing private on your device, it doesn’t make you invisible.”
