Private browser sessions and remaining records

What private browsing hides and what can remain visible

Incognito, Private Browsing and InPrivate limit some local browser records while leaving separate website, network, download and account activity.

Conceptual illustration

Incognito limits a browser session on the device

Google says Chrome Incognito starts a separate session that ends when all Incognito windows close. Cookies and site data can exist during that session and are removed afterward. Saved bookmarks, reading-list items and downloaded files remain available outside it. Google: Incognito local records and network limits

Websites and networks have a separate view

Google says Incognito does not change collection by visited websites and their services. Sites, employers, schools or internet providers may still observe activity. A private window should not be interpreted as invisibility from a signed-in service or the organization managing the network. Google: Incognito local records and network limits

Firefox describes exceptions for deliberately saved items

Mozilla says private-session cookies are separate from regular cookies and discarded when the last private window closes. The guide explicitly says newly saved passwords, bookmarks and downloaded files remain. It also says Private Browsing does not make a user anonymous to websites, an employer or an internet provider.

An InPrivate window can use existing profile information

Microsoft says Edge InPrivate can access favorites, passwords and form-fill data from the launching profile and run permitted extensions. Edge cannot prevent those extensions from saving browsing history. Sites can still request precise location using that profile's permission settings. Closing all InPrivate windows clears specified session data while favorites and downloaded files remain. Microsoft: InPrivate records, extensions and managed restrictions

Safari adds privacy protections within its documented scope

Apple says Safari Private Browsing does not remember visited pages, search history or AutoFill information. It describes blocking known trackers, removing identifying tracking from URLs and additional fingerprinting protections. Those are described protections, not a claim that every website or network record disappears. Apple: iPhone private tabs and local browsing records

Locking a private tab is different from closing it

Apple's Locked Private Browsing feature is designed to keep private windows open while restricting access when stepping away. Unlocking uses device authentication. The feature starts with iOS and iPadOS 17 and Safari 17 on supported Macs. Audio or video playback and an unloaded page are documented exceptions to automatic locking.

Managed-device restrictions can still apply

Microsoft says organizations can disable InPrivate through policy and that family activity-reporting or filtering settings can make it unavailable. Private mode also does not provide extra protection from malicious sites or additional ad blocking. Microsoft: InPrivate records, extensions and managed restrictions
