What Incognito Mode Actually Does
That's the entire scope of the feature. It is a local data protection tool, not an anonymity tool. The protection is from other people who use your device — not from the internet.
What Incognito Does — and Doesn't — Protect
The gap between expectation and reality is significant.
Local history
URLs you visit aren't saved to your browser's history file. Someone picking up your device won't see where you went.
Session cookies
Cookies from the incognito session are deleted when you close the window. You start fresh next time.
Your IP address
Every website you visit still sees your real IP address. Incognito provides zero IP-level anonymity.
Your employer or ISP
Network-level traffic is fully visible to your internet provider and any network administrator.
Browser fingerprinting
Your screen resolution, fonts, timezone, and hardware identifiers are identical in and out of incognito.
Login-based tracking
If you're logged into Google or Facebook, they track your activity regardless of incognito mode.
The Lawsuit That Made This Concrete
The settlement required Google to delete billions of data records collected from incognito users. The case made clear what technologists already knew: private browsing is a local feature, not a network feature.
When Incognito Mode Is Genuinely Useful
Incognito does have legitimate use cases — they're just narrower than most people think.

What Genuine Browser Privacy Looks Like
If incognito is the wrong tool, what's the right one? Real browser privacy is a combination of behaviours and tools:
- 1Automated cookie deletion: Tracking cookies can't build long-term profiles if they're cleared on a schedule. Broom Cookie Cleaner handles this with configurable intervals — every 30 minutes, hourly, or on browser close.
- 2Profile-based cleaning: Different browsing contexts (work, personal, sensitive research) have different privacy needs. Broom's profile rules let you define exactly what gets cleaned and when for each context.
- 3Clearing all storage types: LocalStorage and IndexedDB can track you even when cookies are blocked. A full browser clean covers all storage layers, not just cookies.
- 4A network privacy layer: A reputable VPN hides your IP and encrypts traffic from your ISP — the thing incognito specifically doesn't do.
- 5Consistent habits over occasional deep cleans: Privacy isn't a one-time event. Automated tools beat manual effort because they're reliable.
Frequently Asked Questions
Common questions about browser cookies answered
Does incognito mode stop Google from tracking me?
No. If you use Google Search in incognito, Google logs your search query tied to your IP address. If you're logged into any Google account, the tracking is even more direct. Incognito only prevents local storage of your history.
Is Firefox's private mode better than Chrome's incognito?
Firefox's private mode includes Enhanced Tracking Protection by default, which blocks many known tracking scripts. It's meaningfully more private than Chrome's incognito, though it still doesn't hide your IP or prevent all fingerprinting.
Should I use incognito mode and cookie cleaning together?
They serve different purposes and complement each other. Incognito prevents local history. Cookie cleaning with Broom prevents cross-session tracking. Using both together gives you local privacy plus network-session privacy.
Can websites detect that I'm using incognito mode?
Some can, yes. Websites can probe for the absence of certain browser APIs, check cache behaviour, or use timing attacks to infer incognito. It's not perfectly invisible even locally.
