What Does Incognito Mode Actually Do?
Incognito mode gives you a browser session that leaves no trace on your own device. It is not an invisibility cloak — it changes what your browser stores, not what the network sees.
What it does
- Keeps pages you visit out of your browsing history.
- Deletes cookies and site data when the last private window closes.
- Doesn't save anything you type into forms or search bars.
- Starts you logged out of every site, in a session isolated from your normal one.
What it does not do
- It doesn't hide your IP address or location from websites.
- It doesn't stop your internet provider, employer, school, or router from seeing the sites you connect to.
- It doesn't prevent fingerprinting — sites can often recognize your browser anyway.
- It doesn't delete files you download or bookmarks you save.
- It doesn't protect against malware or phishing.
When Incognito is genuinely useful
- Using a shared or public computer without leaving traces.
- Shopping for gifts without ads spoiling the surprise.
- Signing in to a second account without logging out of the first.
- Testing how a website looks to a logged-out, cookie-free visitor.
FAQ
- Can websites tell I'm in Incognito mode?
- Often, yes. Differences in how private windows handle storage let JavaScript infer private browsing — that's exactly what the checker on this site's homepage demonstrates.
- Is Incognito the same as a VPN?
- No. Incognito changes what your browser stores locally; a VPN changes the route and visibility of your traffic on the network. They solve different problems and can be used together.
