Incognito模式并不能完全隱藏用戶的在線活動，其核心作用是防止Chrome保存瀏覽歷史、Cookie和網(wǎng)站數(shù)據(jù)；但它無法阻止ISP、雇主或網(wǎng)站追蹤用戶行為，也無法完全屏蔽廣告跟蹤或瀏覽器指紋識別技術(shù)。此外，雖然它有助于防止本地設(shè)備上的隱私泄露，例如在公共電腦上避免他人查看到登錄信息，但這些保護僅限于本地會話層面。因此，若追求更高隱私保護，應(yīng)結(jié)合使用廣告攔截工具或隱私導(dǎo)向的瀏覽器擴展。

Incognito mode in Chrome might seem like a foolproof way to browse without leaving traces, but the truth is, it’s more limited than most people think.

The main thing incognito mode does is prevent Chrome from saving your browsing history, cookies, and site data after you close the window. That means if you’re logging into accounts or checking sensitive sites, those won’t be saved on your device. But that’s about where its privacy protections stop.

Incognito doesn’t hide you from the internet

Your internet service provider (ISP), employer (if you're on a work network), or any websites you visit can still track what you’re doing—even in incognito mode. For example, if you search for something on Google while in incognito, Google will still see your IP address and may log that activity if you're signed into your account.

• Your network admin can still see what sites you visit
• Websites can still collect analytics about your visit
• Ads can still track you using techniques that don’t rely on cookies

So if you're trying to hide what you're doing online from someone who has access to the network or the website itself, incognito mode won't help with that.

It doesn’t block tracking tools completely

While incognito mode blocks regular cookies by default once the window is closed, many modern tracking methods don’t rely solely on cookies. Some sites use fingerprinting techniques that identify your browser based on settings like screen resolution, fonts installed, and even plugins. These are harder to block just by opening an incognito window.

• Tracking via browser fingerprint still works
• Ad networks can still get some data through other means
• Extensions you have installed might still run and track

If real privacy is your goal, consider combining incognito with a good ad blocker or privacy-focused browser extensions.

What it does protect against: local snooping

One place where incognito mode actually shines is when you're using a shared or public computer. If you forget to log out of your email or social media, incognito helps make sure the next person won’t find your session already open. Also, things like form autofill data and downloads won’t stick around after you close the window.

• Great for shared devices or quick logins
• Doesn’t leave behind cached files or saved passwords
• Helps avoid accidental exposure to others using the same machine

But again, this is only about keeping your local browsing session private—not hiding your activity from the web at large.

So yeah, incognito mode gives you a bit more privacy, especially locally—but don’t expect it to make you invisible online. Basically, it's useful, but not bulletproof.
