How to Use Private Browsing on iPhone and Android in the US: Safari and Chrome, Step by Step

You want to look up a gift on a shared phone, check a price without being followed by ads for a week, or sign into a second account without logging out of the first. That is what private browsing is for. It is a mode in Safari, Chrome, and most other mobile browsers that stops your phone from keeping a record of what you do in that window.

What private browsing actually does

When you open a private tab, your browser starts with a clean slate. It does not save your browsing history, it does not keep cookies or site data after you close the tab, and it does not remember what you typed into forms. Each private tab forgets itself when you close it.

That makes it useful in a few everyday situations. On a shared phone, nobody who picks the device up later will see the sites you visited in the private window. When you shop for a gift, the store cannot leave a cookie that follows you around the web with ads for the same product. When a website is acting strangely, opening it in a private tab is a quick way to test whether a saved cookie is the problem, because the private tab loads the site as if you had never been there.

What private browsing does not hide

Here is the part people get wrong. Private browsing only hides your activity from other people who use the same phone. It does not hide you from the internet. Your internet provider and your mobile carrier can still see the websites you visit, and if you are on a work or school network, the network owner can still see your traffic. The websites themselves can still see your IP address and know roughly where you are.

Private browsing does not block trackers on its own, it does not protect you from malware or phishing, and it does not make you anonymous. It also does not hide everything on the phone: a file you download in a private tab stays in your Downloads folder after you close the tab, and bookmarks you save stay saved. If you need real privacy from your network, you need a VPN on top of private browsing.

How to open a private tab in Safari on iPhone

Safari calls it Private Browsing, and the steps are short.

1. Open Safari.

2. Tap the Tabs button in the bottom right, the icon with two overlapping squares.

3. At the bottom of the screen, tap the tab group name, then choose Private.

4. Tap the plus button to open a new private tab. The address bar turns dark, which is how you know you are in a private tab.

5. Browse as usual. When you are done, go back to the Tabs view and tap the X on each private tab to close it.

To lock your private tabs, open Settings, go to Safari, and turn on Require Face ID to Unlock Private Browsing, or Touch ID or passcode on older models. With that on, Safari asks for your face, fingerprint, or passcode before it shows private tabs again after you leave the app. To leave Private Browsing, open the Tabs view again, tap the tab group name, and choose the regular tab group. Your private tabs stay open until you close them, so remember to close them if you hand the phone to someone else.

How to open an Incognito tab in Chrome

Chrome calls the same feature Incognito mode, and it works almost the same way on iPhone and Android. On iPhone, open Chrome, tap the three dots in the bottom right, and tap New Incognito Tab. A new dark tab opens with the Incognito icon. On Android, open Chrome, tap the three dots in the top right, and tap New Incognito tab.

To close an Incognito tab, tap the tab switcher and tap the X, or close all Incognito tabs at once. Chrome can also lock your Incognito tabs: open Chrome settings, go to Privacy and security, and turn on Lock Incognito tabs when you leave Chrome. With that on, Chrome asks for your fingerprint or screen lock before it shows Incognito tabs again.

One difference from Safari: Chrome's Incognito tabs and your normal tabs live in the same tab switcher, separated by a small icon at the top. It is easy to lose track of which is which, so glance at the icon before you type anything sensitive.

When private browsing is worth using

Private browsing is a small tool, and it is best for small jobs. Use it when you share a device, when you want to check a price without leaving a cookie trail, when you need a second signed-in session, or when you are troubleshooting a website that works fine in a private tab but not in a normal one. That last case usually means a saved cookie is the problem, and clearing the site's data or signing out will fix it.

Do not use it as a safety blanket. It will not keep you safe on public Wi-Fi, it will not stop a website from tracking your IP address, and it will not protect you if the phone itself has spyware. For public Wi-Fi, a VPN is the right tool. Use a private tab for things you would not want the next person with your phone to see, and close the tab when you are done.

Frequently Asked Questions

Does private browsing hide my activity from my internet provider?

No. It only stops your browser from saving history, cookies, and form entries on your phone. Your internet provider, your mobile carrier, and the owner of any Wi-Fi network you use can still see the sites you visit. A VPN is needed to hide your traffic from them.

Do I need to close private tabs, or do they close themselves?

You need to close them yourself. Private tabs stay open until you close them, and anyone who opens your browser can see them. Close each tab from the tab switcher when you are done. Files you downloaded in a private tab stay in your Downloads folder.

Is Incognito mode the same as private browsing?

Yes, it is the same idea under a different name. Chrome calls it Incognito, Safari calls it Private Browsing, and Samsung Internet calls it Secret mode. All of them stop the browser from saving your history and cookies, and none of them hide your activity from your network.
