To stay private on a shared device, use a private window, sign out afterwards, then clear history, cookies, autofill and downloads. Turn off site notifications and check the recent-apps list. Remember that private mode does not hide activity from your internet provider, school or workplace network, so it only protects against people using the same device.
What are you protecting against?
Privacy advice only works when you know who you are protecting against. On a shared device, the usual worry is another person who picks up the same phone, tablet or computer and sees what you did. That is a different problem from tracking by networks or advertisers.
The steps below mainly stop people who share your device from finding traces. They do not make you anonymous online, and they will not hide anything from a network owner such as a school, employer or internet provider.
Keep that limit in mind and you will choose the right tools.
Step one: use a private window
A private or incognito window does not save browsing history, cookies or form entries once you close it. That makes it the easiest first layer, and it is better to start in one than to clean up afterwards.
Open it before visiting the site, and close the whole window when you finish, not just a single tab. On a phone, check that no private tabs are left sitting in the tab switcher.
Private mode does not remove files you download, bookmarks you create, or screenshots you take. Those stay on the device, so avoid creating them.
Step two: clear what is left
If you forgot to use a private window, you can clear the traces by hand. Menu names differ between browsers, but the same four items matter.
- Open the browser's history or privacy settings.
- Clear browsing history for the right time range.
- Clear cookies and site data, which also logs you out.
- Clear cached images and files, then check the downloads list.
Be aware that clearing everything will also sign you out of other sites you use. If that is a problem, many browsers let you remove history for a single site only.
The places people forget
History is not the only place a visit leaves a mark. These are the usual leftovers.
| Leftover | Where it hides | Fix |
|---|---|---|
| Search suggestions | Address bar | Clear history and autofill |
| Saved passwords | Browser password list | Delete the entry |
| Notifications | Lock screen banners | Block site alerts |
| Downloads | Files folder | Delete them |
| Recent apps | App switcher | Swipe the browser away |
Cloud sync can undo your work
Many browsers sync history across your phone, tablet and laptop through a signed-in account. If so, clearing history on one device may leave a copy on another, or a family member may see it on a device that shares the same account.
Check whether sync is on, and either pause it or clear history from the synced account page. Also look at any family sharing feature that shows activity reports, since those summaries can reveal visited sites.
On a family computer, the cleanest answer is a separate user profile with its own password.
A note for parents
This section is for parents and carers, who often need the opposite skill: finding out what happened on a device a child uses. Browsing history, downloads and notification banners are the first places to look, and they only help if the child has not cleared them or used a private window.
That is why checking history alone is a weak safeguard. It works better alongside device controls such as Screen Time or Family Link, a family-safe DNS filter and a relaxed conversation. Tell children that clearing history is not a crime, but that you would like them to tell you if something upsetting appears.
Shared family tablets are best set up with a separate child profile, so adult sites are never one tap away.
What cannot be hidden
No local cleaning step affects your network. A school, employer or internet provider can generally see which site names you reach, and a family router with a filter may keep logs. Advertisers can still recognise you through trackers while the page is open.
A content blocker and blocking third-party cookies reduce that trail, and a trustworthy, paid VPN service may change who sees your traffic, though it brings its own trade-offs and may break workplace rules. Free VPN apps are a privacy risk of their own.
If you notice a copycat site or a scam, report it via the report page.
Key takeaways
- Private windows only protect against other people using the same device.
