Keep your private life off the work computer

You use the laptop your job gave you, or a computer at school, for a few things that are nobody’s business but yours. Or you are about to share your screen in a meeting and cannot remember what is open.

Assume your employer or school can see what you do on its computers and network, and keep anything private on your own device.

Many people say to assume there is no privacy on company hardware or networks: IT can watch activity, read logs or inspect the device. The rest of this page is about what that means for your private things, how closely anyone really looks, and how to stop your own screen giving you away in a meeting.

What is visible, and to whom

Some people say work machines often carry monitoring software, and the network keeps logs that can show your screen and the sites you look up. One person says the agreement you sign when you accept a company device usually allows the monitoring, often buried in small print. In the UK, the Information Commissioner’s Office says employers must make sure workers know how and what personal information they collect when they monitor, and must do it lawfully and fairly. In the US the rules differ from state to state, and this page does not cover them.

How closely anyone looks is an open argument, set out below the main text. The advice at the top does not depend on who wins it, because both sides say the logs exist.

Nobody watching does not mean nothing is recorded. Some people who answered “nobody cares enough to watch me” said automated systems flag unusual activity and logs are reviewed when a problem or an audit comes up. One person says some systems email HR when someone’s usage crosses a threshold. Another says a manager can ask IT for your browsing records. Another says logs are reviewed in disputes and firings. And one person puts it this way: assume IT management can see all of it, because logs exist even when nobody is watching live. Some people say penalties range from instant dismissal for explicit material to an informal warning, or having the laptop wiped, for something minor like using a lot of bandwidth.

Keep the private things on your own device

Many people say to use a different device, or at least a separate browser profile, for anything sensitive and personal, so it never touches work data. One person says to browse privately on a personal phone using its own mobile data, not the company Wi-Fi, because the company network cannot see traffic that never passes through it.

A personal phone on the company Wi-Fi is not hidden. Some people say it can still be identified by details like its device name or hardware address, and that installing the company’s management app on a personal phone makes it company-managed in effect. Renaming a phone to something generic does not reliably help: people who answered that idea said IT can still match the activity to you by other means, or simply because the company owns the network.

Two more ways private things end up on the work side. One person says that if you log in to a work account on a personal device, or sync a browser between home and work, that can expose personal history even off the work network. Another says logging in to a personal email account on a work computer gives the employer access to the mail and data. And one person says not to keep personal files in folders that are copied to company servers.

Some people say not to set up your own VPN on a company network to get around any of this. They say it creates security problems and may be read as an attempt to leak files, and one person says it can trigger a security alert.

Do you need a separate account?

Some people build a separate user account or browser for the work side and keep the personal one apart. Others say the cure is behaviour, not tools: do not use the work laptop for non-work things at all. What decides it, they say, is company policy and your own discipline. The tools assume personal use will happen; the policy answer says it should not. One person adds that a separate account is often impossible anyway, because employers restrict admin rights and tie logins to a single ID.

If the thing you want to keep private is explicit or sensitive material, one person says do not view it on a work device at all, because it may be logged and used against you in a dispute.

Before you share your screen

Many people say to use a user account made only for work or presentations, so no personal files, history or notifications can show. Some say the simple habits help: close tabs after use, keep work and home browsing in different browsers, and carry the presentation on a thumb drive. One person warns that autofill can still suggest earlier searches when you type an address, even under a separate account, and another pointed out that clearing the cache is not the same as clearing your history, and that if you are signed in to a browser account that syncs, the search history stays in the cloud account either way. One person says to close messaging apps and clear active windows before you hand a laptop to IT.

If an exam is monitored by software

If your school makes you sit an exam under monitoring software on your own computer, one person says to keep sensitive data such as banking and medical files off the machine you use, because the software may have wide access. Another says sitting the exam at the school itself avoids remote monitoring entirely. Some people suggest running the exam inside a virtual machine, to hold the software at arm’s length. Some people answered that modern monitoring software can detect that, and that a school may treat it as cheating and fail you. This page does not teach that route.

Who this page is not for

If the person watching your devices is someone at home, such as a partner who controls your phone and computer and you are afraid of them, the tricks on this page are not the answer. In the US, the National Domestic Violence Hotline is 1-800-799-7233, any hour, or text START to 88788. In the UK, the National Domestic Abuse Helpline, run by Refuge, is 0808 2000 247, free and open around the clock. The Support section of this site also has a page called Browsing privately.

If you own the computer and the company wants it for work, the rules about what it may do depend on your agreement and where you live. This page does not cover them.
