How to protect your privacy online

Practical, easy steps and privacy-preserving apps to protect your personal information online and take control of your digital life.

Summary

  • Privacy-first browsers, encrypted messaging, and email aliases keep your data from being collected as you browse.
  • A few simple settings changes, like limiting location tracking or rejecting cookies, cut off invisible tracking at the source.
  • Data brokers sell your personal information, but where the law gives you a right to opt out, you can get your records deleted without paying anyone.
  • Privacy-preserving alternatives exist for nearly every app, from email to search, notes to maps, so protecting your data doesn't mean sacrificing convenience.

Anyone can make proactive choices online to protect personal information. Secure your digital footprints by using privacy-preserving software, adjusting device preferences, and submitting legal data deletion requests.

The strategies below are a starting place to protect your privacy online and mitigate tracking across standard web environments.

Use online privacy tools

You can protect your personal information online by switching from standard web tools to privacy-preserving alternatives built to collect less data.

The easiest place to start is your browser, and it is a change nobody else has to make with you. Roughly seven in ten people browse with Chrome[1] and more than nine in ten searches go to Google[2], both built by an advertising company and designed for tracking.

Being the most popular browser does not make Chrome the best one. On independent privacy testing it is among the weakest of the major browsers, and there are plenty of alternatives worth a look.

Change your default search engine

Your search history is the most revealing log you generate: what you buy, who you look up, what symptoms you search for. Point your default at an engine that does not build a profile out of it, like Brave Search or DuckDuckGo.

Block ads and invisible trackers

Scripts that follow you between unrelated sites are what assemble a profile of your habits. Blocking them is automatic in Brave. On any other browser add uBlock Origin, and set the browser itself to block third-party cookies.

Use end-to-end encrypted messaging

Ordinary SMS is readable by your carrier and by anyone who can compel them. End-to-end encrypted apps, like Signal, keep the contents between you and the person you are talking to. Not everyone has to switch at once: install one and you will usually find some contacts already there, and those conversations can move first.

Move to encrypted email

Most free mailboxes are paid for by scanning what arrives in them. Providers like Proton Mail and Tuta encrypt your mail at rest, so the company holding it cannot read it, and both will import an existing inbox when you move.

Give every service its own address

One address used everywhere is what lets data brokers and breach databases stitch your accounts into a single profile. Alias services, like SimpleLogin, hand each site a separate address you can switch off the moment it starts attracting spam.

Stop signing in with Google or Facebook

Every "Sign in with Google" button tells Google which services you use and when, and ties all of those accounts back to one identity. Sign up with an alias instead and let a password manager, like Bitwarden, fill the login in one click: the same convenience, and no shared identifier linking everywhere you have an account.

3 Privacy Fixes Most People Never Make

Naomi Brockwell walks through the three switches with the biggest privacy payoff, email, messaging, and browser, and makes the case that you do not have to change everything at once.

Optimize privacy settings

Secure software functions best when you update device and app settings to mitigate the sharing of location and background data with hardware manufacturers.

Audit your device settings

Review privacy menus on your smartphones, tablets, and computers. Turn off location tracking for apps that do not strictly require it and limit diagnostic data sharing with manufacturers.

Global Privacy Control (GPC)

GPC sends an automatic do-not-sell-or-share signal to every site you visit, and under California's CCPA and laws in states including Colorado and Connecticut it has to be honored. Brave and DuckDuckGo send it by default and Firefox can be set to. Chrome and Safari do not send it at all, so there it takes an extension.

Evade cookie traps

Websites use confusing layouts, so-called dark patterns, to make handing over everything the easy path. Take the extra moment to find "Reject All" or "Manage Preferences". Rejecting is not a paywall: the page still loads, and the site still works.

Reject cookies by default. Declining typically takes one click, and the page loads exactly the same.

Privacy-default apps

Day-to-day replacements for the tools most people already use, picked because they are built to collect as little about you as possible. Which of them matter depends on what you are protecting, and from whom.

What a VPN can do, and what it cannot

A VPN does not make you anonymous

It changes who can watch you. Your internet provider and the network you are on lose sight of where you are going, and the VPN company gains it. You are moving trust, not removing it.

The distinction matters. A VPN genuinely solves some problems and does nothing at all about others, and the marketing rarely separates the two.

What a VPN doesWhat it does NOT do
Hides which sites you visit from your internet provider and from the network you are onHide them from the VPN company, which now sees all of it instead
Replaces your IP address, so sites cannot place you by location or tie separate visits to one householdMake you anonymous to any site you sign in to
Protects you on networks you have no reason to trust, like public Wi-FiAdd encryption that HTTPS is not already providing
Lets you appear to be somewhere else, which helps when a service is blocked where you areStop browser fingerprinting, cookies, or tracking tied to your accounts

Because the operator sees everything your provider used to, its honesty is the entire product. That is why free VPNs are so often the worst offenders: running servers costs money, and when a subscription is not paying for them, your browsing is.

Properly auditing a VPN is slow, expensive work, which is why very few earn a recommendation. What to look for:

  • Published ownership and jurisdiction, so you know who is actually holding your traffic and which government can ask them for it.
  • A no-logs claim an independent auditor has tested, rather than one asserted on a marketing page.
  • Signup that never asks who you are, and a way to pay that is not tied to your identity.
  • A track record: how the company behaved the last time it was subpoenaed, seized, or breached.

Tor, a volunteer-run alternative

Tor can do some of what a paid VPN does, for free, with no company in the middle. Traffic is relayed through three volunteer-run nodes, and no single one of them knows both who you are and where you are going, so there is no operator holding a log to sell or to be forced to hand over.

Tor comes with honest trade-offs. It is slower, some sites block it outright, exit nodes can be run by anyone including governments, and sophisticated observers can still correlate traffic by timing. It is still a strong option for ordinary private browsing, but not for logging in or shopping: signing in tells the site who you are, and hostile exit nodes have been caught stripping HTTPS to steal what passes through.

Tor works better the more ordinary people use it. Every additional user makes the crowd larger and every individual in it harder to pick out, and that crowd is what protects the journalists, activists, and people escaping abuse who rely on it. Everyday browsing adds to it.

Apple Private Relay, a low-barrier option for millions

On Apple hardware, iCloud+ includes Private Relay, which sends Safari traffic through two separate relays so that neither Apple nor the site you are visiting can see both who you are and what you are loading. It covers Safari only, is an Apple service on Apple's terms, and it is no substitute for Tor if you are genuinely at risk. It is, however, a significant improvement over unprotected Chrome, is already sitting on hundreds of millions of devices, and switching it on takes one toggle.

Organizations defending your privacy

Privacy online is not only a question of which apps you install. These organizations research surveillance, litigate against it, and teach people how to protect themselves.
