How to hide on the internet

Action: Tape over all your webcams
Who is this for: Everyone — even Mark Zuckerberg!
How difficult is it: Easy peasy lemon squeezy
Tell me more: You can get fancy removable stickers for this purpose (noyb has some nice ones). Or you can go DIY and use a bit of masking tape — on your laptop, your smartphone, even your smart TV… If your job requires you to be on camera, such as for some conference calls, and you want to look a bit more pro you can buy a webcam cover. Sadly locking down privacy is rarely this easy.

Action: Install HTTPS Everywhere
Who is this for: Everyone — seriously do it
How difficult is it: Mild effort
Tell me more: Many websites offer encryption. With HTTPS, people running the network between your device and the server hosting the website you’re browsing can’t see your requests and your internet traffic. But some websites still load unencrypted pages by default (HTTP), which also causes a security risk. The EFF has developed a browser extension that makes sure that you access all websites that offer HTTPS using… HTTPS.

Action: Use tracker blockers
Who is this for: Everyone — except people who like being ad-stalked online
How difficult is it: Mild effort
Tell me more: Trackers refers to a whole category of privacy-hostile technologies designed to follow and record what web users are doing as they move from site to site, and even across different devices. Trackers come in a range of forms these days. And there are some pretty sophisticated ways of being tracked (some definitely harder to thwart than others). But to combat trackers being deployed on popular websites — which are probably also making the pages slower to load than they otherwise would be — there’s now a range of decent, user-friendly tracker blockers to choose from. Pro-privacy search engine DuckDuckGo recently added a tracker blocker to their browser extensions, for example. Disconnect.me is also a popular extension to block trackers from third-party websites. Firefox also has a built-in tracker blocker, which is now enabled by default in the mobile apps. If you’re curious and want to see the list of trackers on popular website, you can also install Kimetrak to understand that it’s a widespread issue.

Action: Use an ad blocker
Who is this for: Everyone who can support the moral burden
How difficult is it: Fairly easy these days but you might be locked out of the content on some news websites as a result
Tell me more: If you’ve tried using a tracker blocker, you may have noticed that many ads have been blocked in the process. That’s because most ads load from third-party servers that track you across multiple sites. So if you want to go one step further and block all ads, you should install an ad blocker. Some browsers like Opera come with an ad blocker. Otherwise, we recommend uBlock Origin on macOS, Windows, Linux and Android. 1Blocker is a solid option on iOS.
But let’s be honest, TechCrunch makes some money with online ads. If 100% of web users install an ad blocker many websites you know and love would simply go bankrupt. While your individual choice won’t have a material impact on the bottom line, consider whitelisting the sites you like. And if you’re angry at how many trackers your favorite news site is running try emailing them to ask (politely) if they can at least reduce the number of trackers they use.

Action: Make a private search engine your default
Who is this for: Most people
How difficult is it: A bit of effort because your search results might become slightly less relevant
Tell me more: Google probably knows more about you than even Facebook does, thanks to the things you tell it when you type queries into its search engine. Though that’s just the tip of how it tracks you — if you use Android it will keep running tabs on everywhere you go unless you opt out of location services. It also has its tracking infrastructure embedded on three-quarters of the top million websites. So chances are it’s following what you’re browsing online — unless you also take steps to lock down your browsing (see below).
But one major way to limit what Google knows about you is to switch to using an alternative search engine when you need to look something up on the Internet. This isn’t as hard as it used to be as there are some pretty decent alternatives now — such as DuckDuckGo which Apple will let you set as the default browser on iOS — or Qwant for French-speaking users. German users can check out Cliqz. You will also need to remember to be careful about any voice assistants you use as they often default to using Google to look stuff up on the web.

Action: Use private browser sessions
Who is this for: Most people
How difficult is it: Not at all if you understand what a private session is
Tell me more: All browsers on desktop and mobile now let you open a private window. While this can be a powerful tool, it is often misunderstood. By default, private sessions don’t make you more invisible — you’ll get tracked from one tab to another. But private sessions let you start with a clean slate. Every time you close your private session, all your cookies are erased. It’s like you disappear from everyone’s radar. You can then reopen another private session and pretend that nobody knows who you are. That’s why using a private session for weeks or months doesn’t do much, but short private sessions can be helpful.

Action: Use multiple browsers and/or browser containers
Who is this for: People who don’t want to stop using social media entirely
How difficult is it: Some effort to not get in a muddle
Tell me more: Using different browsers for different online activities can be a good way of separating portions of your browsing activity. You could, for example, use one browser on your desktop computer for your online banking, say, and a different browser for your social networking or ecommerce activity. Taking this approach further, you could use different mobile devices when you want to access different apps. The point of dividing your browsing across different browsers/devices is to try to make it harder to link all your online activity to you. That said, lots of adtech effort has been put into developing cross-device tracking techniques — so it’s not clear that fragmenting your browsing sessions will successful beat all the trackers.
In a similar vein, in 2016 Mozilla added a feature to its Firefox browser that’s intended to help web users segregate online identities within the same browser — called multi container extensions. This approach gives users some control but it does not stop their browser being fingerprinted and all their web activity in it linked and tracked. It may help reduce some cookie-based tracking, though.
Last month Mozilla also updated the container feature to add one that specifically isolates a Facebook user’s identity from the rest of the web. This limits how Facebook can track a user’s non-Facebook web browsing — which yes Facebook does do, whatever Zuckerberg tried to claim in Congress — so again it’s a way to reduce what the social network giant knows about you. (Though it should also be noted that clicking on any Facebook social plug-ins you encounter on other websites will still send Facebook your personal data.)

Action: Get acquainted with Tor
Who is this for: Activists, people with high risks attached to being tracked online, committed privacy advocates who want to help grow the Tor network
How difficult is it: Patience is needed to use Tor. Also some effort to ensure you don’t accidentally do something that compromises your anonymity
Tell me more: For the most robust form of anonymous web browsing there’s Tor. Tor’s onion network works by encrypting and routing your Internet traffic randomly through a series of relay servers to make it harder to link a specific device with a specific online destination. This does mean it’s definitely not the fastest form of web browsing around. Some sites can also try to block Tor users so the Internet experience you get when browsing in this way may suffer. But it’s the best chance of truly preserving your online anonymity. You’ll need to download the relevant Tor browser bundle to use it. It’s pretty straightforward to install and get going. But expect very frequent security updates which will also slow you down.

Action: Switch to another DNS
Who is this for: People who don’t trust their ISP
How difficult is it: Moderately
Tell me more: When you type an address in the address bar (such as techcrunch.com), your device asks a Domain Name Server to translate that address into an IP address (a unique combination of numbers and dots). By default, your ISP or your mobile carrier runs a DNS for their users. It means that they can see all your web history. Big telecom companies are going to take advantage of that to ramp up their advertising efforts. By default, your DNS query is also unencrypted and can be intercepted by people running the network. Some governments also ask telecom companies to block some websites on their DNS servers — some countries block Facebook for censorship reasons, others block The Pirate Bay for online piracy reasons.
You can configure each of your device to use another public DNS. But don’t use Google’s public DNS! It’s an ad company, so they really want to see your web history. Both Quad9 and Cloudflare’s 1.1.1.1 have strong privacy policies. But Quad9 is a not-for-profit organization, so it’s easier to trust them.

Action: Disable location services
Who is this for: Anyone who feels uncomfortable with the idea of being kept under surveillance
How difficult is it: A bit of effort finding and changing settings, and a bit of commitment to stay on top of any ‘updates’ to privacy policies which might try to revive location tracking. You also need to be prepared to accept some reduction in the utility and/or convenience of the service because it won’t be able to automatically customize what it shows you based on your location
Tell me more: The tech industry is especially keen to keep tabs on where its users are at any given moment. And thanks to the smash hit success of smartphones with embedded sensors it’s never been easier to pervasively track where people are going — and therefore to infer what they’re doing. For ad targeting purposes location data is highly valuable of course. But it’s also hugely intrusive. Did you just visit a certain type of health clinic? Were you carrying your phone loaded with location-sucking apps? Why then it’s trivially easy for the likes of Google and Facebook to connect your identity to that trip — and link all that intel to their ad networks. And if the social network’s platform isn’t adequately “locked down” — as Zuckerberg would put it — your private information might leak and end up elsewhere. It could even get passed around between all sorts of unknown entities — as the up to 87M Facebook profiles in the Cambridge Analytica scandal appear to have been. (Whistleblower Chris Wylie has said that Facebook data-set went “everywhere”.)
There are other potential risks too. Insurance premiums being assessed based on covertly collected data inputs. Companies that work for government agencies using social media info to try to remove benefits or even have people deported. Location data can also influence the types of adverts you see or don’t see. And on that front there’s a risk of discrimination if certain types of ads — jobs or housing, for example — don’t get served to you because you happen to be a person of color, say, or a Muslim. Excluding certain protected groups of people from adverts can be illegal — but that hasn’t stopped it happening multiple times on Facebook’s platform. And location can be a key signal that underpins this kind of prejudicial discrimination.
Even the prices you are offered online can depend on what is being inferred about you via your movements. The bottom line is that everyone’s personal data is being made to carry a lot of baggage these days — and most of the time it’s almost impossible to figure out exactly what that unasked for baggage might entail when you consent to letting a particular app or service track where you go.
Pervasive tracking of location at very least risks putting you at a disadvantage as a consumer. Certainly if you live somewhere without a proper regulatory framework for privacy. It’s also worth bearing in mind how lax tech giants can be where location privacy is concerned — whether it’s Uber’s infamous ‘god view’ tool or Snapchat leaking schoolkids’ location or Strava accidentally revealing the locations of military bases. Their record is pretty terrible.
If you really can’t be bothered to go and hunt down and switch off every location setting one fairly crude action you can take is to buy a faraday cage carry case — Silent Pocket makes an extensive line of carry cases with embedded wireless shielding tech, for instance — which you can pop your smartphone into when you’re on the move to isolate it from the network. Of course once you take it out it will instantly reconnect and location data will be passed again so this is not going to do very much on its own. Nixing location tracking in the settings is much more effective.

Action: Approach VPNs with extreme caution
Who is this for: All web users — unless free Internet access is not available in your country
How difficult is it: No additional effort
Tell me more: While there may be times when you feel tempted to sign up and use a VPN service — say, to try to circumvent geoblocks so you can stream video content that’s not otherwise available in your country — if you do this you should assume that the service provider will at very least be recording everything you’re doing online. They may choose to sell that info or even steal your identity. Many of them promise you perfect privacy and great terms of service. But you can never know for sure if they’re actually doing what they say. So the rule of thumb about all VPNs is: Assume zero privacy — and avoid if at all possible. Facebook even has its own VPN — which it’s been aggressively pushing to users of its main app by badging it as a security service, with the friendly-sounding name ‘Protect’. In reality the company wants you to use this so it can track what other apps you’re using — for its own business intelligence purposes. So a more accurate name for this ‘service’ would be: ‘Protect Facebook’s stranglehold on the social web’.

Action: Build your own VPN server
Who is this for: Developers
How difficult is it: You need to be comfortable with the Terminal
Tell me more: The only VPN server you can trust is the one you built yourself! In that case, VPN servers can be a great tool if you’re on a network you don’t trust (a hotel, a conference or an office). We recommend using Algo VPN and a hosting provider you trust.

Action: Take care with third-party keyboard apps
Who is this for: All touchscreen device users
How difficult is it: No additional effort
Tell me more: Keyboard apps are a potential privacy minefield given that, if you allow cloud-enabled features, they can be in a position to suck out all the information you’re typing into your device — from passwords to credit card numbers to the private contents of your messages. That’s not to say that all third-party keyboards are keylogging everything you type. But the risk is there — so you need to be very careful about what you choose to use. Security is also key. Last year, sensitive personal data from 31M+ users of one third-party keyboard, AI.type, leaked online after the company had failed to properly secure its database server, as one illustrative example of the potential risks.
Google knows how powerful keyboards can be as a data-sucker — which is why it got into the third-party keyboard game, outing its own Gboard keyboard app first for Apple’s iOS in 2016 and later bringing it to Android. If you use Gboard you should know you are handing the adtech giant another firehose of your private information — though it claims that only search queries and “usage statistics” are sent by Gboard to Google (The privacy policy further specifies: “Anything you type other than your searches, like passwords or chats with friends, isn’t sent. Saved words on your device aren’t sent.”). So if you believe that Gboard is not literally a keylogger. But it is watching what you search for and how you use your phone.
Also worth remembering: Data will still be passed by Gboard to Google if you’re using an e2e encrypted messenger like Signal. So third party keyboards can erode the protection afforded by robust e2e encryption — so again: Be very careful what you use.

Action: Use end-to-end encrypted messengers
Who is this for: Everyone who can
How difficult is it: Mild effort unless all your friends are using other messaging apps
Tell me more: Choosing friends based on their choice of messaging app isn’t a great option so real world network effects can often work against privacy. Indeed, Facebook uses the fuzzy feelings you have about your friends to manipulate Messenger users to consent to continuously uploading their phone contacts, by suggesting you have to if you want to talk to your contacts. (Which is, by the by, entirely bogus.)
But if all your friends use a messaging app that does not have end-to-end encryption chances are you’ll feel forced to use that same non-privacy-safe app too. Given that the other option is to exclude yourself from the digital chatter of your friend group. Which would clearly suck.
Facebook-owned WhatsApp does at least have end-to-end encryption — and is widely used (certainly internationally). Though you still need to be careful to opt out of any privacy-eroding terms the company tries to push. In summer 2016, for example, a major T&Cs change sought to link WhatsApp users’ accounts with their Facebook profiles (and thus with all the data Facebook holds on them) — as well as sharing sensitive stuff like your last seen status, your address book, your BFFs in Whatsapp and all sorts of metadata with Zuck’s ‘family’ of companies. Thankfully most of this privacy-hostile data sharing has been suspended in Europe, after Facebook got in trouble with local data protection agencies.

Action: Use end-to-end encryption if you use cloud storage
Who is this for: Dedicated privacy practitioners, anyone worried about third parties accessing their stuff
How difficult is it: Some effort, especially if you have lots of content stored in another service that you need to migrate
Tell me more: Dropbox IPO’d last month — and the markets signalled their approval of its business. But someone who doesn’t approve of the cloud storage giant is Edward Snowden — who in 2014 advised: “Get rid of Dropbox”, arguing the company is hostile to privacy. The problem is that Dropbox does not offer zero access encryption — because it retains encryption keys, meaning it can technically decrypt and read the data you store with it if it decides it needs to or is served with a warrant.
Cloud storage alternatives that do offer local encryption with no access to the encryption keys are available, such as Spideroak. And if you’re looking for a cloud backup service, Backblaze also offers the option to let you manage the encryption key. Another workaround if you do still want to use a service like Dropbox is to locally encrypt the stuff you want to store before you upload it — using another third party service such as Boxcryptor.

Action: Use an end-to-end encrypted email service
Who is this for: Anyone who wants to be sure their email isn’t being data mined
How difficult is it: Some effort — largely around migrating data and/or contacts from another email service
Tell me more: In the middle of last year Google finally announced it would no longer be data-mining the emails inside its Gmail free email service. (For a little perspective on how long it took to give up data-mining your emails, Gmail launched all the way back in 2004.) The company probably feels it has more than enough alternative data points feeding its user profiling at this point. Plus data-mining email with the rise of end-to-end encrypted messaging apps risks pushing the company over the ‘creepy line’ it’s been so keen to avoid to try to stave off the kind of privacy backlash currently engulfing Facebook.
So does it mean that Gmail is now 100% privacy safe? No, because the service is not end-to-end encrypted. But there are now some great webmail clients that do offer robust end-to-end encryption — most notably the Swiss service Protonmail. Really it’s never been easier to access a reliable, user-friendly, pro-privacy email service. If you want to go one step further, you should set up PGP encryption keys and share them with your contacts. This is a lot more difficult though.

Action: Choose iOS over Android
Who is this for: Mainstream consumers, Apple fans
How difficult is it: Depends on the person. Apple hardware is generally more expensive so there’s a cost premium
Tell me more: No connected technology is 100% privacy safe but Apple’s hardware-focused business model means the company’s devices are not engineered to try to harvest user data by default. Apple does also invest in developing pro-privacy technologies. Whereas there’s no getting around the fact Android-maker Google is an adtech giant whose revenues depend on profiling users in order to target web users with adverts. Basically the company needs to suck your data to make a fat profit. That’s why Google asks you to share all your web and app activity and location history if you want to use Google Assistant, for instance.
Android is a more open platform than iOS, though, and it’s possible to configure it in many different ways — some of which can be more locked down as regards privacy than others (the Android Open Source Project can be customized and used without Google services as default preloads, for example). But doing that kind of configuration is not going to be within reach of the average person. So iOS is the obvious choice for mainstream consumers.

Action: Delete your social media accounts
Who is this for: Committed privacy lovers, anyone bored with public sharing
How difficult is it: Some effort — mostly feeling like you’re going to miss out. But third party services can sometimes require a Facebook login (a workaround for that would be to create a dummy Facebook account purely for login purposes — using a name and email you don’t use for anything else, and not linking it to your usual mobile phone number or adding anyone you actually know IRL)
Tell me more: Deleting Facebook clearly isn’t for everyone. But ask yourself how much you use it these days anyway? You might find yourself realizing it’s not really that central to what you do on the Internet after all. The center of gravity in social networking has shifted away from mass public sharing into more tightly curated friend groups anyway, thanks to the popularity of messaging apps.
But of course Facebook owns Messenger, Instagram and WhatsApp too. So ducking out of its surveillance dragnet entirely is especially hard. Ideally you would also need to run tracker blockers (see above) as the company tracks non-Facebook users around the Internet via the pixels it has embedded on lots of popular websites.
While getting rid of your social media accounts is not a privacy panacea, removing yourself from mainstream social network platforms at least reduces the risk of a chunk of your personal info being scraped and used without your say so. Though it’s still not absolutely guaranteed that when you delete an account the company in question will faithfully remove all your information from their servers — or indeed from the servers of any third party they shared your data with.
If you really can’t bring yourself to ditch Facebook (et al) entirely, at least dive into the settings and make sure you lock down as much access to your data as you can — including checking which apps have been connected to your account and removing any that aren’t relevant or useful to you anymore.

Action: Say no to always-on voice assistants
Who is this for: Anyone who values privacy more than gimmickry
How difficult is it: No real effort
Tell me more: There’s a rash of smart speaker voice assistants on shop shelves these days, marketed in a way that suggests they’re a whole lot smarter and more useful than they actually are. In reality they’re most likely to be used for playing music (albeit, audio quality can be very poor) or as very expensive egg timers.
Something else the PR for gadgets like Amazon’s (many) Echos or Google Home doesn’t mention is the massive privacy trade off involved with installing an always-on listening device inside your home. Essentially these devices function by streaming whatever you ask to the cloud and will typically store recordings of things you’ve said in perpetuity on the companies’ servers. Some do offer a delete option for stored audio but you would have to stay on top of deleting your data as long as you keep using the device. So it’s a tediously Sisyphean task. Smart speakers have also been caught listening to and recording things their owner didn’t actually want them to — because they got triggered by accident. Or when someone on the TV used the trigger word.
The privacy risks around smart speakers are clearly very large indeed. Not least because this type of personal data is of obvious and inevitable interest to law enforcement agencies. So ask yourself whether that fake fart dispenser gizmo you’re giggling about is really worth the trade off of inviting all sorts of outsiders to snoop on the goings on inside your home.

Action: Block some network requests
Who is this for: Paranoid people
How difficult is it: Need to be tech savvy
Tell me more: On macOS, you can install something called Little Snitch to get an alert every time an app tries to talk with a server. You can approve or reject each request and create rules. If you don’t want Microsoft Word to talk with Microsoft’s servers all the time for instance, it’s a good solution — but is not really user friendly.

Action: Use a privacy-focused operating system
Who is this for: Edward Snowden
How difficult is it: Need to be tech savvy
Tell me more: If you really want to lock everything down, you should consider using Tails as your desktop operating system. It’s a Linux distribution that leaves no trace by default, uses the Tor network for all network requests by default. But it’s not exactly user friendly, and it’s quite complicated to install on a USB drive. One for those whose threat model really is ‘bleeding edge’.

Action: Write to your political reps to demand stronger privacy laws
Who is this for: Anyone who cares about privacy, and especially Internet users in North America right now
How difficult is it: A bit of effort
Tell me more: There appears to be bipartisan appetite among U.S. lawmakers to bring in some form of regulation for Internet companies. And with new tougher rules coming in in Europe next month it’s an especially opportune moment to push for change in the U.S. where web users are facing reduced standards vs international users after May 25. So it’s a great time to write to your reps reminding them you’re far more interested in your privacy being protected than Facebook winning some kind of surveillance arms race with the Chinese. Tell them it’s past time for the U.S. to draft laws that prioritize the protection of personal data.

Action: Throw away all your connected devices — and choose your friends wisely
Who is this for: Fugitives and whistleblowers
How difficult is it: Privacy doesn’t get harder than this
Tell me more: Last month the former Catalan president, Carles Puigdemont — who, in October, dodged arrest by the Spanish authorities by fleeing to Brussels after the region’s abortive attempt to declare independence — was arrested by German police, after crossing the border from Denmark in a car. Spanish intelligence agents had reportedly tracked his movements via the GPS on the mobile device of one or more of his friends. The car had also been fitted with a tracker. Trusting anything not to snitch on you is a massive risk if your threat model is this high. The problem is you also need trustworthy friends to help you stay ahead of the surveillance dragnet that’s out to get you.

Action: Ditch the Internet entirely
Who is this for: Fugitives and whistleblowers
How difficult is it: Privacy doesn’t get harder than this
Tell me more: Public administrations can ask you to do pretty much everything online these days — and even if it’s not mandatory to use their Internet service it can be incentivized in various ways. The direction of travel for government services is clearly digital. So eschewing the Internet entirely is getting harder and harder to do.
One wild card option — that’s still not a full Internet alternative (yet) — is to use a different type of network that’s being engineered with privacy in mind. The experimental, decentralized MaidSafe network fits that bill. This majorly ambitious project has already clocked up a decade’s worth of R&D on the founders’ mission to rethink digital connectivity without compromising privacy and security by doing away with servers — and decentralizing and encrypting everything. It’s a fascinating project. Just sadly not yet a fully-fledged Internet alternative.
