Facebook has hit the headlines in recent weeks over its handling of your private data, and now the shocking extent of information held by Google has been revealed.
In a series of tweets, one IT expert has laid out exactly what the search giant knows about him, dating back to 2008, which he describes as ‘preposterous’.
It ranges from every place he visited in the past year to every website he clicked on, and even contained files deleted from his Google Drive cloud storage account.
The news comes in the wake of the Cambridge Analytica scandal, which saw a Trump-affiliated firm obtaining data on 50 million unsuspecting Facebook users.
This information was used to target voters in the US, based on psychological profiling, with political adverts spreading disinformation.

Web developer Dylan Curran, based in Waterford, Ireland, decided to download both his Facebook and Google archives on Saturday.
The data held by the world’s most popular social media site was fairly large, at around 600mb, equivalent to roughly 400,000 Word documents.
But this paled in comparison to Google’s data file, which was 5.5gb, almost ten times larger. This is around the same size as three million Word documents.
Sharing his findings on Twitter, in a post retweed more than 150,000 times, he said: ‘Want to freak yourself out? I’m gonna show just how much of your information the likes of Facebook and Google store about you without you even realising it.’
Mr Curran found that Google was constantly tracking his location in the background, including how long it took to travel between various points.
It also held details about his hobbies and interests, as well as guesses on his possible weight and income.
Speaking to NBC News, he said: ‘It’s wrong to trust any entity that big with so much information.
‘They’re just trying to make money,’ and at some point, ‘someone is going to make a mistake.’
Read on to find out exactly what Google knew, and how you can find out more about the specific types of data they have on you.

Where you’ve been
If you have location tracking turned on via your smartphone, tablet or other connected device and they’re switched on, Google stores details of everywhere you’ve been.
For Mr Curran, this included his travels around Ireland over the previous 12 months, including journey times between towns and cities.
When MailOnline decided to drill down into this data, it revealed a surprising level of detail.
As well as foreign travel, it included the name of a number of pubs visited, the length of time spent in them, and the route taken to get home.

WHAT IS THE CAMBRIDGE ANALYTICA SCANDAL?
Communications firms Cambridge Analytica has offices in London, New York, Washington, as well as Brazil and Malaysia.
The company boasts it can ‘find your voters and move them to action’ through data-driven campaigns and a team that includes data scientists and behavioural psychologists.
‘Within the United States alone, we have played a pivotal role in winning presidential races as well as congressional and state elections,’ with data on more than 230 million American voters, Cambridge Analytica claims on its website.
The company profited from a feature that meant apps could ask for permission to access your own data as well as the data of all your Facebook friends.
The data firm suspended its chief executive, Alexander Nix (pictured), after recordings emerged of him making a series of controversial claims, including boasts that Cambridge Analytica had a pivotal role in the election of Donald Trump
This meant the company was able to mine the information of 55 million Facebook users even though just 270,000 people gave them permission to do so.
This was designed to help them create software that can predict and influence voters’ choices at the ballot box.

This information is said to have been used to help the Brexit campaign in the UK.
Everything you’ve ever searched for
Google, somewhat unsurprisingly for a search engine, records everything you search for on the internet.
What might shock you, however, is that this is kept on file even when you delete your history.
Mr Curran’s log contained 90,000 different entries, even showing images he downloaded and websites he accessed.
This included banned torrent site ThePirateBay, which he mentions in his tweets to illustrate how much damage this information could do if it becomes public.

WHAT HAS FACEBOOK DONE TO ADDRESS PRIVACY CONCERNS?
Facebook is giving its privacy tools a makeover as it reels from criticisms over its data practices and faces tighter European regulations in the coming months.
The changes won’t affect Facebook’s privacy policies or the types of data it gathers about its users.
But the company hopes its 2.2 billion users will have an easier time navigating its complex and often confusing privacy and security settings.

Facebook says it’s trying to make the controls easier to find and to give users a simpler way to access and download the data it collects on them.
The announcement follows revelations that Trump-affiliated consulting firm got data on millions of unsuspecting Facebook users.
Facebook is also facing criticism for collecting years of data on call and text histories from Android users.
In a written statement, Erin Egan, vice president and chief privacy officer, policy, and Ashlie Beringer, vice president and deputy general counsel, said: ‘Last week showed how much more work we need to do to enforce our policies and help people understand how Facebook works and the choices they have over their data.

Among the changes, Facebook is making data settings and tools easier to find, is introducing a new privacy shortcuts menu, and is adding tools to find, download and delete your Facebook data
‘We’ve heard loud and clear that privacy settings and other important tools are too hard to find and that we must do more to keep people informed.
‘We’re taking additional steps in the coming weeks to put people more in control of their privacy.
‘Most of these updates have been in the works for some time, but the events of the past several days underscore their importance.’

HOW CAN YOU STOP FACEBOOK’S ADVERTISING NETWORK TRACKING YOU ONLINE?
Part of what makes companies like Facebook and Google so valuable, is that they oversee vast treasure troves of user data which can be of huge benefit to brands.
For advertisers, it means they’re more likely to get a higher click-through rate on their advertisements, boosting the effectiveness of their campaigns.
For users, it means forfeiting personal information to a variety of unknown sources.
Thankfully, there are a number of steps that can be taken to prevent Facebook’s ad partners from following you as you browse the internet on your phone or desktop computer.
Changing your settings on your smartphone or tablet
If you own an iPhone or iPad, the steps to block targeted adverts are relatively simple.
Go to Settings, tap Privacy and then scroll down to click on Advertising.
From there, swipe the ‘Limit Ad Tracking’ button.
If you choose to leave the ‘Limit Ad Tracking’ feature off, that means that advertisers can track your browsing behavior by assigning your device a unique ID number, or a Identifier For Advertising.
In turn, it will be harder for ad technology companies to track your browsing behavior.
If you own an Android phone or tablet, the process is very similar.
Open up Settings, navigate to Accounts and Sync, select Google, then Ads and finally, select ‘Opt Out of Interest Based Ads.’
Changing your browser settings
If you’re browsing the internet on Google Chrome, go to ‘Settings’ in the right-hand dropdown menu.
From there, click on ‘Show advanced settings,’ then select Privacy.
Finally, click on ‘Send a do not track request with your browsing traffic.’
A popup on Chrome further explains what this means: ‘Enabling Do Not Track means that a request will be included with your browsing traffic.
‘Any effect depends on whether a website responds to the request, and how the request is interpreted.’
‘For example, some websites may respond to this request by showing you ads that aren’t based on other websites you’ve visited.’
‘Many websites will still collect and use your browsing data– for example, to improve security, to provide content, services, ads, and recommendations on their websites, and to generate reporting statistics.’
What this means is that not all websites necessarily have to honor ‘Do Not Track’ requests.
Contacting your local data privacy alliance
Google, Facebook and Twitter are just a few of the major corporations that are part of a number of privacy alliances that have agreed to honor requests to stop tracking.
These are the Digital Advertising Alliance in the US, the Digital Advertising Alliance of Canada and the European Interactive Digital Advertising Alliance.
The websites of each of these organizations contain instructions on how to add your details to their ‘do not track’ schemes.
Change your tacking settings in Facebook
Facebook has given users of its social network the option to opt out of ad tracking via the site.
First, log in to Facebook, go to Settings, then click on ‘Ads’ in the menu on the left-hand side of the screen.
Under Ad Settings, click on the button that says ‘Ads on apps and websites off of the Facebook Companies.’
Then scroll down to the bottom and select ‘No.’
Facebook says that if you select that option, it means that you’ll still see ads, but ‘they won’t be as relevant to you.’
Additionally, you may still see ads related to your age, gender or location.
