#TechBytes: How to keep your data safe from Facebook

Facebook collects information on a humongous scale to create digital profiles for serving ads.

Obviously, the company uses the data you give willingly, like the photos you share or places you check-in.

But, beyond that, it mines your web activity (links clicked), your location from apps, and information from partner brands and services.

Now, that means a lot of personal data to sell!

First of all, you need to control what data Facebook uses to show ads to you.

For this, head over to Facebook settings > Ads > Ad preferences > Ad settings and opt out of seeing "Ads based on data from partners" - third-party websites.

Then, do the same for "Ads based on your activity on Facebook company products that you see elsewhere".

If last year's Cambridge Analytica scandal that compromised millions is a lesson, you should be very careful about third-party apps on Facebook.

The social network has since improved the options for controlling apps' access, which you can do by heading over to Settings > Apps & Websites and changing what connected apps can or cannot access.

You can also remove unwanted apps if needed.

Facebook can get information about your online activity from web trackers on third-party websites.

Now, this, CNET says, can be controlled with the help of external tools like the Safari browser or Facebook Container extension for Firefox.

Both can block the social network from using third-party cookies and browser fingerprinting for tracking web activity and maintaining a record of it.

Finally, you should cut off Facebook's access to your location by heading over to Settings > Location > Location access.

Here, you could either turn off Facebook's access to location services or keep the setting on and disable the 'Background Location' option to prevent Facebook from knowing your location when the app is not running.

You can even use VPN to mask your location.
