Hey guys..
Now a days i market there is rumour that zuke is selling our private data to the third paries.. so be aware...
However, if you don't want Facebook to sell your personal information and browsing history to third-party companies, there's an easy way to opt out.
On any web browser, visit the Digital Advertising Alliance opt-out, and in the middle of the page, click on "Companies customizing ads for your browser." Select the boxes next to the names of companies you no longer wish to receive ads from, and then scroll down and click to submit your choices.
Mobile users will need to additionally opt out of advertising through special control settings embedded in iOS and Android. On iOS, visit the "Settings" app and open up the "Privacy" tab, click on "Advertising" and enable "Limit Ad Tracking." On Android, Facebook may add this setting as a user preference within the "Application Manager" found in "Settings," but you can also set up and manage a Virtual Private Network (VPN) on the device that should automatically disallow any browser tracking.
