device's Facebook app, then Nearby Friends, then tap the gear icon. From that list, tap Location Settings, then switch the location history feature to off.

3. Stop Facebook from tracking your browsing habits
Earlier this month, Facebook announced it will soon use app and website data from your online browsing habits to provide you with more targeted ads. This means that if you perform a Google search for a particular restaurant, you may see ads for that restaurant on Facebook.
While Facebook isn't the only company to track your browsing habits for ad targeting -- Google does it, too -- you can opt out. On your desktop, visit the Digital Advertising Alliance. This website will scan for participating companies that have enabled customized ads for your browser. You can browse your results to learn more about their advertising and privacy practices, and opt out of this advertising for all or select ones.
To opt out on your mobile device, use the controls that iOS and Android provide, Facebook advises. This includes enabling private browsing, blocking cookies, and opting in to do-not-track.
4. Opt out of appearing in search engine results
Facebook automatically allows search engines to index your profile. This means that when friends, family, and employers Google your name, for example, search results may list a link to your page.
To prevent your profile from appearing in search engine results, visit your account settings page and click the privacy tab on the left. Click Edit next to the very last option, "Do you want other search engines to link to your timeline?" and uncheck the box. It may take some time for search engines to stop showing the link to your profile in its search results.
