Frequently asked questions

What is Facebook used for?

Facebook is a social networking app for keeping in touch with friends and family, sharing posts, photos, and videos, and following pages or groups. It also includes features such as events, Marketplace, and video content. What you see can depend on your settings, the accounts you follow, and your location. Before downloading, consider whether you want these features and review the privacy controls available in the app.

Is Facebook free to download and use?

Facebook is generally free to download and use, although mobile data charges may apply when you are not connected to Wi-Fi. The app displays advertising, and some features or purchases offered through Facebook may have separate costs. Availability can vary by country and device. Check the app-store listing and any payment details carefully before confirming a purchase, and remember that using a free account does not mean your activity is never used to personalize content or ads.

What information does Facebook collect, and can I control my privacy?

Facebook may process information you provide, such as profile details, posts, and messages, as well as information about how you use its services and device or connection data. The exact practices can change, so read Facebook’s current privacy information before signing up. In the app, you can review settings for audience selection, profile visibility, location, notifications, and ad preferences. Take time to adjust them, since a post’s audience can depend on the option selected when you share it.

Can I use Facebook to buy and sell items safely?

Facebook Marketplace lets people browse local listings and contact sellers, but transactions are generally arranged between users, and protections may differ depending on the item, location, and payment method. Check a seller’s profile and listing carefully, ask questions, and avoid sending money through unfamiliar or irreversible methods. Be cautious of requests for verification codes, suspicious links, or deals that seem unusually attractive. Review Facebook’s current Marketplace guidance and meet in a safe public place when arranging an in-person exchange.

What should I know before downloading Facebook on my phone?

Before installing Facebook, check that your Android or iOS device meets the app’s current requirements and has enough storage. The app’s size, features, and permissions can vary by device and update, so consult the official app-store listing. Facebook may request access to features such as photos, camera, microphone, or location for specific functions; you can review or change permissions in your phone’s settings. Also consider that frequent browsing and video playback can use substantial data and battery.
