All those years of browsing the News Feed and sharing selfies on Facebook have taught the company quite a lot about you.
In the Facebook settings for your account — right below the link to deactivate it — there’s an option to download a copy of all your Facebook data. The file can be a creepy wake-up call: All those years of browsing the News Feed, and sharing selfies, engagements and birthday wishes on Facebook have taught the company quite a lot about you. You, the user, are part of the reason that Facebook has become so good at targeting ads. You’re giving them everything they need to do it.
Log into your account and go to the settings page. Click on the link to download your archive, and follow the prompts.
Once you request it, Facebook will send two emails: The first acknowledges that a request was made, and the other gives you a link to go get the file when it’s ready. The size of your file — and therefore the time it takes for Facebook to create it — will vary.
