Trying to take control of your online privacy can feel like a full-time job. But if you break it up into small tasks and take on one project at a time it makes the process of protecting your privacy much easier. This month we’re going to do just that. For the month of October, we’ll update this post with new tips every weekday that show various ways you can opt yourself out of the ways tech giants surveil you.

Online privacy isn’t dead. But the tech giants make it a pain in the butt to achieve. With these incremental tweaks to the services we use, we can throw sand in the gears of the surveillance machine and opt out of the ways tech companies attempt to optimize us into advertisement and content viewing machines. We’re also pushing companies to make more privacy-protective defaults the norm, but until that happens, the onus is on all of us to dig into the settings.

All month long we’ll share tips, including some with the help from our friends at Consumer Reports’ Security Planner tool. Use the Table of Contents here to jump straight to any tip.

Tip 1: Establish Good Digital Hygiene

Before we can get into the privacy weeds, we need to first establish strong basics. Namely, two security fundamentals: using strong passwords (a password manager helps simplify this) and two-factor authentication for your online accounts. Together, they can significantly improve your online privacy by making it much harder for your data to fall into the hands of a stranger.

Using unique passwords for every web login means that if your account information ends up in a data breach, it won’t give bad actors an easy way to unlock your other accounts. Since it’s impossible for all of us to remember a unique password for every login we have, most people will want to use a password manager, which generates and stores those passwords for you.

Two-factor authentication is the second lock on those same accounts. In order to login to, say, Facebook for the first time on a particular computer, you’ll need to provide a password and a “second factor,” usually an always-changing numeric code generated in an app or sent to you on another device. This makes it much harder for someone else to get into your account because it’s less likely they’ll have both a password and the temporary code.

This can be a little overwhelming to get started if you’re new to online privacy! Aside from our guides on Surveillance Self-Defense, we recommend taking a look at Consumer Reports’ Security Planner for ways to help you get started setting up your first password manager and turning on two-factor authentication.

Tip 2: Learn What a Data Broker Knows About You

Hundreds of data brokers you’ve never heard of are harvesting and selling your personal information. This can include your address, online activity, financial transactions, relationships, and even your location history. Once sold, your data can be abused by scammers, advertisers, predatory companies, and even law enforcement agencies.

Data brokers build detailed profiles of our lives but try to keep their own practices hidden. Fortunately, several state privacy laws give you the right to see what information these companies have collected about you. You can exercise this right by submitting a data access request to a data broker. Even if you live in a state without privacy legislation, some data brokers will still respond to your request.

There are hundreds of known data brokers, but here are a few major ones to start with:

Data brokers have been caught ignoring privacy laws, so there’s a chance you won’t get a response. If you do, you’ll learn what information the data broker has collected about you and the categories of third parties they’ve sold it to. If the results motivate you to take more privacy action, encourage your friends and family to do the same. Don’t let data brokers keep their spying a secret.

You can also ask data brokers to delete your data, with or without an access request. We’ll get to that later this month and explain how to do this with people-search sites, a category of data brokers.

Tip 3: Disable Ad Tracking on iPhone and Android

Picture this: you’re doomscrolling and spot a t-shirt you love. Later, you mention it to a friend and suddenly see an ad for that exact shirt in another app. The natural question pops into your head: “Is my phone listening to me?” Take a sigh of relief because, no, your phone is not listening to you. But advertisers are using shady tactics to profile your interests. Here’s an easy way to fight back: disable the ad identifier on your phone to make it harder for advertisers and data brokers to track you.

Disable Ad Tracking on iOS and iPadOS:

  • Open Settings > Privacy & Security > Tracking, and turn off “Allow Apps to Request to Track.”
  • Open Settings > Privacy & Security > Apple Advertising, and disable “Personalized Ads” to also stop some of Apple’s internal tracking for apps like the App Store. 
  • If you use Safari, go to Settings > Apps > Safari > Advanced and disable “Privacy Preserving Ad Measurement.”

Disable Ad Tracking on Android:

  • Open Settings > Security & privacy > Privacy controls > Ads, and tap “Delete advertising ID.”
  • While you’re at it, run through Google’s “Privacy Checkup” to review what info other Google services—like YouTube or your location—may be sharing with advertisers and data brokers.

These quick settings changes can help keep bad actors from spying on you. For a deeper dive on securing your iPhone or Android device, be sure to check out our full Surveillance Self-Defense guides.
