Free Guide to Understanding Privacy Settings

What Privacy Settings Are and Why They Matter

Privacy settings are controls that let you decide who sees your information and what they can do with it. Think of them like locks on different rooms in your house—you choose which doors stay open, which stay partially open, and which stay completely closed. Every website, social media platform, email service, and app you use has privacy settings built in.

Your personal information is valuable. Companies use it to show you targeted advertisements, improve their services, and sometimes sell it to other businesses. Without privacy settings, strangers on the internet could see your photos, know where you live, learn about your family members, and track your online activity. Privacy settings give you control over this information.

Privacy breaches happen regularly. In 2023, data breaches exposed personal information of millions of people, including names, addresses, phone numbers, and financial details. While no privacy setting can completely prevent a company from being hacked, controlling who can see your information reduces your risk. If fewer people have access to your data, fewer people can misuse it.

Different platforms have different privacy needs. Your email account might need stronger protections than a public forum where you discuss gardening. Your bank's website requires different settings than a social media account. Understanding what information each service collects and where it goes is the first step to protecting yourself.

Practical Takeaway: Privacy settings exist on nearly every online platform. Before sharing information anywhere, pause and ask: "Who needs to see this, and who shouldn't?" This simple question will help you decide which privacy settings to use.

Understanding What Information Gets Collected

Every time you go online, you leave digital footprints. Websites and apps collect different types of information about you. Some of it is obvious—like your name and email address when you create an account. Other information is collected without you realizing it.

Basic information includes anything you type directly: your name, address, phone number, email, birth date, and passwords. When you fill out forms on websites, create accounts, or make purchases, you're providing basic information. You have the most control over this type of data because you choose whether to provide it.

Behavioral information tracks what you do online. This includes which websites you visit, how long you stay on each page, which links you click, what you search for, and what products you look at. Advertisers use this information to figure out what you're interested in. If you search for running shoes, you'll suddenly see running shoe advertisements everywhere.

Location information shows where you are physically. Your phone knows your location through GPS, cell towers, and WiFi networks. Apps request permission to use this data. A weather app needs your location to show local forecasts. A restaurant app might use location to show nearby restaurants. But some apps request location access for purposes that aren't clear.

Device information includes technical details about your computer or phone: what operating system it uses, what browser you use, what type of device it is, and unique identifying numbers. Websites use this to make sure they display correctly on your device. However, this information can also be used to fingerprint your device—creating a unique profile of you based on your technical setup.

Connection information shows who you interact with. Social media platforms know who your friends are, who you message, and whose content you view. Email services see who you email and can read the contents of your messages. Messaging apps track who you communicate with and when.

Practical Takeaway: Before using any new website or app, think about what information it needs to work. A weather app needs your location. A streaming service needs your payment information. But if an app asks for information it doesn't need to function, that's a red flag. Don't grant permissions you don't understand.

How to Find and Adjust Privacy Settings on Major Platforms

Every major platform stores privacy settings in slightly different locations, but they follow similar patterns. Learning where to find these settings on one platform makes it easier to find them on others. Most platforms hide privacy settings in account settings, preferences, or security sections.

On Facebook, privacy settings are found in the Settings menu (the downward arrow in the top right corner). Under "Privacy," you can control who sees your posts, who can contact you, and who can search for you by phone number or email. You can also review which apps have permission to access your information. The "Apps and Websites" section shows every third-party app connected to your account. Remove any apps you no longer use.

Google accounts control privacy across Gmail, Google Search, Google Maps, YouTube, and other services. Visit myaccount.google.com to find privacy and security settings. The "Data & Privacy" section shows what information Google has collected about you. You can review your activity across all Google services and delete information you don't want stored. Google's privacy settings also control whether your search history is saved and whether your location is tracked.

Microsoft accounts manage settings for Outlook email, OneDrive cloud storage, and Windows devices. Go to account.microsoft.com and select "Privacy" to see what information Microsoft collects. You can control whether Microsoft uses your data for targeted advertising. The "Your Info" section lets you review and delete personal information stored in your account.

Apple's privacy settings are in Settings on your device. Go to Privacy to see what apps have permission to access your camera, microphone, location, contacts, and photos. Each permission can be granted to individual apps. You can also enable "App Privacy Report" to see which apps access sensitive information and how often.

Instagram, TikTok, Twitter, and other social platforms have privacy settings in their account menus. Look for "Privacy and Safety" or similar options. You can usually choose between a public account (anyone can see your posts) or a private account (only approved followers can see your posts). You can also control who can message you and who can comment on your posts.

Email services like Gmail, Outlook, and Yahoo allow you to see which devices are signed into your account and remove devices remotely. This is important if you use email on your phone, computer, and tablet—you can log out of devices you no longer use. This prevents someone who gains access to an old device from reading your emails.

Practical Takeaway: Spend 15 minutes checking privacy settings on the three platforms you use most. Most platforms have a privacy checkup tool that walks you through important settings. Write down what you changed so you remember what actions you took.

Controlling Who Sees Your Information and What They Can Do With It

Privacy settings often offer choices about visibility. You can usually choose between public (everyone can see), friends only, specific people, or private (no one can see except you). The right choice depends on what kind of information you're sharing.

Public posts are visible to anyone on the internet—including people you don't know, search engines, and companies that collect data from social media. Use public posts for information you're comfortable with strangers knowing. News articles, public opinions, and information you'd be comfortable seeing on the front page of a newspaper are appropriate for public posts.

Friends-only posts are visible to people you've approved as friends. This is better for personal photos, family updates, and information you want to share with people you know. However, remember that your friends can screenshot or share your posts with others. Nothing posted online is truly private, even with restricted sharing.

Specific person settings let you share information with individual people. Some platforms let you create groups—like "close friends" or "family"—and share different content with each group. This works well if you want to share vacation photos with family but not with all your acquaintances.

Permission controls determine what others can do with your information. Some platforms let you control whether people can tag you in photos (mark you as the person in a picture), comment on your posts, or message you directly. Review these settings carefully. Being tagged in unwanted photos or receiving unwanted messages can impact your safety and privacy.

Third-party access is a critical privacy control. Many apps and websites request permission to connect to your social media, email, or other accounts. This access lets them read your information, post on your behalf, or gather data about you. Review which apps have these permissions and remove access to apps you no longer use or don't trust.

Data sharing with advertisers is common on free platforms. You can usually turn off behavioral tracking or choose not to see personalized ads. Some platforms offer "opt-out" options for targeted advertising, though advertising will continue—it just won't be as tailored to your interests.
