Every major platform now has a privacy dashboard. They are not hidden anymore, but they are also not the first thing you see, and the defaults still tend to favour data collection. This is a focused walk-through of the handful of settings on Google, Apple, and Facebook that have the biggest impact on what those companies know about you. None of these changes break anything. All of them take under fifteen minutes. The result is a calmer, less surveilled experience that you barely notice in daily use.
Google sits at the centre of more of your data than any other consumer company. The good news is that almost everything is controllable from a single dashboard once you know where to look.
Go to myaccount.google.com and sign in. The relevant sections are Data & Privacy and Security.
Turn Off Ad Personalization
Under Data & Privacy, find “My Ad Centre” or “Personalized ads.” Turn it off. You will still see ads, but they will not be targeted based on the profile Google has built from your activity. This single switch removes the most visible side effect of years of tracking.
Pause Activity Tracking
Under Data & Privacy, “Web & App Activity,” “Location History,” and “YouTube History” are the three big ones. Pause whichever you do not need. Web & App Activity is the most invasive of the three, because it logs your searches, voice commands, and many actions inside Google apps. Pausing it removes years of accumulated detail from future logs. You can also set auto-delete to 3 months for the activity you do want kept.
Review Connected Apps
Under Security, “Your connections to third-party apps and services” lists every app and website that has been granted access to your Google account. Some of these are forgotten signups from years ago. Revoke anything you no longer recognise or use. This cleanup directly reduces your exposure to a breach of any one of those third parties.
Two-Factor and Passkeys
Still in Security, turn on two-factor authentication if it is not already on. Add a passkey to the account if your devices support it. Your Google account is the recovery channel for many other services, so it is worth treating as high-value.
Sign Out of Inactive Sessions
Under Security, “Your devices” lists every device that is signed into your Google account. Remove anything you no longer use. Old phones, old browsers, old tablets you sold to a friend, all of them stay signed in until you explicitly sign them out.
Apple
Apple’s privacy posture is stronger out of the box than most of its competitors, but a few settings are worth turning on explicitly. Open Settings on iPhone or System Settings on macOS.
Mail Privacy Protection
Under Mail, Privacy Protection, turn on “Protect Mail Activity.” This hides your IP address from senders and loads remote content through an Apple proxy so tracking pixels cannot tie an open to your location. If you read mail in the built-in Mail app, this single switch defeats most email tracking.
App Tracking Transparency
Under Privacy & Security, “Tracking,” make sure “Allow Apps to Request to Track” is off, or at least review which apps you have allowed. With this off, apps cannot ask for permission to track you across other apps and websites at all, which is the strongest version of the setting.
Limit Ad Tracking on Apple Services
Under Privacy & Security, “Apple Advertising,” turn off “Personalized Ads.” Same idea as Google. Apple still serves ads in the App Store and Apple News, but they will not be tailored to a built-up profile.
Location Services
Under Privacy & Security, “Location Services,” review every app on the list. The right setting for most apps is “While Using the App” or “Ask Next Time.” Only a small number of apps need “Always,” and giving “Always” to a third-party app is essentially asking it to follow you around the world. Be particular here.
Hide My Email
If you have iCloud+, “Hide My Email” generates permanent aliases that forward to your real address. Use these whenever a site asks for an email and you are not sure how much you trust them. It is the simplest alias service for anyone already inside the Apple ecosystem.
Advanced Data Protection
Under your name, iCloud, Advanced Data Protection. Turn it on. This enables end-to-end encryption for almost everything in iCloud, including iCloud Drive, Photos, Notes, and device backups. You become responsible for your own recovery key, which Apple cannot help you reset, so write the key down and store it somewhere safe before you finish setup. The privacy gain is significant.
Facebook collects from inside the app, from its tracking pixels on the wider web, and from data partnerships. The settings panel cannot stop all of it, but you can shut down most of the explicit pipelines.
Open Facebook, then Settings & Privacy, Settings.
Off-Facebook Activity
Under “Your Facebook information,” find “Off-Facebook activity.” This is the running log of websites and apps that have reported your activity back to Facebook through tracking pixels. Clear the history, and then turn on “Disconnect future activity from your account.” Future tracking attempts will not be linked to your profile.
Ad Preferences
Under “Ads,” look for “Ad settings” or “Ad preferences.” Turn off “Ads based on data from partners” and “Ads based on your activity on Facebook Company Products that you see elsewhere.” Also review the categories Facebook thinks describe you, and remove the ones that bother you.
Facial Recognition and Photo Suggestions
If your region still allows it, find face recognition under Settings and turn it off. You do not need Facebook running a model of your face to tag you in friends’ photos.
Active Sessions
Under Security and Login, “Where you are logged in,” sign out of any device you do not currently use. Old laptops, public computers from years ago, devices you sold.
Apps and Websites
Under Settings, “Apps and websites” lists every third party that has been connected to your Facebook login. Disconnect anything you no longer use. Every connected app is one more channel for data to flow out of your account.
Profile Visibility
Under Privacy, set “Who can look you up using the email address you provided” and the same for phone number to “Friends” or “Only me.” This stops people from finding your profile through contact details, which closes one of the most common doxxing routes.
The Cross-Platform Habit
The settings above are platform-specific, but they all reinforce the same habit: actively limit what each service can collect, store, and share. Two further habits make the overall package much stronger.
The first is to use a temporary email for the dozens of small sign-ups that do not deserve a long-term relationship with you. Every site you skip is one less profile out in the world.
The second is to revisit these dashboards every six months. Defaults change. New features quietly opt you in. New connected apps appear. Half an hour twice a year is enough to keep the configuration where you set it.
What Changes After You Do This
You will not notice anything immediately. The apps still work, the searches still return results, the photos still upload, the social feeds still scroll. What changes is what happens behind the scenes. The size of the profile each platform maintains stops growing. The cross-app advertising network has less to work with. The risk of any single breach exposing a long history of your behaviour shrinks. And a year from now, when something in the news reminds you that you should “do something about privacy,” you can open a dashboard, see that your settings are still where you put them, and close the tab without anxiety.
