Controlling Your Data

Knowing that companies collect your data is one thing. Having practical power to limit, manage, and control that collection is another. The good news is that you have more levers than most people realize. Privacy is not all-or-nothing — every step toward control is meaningful, and small changes in digital habits compound over time into a significantly smaller data footprint.

Privacy Settings: The First Line of Control

Most apps and platforms offer privacy settings — controls that let you adjust what data is collected and how it is used. These settings are almost always buried, default to maximum data collection, and use confusing language. The defaults exist that way intentionally: the less data users restrict, the more the platform collects. Changing your privacy settings is the first and most accessible line of control. For social media, this typically includes: who can see your posts, whether the platform can use your activity for ad targeting, whether your data is shared with third-party partners, and whether location services are enabled. For your phone's operating system, settings typically let you control which apps can access your location, microphone, camera, contacts, and photos — and whether that access happens always, only when the app is open, or never.

Tracking and Cookies

Cookies are small files that websites store on your browser to remember information about you. Some cookies are essential — they keep you logged in across pages. Others are tracking cookies designed to follow you across the internet and build a behavioral profile. Most browsers now offer controls for blocking third-party tracking cookies — the kind used for surveillance across sites you did not intentionally visit. Browser extensions like ad blockers and tracker blockers can further reduce the amount of tracking that occurs as you browse. Private or incognito mode removes cookies and browsing history from your device when you close the window, though it does not prevent your internet service provider or the websites themselves from seeing your activity. App tracking on mobile devices is controlled through your phone's settings. Both major mobile operating systems now offer the ability to prevent apps from tracking you across other apps and websites — a significant privacy improvement that can be activated with a few taps.

Data Minimization: Giving Less

Data minimization is the practice of providing only the minimum information required to use a service and avoiding sharing data that is not strictly necessary. In practice, this means several things. Use throwaway email addresses for services you do not trust deeply. Many email providers let you create aliases that forward to your real address without exposing it. Use unique usernames rather than your real name on platforms that do not require identity verification. Avoid linking accounts — when a site says 'continue with Google' or 'sign in with Facebook,' choosing that option allows the third-party platform to learn about your activity on that site. Creating a separate account keeps those data trails from merging. When a form asks for information, ask yourself whether the field is required or optional. Optional fields are data you do not have to give, and most people fill them in out of habit.
