Online Privacy Explained: Tracking, Data Collection and How to Protect Yourself

Online privacy is the ability to understand and influence what information websites, apps, advertisers, platforms, data brokers and other digital services collect about you, how that information is combined, how long it is stored and who receives it.

That sounds straightforward. Modern data collection is not.

A single website visit can potentially reveal your IP address, browser, device characteristics, approximate location, language and actions on the page. Apps may collect location or device information. Advertising technologies can link activity across websites and services. If you sign into an account, years of searches, purchases, videos, clicks and other activity may become associated with one persistent identity.

The result is that online privacy is no longer simply about hiding your browsing history.

It is about the enormous amount of information created whenever people use modern digital services.

The Federal Trade Commission’s recent enforcement work shows how valuable this information can become. In 2026, the FTC moved to prohibit data broker Kochava and a subsidiary from selling or sharing sensitive location information without affirmative consent, resolving allegations involving data linked to hundreds of millions of mobile devices that could reveal people’s movements and visits to sensitive locations.

At the same time, the UK’s Information Commissioner’s Office finalized new guidance in April 2026 covering not only cookies but also tracking pixels, device fingerprinting and similar technologies.

The central lesson is simple:

You do not need to have “something to hide” for online privacy to matter.

Privacy determines how much power other organizations have to observe, classify, predict and influence your digital life.

For the wider security context around accounts, malware, phishing, networks and data protection, see The News Ink’s Cybersecurity Explained guide.

Online Privacy at a Glance

Tracking method	What it can reveal or connect	Main protection
Cookies	Visits, preferences and identifiers	Browser privacy controls
Tracking pixels	Page views, email opens and interactions	Tracker blocking
Fingerprinting	Browser/device characteristics	Anti-fingerprinting protection
Advertising IDs	Activity across mobile apps	Reset/restrict ad tracking
Location data	Where a device has been	Restrict app permissions
Account activity	Searches, views and purchases	Activity/privacy settings
Social tracking	Visits and interactions across sites	Limit cross-site tracking
Data brokers	Combined personal profiles	Opt-outs and privacy rights
Public records	Identity, property and other information	Limit unnecessary disclosure
Data breaches	Passwords and personal information	Unique passwords and MFA

No single setting eliminates every form of tracking.

Online privacy is best approached as reducing unnecessary exposure, not achieving magical invisibility.

Online Privacy, Cybersecurity and Anonymity Are Different

These terms are frequently mixed together.

Online Privacy

Privacy concerns how information about you is collected, used and shared.

Cybersecurity

Cybersecurity protects information and systems from unauthorized access, theft, manipulation or destruction.

Anonymity

Anonymity means preventing an activity from being linked to your real identity.

Confidentiality

Confidentiality means information is accessible only to authorized parties.

You can have good cybersecurity and weak privacy.

A company might securely store extremely detailed information about everything you do. Attackers cannot steal it, but the company can still build an enormous profile about you.

Likewise, privacy without security is fragile.

If a service promises not to share personal information but fails to protect its database, a breach can expose that information anyway.

Good digital protection requires both.

What Personal Data Do Websites and Apps Collect?

Personal data is much broader than your name and email address.

Depending on the service, information can include:

• IP address;
• device type;
• browser;
• language;
• operating system;
• search history;
• videos watched;
• products viewed;
• purchases;
• location;
• advertising identifiers;
• contacts;
• app usage;
• clicks;
• scrolling behavior;
• account activity;
• and information inferred from those activities.

A service does not always need your legal name to create a useful profile.

A persistent identifier can be enough to recognize the same browser or device across repeated interactions.

That profile can later become associated with your identity when you log in, make a purchase or provide contact information.

Cookies Explained

Cookies are small pieces of data websites store through a browser.

Cookies themselves are not automatically bad.

They perform useful functions.

A cookie may remember that:

• you signed in;
• an item is in your shopping cart;
• you selected English;
• or you already dismissed a notification.

These are often called first-party cookies because they are associated with the site you are intentionally visiting.

Tracking becomes more complicated when identifiers are used across different websites.

First-Party Cookies

Used mainly by the service you are visiting.

Third-Party Cookies

Historically used by advertising, analytics and other third parties that appear across many websites.

If the same advertising service appears on hundreds of sites, an identifier can potentially help connect visits across those sites.

This is one reason browsers, regulators and privacy laws have increasingly focused on cross-site tracking.

But eliminating one type of cookie does not eliminate online tracking.

Other technologies exist.

Tracking Pixels Can Be Almost Invisible

A tracking pixel can be a tiny or invisible resource loaded when someone opens a webpage or email.

Loading that resource creates a request to a server.

Depending on the implementation, the server may receive information such as:

• IP address;
• time of access;
• browser details;
• page or message identifier;
• and other associated data.

Pixels can be used for legitimate analytics.

They can also contribute to advertising and behavioral tracking.

The UK’s current privacy guidance specifically treats tracking pixels alongside cookies, fingerprinting and similar storage or access technologies.

That matters because telling users to “delete cookies” is no longer a complete online privacy strategy.

Browser Fingerprinting Can Track Without Traditional Cookies

Fingerprinting attempts to recognize a browser by combining characteristics exposed by the device and software.

Possible signals include:

• browser version;
• operating system;
• screen size;
• language;
• timezone;
• fonts;
• graphics capabilities;
• hardware characteristics;
• and browser settings.

Mozilla’s MDN documentation explains that combining enough distinguishing characteristics can create a browser fingerprint that helps identify users across the web.

The Electronic Frontier Foundation’s Cover Your Tracks research demonstrates why this is difficult to solve simply by clearing browser data: fingerprinting can rely on characteristics that are harder to erase than cookies.

Modern browsers increasingly include protections intended to reduce this type of identification.

Still, fingerprinting demonstrates a broader rule:

online tracking does not depend on one technology.

When one method becomes harder, advertising and analytics systems may develop alternatives.

Mobile Apps Create Another Privacy Layer

Phones contain far more than browsing history.

Depending on permissions, an app may potentially interact with:

• location;
• camera;
• microphone;
• photos;
• contacts;
• Bluetooth;
• nearby devices;
• health information;
• and other sensitive resources.

That makes app permissions one of the most important online privacy controls.

Before granting permission, ask whether the feature logically needs that information.

A map application has an obvious reason to request location.

A simple calculator usually does not.

Apple’s App Tracking Transparency system requires apps to request permission before tracking activity across other companies’ apps and websites for advertising, measurement or sharing with data brokers.

Apple also provides an App Privacy Report that can show how applications use permissions and communicate with network domains.

Other mobile platforms provide their own permission and privacy controls.

The exact menus change over time.

The principle does not:

give applications only the access they actually need.

Location Data Is Particularly Sensitive

Location information can reveal much more than coordinates.

Repeated location data may reveal patterns involving:

• home;
• workplace;
• schools;
• hospitals;
• religious institutions;
• political events;
• travel;
• relationships;
• and daily routines.

That is why data-broker location practices have received significant regulatory attention.

The FTC’s 2026 Kochava settlement involved allegations that location information from hundreds of millions of devices could be used to trace movements. The proposed restrictions require affirmative consent for sensitive location-data uses covered by the order.

Earlier FTC cases involving X-Mode, Mobilewalla and Gravy Analytics also focused on sensitive location information connected to places such as medical facilities, religious locations and domestic-abuse shelters.

For users, this creates a practical rule:

do not leave precise location permission permanently enabled for apps that only need it occasionally.

Use options such as “while using the app” or approximate location where they provide enough functionality.

What Are Data Brokers?

Data brokers collect, organize, analyze or sell information about people.

Information can come from many sources, potentially including:

• commercial transactions;
• public records;
• apps;
• advertising ecosystems;
• online behavior;
• location information;
• and information obtained from other businesses.

A single piece of information may appear harmless.

The privacy risk increases when multiple sources are combined.

An organization may not know only that a device visited a particular website.

It may potentially combine attributes into a much richer profile.

The FTC’s enforcement actions against location-data companies demonstrate why data-broker practices have become a significant consumer privacy issue.

In February 2026, the FTC also reminded data brokers of obligations under federal law restricting the provision of certain personally identifiable sensitive data about Americans to foreign adversaries.

Data has economic and strategic value.

That is why protecting privacy increasingly overlaps with national security.

Personalized Advertising Depends on Data

Personalized advertising attempts to show different people different advertisements according to information associated with them.

That information can include:

• searches;
• viewed content;
• interactions;
• demographic information;
• general location;
• interests;
• and account activity.

Google, for example, says My Ad Center allows users to control whether information including account activity, YouTube history and areas where Google services have been used contributes to ad personalization.

Turning personalized advertising off does not make advertisements disappear.

It changes how some ads are selected.

Google notes that non-personalized advertising can still rely on contextual factors such as the website topic, active search or current general location.

This distinction is useful.

Privacy controls often reduce particular forms of data use rather than stopping all data collection everywhere.

Data Collection Can Influence More Than Advertising

Advertising is only one potential use of behavioral data.

Consumer information can influence:

• recommendations;
• fraud detection;
• credit or risk systems;
• personalization;
• pricing;
• product development;
• identity verification;
• and automated decisions.

The FTC has investigated what it calls surveillance pricing, where companies may use information about people’s characteristics and behavior when determining individualized prices or offers. Its 2025 study examined how intermediary companies use historical and real-time consumer information for pricing technologies.

The FTC emphasized that its initial study included hypothetical examples and areas needing further research, so surveillance pricing should not be described as if every online retailer secretly charges each person a different price.

But the investigation demonstrates a broader privacy issue:

Data collected for one digital interaction can become valuable for decisions far beyond that original interaction.

Private or Incognito Browsing Does Not Make You Anonymous

This is one of the most common online privacy misunderstandings.

Private browsing is useful.

It generally reduces what the browser saves locally after the session.

That can include:

• browsing history;
• cookies;
• form information;
• and temporary site data.

It is useful when several people share a device.

It does not make you invisible on the internet.

Mozilla explicitly explains that Private Browsing does not hide activity from websites, an internet service provider or an employer, nor does it automatically mask your IP address.

Private browsing is mainly about limiting traces on your own device and, depending on the browser, applying additional tracking protection.

It is not complete anonymity.

Does a VPN Protect Online Privacy?

A virtual private network encrypts traffic between your device and the VPN provider and usually causes websites to see the VPN server’s IP address rather than your normal public IP address.

That can be useful.

But a VPN does not solve every online privacy problem.

A VPN does not automatically prevent:

• cookies;
• fingerprinting;
• tracking while signed into an account;
• social-media profiling;
• malicious websites;
• data collection performed directly by apps;
• or information you voluntarily provide.

It also shifts some trust.

Instead of your internet provider seeing certain network information, you are trusting the VPN provider to handle your traffic appropriately.

Choose VPN services carefully.

And remember that HTTPS already encrypts the contents of most ordinary modern web connections. The FTC’s current public Wi-Fi guidance notes that widespread HTTPS has made public Wi-Fi safer than it was during the early web, although users should still protect accounts and devices.

For a deeper explanation, see The News Ink’s public Wi-Fi safety guide.

12 Practical Ways to Improve Online Privacy

Absolute privacy is difficult.

Meaningful privacy improvement is not.

1. Review Browser Privacy Settings

Enable built-in tracking protection where appropriate.

Consider restricting third-party tracking and unnecessary site permissions.

2. Review Mobile App Permissions

Check:

• location;
• camera;
• microphone;
• contacts;
• photos;
• Bluetooth;
• and background access.

Remove permissions that no longer make sense.

3. Limit Cross-App Tracking

Use mobile privacy controls such as Apple’s App Tracking Transparency where available.

4. Review Advertising Preferences

Platforms including Google provide controls over personalized advertising and the activity used for ad personalization.

5. Reduce Unnecessary Location Access

Few applications require precise location all the time.

Prefer limited or approximate access where suitable.

6. Delete Accounts You No Longer Need

Every abandoned account can continue holding personal information.

Old accounts also create security risks if they use weak or reused passwords.

7. Use Unique Passwords

Privacy becomes irrelevant when somebody takes over your accounts.

Use unique credentials for important services.

The News Ink’s password manager guide explains why password reuse is dangerous.

8. Enable MFA or Passkeys

Protect email, cloud storage, social media and financial accounts.

The News Ink’s MFA and account-security guide covers stronger authentication methods.

9. Be Selective About Social-Media Information

Public posts can reveal:

• birthday;
• workplace;
• family;
• travel;
• location;
• routines;
• and relationships.

This information can be useful for profiling and social engineering.

10. Keep Devices Updated

Privacy requires security.

Malware can bypass browser settings entirely by stealing information directly from the device.

11. Review Active Sessions and Connected Apps

Periodically check which devices and third-party applications have access to important accounts.

Remove access you no longer need.

12. Use Your Legal Privacy Rights Where Available

Privacy laws increasingly provide rights to access, correct, delete or object to certain processing of personal information.

The exact rights depend on jurisdiction.

GDPR Gives Europeans Significant Data Rights

The European Union’s General Data Protection Regulation provides several important rights concerning personal information.

The European Commission lists rights including:

• being informed;
• access;
• rectification;
• erasure;
• restriction of processing;
• data portability;
• objection;
• and protections concerning automated decision-making and profiling.

The GDPR also relies on principles including purpose limitation and data minimization: organizations should have legitimate purposes for processing information and should not collect more than necessary for those purposes.

These principles have influenced privacy frameworks far beyond Europe.

Privacy Regulation Is Expanding Beyond Cookies

Modern privacy regulation increasingly recognizes that tracking technologies extend beyond traditional browser cookies.

The UK’s ICO finalized its Storage and Access Technologies guidance in April 2026.

It explicitly covers:

• cookies;
• tracking pixels;
• device fingerprinting;
• and related technologies.

The ICO said its compliance work had resulted in 99% of the UK’s top 1,000 websites meeting its cookie-banner compliance standards by April 2026.

This is a useful indication of how online privacy regulation is evolving.

Regulators increasingly focus on what a tracking technology does, not merely whether it is technically called a cookie.

Companies Need Privacy Risk Management Too

Consumers cannot carry the entire responsibility for online privacy.

Organizations collecting personal information have a role as well.

The NIST Privacy Framework is designed to help organizations identify and manage privacy risks created by data processing.

NIST describes it as a voluntary framework intended to support innovation while improving protection for individuals.

As of August 2026, NIST Privacy Framework 1.1 remains in development: the initial public draft was released in 2025 and NIST’s current project page says the final Version 1.1 is still “coming soon.”

That detail matters because draft frameworks should not be described as finalized standards.

Organizations should nevertheless apply enduring privacy principles:

know what you collect, minimize unnecessary data, protect it, explain its use and delete it when it is no longer needed.

Data Breaches Turn Privacy Problems Into Security Problems

A company may collect information for a legitimate purpose.

But every stored data point creates potential breach exposure.

If attackers compromise the organization, stolen information can include:

• names;
• addresses;
• passwords;
• health information;
• financial data;
• identification documents;
• location history;
• or private communications.

This is why data minimization has a security benefit.

Information never collected cannot later be stolen from that organization.

If personal data has already been exposed, see The News Ink’s data breach response guide.

A Practical Online Privacy Checklist

Action	Privacy benefit
Block unnecessary cross-site tracking	Reduces behavioral profiling
Review app permissions	Limits access to sensitive phone data
Restrict location access	Reduces movement tracking
Review ad personalization	Reduces some behavioral advertising uses
Delete unused accounts	Reduces stored personal information
Use unique passwords	Limits account compromise
Enable MFA/passkeys	Protects private account information
Remove old connected apps	Reduces unnecessary third-party access
Keep devices updated	Reduces malware exposure
Review account activity	Helps identify suspicious access
Limit public social data	Reduces profiling and social engineering
Exercise privacy rights	Provides access/deletion options where applicable

You do not need to perform every privacy action every day.

Reviewing important settings every few months can significantly reduce unnecessary exposure.

Frequently Asked Questions

What is online privacy?

Online privacy refers to how information about your identity, behavior, devices, location and activities is collected, processed, stored and shared when you use digital services.

Can websites track me without cookies?

Yes. Tracking can also involve pixels, account identifiers, browser fingerprinting, IP information and other technologies.

Does incognito mode stop tracking?

No. Private or incognito browsing mainly reduces information saved locally by your browser. Websites, internet providers and other parties may still observe activity, depending on the circumstances.

Does a VPN make me anonymous?

No. A VPN can encrypt traffic between your device and VPN service and mask your normal public IP address from destination sites, but it does not stop account-based tracking, cookies, fingerprinting or information you voluntarily provide.

What is browser fingerprinting?

Browser fingerprinting combines characteristics such as browser version, operating system, screen details, language, timezone and other features to distinguish one browser from others.

Why is location data sensitive?

Location history can reveal visits to homes, workplaces, medical facilities, religious institutions and other sensitive places. Recent FTC enforcement has specifically addressed the sale and sharing of sensitive location information.

Are cookies dangerous?

Not inherently. Cookies are essential for functions such as keeping users signed in or remembering preferences. Privacy concerns arise mainly when persistent identifiers are used for unnecessary profiling or cross-site tracking.

Can I completely stop online tracking?

Completely eliminating every form of tracking while using mainstream internet services is difficult. A more practical goal is minimizing unnecessary collection, reducing persistent identifiers and controlling which services receive sensitive information.

Is online privacy the same as cybersecurity?

No. Privacy concerns how information is collected and used. Cybersecurity protects data and systems from unauthorized access or attack. Strong digital protection requires both.

Conclusion

Online privacy has become more complicated because digital tracking no longer depends on one cookie stored in one browser.

Websites, mobile apps, advertising systems and data brokers can interact with information from many sources.

Cookies can recognize returning browsers.

Pixels can record interactions.

Browser fingerprinting can use device characteristics.

Apps may receive location or other sensitive permissions.

Advertising systems can build behavioral profiles.

Data brokers can combine information from multiple sources.

And account activity can connect years of digital behavior to one persistent identity.

That does not mean users are powerless.

Online privacy can be improved significantly through a series of practical choices.

Limit unnecessary app permissions.

Review browser tracking protection.

Restrict location access.

Reduce personalized advertising where desired.

Delete unused accounts.

Use unique passwords.

Protect important accounts with MFA or passkeys.

Review connected applications.

Keep devices updated.

And use legal access, objection or deletion rights where they are available.

It is equally important to understand what privacy tools cannot do.

Incognito mode does not make you anonymous.

A VPN does not prevent websites from recognizing an account you deliberately sign into.

Deleting cookies does not automatically defeat browser fingerprinting.

Strong passwords do not control what a legitimate service chooses to collect.

Real online privacy comes from layers.

It combines better technology, stronger cybersecurity, sensible personal choices, transparent business practices and effective regulation.

The goal should not be the impossible promise of leaving no digital trace.

The goal is having meaningful control over how much information you reveal, who receives it and what they are allowed to do with it.
