What Tracking Looks Like Beyond Cookies

Most people think tracking means cookies, but that’s only part of the story. Understanding how to stop hackers tracking you across other methods matters just as much. Websites and apps can follow you through many other methods, and clearing your cookies won’t stop them. Understanding each mechanism matters because the countermeasure for one type often does nothing against another.

Tracking pixels and web beacons

A tracking pixel is a tiny, often invisible image (typically 1×1 pixel) embedded in a web page or email. When your browser or email client loads it, the server logs your IP address, device type, and the time you opened the message. Marketers use pixels to measure open rates and to link your email identity to your browsing behavior across sites.

Device fingerprinting

Fingerprinting collects dozens of details about your device, screen resolution, installed fonts, browser version, time zone, language, graphics card characteristics, and more, and combines them into a profile that can be surprisingly unique. Unlike cookies, fingerprints are stored server-side, so clearing cookies does not reset them. Common countermeasures include using browsers with built-in fingerprinting resistance (such as Firefox’s Enhanced Tracking Protection in Strict mode or Brave’s fingerprint randomization), disabling unnecessary plugins, and avoiding rare font or extension combinations that make you stand out.

IP-based tracking

Your IP address reveals your approximate location and internet provider, and it can be used to link sessions even without cookies. A VPN masks your IP by routing traffic through a server, which reduces IP-based tracking but does not stop fingerprinting or account-level tracking. Network-level tools like DNS filtering can also block known tracker domains before they load.

Mobile app SDKs and permissions

Apps often include third-party software development kits (SDKs) from analytics and advertising companies. These SDKs can collect device identifiers, usage patterns, and location data, and share them with the SDK provider. On both iOS and Android, review app permissions (location, camera, microphone, contacts, tracking) and limit them to what the app actually needs. On iOS, enable App Tracking Transparency prompts and deny tracking where possible; on Android, review Privacy > Permission manager to audit which apps have sensitive access.

Account-based and logged-in tracking

When you are signed in to a Google, Apple, Microsoft, or social media account, activity can be associated with your identity across services. Review activity controls in each account (for example, Google’s Web & App Activity and Location History, Apple’s Analytics & Improvements settings, and ad personalization controls) and pause what you don’t need. Account-level tracking is often the most persistent because it follows you across devices.

Why one setting is never enough

Each tracking method has a different countermeasure: cookie cleanup for cookies, tracker blocking for pixels and scripts, fingerprint resistance for fingerprinting, VPNs for IP exposure, permission audits for apps, and account controls for logged-in activity. A practical approach layers several of these rather than relying on any single fix.

Verify that tracking is reduced

After changing settings, confirm the effect:

• Check your browser’s privacy or tracker-blocking report (Firefox’s shield icon, Edge’s tracking prevention indicator, Brave’s Shields panel) to see blocked trackers per page.
• Review stored cookies and site data for a frequently visited site via the lock icon in the address bar.
• On mobile, open the privacy dashboard (iOS: Settings > Privacy & Security > App Privacy Report; Android: Settings > Privacy > Privacy dashboard) to see which apps accessed location, camera, and microphone recently.

A dedicated privacy tool can bundle several of these layers. BullZIGA’s PC Privacy Shield is designed to help reduce unnecessary digital exposure.

How to Remove Tracking Cookies in Your Browser

Cookies are still worth clearing. They store login sessions and ad profiles, so removing them resets much of what sites know about you. But the exact menu path differs by browser and device, and generic advice often leaves readers stuck. Below are current, specific steps for the most common browsers on desktop and mobile.

Desktop browsers

Google Chrome (Windows, macOS, Linux)

1. Click the three-dot menu in the top-right corner and choose Settings.
2. Select Privacy and security in the left sidebar, then Third-party cookies.
3. To block cross-site tracking, choose Block third-party cookies. To clear existing cookies, go back to Privacy and security and click Delete browsing data.
4. Select Cookies and other site data (add Cached images and files for a deeper cleanup), pick a time range such as All time, and click Delete data.
5. Optional: under Privacy and security, open Site settings > Additional content settings > On-device site data to review which sites store data locally.

Mozilla Firefox (Windows, macOS, Linux)

1. Open the hamburger menu and choose Settings.
2. Click Privacy & Security.
3. Under Cookies and Site Data, click Clear Data and select Cookies and Site Data (and Cached Web Content if desired).
4. To block trackers going forward, set Enhanced Tracking Protection to Strict or Custom, and enable Cookies blocking for cross-site trackers.

Microsoft Edge (Windows, macOS)

1. Open the three-dot menu and choose Settings.
2. Select Privacy, search, and services.
3. Under Clear browsing data, click Choose what to clear, select Cookies and other site data, and click Clear now.
4. Under Tracking prevention, choose Balanced or Strict to limit cross-site tracking.

Safari (macOS)

1. Open Safari > Settings (or Preferences on older versions).
2. Click the Privacy tab.
3. Click Manage Website Data, then Remove All to clear cookies, or select specific sites and click Remove.
4. Enable Prevent cross-site tracking and consider Block all cookies (note: this can break some sign-ins).

Mobile browsers

Chrome on Android

1. Open Chrome, tap the three-dot menu, and choose Settings.
2. Tap Privacy and security > Delete browsing data.
3. Select Cookies and site data (and Cached images and files), choose a time range, and tap Delete data.

Chrome on iOS (iPhone/iPad)

1. Open Chrome, tap the three-dot menu, and choose Settings.
2. Tap Privacy and security > Delete browsing data.
3. Select Cookies, site data, choose a time range, and tap Delete browsing data.

Safari on iOS

1. Open Settings (the phone’s Settings app, not Safari’s), scroll to Safari, and tap it.
2. Tap Clear History and Website Data, then confirm.
3. To block cross-site tracking, enable Prevent Cross-Site Tracking in the same Safari settings screen.

Firefox on Android/iOS

Try for Free →

1. Open Firefox, tap the menu, and choose Settings.
2. Tap Delete browsing data (Android) or Data Management (iOS).
3. Select Cookies and confirm deletion.

Note: You will be logged out of most sites after clearing cookies. This is normal and a sign the cleanup worked. Some sites may also reset preferences like language or theme.

Verify that cookies were actually cleared

After clearing, confirm the change took effect:

• In Chrome, open Settings > Privacy and security > Third-party cookies and check that Block third-party cookies is selected.
• Visit a site you use often and open the browser’s site information panel (the lock icon in the address bar) to review stored cookies under Cookies and site data.
• Use the browser’s built-in privacy report (Firefox shows a shield icon with blocked trackers; Edge shows a similar tracker prevention indicator) to see how many trackers were blocked on the current page.

How to Turn Off Google Tracking in Your Account and Browser

Google collects activity data across its services. You can limit that collection in your account settings.

1. Sign in to your Google account and open the Data & Privacy section.
2. Review your activity controls, including Web & App Activity and Location History.
3. Turn off the controls you don’t want. Pause any that are not needed for features you use.
4. Review ad personalization settings and turn off personalized ads if you prefer.

Changes in your account only cover data Google collects through your account. Pair these steps with browser-level blocking for better coverage.

How to Stop Location Tracking on Your Phone

Location access is one of the most sensitive permissions on a phone. Apps often request it even when they don’t need it.

• On iPhone: Go to Settings, then Privacy & Security, then Location Services. Review each app and choose “Never” or “While Using” for apps that don’t need constant access.
• On Android: Go to Settings, then Location, then App location permissions. Set apps to “Allow only while using the app” or deny access.
• Turn off location history or significant locations features if your phone offers them.

How to Check If Your Device Has Spyware

Spyware can be hard to spot. Some signs suggest a problem, but none of them prove it on their own.

Watch for:

• Battery draining faster than usual
• Unexplained data usage spikes
• Apps you don’t remember installing

If you see these signs, take these steps:

1. Review installed apps and remove anything unfamiliar.
2. Check app permissions for camera, microphone, and location access.
3. Run a reputable security scan on your device.
4. Change passwords for important accounts from a separate, clean device.
5. Use a webcam blocker or cover the camera when it’s not in use.

Watch out: Removing an app may not remove everything it installed. Scan the device after cleanup to confirm.

Blocking Trackers With Browser Settings and Extensions

Browser settings and extensions add a second layer of protection on top of cookie cleanup.

• Turn on enhanced tracking protection or the equivalent setting in your browser.
• Block third-party cookies, which move data between sites.
• Consider a VPN to hide your IP address and browsing activity from networks.

For a broader approach, a dedicated privacy suite can bundle several of these tools.

Trade-off to know: Strong blocking can break some website features, such as logins, checkout pages, or embedded videos. If a site stops working, allow it temporarily instead of turning off all protection.

Setting Up a Monthly Privacy Check-Up

Privacy settings drift over time. Apps update, new permissions appear, and old sessions linger. A short monthly routine keeps you ahead of this.

Each month, work through this checklist:

Before committing to any protection product for this routine, read the refund policy to understand the terms.

• Clear cookies and site data in your browser
• Review app location and camera permissions on your phone
• Check your Google activity controls

Stop hackers tracking you by treating it as an ongoing habit, not a single fix. Combine browser cleanup, account settings, phone permissions, and a regular check-up.

Frequently Asked Questions

How do I tell if a website is tracking me?

Start with your browser’s privacy or site information panel, which usually lists the cookies and trackers loading on the page you are viewing. Browser extensions that display tracker lists can also show which third-party domains are active. Seeing many unfamiliar domains from advertising networks is a common sign of cross-site tracking. Checking these lists after you clear cookies and reload a page is a practical way to confirm that your settings are working.

Can a VPN stop hackers from tracking my location?

A VPN hides your IP address from the websites you visit and encrypts traffic between your device and the VPN server, which makes it harder for outsiders on public networks to see what you are doing. It does not stop apps on your phone from using GPS, and it does not block cookies or account-based tracking by sites you log into. Use a VPN alongside location permission settings, not as a replacement for them.

Is online tracking illegal?

Tracking by websites and advertisers is generally legal in the United States when disclosed in a privacy policy, though some state privacy laws give residents the right to opt out of certain data sales and targeted advertising. Tracking by an attacker who gains unauthorized access to your device or accounts is illegal. If you suspect unauthorized access, change your passwords, enable multi-factor authentication, and report it to the platform involved.

How do I remove tracking cookies from my browser?

In most browsers, open the settings menu, find the privacy or clear browsing data section, and select cookies and site data. Choose a time range, then confirm. Deleting cookies signs you out of most sites, so you will need to log back in. To limit future tracking, block third-party cookies in the same settings area, and consider enabling a setting that clears cookies each time you close the browser.
