What is Privacy Guardian online privacy protection?

Available in System Mechanic Ultimate Defense (formerly Phoenix 360) as well as a standalone desktop app, Privacy Guardian is installed as a web browser extension to thwart malicious online entities from accessing your sensitive personal data, device info, and habits whenever you use the internet.

Privacy Guardian focuses on fingerprint-based tracking by studying the behaviors of known fingerprinting scripts and scrambling the data they rely upon to gain sensitive information about you. The tracking Privacy Guardian detects is independent of whether there are ads with tracking cookies on a site. Privacy Guardian users are alerted every time there is an attempt to track them online, regardless of whether an ad is visible.

Privacy Guardian also allows you to schedule automatic cookies- and cache-clearance on multiple web browsers from within the dashboard.

How do I access Privacy Guardian?

System Mechanic Ultimate Defense users can access the full version of the online privacy feature Privacy Guardian by clicking the Privacy Guardian eyeball icon at the top of the homescreen. The free version of Privacy Guardian is also available in System Mechanic.

Standalone users, double-click the Privacy Guardian desktop icon. You should also see access to the free versions of System Mechanic, ByePass password manager, and Malware Killer on-demand malware removal.

Why must I install the Privacy Guardian browser extension?

Many web browsers—including Chrome, Firefox and Opera—require the use of extensions (aka “add-ons”) for certain types of software to be compatible. Browser extensions add features to your web browser, in this case, the online privacy tool Privacy Guardian.

Because Privacy Guardian is a browser-based anti- tracking application that protects your online activities from spying eyes while you are using the internet, adding the extension to your browser is the only way Privacy Guardian will be able to protect your browsing from tracking attempts. (Microsoft’s Internet Explorer and Edge browsers do not require you to enable extensions.)

How do I install the Privacy Guardian browser extension?

These steps only apply to Privacy Guardian Standard standalone product and not Privacy Guardian which has been incorporated into the full System Mechanic Ultimate Defense suite of applications.

Before installing the Privacy Guardian browser extensions, first make sure that your web browsers are fully up-to-date. Second, the latest Windows updates should be fully applied.

Even if you typically use just one web browser, it is recommended that you enable online privacy protection for each of your browsers. If you have not already been prompted by Privacy Guardian and therefore done so, to enable privacy protection for your browsers:

  • From the Privacy Guardian Dashboard, click Browsers.
  • Here you will see a list of browsers available for privacy protection.
  • Choose a browser from the list, and click Enable.
  • Follow the onscreen steps as Privacy Guardian walks you through adding the browser extension for the browser.
  • Moving down the list of available browsers, click Enable and follow the onscreen instructions for each subsequent browser.

What is the difference between extensions and plug-ins?

Browser extensions (or add-ons) are not the same as browser plug-ins. Plug-ins allow websites to embed and render content such as Flash movies or Java applets. Generally speaking, plug-ins are far less secure than extensions because websites can load them and exploit any security holes or bugs within them. Websites are prevented from commandeering your extensions to perform actions. Simply stated, whereas extensions add browser features you can use, plug-ins add browser features websites you visit can use.

How do I clear my browsing data and cookies from within Privacy Guardian?


Clearing your browsing data:

  • Open the My Tracks tab.
  • Click Clear data next to the browser(s) you wish to clear.
  • When the clearance settings box opens, click the boxes next to the items you wish to clear. Items with a red square will be cleared. Reading the description for each item may help you decide. Among the items you may select are cookies.
  • Note that these boxes begin as unchecked each time you go to clear your browsing data, to help prevent you from accidentally clearing data you wish to keep.
  • When you are finished deciding which browsing data to clear (including cookies), click Clear selected data now.
  • Click the red X on the top right of the browser-clearance notification message to close it.

How do I turn off cookie clearance for specific websites?

Some cookies are useful, e.g., by keeping you logged in to trusted websites or retaining your shopping cart orders. To whitelist certain websites from your manual cookie clearance, follow these steps:

  • From the Privacy Guardian Dashboard, click My Tracks.
  • On the right side of the window, click the red Add or remove websites from whitelist button.
  • You may Choose from popular options if you are unsure which websites to whitelist.
  • Click within the box that says Enter website URL to the whitelist to enter a specific website you have in mind.
  • Review your whitelisted sites in the box below this entry field.
  • Click Remove to re-enable cookie clearance for any given website in this list.
  • When you are finished making changes, click Done.


How do I access Privacy Guardian settings?

The settings screen allows you to check for software updates, enable or disable tracking detection and adjust how Privacy Guardian notifies you.

  • From any tab within the Privacy Guardian panel, click the gear icon located in the red menu bar at the top.
  • Click the red X on the top right of the settings screen to close it and return to the main Privacy Guardian panel.
  • System Mechanic Ultimate Defense users can access additional settings from the System Mechanic Settings (gear icon) menu.
  • Scroll down to the Privacy Guardian settings tab, where you can enable tracking detection, as well as set Privacy Guardian to automatically launch at startup.

Why don't I see the Privacy Guardian Windows system tray icon?

If you have Privacy Guardian as part of System Mechanic Ultimate Defense, you can turn browser tracking detection (“filtering”) on and off within the System Shield system tray icon. To do this, you must first activate the System Shield tray icon by installing System Shield. System Shield is the real-time AV protection you purchased as a part of System Mechanic Ultimate Defense that does not automatically install along with it.

System Mechanic Ultimate Defense will prompt you to install System Shield after a system analysis detects that it is not yet installed; installation is then achieved with a single click.

Note that after installing System Shield, you do not need to enable System Shield real-time AV protection in order to adjust Privacy Guardian from within the System Shield tray icon.

After the tray icon appears, if you still have trouble seeing the Privacy Guardian: Enable/Disable Filtering option in the tray icon menu, try briefly enabling System Shield real-time protection, and disabling it later if desired.


If you are not interested in installing System Shield (e.g., you have your own AV that you are happy with) or the tray icon option for enabling/disabling Privacy Guardian, you can enable/disable Privacy Guardian from within the System Mechanic Settings menu:

  • From the System Mechanic dashboard, click the gear icon in the top red menu bar.
  • Scroll down to Privacy Guardian Settings.
  • Check/uncheck Enable tracking detection.

Note that you cannot uninstall Privacy Guardian separately from uninstalling System Mechanic Ultimate Defense.

I purchased System Mechanic Ultimate Defense, but already have Privacy Guardian as a standalone product. Do I need to do anything?

Standalone users who have purchased System Mechanic Ultimate Defense will be prompted during installation that the Privacy Guardian product is installed and to first uninstall it.  

To uninstall the Privacy Guardian standalone product:

  • On the bottom right of your computer screen, click on the up arrow to reveal your currently open apps.
  • Locate the Privacy Guardian red eyeball symbol (system tray icon) and right-click.
  • Select Quit Privacy Guardian.
  • Go to Windows Add or remove programs by typing it into the Windows Search bar.
  • Find Privacy Guardian among the list of applications and click to highlight it.
  • Select Uninstall from the top list of options.

To note, once System Mechanic Ultimate Defense is installed, the standalone version of Privacy Guardian can be re-installed but it is ill advised since running two versions of Privacy Guardian may cause conflicts between each programs settings.

How do I upgrade from the Free Standalone to the Full Standalone version of Privacy Guardian?

This question addresses only users who have purchased Privacy Guardian as a standalone product, and not as part of System Mechanic Ultimate Defense.

After you have completed purchase of the full version of Privacy Guardian in the online shopping cart, you must close Privacy Guardian and restart it. Your license should now have been upgraded to the full version.

To close out of Privacy Guardian, since the software runs in the background whenever you are using your computer, merely closing the Privacy Guardian dashboard isn’t sufficient—you must close the app from within the Windows system tray and restart it to activate the full version:

  • On the bottom right of your computer screen, click on the up arrow to reveal your currently open apps.
  • Locate the Privacy Guardian red eyeball icon and right-click.
  • Select Quit Privacy Guardian.
  • Re-launch Privacy Guardian to start enjoying the benefits of full online privacy protection.

Note that it may take up to one hour after purchase for your new license to activate the full version of Privacy Guardian. If after following the above steps you are still having trouble activating the full version, please contact Customer Support for help. Once you message the Support portal iolo Support agents will be in contact with you via email and phone.

Is Privacy Guardian collecting and studying my data in order to protect it?

No, Privacy Guardian is not collecting, tracking, storing, using, selling or even analyzing ANY of your online data. Privacy Guardian encrypts this data with a proprietary scrambling algorithm designed to confound today’s aggressive fingerprint-based tracking scripts. This prevents anyone from seeing it.

How is Privacy Guardian different from incognito mode in my web browser?

Privacy Guardian, which works perfectly well if you are browsing in incognito mode, thwarts tracking attempts that can get past incognito mode. Incognito mode prevents local storage of browsing data, so items like cookies, search history and autofill are not saved. But incognito mode does nothing to prevent the loading of tracking scripts used by data-mining entities to digitally fingerprint you. This, again, is the process of creating a detailed profile of you by collecting countless metrics from your web browser—a process unabated by incognito mode.

As a test, you can enable Privacy Guardian while browsing in incognito mode and still see the many tracking attempts detected by Privacy Guardian.

Won’t a Virtual Private Network (VPN) protect my privacy?

No, not entirely. Privacy Guardian is the perfect complement to a VPN, which can mask your location. A VPN offers some privacy protection by encrypting the internet connection between your computer and the VPN provider’s server, making your internet traffic appear as if it comes from the IP address of the VPN server, and it helps protect you from snooping by your internet service provider (ISP). But after the VPN server, the traffic flows outside of the VPN encryption, where most of the digital fingerprinting scripts are injected into the web pages you ultimately visit, so you can still be tracked even when your VPN is enabled.

Does Privacy Guardian optimize my internet connection?

Privacy Guardian is not an optimization product. Browsing speed on some particularly intrusive websites may be impacted due to the increased encryption required for protection. Websites with more invasive tracking force Privacy Guardian to encrypt more communication, which could potentially impact broadband speed.

Why after installing Privacy Guardian has my browser crashed, frozen or delivered error messages?

Privacy Guardian requires that you are running the latest software update/version of your web browser. Ideally before installing the Privacy Guardian browser extensions on each of your browsers, first make sure that they are fully up-to-date or update them immediately after installing Privacy Guardian. Second, the latest Windows updates should be fully applied for the software to work properly.
