What is an evercookie?
Evercookies are persistent tracking mechanisms that use multiple browser storage techniques to make them extremely difficult to remove.
What is an Evercookie?
Evercookie produces highly persistent and tenacious cookies in your browser. This javascript API is used to identify you even if you try to clear standard cookies files, Flash cookies (Local Shared Objects or LSOs), and others. This persistence is achieved by using different types of storage mechanisms to put the cookie data in several places on your local browser simultaneously. Moreover, if you try to remove any of these cookies, evercookie recreates them using each mechanism available.
Privacy Concerns
Evercookies can be used to track users even after they've cleared their browser cookies. This persistent tracking raises significant privacy concerns as it can be used to build detailed profiles of your browsing habits.
Difficult to Remove
When a user deletes a cookie from one location, evercookies can regenerate it from the other storage locations. This makes them particularly resilient and difficult to completely remove from your browser.
How to protect against evercookies
Protect your privacy by preventing persistent tracking with these effective solutions.
Use VPN Master Pro
Our VPN service includes built-in tracking protection that helps prevent various tracking methods, including evercookies, from identifying and following you across the web.
Clear All Browser Data
To remove evercookies, you need to clear all browser data, including cookies, cache, local storage, and other storage mechanisms. Use your browser's privacy settings to perform a complete cleanup.
Use Private Browsing
Private browsing modes (like Incognito) can help prevent persistent cookies by automatically clearing storage when you close the browser. Combine this with VPN Master Pro for maximum privacy.
How evercookies work
Understanding how evercookies function helps you better protect your privacy online.
When you visit a website using evercookies, it stores the same tracking ID in multiple storage locations.
If you delete cookies from one location, the evercookie script can recreate it from the other storage locations.
VPN Master Pro helps protect against tracking by masking your IP address and providing tools to block tracking scripts.
Our service also includes regular privacy cleanups to help remove persistent tracking mechanisms from your devices.
