How can I tell if my browser has Evercookies?

Use our evercookie checking tool to identify and analyze storage locations such as Local Storage and IndexedDB, which will show you what data is being stored.

What are the most effective methods for preventing Evercookies?

Effective methods include employing specialized software to clear cookies and configuring browser settings to block the ability to save data through scripts.

Persistent cookies, such as those created by Evercookie, pose significant privacy risks. Understanding the mechanism behind these cookies is crucial for effective data protection.

How Evercookie works

Evercookie technology cleverly establishes a unique identifier within the user’s browser storage. If any storage location is cleared by the user, other storages automatically regenerate the deleted data, effectively circumventing traditional browser cleaning techniques. This capability enables third parties to continuously track and gather data about the user’s online behavior.

Should these persistent cookies be identified using our tool, users are advised to employ specialized cleaning methods to effectively remove persistent cookies.
