Cookie Isolation refers to the practice of keeping cookies and other website data completely separate between different browser profiles or sessions.

Why does this matter?

Cookies are small pieces of data that websites store in your browser to recognize and remember you - for example, keeping you logged in or saving your preferences. If cookies are not isolated, data from one profile or session might “leak” into another. This could cause problems such as:

• Cross-profile tracking: A website could recognize you across different browser profiles.
• Security risks: Sensitive information (like login tokens) from one session could become accessible in another.
• Loss of privacy: Advertisers or third parties might combine data from different sessions to build a more complete profile of your online activity.

With cookie isolation enabled, each profile or browsing session* has its own independent set of cookies and storage. This means that logging into a site in one profile does not affect, expose, or interact with cookies in another profile. It ensures privacy, security, and prevents unwanted data mixing.

^{*When we say profile, we mean a separate browser profile - for example, a work profile and a personal profile in Chrome or Firefox. Each profile has its own saved cookies, passwords, and settings.}

^{*When we say browsing session, we mean a temporary browsing state, such as a normal window versus an incognito/private window. A session keeps its own set of cookies only while it is active, and those cookies disappear once the session ends.}

Relevance for Kameleo

Kameleo anti-detect browser uses Cookie Isolation so each virtual browser profile has its own cookie storage. That means when you run two profiles at the same time, they do not share cookies. This helps avoid cross-profile tracking. If you export a profile (to a .kameleo file), its cookies are exported with it and remain isolated when moved.

Why It Matters

Without isolation, websites might combine data from multiple sessions or profiles to build a larger fingerprint or history. With isolation, each profile looks like a separate user. This is especially important when doing web scraping, multi-accounting, or other automated tasks where leakage between profiles could reveal links and lead to detection.
