About Zunavek

Zunavek publishes free tools and guides for browser privacy, network information, DNS, and email security. Tools expose technical observations so you can investigate a connection or configuration and understand the limits of the result.

Who publishes the guides?

Guides are published by Zunavek. Product comparisons describe documented provider features and link to their sources. When we report a test, its conditions and limitations should accompany the result.

Evidence and corrections

Technical guidance should identify primary documentation, distinguish observations from conclusions, and explain unavailable checks. Publication dates identify the original article; update dates indicate a substantive revision. Provider features and browser settings can change after publication.

Report an incorrect result or outdated instruction to [email protected]. Include the page URL, browser version or relevant public configuration, and expected behavior. Remove private email content, tokens, and other secrets.

Using the tools

Scores are diagnostic aids, not certifications of security, anonymity, or mail delivery. See our methodology for scope and limitations, our privacy policy for data handling and analytics, and our affiliate disclosure for commercial links.
