Wardline privacy policy

Effective date: 2026-09-12 (version 1.0)

Wardline is a Windows application that blocks advertising, tracking and malicious domains by filtering DNS requests on your computer. This policy explains what the application does with data. In short: your data stays on your device.

What the application processes

DNS requests. Every application on your computer asks the system which address belongs to a domain name. While protection is on, Wardline answers those requests locally: names on your filter lists or deny rules are blocked, all other names are forwarded to the DNS provider you selected in Settings, DNS upstream.

Query log. The application keeps a list of recent requests (time, domain, type, whether it was blocked and by which list) so you can see what happens and add rules with one click. This log is kept in the computer's memory only, is never written to disk and disappears when the protection service stops. You can turn it off in Settings, Query log, or on the Query log page.

Statistics. Counts of blocked and allowed requests per day and the most frequently blocked domains are stored on your computer (%ProgramData%\Wardline) so the dashboard can show them.

Settings. Your filter list choices, rules and preferences are stored on your computer in the same folder.

Browser cleaner. On request, the application measures and deletes cookies, cache and temporary files in the browser profile folders of the current user. It reads folder sizes only, never the contents of those files, and nothing about them leaves the computer.

What leaves your computer

Nothing else is sent anywhere. Wardline has no account system, no telemetry, no crash reporting and no advertising.

Your choices

Children

The application is not directed at children and collects no personal information from anyone.
