ThemeRatio uses Firefox's native theme APIs. It does not replace webpage content, inject advertising, use analytics, or require a native desktop helper.

Website color detection is optional. When enabled, ThemeRatio analyzes visual theme colors locally in Firefox to generate a matching browser theme. ThemeRatio does not transmit browsing data, website colors, hostnames, settings, or telemetry to external servers.
