ThemeRatio Privacy Policy

ThemeRatio respects user privacy and is designed to operate locally within Firefox.

ThemeRatio does not collect, sell, transmit, or share personal information, browsing history, website content, analytics, telemetry, or advertising data with RatioWorks or any third party.

ThemeRatio stores user preferences locally using Firefox extension storage. These settings may include the selected browser theme, custom colors, Site Color settings, color strength, vibrance settings, and website exclusions.

Site Color and Site Accent are optional features. When enabled by the user, ThemeRatio may locally read the current website's hostname and visual theme or background color in order to generate a matching Firefox browser theme. This information is processed locally inside Firefox and is not transmitted to an external server.

Website access is optional and is requested only when a feature that requires website color detection is enabled.

ThemeRatio does not use analytics, tracking pixels, advertising systems, remote code, remote APIs, or a native desktop helper.

ThemeRatio's Firefox data collection declaration is set to required: ["none"] because the extension does not transmit collected information outside the add-on or local browser.

Users can disable Site Color at any time and may release the optional website permission through ThemeRatio's settings.
