Effective Date: Sep 8, 2025
This Privacy Policy explains how DarkMad ("we," "our," or "extension") handles user data. DarkMad is a Chrome extension available on the Chrome Web Store, designed to modify the visual appearance of websites by applying different visual modes (dark, sepia, monochrome, invert) to reduce eye strain and improve readability.
Developer: fullpagedev
Extension ID: Available on Chrome Web Store
DarkMad is designed with privacy as a priority. The extension:
Does not collect any personal information
Does not track browsing history
Does not monitor user activity
Does not transmit data to external servers
Does not use analytics or tracking tools
Does not serve advertisements
DarkMad stores the following information locally on your device using Chrome's storage API:
Your visual mode preferences for websites you visit
Your site exclusion settings (websites you have chosen to exclude from visual modifications)
This information never leaves your browser and is used solely to remember your preferences across browsing sessions.
We do not share, sell, rent, or trade any information with third parties.
DarkMad requires the following permissions:
Storage: To save your visual mode preferences for websites
ActiveTab: To apply visual modes to the current tab
Scripting: To inject CSS needed for visual modes
ContextMenus: To provide right-click menu options for quick access
Host permissions (<all_urls>): To apply styles across websites you visit
These permissions are used exclusively for the core functionality of the extension: applying visual styles to websites.
All preference data is stored locally on your device indefinitely until you:
Uninstall the extension (which removes all stored data)
Clear your browser's extension data
Use the extension's settings to modify or remove site preferences
You have full control over your data at all times since it never leaves your device.
Since all data is stored locally on your device, it is protected by the security measures of your browser. We do not transmit any data over the internet.
We may update our Privacy Policy from time to time. We will notify you of any changes by updating the "Last Updated" date of this policy. You are advised to review this policy periodically for any changes.
DarkMad does not collect any personal information from anyone, including children under the age of 13.
