• Does not use analytics or tracking tools

• Does not serve advertisements

Information Stored Locally

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.

Data Retention and User Rights

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.

Data Security
