Privacy Policy — Dark Mode for Chrome

Last updated: April 7, 2026

What data we collect

None. Dark Mode for Chrome operates entirely locally in your browser. We do not collect any personal information, browsing history, page content, or usage data.

Data storage

All settings and preferences (selected theme, brightness level, per-site enable/disable state) are stored locally on your device using Chrome's built-in storage API (chrome.storage.local). This data never leaves your browser.

Permissions

Dark Mode for Chrome requests only the minimum permissions necessary to function:

• activeTab — to apply dark mode CSS to the current tab when you click the extension icon
• storage — to save your theme and brightness preferences locally
• scripting — to inject the dark mode stylesheet into pages via the standard Manifest V3 API
• alarms — to power the optional scheduled dark mode feature and periodic Pro license validation
• Host permission (<all_urls>) — required so a tiny content script can run at document_start on pages where you have enabled dark mode. This script reads a synchronous sessionStorage flag and injects a dark background before the page paints, preventing the flash of white on navigation. No page content is ever read, collected, or transmitted — the script only writes a style element.

No permission is used to collect or transmit data.

Third-party services

Dark Mode for Chrome does not use any third-party analytics, tracking, or advertising services. Pro subscriptions are processed by Stripe on a separate checkout page; Stripe's privacy policy applies only to that transaction.

Changes to this policy

If we ever change this policy, we will update the date above. Any significant changes will be communicated through the extension's update notes.
