Blackout does not collect, transmit, sell, or share any user data.
Reads the page you're viewing, via a content script, solely to apply a visual dark-mode filter to it. Page content is never read for any other purpose, never copied, and never sent anywhere.
Stores your preferences (global settings, per-site overrides, schedule)
using your browser's built-in storage.sync API. This data
stays inside your browser and, if you're signed into your browser
account, syncs across your own devices the same way your bookmarks do
— it is never sent to us or any third party.
No analytics, telemetry, or tracking of any kind. No network requests to any external server. No collection of browsing history, page content, or personal information. No ads, no third-party scripts.
| Permission | Why it's needed |

storage |
Save your dark mode settings and per-site overrides locally/synced. |
activeTab |
Let the popup know which site you're currently on, for per-site controls. |
| Access to all sites | The extension injects its dark-mode style sheet into any page you
visit, since that's the whole point of the extension. It only ever
writes a <style> tag; it does not read or
exfiltrate page content. |
If this policy ever changes (for example, a future optional paid tier introduces a license-check network call), this document will be updated first and the store listing will note the version it applies to.
