# Privacy Policy — Classroom Dark Mode

  **Last updated:** 2026-05-25

  Classroom Dark Mode does not collect, store, or transmit any personal data. This
  document explains exactly what the extension does and does not do with your
  information.

  ## What the extension stores

  The extension stores two user preferences via the Chrome `storage.sync` API:

  - **`enabled`** (boolean) — whether dark mode is currently on or off.
  - **`accent`** (string) — your chosen accent color: `green`, `blue`, or `orange`.

  That is the entirety of the data the extension touches. No personal information, no
   browsing history, no Google Classroom content, no identifiers of any kind are
  read, stored, or transmitted.

  If you are signed into Chrome with sync enabled, these two values are synchronized
  across your devices by Google's own sync service. Classroom Dark Mode operates no
  server and has no access to that synced data beyond reading and writing your own
  preference on your own device.

  ## What the extension does NOT do

  - Does not collect personal information of any kind
  - Does not track browsing activity or behavior
  - Does not communicate with any external server
  - Does not include analytics, telemetry, or advertising of any kind
  - Does not read, modify, or transmit the contents of any Google Classroom page
  - Does not load any remote code — all JavaScript and CSS is bundled inside the
  extension package

  ## Permissions explained

  The extension declares the minimum permissions required to function:

  - **`storage`** — to save your on/off toggle and accent color preference so they
  persist across sessions.
  - **`https://classroom.google.com/*`** (host permission) — to apply the dark theme
  stylesheet exclusively on Google Classroom pages. No other origin is accessed, and
  no data is read from these pages.

  ## Data sharing

  We do not share any data with third parties because there is no data to share. The
  extension has no backend, no analytics provider, and no advertising partners.

  ## Changes to this policy

  If this policy is ever updated, the "Last updated" date at the top will reflect the
   change. Material changes will also be noted in the extension's listing on the
  Chrome Web Store.

  ## Contact

  For questions about this policy, please open an issue on the project's public
  repository or contact the developer through the Chrome Web Store listing.
