Short version

We collect nothing

GrayMode does not collect, store, or transmit personal data, browsing history, or usage analytics. The extension works locally and is designed to stay boring from a data-collection perspective.

Privacy details

Overview

GrayMode applies grayscale filters to distracting websites so they feel less stimulating and easier to leave.

This page explains which permissions it needs and how that access stays constrained to your browser.

Permissions Explained

  • storage stores your settings locally, including enabled categories, custom blacklist entries, and intensity.
  • activeTab helps detect the site you are currently viewing so GrayMode can decide whether to apply grayscale.
  • host_permissions: <all_urls> lets the extension inject the grayscale CSS filter on the websites you choose.

Local Storage Only

Your settings live in chrome.storage.sync.

  • Data stays inside your browser profile.
  • If Chrome sync is enabled, your browser may sync settings through your own Google account.
  • We do not have access to any of that data.

Network Activity

GrayMode makes zero network requests. No API calls, no analytics beacons, no background telemetry.

The extension keeps working offline because there is no backend infrastructure behind it.

What we do not do

✓ We do not track your browsing history.
✓ We do not collect analytics or usage events.
✓ We do not show ads or inject sponsored content.
✓ We do not sell data because there is no user data to sell.
✓ We do not require account creation.

Changes

If this policy changes, this page will be updated. Given the product direction, significant privacy changes are unlikely.
