Privacy Policy

Effective date: July 24, 2026  ·  Version 1.0

NudgeCSS does not collect, store, or transmit any personal information. Everything the extension does happens entirely within your browser, on your machine.

What NudgeCSS does and does not do

  • Reads computed CSS styles of elements you click, to display them in the editor panel
  • Stores your panel position and UI preferences locally in your browser using Chrome's built-in storage API
  • Tracks style changes within a session so you can undo them or export them
  • Does not send any data to external servers
  • Does not collect analytics, crash reports, or usage statistics
  • Does not track your browsing history or the URLs you visit
  • Does not read page content beyond what is needed to show CSS property values
  • Does not access passwords, form data, or any other sensitive information
  • Does not use cookies or any third-party tracking services

Where data is stored

NudgeCSS uses Chrome's built-in chrome.storage.local API to save UI preferences such as panel position and window size. This data never leaves your device.

Style changes you make during a session are held in browser memory and are cleared when you close the tab or reload the page. They are not persisted after the session ends unless you export them yourself.

Uninstalling the extension removes all locally stored data.

Why each permission is required

Chrome extensions must declare every permission they use. Here is what NudgeCSS requests and why.

activeTabTo access the page you are currently viewing so the editor can read and modify its styles
scriptingTo inject the editing panel and style overrides into the active page
sidePanelTo display the NudgeCSS editor as a Chrome side panel
storageTo save your panel preferences locally in your browser
tabsTo identify the currently active tab and route messages between the panel and the page

Third-party services

NudgeCSS does not integrate with any third-party analytics, advertising, or data collection services. The extension makes no outbound network requests.

The editor panel loads the Manrope typeface from Google Fonts. This request is made by your browser when the panel opens and is subject to Google's privacy policy. No user data is passed beyond what your browser sends with any standard font request.

Children's privacy

NudgeCSS is a developer tool intended for adults. It does not knowingly collect information from anyone under the age of 13.

Changes to this policy

If this policy changes, the updated version will be posted at this URL with a new effective date. Because NudgeCSS collects no personal data, changes are unlikely to affect you in any material way.
