Privacy Policy

Effective date: October 10, 2026  ·  Version 1.2

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. Studio also lets you export them
  • Sends your email address and license or trial code to nudgecss.com only when you activate a license or start a free trial. Nothing else leaves your browser
  • 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.

If you start a free trial or buy a license, the email address you enter is stored with our payment provider, Stripe, together with your trial or license status. Your email and code are also saved in Chrome's synced storage so the extension can confirm your license about once a day. We use your email to send your code and, only if you tick the box, occasional NudgeCSS tips and offers. You can unsubscribe from those at any time.

To have your email and trial or license record deleted, email hello@nudgecss.com.

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
storageTo save your panel preferences locally in your browser
host permission: localhost:8790Used only by the optional NudgeCSS Bridge feature, to hand a change to a Claude Code session running on your own machine. Scoped to that one local port, not to any other site or server.
host permission: nudgecss.com/apiTo verify a license or trial code and to request a trial code by email. Scoped to that one path on our own site.
host permission: Squarespace file serversUsed only by the optional Exact Clone feature, and only when you click it, to download a page's own style and font files that Squarespace's servers do not let a web page read directly. The files go into the zip saved on your computer and are sent nowhere else.

Third-party services

NudgeCSS does not integrate with any third-party analytics, advertising, or data collection services, and it sends data to a NudgeCSS server only for license and trial checks, described above. Purchases are processed by Stripe, and license and trial emails are sent through Resend. Separately, the optional NudgeCSS Bridge feature can send a change to localhost:8790, a local relay running on your own machine, so a Claude Code session you're running locally can read it. This request never leaves your machine and only fires when you explicitly click "Send to Claude Code."

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.
