CSS Viewer Privacy Policy

Last Updated: April 9, 2026

This Privacy Policy describes how we collect, use, and share user data. By using CSS Viewer, you agree to the terms of this Privacy Policy.

1. Data Collection

CSS Viewer collects the following types of data:

  • User Activity: The extension's core function requires it to handle user activity only when it is active. This includes:
    • Mouse Position & Clicks: To know which element you are hovering over or selecting to view its CSS.
    • Scroll Events: To ensure highlights and the popover stay in the correct position as you scroll.
    This data is used exclusively on your local computer, in real-time, to make the extension work. It is never stored, logged, or transmitted.
  • Website Content: To display CSS for the hovered element, the extension must access website content only when you activate it. This includes:
    • DOM & Computed Styles: Reading the page's structure and computed CSS to display matched rules, computed values, and generate SCSS, Tailwind, and JSX output.
    This data is only read from the page to power the CSS inspection features. It is never stored on any server or transmitted externally.
  • Local Preferences & Settings: Your extension preferences are stored locally on your device using Chrome's storage APIs. This data is never transmitted to any server.
  • License Information: If you have purchased a Pro license, your license key and activation status are stored locally on your device and verified with Gumroad's servers to confirm your purchase.

We prioritize your privacy and do not collect or store any information beyond what is necessary for the extension to function. We never resell your personal information.

2. How We Use Data

We use the collected data for the following purposes:

  • License Validation: We verify your license key with Gumroad's servers to confirm your purchase and ensure proper activation limits are respected.
  • Feature Access: We use your license status to enable or disable Pro features within the extension.
  • CSS Inspection: We read the DOM and computed styles of the active page to display CSS information for the element you are hovering over. All processing happens locally in your browser.
  • Preference Storage: We store your settings locally so your preferences persist across sessions on the same device.

3. Data Sharing

We share the collected data with:

  • Gumroad: We send license validation requests to Gumroad's servers to verify the purchase status of Pro users. You can review their privacy practices at gumroad.com/privacy.

Our data sharing practices are strictly limited to the service listed above. We never share, distribute, or resell your personal information to any other services or companies.

4. Data Storage

CSS Viewer stores data as follows:

  • Local Storage: Your license key, Pro status, and extension preferences are stored locally on your device using Chrome's secure storage APIs.
  • No Server Storage: We do not store any personal information on our servers. All data remains on your device or with Gumroad for the purposes of license validation.

5. Third-Party Services

CSS Viewer uses the following third-party services:

  • Gumroad [gumroad.com]: Handles all payment processing, license key generation, and purchase verification.

6. User Rights

Users have the right to access, rectify, or delete their personal data. Because CSS Viewer stores all data locally on your device, you can clear it at any time by removing the extension or clearing extension storage through your browser settings. If you wish to exercise any rights related to data held by Gumroad (such as purchase records), please contact Gumroad directly.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date at the top of this document. You are advised to review this Privacy Policy periodically for any changes.
