Privacy Policy

Effective: June 17, 2026

Data Collection

NovaStyle does not collect, transmit, or sell any personal data, browsing history, or usage information. The extension operates entirely locally within your browser.

What data is stored?

• CSS modifications — The styles you create are saved to your browser's local storage (chrome.storage.local / browser.storage.local), keyed by domain name. This data never leaves your device.
• Extension settings — Your preferences (theme, visible editors, panel position) are stored locally in the same way.

No network requests

The extension makes no network requests to external servers. All features — element inspection, style editing, persistence, and export — function without internet connectivity.

Permissions

NovaStyle requests the following permissions:

• storage — To save your CSS modifications and settings locally.
• activeTab — To read and modify the CSS of the currently active tab when you activate the extension.
• <all_urls> — To inject the style editor into any webpage you choose to inspect.

These permissions are used solely for the extension's core functionality and cannot be used to exfiltrate data.

Third parties

NovaStyle contains no third-party analytics, tracking, telemetry, or advertising code. The only external dependency is the webextension-polyfill library, which normalizes browser API access and does not make network requests.

Changes

If this policy changes, the updated version will be posted here with a new effective date.
