PRIVACY POLICY

At "Add CSS - Custom Style Injector" ("Extension"), we prioritize your privacy and data security. Our extension does not collect, store, or share any personally identifiable information (such as names, emails, or browsing history).

1. Data Collection and Usage

To provide a reliable and functional experience, the extension only uses "functional data" as described below:

a) Locally Stored Data

Your custom CSS codes, URL patterns, and settings are stored only on your own browser using Chrome's chrome.storage.local API. This data never leaves your device and is not accessible by us.

b) Network Requests

Unlike many other extensions, Add CSS does not connect to any external servers to fetch or send data. It operates entirely locally on your machine.

2. Permissions and Justifications

Our extension requests the following permissions in the manifest.json file:

  • "storage": Required to save your custom CSS styles and settings locally in your browser.
  • "host_permissions": ["<all_urls>"]: Required to inject your custom CSS into the websites you specify. Without this, the extension cannot modify the appearance of pages.

3. Data Security

Since "Add CSS" does not collect personal data, there is no sharing or selling of information. All styles are processed locally on your browser and remain under your full control.

4. Contact

For any questions regarding the extension, you can contact us through our contact page.
