# Chrome Extension Permission Explained

When users install or update the Supademo Chrome extension—whether they’re new or long-time users—they may see a permission request that reads:

**“Read and change all your data on all websites.”**

This phrasing can feel alarming, so here's a clear, user-centric breakdown:

#### Why We Need It

* This permission allows Supademo to capture screenshots or HTML recordings of the websites you visit—core functionality needed to **record Supademos**.
* Just like video recording platforms, we require this permission to inject toolbar elements, popups, and overlays, and to access the webpage content that you record.

#### How We Protect Your Data

* Your data remains **private and secure**—all captured content is transmitted over TLS and stored securely.
* Nothing is shared publicly unless *you* choose to via a Share link.
* We take your privacy seriously, and we're also [**SOC 2 compliant**](https://supademo.com/security), ensuring trusted data handling practices.
