# Chrome Extension Permission Explained

Understand why the Supademo Chrome extension requests “Read and change all your data” permission and how we protect your privacy and keep data secure.

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.
