💻PowerBI Visual Architecture and Data Security

Astra is a Power BI visual plugin that runs 100% locally in your Power BI environment. It does not transmit, upload, or sync data to any external servers. This design allows Astra to be safely deployed in sensitive or air-gapped environments.

How Astra Works

• Runs inside Power BI: Astra executes entirely within Power BI’s built-in sandbox for custom visuals. No separate application or service is involved.

• Receives data from Power BI only: It visualizes data passed to it from the Power BI semantic model—nothing else.

• In-memory rendering: All data transformations and graph rendering happen in memory and are never written to disk or sent over the network.

Network Communication

Astra makes no network calls. This includes:

Activity	Status
API requests (fetch, XHR)	❌ Not used
WebSocket connections	❌ Not used
Telemetry or analytics	❌ Not used
CDN-hosted scripts	❌ Not used (all libraries are bundled)
File or disk storage	❌ Not used
