This beta is designed so the business file you select is processed in the browser on the computer you are using. It is not posted to SIOP OS or Cloudflare by the application.
The guided-tour player requests a fixed narration clip by step number. The server already contains the instructional text. The request does not include the contents, field names, results, mappings, or values from your business file.
Selected CSV contents, field mappings, analysis results, and local beta preferences remain in the browser environment used for the session unless a future beta explicitly introduces a different storage feature.
No software can promise that a device, browser, network, or service can never be compromised. This beta instead minimizes the data path: it does not provide a server endpoint that accepts customer CSV data, and its browser security policy allows network connections only back to this SIOP OS site.
