# Security and data protection

How Retriever protects your data: Intuit-approved OAuth to QuickBooks, encryption in transit, and least-privilege Google Sheets permissions.

## Transport

Data is sent using HTTPS.

## QuickBooks access

Retriever connects to QuickBooks Online through Intuit's OAuth flow. You grant access to the companies you choose.

## Google Sheets access

Retriever requests the Google Sheets permissions it needs to write report data into the spreadsheet you have open. It does not need access to your full Google Drive.
