DuoNex Privacy Policy

Effective Date: April 18, 2026

DuoNex AI LLC ("DuoNex," "we," "us," or "our") operates the DuoNex business intelligence application. This Privacy Policy explains how we collect, use, and protect your information.

Data We Access

DuoNex accesses your QuickBooks Online financial data solely to respond to your queries. We do not permanently store your QuickBooks financial data — it is fetched live per query and not retained on our servers.

Data We Store

We store only your encrypted OAuth access token, refresh token, and QuickBooks company ID (realmId) to maintain your authorized session. Tokens are encrypted at rest using AES-128 encryption.

AI Processing

Your questions and relevant financial context are processed by OpenAI's API to generate answers. Your financial data is never used to train AI models.

Data Sharing

We do not sell, trade, or share your personal or financial information with third parties except as required to operate the Service (OpenAI for AI processing, Intuit for QuickBooks Online access).

Your Rights

You may disconnect DuoNex from your QuickBooks account at any time through the app or through your Intuit account settings. Upon disconnection, your stored tokens are deleted within 30 days.
