Barnacle Apps ("we", "us", or "our") operates CustomerID for QuickBooks (the "Service"). This page explains what information we collect, how we use it, and your rights.
When you create an account and use our Service, we collect:
We use the information we collect to:
We connect to your QuickBooks account using OAuth 2.0. We read customer and invoice data solely to write Customer IDs back to your QB account. We do not store, sell, or share your QuickBooks customer or financial data with any third party.
Your account data is stored on Railway (a cloud hosting provider) and backed by a PostgreSQL database. All data is encrypted in transit via HTTPS. QuickBooks OAuth tokens are stored securely and used only to perform syncs on your behalf.
We retain your account data for as long as your account is active. If you cancel your subscription and request deletion, we will delete your account data within 30 days. To request deletion, email hello@barnacleapps.io.
You have the right to access, correct, or delete your personal data at any time. Contact us at hello@barnacleapps.io with any requests.
We may update this policy from time to time. We'll notify you of significant changes by email or by posting a notice on our website.
