Security and privacy

Your books are yours. We just keep them clean.

Penni connects through audited, read-only integrations. Your financial data stays in your accounts, and is never used to train AI.

How Penni protects your financial data

Six commitments, built in from day one.

🔑

OAuth 2.0, so we never see your password

Penni connects to QuickBooks through Intuit's secure OAuth. We never receive, store, or see your QuickBooks login credentials.

🛡

Never used to train AI models

Your financial data is used to do your books, and nothing else. It is never used to train AI models. Ever.

🏦

Your books live in QuickBooks, not with us

Penni writes to your QuickBooks, the system of record. Leave anytime and your books are right where they have always been.

🔒

Encryption in transit and at rest

All data is encrypted with TLS in transit and encrypted at rest. Access tokens are stored securely with row-level security.

📧

Email access is read-only and scoped

When you connect email, Penni reads only to detect financial transactions. It extracts the data and discards the raw email.

📦

Minimal data collection

We keep only what is needed to run your account. Extracted transaction fields, not your whole inbox or full statements.

Clear boundaries, by design.
