Your financial data doesn't stay with Plaid — it flows to the app you're connecting to, and Plaid's agreements with those developers (not your direct agreement) govern how they must handle it.
Plaid processes sensitive financial data — including bank account credentials, transaction histories, and account balances — on behalf of thousands of third-party applications, meaning its policies directly affect the privacy and security of your banking information. Consumers who have connected a bank account to any app using Plaid have agreed to allow Plaid to access and share their financial data with that application and potentially other parties under the terms described. You can review and manage which apps have access to your financial data through Plaid's consumer portal at my.plaid.com.
