SimpleFIN
SimpleFIN
OpenBooks can read a privacy-first, read-only bank feed over the open SimpleFIN protocol — an alternative to Plaid for institutions that support it.
What OpenBooks does with SimpleFIN
- Reads cleared transactions over the open SimpleFIN Bridge protocol.
- Gives privacy-conscious orgs a token-based alternative to aggregator logins.
- Read-only by design — no payment initiation.
What data flows
← OpenBooks reads
- Cleared transactions
- Account balances

Trust & security
- Access
- Token-based, read-only access you generate and can rotate. No bank credentials are shared with OpenBooks.
- Revoke
- Rotate or delete the SimpleFIN access token at any time to cut off access instantly.
- Encryption & handling
- Processed on OpenBooks-controlled infrastructure, encrypted in transit (TLS) and at rest. Never shared with third-party model providers (local-only data doctrine). See /security.
