Nightly sync

How does bank sync work?

Expense Atlas uses Plaid, the industry-standard bank aggregation service trusted by Venmo, Robinhood, Chime, and most fintech apps you already use. The flow is simple and secure.

  1. Open Plaid Link — you click "Connect a bank" inside Expense Atlas; Plaid’s secure modal opens.
  2. Authenticate with your bank — for most major US banks this is OAuth: you log in directly on your bank’s site. Your credentials never touch Plaid or us.
  3. Plaid issues a read-only token — scoped to transaction history. No bill pay, no transfers, no write access.
  4. We pull transactions nightly — pending and settled. Each one is categorized automatically as it arrives.
  5. You can revoke at any time — from the connections page or directly in your bank’s app.
