How Sparrow uses your bank access
Last updated 12 November 2026
When you connect a bank account you grant Sparrow access to read your financial data so we can sort and show your spending. This is exactly what that access does — and what it can never do.
What we access
Read-only access to your transaction history and account balances. Sparrow can read your financial data. It can never move your money, make a payment, or change a transfer.
How long access lasts
Access is ongoing and refreshed automatically (typically daily) until you tell us to stop. You can revoke it at any time from Manage Connections in Settings, or on my.akahu.nz.
- Read-only, always
- Ongoing until you stop it
- You stay in control
Akahu & open finance
Sparrow is built on Akahu, New Zealand’s open finance platform. We use Akahu to securely fetch transaction data from your connected bank account. Find out more about Akahu at the link below.
