Consent and coverage

Sparkasse Hattingen access follows the EU PSD2 standard: a single consent stays valid for a maximum of 180 days, after which the account holder simply re-approves. open-banking.io connects 2,600+ banks across the EU and UK, so Sparkasse Hattingen sits alongside the rest of your financial stack under one API.

Privacy by design

The platform is zero-knowledge and certificate-free. Your credentials are entered only at Sparkasse Hattingen's own login — never with us — and we never store or inspect your banking secrets. You stay in control of every token and can revoke access whenever you like.
