What data you can access

• Accounts — IBANs, currency, product type, and holder details for business and personal accounts.
• Balances — current and available balances, refreshed on demand.
• Transactions — booked and pending entries with counterparties, references, and value dates.

Consent and coverage

Each authorisation stays valid for up to 180 days before the customer re-confirms, keeping long-running syncs uninterrupted. Sparkasse Mülheim a.d. Ruhr is one of 2,600+ banks reachable through the same platform across the EU and UK, so adding further institutions never means a new integration.

Privacy by design

The service is zero-knowledge: credentials are entered only on the bank's page and your account data flows through without being mined or retained for profiling. Because access relies on regulated open-banking rails, there are no eIDAS or QWAC certificates to buy, install, or renew.

Pricing

All of this runs at a flat ~EUR 3/month, with no per-call surcharges or setup fees — the same rate whether you connect one Mülheim account or spread requests across dozens of banks.
