veinito. is a fintech from Wrocław, Poland. We build Open Banking products for the whole European Union: for treasurers and parents, tenants and household budgets. All of them run on Enable Banking's AIS licence.
One shared foundation: the AIS licence of Enable Banking. On top of it, three products for very different people, each with its own brand and several languages from day one.
ClassKasaClass and preschool money collections without spreadsheets or chasing parents for transfers.
CzynszOKA tenant certificate backed by bank data, not by promises.
KasandroWhere the whole household's money goes. Every account in one view.
ClassKasa, CzynszOK, Kasandro and this site make up the veinito. group. They connect to your bank the same way, and each app has its own security page. The shared rules are written down in one place.

Security: ClassKasa →Where the whole household's money goes. Every account in one view.
Security: Kasandro →One security story: who logs in to the bank, who we rely on, what we check and where to report a flaw.
Group security →We are based in Wrocław, but we do not build for the Polish market alone. Open Banking works across the EU under the same PSD2 rules, so we design for many countries, languages and currencies from day one.
Account access is provided by Enable Banking Oy, a licensed account information service provider (AISP) supervised by the Finnish FIN-FSA and listed in the EBA register. We build products on top of it, always read-only.
Choose the account and how long access lasts.
You confirm consent in your own banking. Read-only.
Licensed AISP, over 2,500 banks across Europe.
Takes only the data it needs.
veinito. is an independent product company from Wrocław. We do one thing: turn bank account data into products that save people time and hassle. In Poland and across the EU.
We write about what we know: Open Banking, consent, account data and building products for the whole EU.
What Open Banking and PSD2 are, what an app with account access sees, how consent expires and is withdrawn, and how to check a licence.

No. Our products use only the account information service (AIS). They can read the data you agreed to share in your bank, but they cannot initiate a payment or change anything in your account. We never see your bank login or password either.
Enable Banking Oy, a licensed AIS provider supervised by the Finnish financial supervisor FIN-FSA and listed in the register of the European Banking Authority (EBA). It connects over 2,500 banks in more than 30 European countries.
You give consent in your own bank for a limited period whose length the bank sets, after which it has to be renewed. You can withdraw it at any time in your bank, and in the app where the product offers it (we describe each app separately on the security page).
Yes. We design them for the whole EU. ClassKasa runs in 15 language versions and in several markets, and Kasandro launches in Poland with versions for further countries. The bank connection covers over 2,500 banks in more than 30 European countries.
