A question about a calculator? An error in the calculations? A partnership proposal? Get in touch.
Partnerships
Are you a financial institution looking to work with us? We describe the terms in the for partners section (in Polish).
Write to us - we will fix it and thank you. Every calculator shows the formula it uses, so you can check us in Excel. We encourage you to.
What is worth writing to us about
This address is read by a person, not a bot, so we take specific reports seriously. Three kinds of message are the most useful to us:
- An error in the calculations. Tell us which calculator, what data you entered and what result you think is correct. The calculation engine has a set of unit tests, so every report like this ends with a new test - whether or not the error is confirmed.
- A question about the methodology. If you disagree with an assumption we base a result on - for example the buffer for rate rises in the borrowing capacity calculator - say so. We describe all our assumptions on the about and methodology page, but a description is no substitute for a discussion.
- Outdated information in a guide. Regulations and rates change. We date every text - if you can see that a text has aged, let us know exactly what needs correcting.
What we will not do: we will not assess your borrowing capacity based on an e-mail, we will not advise you which loan to choose, and we will not put you in touch with a bank. We are neither an intermediary nor a financial adviser - we say so plainly in the terms of use. If you are looking for a specific offer, start with the borrowing capacity calculator, so you know what amount it even makes sense to ask for.
Writing about your personal data - access, correction or deletion? Use the same address; the procedure is described in the privacy policy.
