This page explains what happens to the numbers you enter in the calculator.

Who is responsible

The calculator is run by Flexity s. r. o., Company ID 35 731 389, Ľuda Zúbka 2, 841 01 Bratislava-Dúbravka, Slovakia, registered in the Commercial Register of District Court Bratislava I, Section Sro, Insert No. 15884/B.

For anything about your data, write to info@flexitylab.com.

While you calculate

The calculator runs in your browser. The numbers you enter are kept only in the page address, so you can share or bookmark the calculation. When you open such a link, the numbers reach our server as part of the page address, but the server does not use or store them. The calculator asks for no name, email or other personal details.

Your rights

Under the GDPR you can ask us what data we hold about you, and ask us to correct or delete it. Write to info@flexitylab.com.

You can also complain to a data protection authority, in Slovakia the Office for Personal Data Protection of the Slovak Republic, or the authority where you live.

Analytics

We do not use cookies. If we measure how the calculator is used, we use cookie-free, aggregate statistics that contain no personal data. They may include page views and a few actions, such as a copied link or a printed report. They never include the numbers you entered. If your browser sends Do Not Track, nothing is counted.
