Can you please tell me where is the data storage located? Hopefully EU. What safety regulations do you implement.

I have very sensitive data, like birthday certificates etc. (children and adult).

FormNX provides you with GDPR-compliant forms, not only that but the data stored is highly secured & password-protected in the EU server region. To enhance the security further we also have 'Sensitive Data' setting for each field which will make them even more secured by encrypting.
