Xeropan is connected with the GOOGLE and APPLE payment system, the payment is carried out through them.  Both Google and the App Store have very STRINGENT RULES for the downloaded applications, and for the payment within them as well.

Xeropan also had to go through the inspection process which takes several weeks to get into Google and Apple’s systems to prove itself as a safe application (as any other application).

If you trust those systems, you can trust XEROPAN as well.
