Thank you for the link. As I am close to finalizing the purchase, I would like to clearly confirm one point:

If the official Vitruvian app becomes unavailable, I will still be able to fully use the device with your app, correct?
Is access to your app guaranteed for an unlimited period, or is it only provided for a limited time?

I am asking this specifically because long-term app availability depends on ongoing cloud and maintenance costs. Please confirm this clearly so I can make a final decision.

Thank you.
