I have paid for the app already, why I need to pay again for the web portal?

We use the Microsoft Azure platform to host user data and do all the data conversion logic. We need to pay Microsoft a lot every month for that service. We want an organic and sustainable business model that benefits both sides.

We do not have an "Angle fund" that helps us "burn money" to increase the user base rapidly, but we are more sustainable and have complete control over improving ATracker functions and services.
