I built a portfolio manager

Hi everyone, I built portfolio manager app available for free on the Windows Store. Here is the address:
https://taluzone.com/talucrypt-download/

All your data entered will be stored on your computer , I believe it's the only portfolio manager for crypto where your personnal information (public key, amount of coin, total values etc...) are stored on the user's computer and not on a unknown server.

I don't like the fact that I have to share my information about all my crypto assets with a third party! So I built this portfolio manager app.

Feel free to use it and let me know if you think I could change something. If you like it, I am happy to implement the new features that you want.
