Hi all,
I have created a web app to manage ones cryptoportfolio:
https://my-cryptoportfolio.renek.cc/Unlike many similar apps this one is completely open-source, ad-free and does not collect any cookies. The portfolios are saved in a database without any relation to the user, who created it. There is no need to log-in either. After setting the portfolio up you'll get a unique URL to access it.
The only reason for me to create the app was to learn about full-stack web development. Don't wanna earn a single dime with it. If it is useful for one or the other - great!
Please have a look if you want and give feedback.
Thanks and regards
Rene
