Hello altogether,

so far I have been tracking my portfolio and every single trade via Spreadsheet. However, as I collect more and more coins I am considering to switch to a portfolio tracking app (Cointracking, Blockfolio, Delta).

As these apps mostly function via APIs, I am a little worried since I can remember that the latest Binance hacking attempt (late Feb, early March, I believe) involved APIs - although I must admit that I am not exactly a tech-literate.

Therefore I wanted to ask, how secure these apps are (especially I was considering Delta) and if I can use them worrilessly?

Regards and thanks
