But why did you decide to used blockstream wallet out of many open source custodial wallets? I'm curious how you see this and still like it.
It's a non-custodial wallet and not custodial for correction only.
They collect your data for wallet improvement but even with "don't collect data", I won't trust such wallet that need users data for wallet improvement.
There are many alternatives to this Blockstream such as Bluewallet, and Electrum for android device, these are available on mobile and support what you want.
Usually those data are typically referring to anonymous, aggregated usage metrics rather than sensitive, tracking which buttons, screens, or any features users interact with the most, helping them prioritize future updates. As well as the platform if ios or android for statistics reason. Anyway, it's open source, if im not mistaken.
