I'd think twice before using Proton software. They froze my account about a year ago for no apparent reason. The account did get re-enable after a lot of back and forth.
Anyway bottom line. Avoid any centralized service or software that has ability to lock you out.
Indeed a risk worth considering but isn't this a non-custodial wallet so even if they ban you, you could restore your keys using some other software?
If wallet is non-custodial, then one should be fine. But I bet most will get sucked into using their other software. Why not just go with Sparrow wallet?
