It requested for email and password, which I do not like. I prefer wallets that I can be able to access using just seed phrase and nothing else than wallet file.
I use proton username and password which has not subscribed before and it brought this up on my mobile phone:

Because I did not subscribe and it brought up 'Updating your account' and did not update anything nor load any wallet. So no wallet until you subscribe.
I think if you subscribe, you may also be able to access their paid VPN (but I do not know) and their other products and services. But I can use other reputed noncustodial wallet like Electrum, Bluewallet, Sparrow, Unstoppable, Metamask and some other wallets without even using email and password and and they are free.
