Wallets like phoenix, breez and blixt are lightning nodes on your phone. You're in a custody of your funds. You have your seed phrase.
WoS is moreless a lightning bank where you have an account.
If WoS one day disappears, you'll get rekt.

Say I make a phoenix/Blixt/breez and something happens to my phone or the app company it self where would I go with my seed phrase to recover my funds/wallet?
