I love the effort and attempt to solve a real problem, but the implementation is frankly dangerous. Not your keys not your coins. This Crypto Plans service has complete control of all of your funds and there is nothing at all stopping them from spending them.
Using multiple signers is a much safer approach available with a service like
Casa App where neither your loved ones nor Casa have enough key material on their own to spend your funds, but if you we incapacitated they could come together to recover your funds and support you through the process
