Yes. As long as you use Trezor Suite, you can keep the label data locally. You can also use Google Drive if you trust them more for some reason. All the metadata is automatically encrypted with your private key.
So the Trezor Suite takes the private key of my Bitcoin Wallet to encrypt the metadata? So if i have 3 different addresses aka wallet1, wallet2 etc. the names of the wallets tx would be encryptet with private key1 pk2 etc?
or Do you mean my password/Key for the Trezor?
Ist it clear in which folder all that data lies? For migrating to another machine?
And of course i don't trust evil corp Moving away from Us services and especially cloud services...
