Is the private key of metamask saved on its own server?

about the ethernet square wallet.
metamask is a Google plug-in. All created accounts, transfers and so on communicate through json rpc, so ask if the server also keeps this copy of the private key.

of course not, they only save the public key, you save the private key.


the private key or mnemonic exists only in your local area. Metamask signs the transaction locally with your private key and then sends it to the ethernet network.
