Clarity on PGP support

Hello! I’m trying to figure out the best way to use OnlyKey for my existing PGP key management.

A common setup for PGP keys is to keep the primary keypair stored somewhere and use subkeys to sign and encrypt as needed. If I upload my pre-generated primary keypair to OnlyKey, will it also keep track of subkeys I generate, or am I better off storing my primary keys elsewhere and only adding a signing subkey and encryption subkey to the OnlyKey?

Thanks for this fantastic device, by the way!

OnlyKey just stores the raw keys and whether to use them for signing or decryption. You can also assign key labels to give your key an identifier. Then in the OnlyKey agent you specify which key to use. All the information on primary and subkeys is managed by software (GnuPG).
