I am very new to this and just bought my own ens name and I have a dumb question. Where is the private key stored or the seed phrase?
Umm, that’s not related to ENS. the private key is something generated from seed phrase.

The private key and seed phrase is on the app (metamask or other) that has the ethereum address that you registered the ENS name with/under.
