user137214: I found a vanity address with this verified tool: https://github.com/JeanLucPons/VanitySearch
And now I hold my private key, with BTC I am used to only the recovery seed and I don't know what position I am currently in.
Can I get the seed somehow or does the private key replace it?
The primary thing I'm concerned about is I want to receive all funds in the store at my own address and I want it to be as secure as the address I get in any other wallet.
Thank you very much for your time.
EDIT:
I'm doing research, but this topic seems very complex to me and I'm afraid of getting something wrong and putting myself at unnecessary risk, but what I've understood so far: a private key is +/- the same as a seed except that the seed "controls" the entire wallet, while the private key only controls a specific address, so I should have the funds safe even now and no further steps are needed.
I imported the private key into Electrum and encrypted the file.

Generating random private keys is difficult and sometimes old tools are vulnerable.
