Application storage

When you add a channel it is added to your roku account. All boxes on your Roku account will get the channel. If the channel requires you to link, then the box itself is linked and registered.
To clear the information and fully remove all channels from the individual roku box, use a paperclip for 30 seconds pressed on the 'reset' hole to factory default the box.
To remove the box listing from your roku account, go to roku.com and remove it there. If you are removing it from your roku account on the website, it's a good idea to factory default the box too.

In fact I don't want to remove the channels from the box, that is why i asked before deleting the account 🙂
Thank you for the answer.

If you mean your CC info you entered when you set up the account, you can just delete that.
Your box will remain linked to your Roku account. You just won't have a payment method.

Yes that is what i meant. But I thought that it was compulsory to have one linked... Well I think I will just remove it then.
Thanks very much.

No, not compulsory. Your account will be unaffected if you delete the info, and Roku keeps no record of it.
