Amazon Deletion: Kindle

I have a kindle already, but I do not buy books off amazon, and haven’t for a long time because they dont support the authors well and I want to support small businesses / libraries.

I want to fully delete my amazon account but it says in the confirmation page that it’ll wipe my kindle information completely.

•How does this work if the books on my kindle are not on loan or purchased off amazon?

•If I delete my amazon account will I no longer have access to the kindle app and/or “send to kindle” functions?

So sorry if this is repetitive, I am sure a lot of people are asking the same stuff, but I wasn’t comfortable asking in the “r/kindle” sub.
