Hello,
There is an addon on anki computer version where you can hide a deck (so that it doesn’t appear on your frontpage. It does not delete the deck and you can unhide it when you want). the addon is called: Anki Hide Deck , and just makes the homepage A LOT cleaner when you have decks you don’t use but want to keep them.
It would be great if this was implemented in the mobile app!
Thank you for reading
You could do that on mobile by stuffing the decks you don’t want inside a new deck named, for example, “Hidden” like that:
select the deck you want to hide,
edit its name and add “Hidden::” in front of it, like that: Hidden::DeckIWantToHide
do the same with the other decks to be hidden,
collapse the “Hidden” desk.
This would work at least on AnkiDroid. 
This works but there is still a deck named hidden on your homepge
Then back-up and delete those decks.
You can also make a second profile for those decks.
Did ChatGPT write this? Is this a bot or an alt account of OP or what?
@edanki Can you confirm that @gusbear67 is not you?
It was just a random unhelpful bot post. We get them here too.
Call the deck zHidden instead, and it will sort to the bottom of your Decks list, out of your way.
This has been proposed a number of times over the years, in each of the apps. [For starters, see the list of “Related topics” at the bottom of this page].
One reason it is unlikely to be taken up is that the order of decks in the decks list matters to the scheduler that puts together your study session. Having invisible decks would create a lot of unexpected behaviors.
For another reason, I’ll just quote one of the developers –
One instead of how many?
