Junk Yard · Auto-clear, pins and deleting
Can a Junk Yard scrap stay forever?
Short answer: No. The longest lifetime a scrap can have is 6 months; there's no "never clear" option. Save anything you need longer somewhere permanent.
No — the longest lifetime is 6 months. There's no "never" setting, because the Junk Yard is designed to clear itself rather than turn into another place where things pile up.
For anything you'll need beyond that, copy it out into a document, notes app or folder. Also bear in mind the board keeps a limited number of scraps, so on a busy board the oldest can drop off before its timer ends. See How many scraps does the Junk Yard keep?
