Junk Yard · Auto-clear, pins and deleting
How long do scraps stay on the Junk Yard?
Short answer: Each scrap clears when its own countdown (shown as "Clears in…") runs out. New scraps use the Auto-clear setting — 1 day unless you change it — and any scrap can be set from 5 minutes to 6 months.
Every scrap has a lifetime, and each card shows a live countdown such as "Clears in 3h". When the countdown runs out, the scrap is tidied away. New scraps get the default you choose under Auto-clear new scraps after in Settings → Junk Yard — 1 day unless you change it.
You can give any individual scrap a different lifetime from its lifetime/pin menu, from 5 minutes up to 6 months. Pinning doesn't stop the timer; a longer lifetime does.
