My Arrow Setups
Stored locally on your device — no account, no server. Clear your browser data and they're gone, so export a backup if you want to keep them.
How this works
Every calculator in the Simulation Lab can save its result here with one click — the exact inputs and outputs get written to your browser's local storage, the same private storage web apps use to remember settings. Nothing is uploaded anywhere; there's no account, no server and no sign-in, which also means we can't recover a lost setup for you if you clear your browser's data.
Each saved setup keeps a Load Full Setup link that reopens the calculator with every field pre-filled, plus a short summary card so you can compare setups at a glance without reopening each one. Because everything lives in this one browser, on this one device, it won't follow you to your phone or a different computer — use Export backup to save a JSON copy you can move over, or Import it back in if you switch browsers, wipe your cache, or want to hand a specific setup to someone else.
Will my setups still be here next time I visit?
Yes, as long as you use the same browser on the same device and don't clear your site data. Private/incognito windows and "clear cookies on exit" settings will wipe them, which is why the export button exists.
