Every account starts with a full-featured 3-month trial. No card required.
Your first-added car stays fully accessible for free — no action needed. Any other cars are locked for 3 days, during which you can upgrade to Pro to retrieve them. After the 3-day window, locked cars and their saved parts are removed from the web app and can't be recovered. You can keep using the free plan with one car for as long as you like.
