Link-do links never expire.

When you delete a link, it stops working—anyone who clicks the link or scans the associated QR code will receive a 404 error message. Instead, if you hide the link, the shortened link will be concealed in the Link-do app but will still function. Engagement data remains in Link-do.

Links using a custom domain will continue to work as long as your DNS still points to Link-do, and the custom domain is connected to your Link-do account.
