As long as your account is active the data will stay indefinitely in your SPOTadventures account. Keep in mind that this is a great way for you to archive your adventures!  But your data still only stays live within your SPOT account for 30 days so please remember to save your trips on a regular basis.  It is a short simple process and will allow you to keep that data indefinitely.  Once you create an adventure using your SPOT waypoints, your adventure is stored and saved to your SPOT Adventure account.
