Is there a way to export every single flight I’ve ever made on SimBrief, kind of like a full data export?
Unfortunately no, Simbrief only stores a few months worth of flight history.
But you can view your flights over the past month here, for what it’s worth: https://www.simbrief.com/system/dispatch.php?viewflights=1&showall=1#flighthist
Best regards,
