Not sure what you are afraid of here. Being an Airman you should report any abnormal that threatened safety of flight EG: turbulence, possible hard landing etc. I doubt anyone has the intent to spy on you as that would ultimately cost the airline a lot of money an all have the interest of saving it. A QAR/ACARS report on a hard landing after reported gives an initial report as to the G level. We commonly perform a manual download to confirm, document and decide the level of inspection required. If your judgment is in question why worry? The CVR or combined unit is only pulled when your company decides it is necessary to report and only the FAA in my case or as I suspect your CAA will read as they require it. Bottom line is live monitoring is a ridiculously expensive idea in today's age, esp. on the CVR.
