Reading the user manual, (see the company's website), it seems that storing a record of your tests is optional. (It is not imposed upon you the way it is by other, paternalistic, manufacturers such as Lifescan.)
You prevent a test being recorded by pressing the button after the strip's in. This is described in the manual as "performing a control test". You can delete all current stored results as part of setting the date/units.
The fact that the strips are merely extremely expensive, rather than extortionately expensive, makes the thing even more attractive.

Dear Anne,
Like I usually try to do, I did cite my source. It's linked under the word "experts."
