Is this the info from your friend? Did they allow to make it public? Why the list of credit card use is so short? (I expect like 50 purchase per month x 12 months pr year x 5 years [IIRC from 10 seconds ago when I skimmed the pdf] = 300.)
This is synthetic demo data kept it short so people could see the methodology clearly. Real reports have way more transactions (platform handles 10k+ via Celery).
It's meant to be public as a sample showing the output format. Real client data is obviously private/encrypted.
