I think it's curious that they claim to "destroy' the images after "a week to 30 days". If there are about 1 billion mailed items each year, and it takes 50 kilobytes to store an image (wild ass guess, and assuming some compression), that would amount to 50 terabytes of data: A bit more than 4 of the largest-capacity of hard drives currently sold. https://www.wdc.com/products/internal-storage/wd-gold-enterprise-class-hard-... Think about it. If YOU had access to this data, would YOU erase it, if the storage only cost about $2000 per year? Jim Bell
