Last August, Google changed some Play Store rules to crack down on apps offering short-term loans often called “payday loans.” These financial transactions earned this name because they are used by consumers who are living paycheck to paycheck and need to borrow some cash to take them to the next payday. In the financial markets, companies usually pay lower interest rates for shorter-term debt. But because consumers who need these loans are considered high-risk (not exactly worthy of a AAA S&P rating) and are desperate, the companies funding these apps are demanding outrageous interest rates.
