Does SmartyPig transfer ACH or EFT funds into a mutual funds sweeps account or any other money making account at any time? I read on line that Bank of America will take a customer's Keep the Change savings and transfer the money into the sweeps account at night and re-transfer it back to your own savings in the morning. The catch is that they don't bother to tell customers this when they apply for a savings account and I am curious about SmartyPig doing something like this.
