I'm not storing any data other than a day of the year and wether a pill was taken. It has Google Analytics and a crash reporting tool in it, and I'm not sure how those play into the whole thing.
I'm not familiar with iOS but is the crash reporting not part of the OS/store? If so that is there problem.
