The breach notice recommends that users review their accounts and avoid clicking links from suspicious sources. Users also will be required to change their account password. According to Under Armour, the app does not collect Social Security or driver's license numbers from users, so that information was not exposed. Credit card data was not breached either, the company said, because payment information is collected and processed separately.
The free app, MyFitnessPal, which has a paid option, lets users track the foods they eat over time, with features to log calories and different types of nutrients.
