This explains the data handling practices on the Apple iOS app platform to let users know what data may be collected through the app and how it may be used.
The app computes how the purpose of a physical structure to support loads is served. Data keyed in by the user describes that structure and its purpose. The app collects no other data. The app has no ability to transmit data outside the device running the app other than through the facilities in Apple iTunes and then only when those facilities are invoked by the user. It prepares simple text files that record the input data and the results of the computation intended for these iTunes facilities.
