All of the app data is stored on your local device and, in the case of Clever Contacts or P&F Charts, in your own personal Apple iCloud account. It is not shared with the developer or available to anyone else. Only those that have access to your devices have access to your data.
See below for additional information regarding data storage for particular apps.

- app wide data such as the version number and your chosen chart colour palette
- the names of all your watchlists and which stocks are within them
- the details of all your stocks including the charting parameters for that stock and which indicator to show
- the prices for each stock
All of the above (except for the price data which is always stored on the local device) can be stored on either your personal iCloud account or your local device. The default option is to use your iCloud account unless you are not logged into iCloud when the app starts.
