Orielton Software gathers no user information from the MrsMcsMaths app.
The app maintains a history of recent results on each device. This can optionally include a user supplied name associated with a result. This information is stored within the app on the device. The app does not share this information with other apps or transmit it off the device. The history on a device can be erased at any time using the "Clear history" button under the "i" option on the main screen of the app.
