SCal doesn't collect any personal information from the user, nor reads any personal information from the user device. SCal is a calculator that does computation on the given user input and displays the result.
By default when application is closed all the user input data and their results are discarded by the App (SCal), that is they are neither saved in the user device nor transmitted to any other device or network.
Users have a choice to save their input data and results to a file by clicking on the "File Folder" Button. Upon trying to save a Dialog Message is prompted to the user mentioning "Allow Scal to access photos,media, and files on your device?" With choices of "Deny or Allow". When User selects Deny , SCal does NOT save any data in the user device, if the user selects "Allow" then user data along with their results are saved in the User Device under Download Directory.
Data that are saved in the user device ARE NEVER read by SCal, and SCal doesn't read any of the user device files. SCal doesn't send any data to third-parties.
SCal comes in two flavors, paid SCal app doesn't show any ads, whereas Scal(Free) shows ads which are provided by Google AdMob for Android Systems and StartApp for iOS Systems.
