Group of myestimates applications use additional permissions on device just to bring more functionality to the user.

1. Storage permissions are used just to store and access documents/images created by the application in predefined folders. No other actions are done, no other locations are used, no other files are interacted by the program.
2. Camera permission is used to make photos directly in application during the work. It's not accessed by the application at other time without user interatction. Result of camera action is saved in predefined folders in external storage for easy user access even without application installed.
3. Internet permission is used by Google services like AdMob, FireBase, Billing. No more than required data for these services are transfered from the application. Also, application can work with their services to provide more functionality. At the current point only pomo-code service, that helps user to get their free time of usage of PRO services is defined. It's fully controlled by the developers of the myestimates application and requires user email and code for validation rules at first time of connecting. Then special token is used to avoid transfering email over the network for checking poromocode.
4. Collecting sensetive data. Application does store in database some information set by user like name, email, phone number to use it in business cases for each this data is required that is fully controlled by the user. Like ex. generating reports to the customer in PDF, generating mails, but this data or any other type of sensetive information that can be set in application is not shared with third party services
