I take your privacy very seriously. I never collect any user data for sale or analytics. All data is kept on device and/or stored securely in a personal iCloud container, only shared with another Apple ID holder when that permission has been voluntarilly given (only in select apps).
When applications include advertisements, I use Kickstart Exchange (an advertising platform that does not sell your data for monetary gain - only for exposure to get the application advertised in other indie apps while we advertise their indie apps) by Hudson Heavy Industries Ltd. To see their privacy notice, click this link.
Some applications also include a feature called Kickstart Signal for in-app feature requests - create, vote, and comment on new features you care about. See Hudson Heavy Industries Ltd's privacy notice linked above as it also encompasses Kickstart Signal.
For any questions regarding this privacy policy, please contact the developer at digitalbudget.developer@gmail.com.
