Currently Ink Calendar collects no user data whatsoever. In fact Ink Calendar does not connect to the internet for any reason. No customer data is transmitted by JoeFinApps for any reason.
As of version 1.10 the user has the ability to use the app data sync function built into Windows 10. This data is stored, synced, and managed by Microsoft. JoeFinApps has not ability to access or recover this data in anyway.
If you have reason to believe the data in the app is being collected or viewed by 3rd party applications please let me know.
Thanks for using Ink Calendar.
