Privacy Policy in UWP Store App ? Submission App Store Certification failed

I have a simple application to calculate the IP address, subnet mask, broadcast, range of IP addresses, the number of available IP addresses and CIDR.

App Policies: 10.5.1 Privacy Policy Notes To Developer Because your app accesses personal information, you need to supply a working link to a privacy policy in the “privacy url” field when you submit the app. See policy 10.5.1 for details about the requirements for a privacy policy.

But my app does not collect any user data, its work like simple calculator for Desktop or Mobile Devices.

Is it always necessary to have completed a URL link to your website PP, where you store your Privacy Policy, or you can use something universal like universal URL with Privacy Policy informations?
Maybe I fill or check something wrong the Submission form on Store Dev Acc after I requested this item to validation?
If the URL Privacy Policy required in Store Submission, it is necessary to put into application page Privacy Policy text Also, as was the case with WP 8.x applications.?

My application is FREE

Thank you

Sounds like the capabilities of the application may mean it gets categorised as accessing personal information. For example might think it gets the user's IP address which would be classed as personal information - you can always set up a github pages account then put your privacy policy there stating what happens with the IP address ie. nothing if that's the case and hopefully will help pass certification
