Privacy policy of packages/softwares installed in Debian

[npdflr <npdflr@zoho.com>]

Hello,

How can one check the privacy policy for the packages/softwares (which can be free or non-free) installed in Debian?

If one is downloading and installing a package from a website then he/she can check the privacy policy link on that website.

Example:

-- Skype (https://www.skype.com/en/get-skype/) which has privacy policy: https://privacy.microsoft.com/en-US/privacystatement

-- Go programming language (https://golang.org/) which has privacy policy: https://policies.google.com/privacy?hl=en

But if one is downloading a package (which may also install dependency packages) via terminal or synaptic package manager then how can one check the privacy policy of that package?

Thank you.
