link/lead tracking plugin for WordPress 4.5.3.

Hello,
I need a link/lead tracking plugin for WordPress 4.5.3.

Does your product meet my requirements below?

1) I have a site that does not have eCommerce. I have customer’s signing up for a service (simple form) and we bill monthly after the service is provided.
2) I just want to be able to generate custom links (unlimited time frame) for each of my referral partners. These can be marketed on websites, through email, twitter, etc. and should stay with the visitor (who clicked the link) throughout their time on my website. I would like the form to recognize the link and auto populate the referrer’s name or unique identification into a referred by field in the form (could recognize the link in a database and pull the corresponding code/name from database to populate the form field.)
3) I need to be able to generate unique links for each partner that I sign up. I am ok with manually being able to generate these links/codes, but could be open to an auto-referral partner link program in the future on my site.
4) What forms, auto-email do you work best with?
5) Can I store all information on my site or in my site database because some of the information that customers input in the form will be sensitive.

Will your product work for me?

Thanks.
