Social Media apps + Amazon Cookies?

Nowadays most of the social media traffic is mobile and most apps i know fb/tumblr/pinterest/ig have they "own" browser. Now wondering if someone visit my site and click on amazon link but not purchase product right away and decide to purchase it let say next day so there is still 24 hrs cookies but will the next day open his chrome browser will be there the cookies or they are on the app browser?

Short , does app browser transfer/share same cookies as chrome/default phone browser?

Everything is fine. The cookie is not stored in the browser.

well it they are not stored = lose potential sales that is my concern here

Oh sorry. It seems I misunderstood the question. It looks like each application saves cookies separately. And not in every application they are included by default. Yes, this is a problem.
