Will I need pemission from Amazon to do this?

Hello, I had a question and was hoping some of you could give me an answer.

So I wanted to create an android app where people can send recommendations about products/merchandise they like to friends/family/other about products you can typically find on amazon. They can share these links to anywhere, facebook, twitter email or whatever.

The links will be affiliate links and the app can replace these affiliate links with the persons, so they can make money for their recommendations.

It will not directly connect to amazon. Links and my own product titles (not descriptions) will be included in a SQL database.

Will I need permission from Amazon to do this? Could amazon potentially sue me?

If you have any questions or would like clarifications, please ask

Thanks in advance
