Using tweets for Alexa skill


I would like to understand the twitter policy more. I’ve been developing a free to install Alexa skill that consumes a twitter account’s tweets in the last 24 hours and read it out loud. I have clearly stated in the Alexa skill documentation that this particular twitter account is the only data source I use. When a user is using it the skill on the daily basis, no credits would be mentioned anymore (due to UX reason of course). The twitter account in question is a public account. Does this Alexa skill violate any of the current rule or policy?
