Stoke have been linked with Smithies with the club understood to have watched the keeper on several occasions this term.
Huddersfield are keen to keep hold of the talented 19-year-old and the player's advisor, Tony Coton, insists Smithies is happy to continue learning his trade at the League One outfit.
"Alex is very happy at Huddersfield," Coton told skysports.com. "He is a local lad and he is learning his trade.
"I think the link with Stoke came about after I was seen at a Huddersfield match with [Stoke assistant manager] Peter Reid, but I think people were jumping to conclusions.
"Peter is a good friend of mine and as we were going to the same match we decided to go together."
"I have no doubt Alex will play at the highest level at some point in his career as he is a top talent, but all he is focusing on at the minute is playing for Huddersfield and continuing his education in the game."
