However, he has reiterated the club's position that he could leave if their asking price of €30million (£25.7m), cash only, is met.
Juventus were quick to make contact over Jovetic and are believed to have offered players plush cash for the Montenegrin, who has also been linked with Arsenal and Manchester United.
Prade, though, is adamant that Fiorentina are happy for Jovetic to remain at the club.
"Stevan is not on the market. There is a promise made by the president [Andrea Della Valle] to him, that he can leave him if we get an offer of €30million cash," he told Corriere dello Sport
"If not we'd gladly keep him. Jovetic has not said he wants to go away, it's a subject that will have to do with him and the president.
"There have not been offers, we only met the player's agent Ramadani. The president has not authorised me to speak with Juventus, it is up to the president to decide."
As well as Jovetic, his team-mate Adem Ljajic was linked with a move to his former club United.
But Prade says they are in talks with the young Serb over a new contract, and he added: "The Ljajic contract, we'll discuss with the agent in the coming days."
The Fiorentina chief did confirm that they are hoping to conclude a deal for Malaga winger Joaquin.
"There is a negotiation with Malaga, we'll talk this week with them to try to close the deal," he said.
