Kane is in the peak years of his career, but speculation this week mounted that he may soon be back at Tottenham.
The North London club's chairman Daniel Levy stated they had a buy back clause in the deal that took Kane to Bayern this summer.
Freund told DAZN: “We won't say anything about that [the buy-back clause]. We never reveal anything about contract details.
“Harry is here, has left England for the first time with conviction. We have a four-year contract with him. We are very, very happy and are planning long-term with him at Bayern.
“He will shape this team and an era here. I'm convinced of that. He feels very comfortable and has big goals with Bayern in the coming years."
