The national Olympic association's general director, Michael Vesper, said he and German rowing officials held a meeting with Nadja Drygalla in which she "stressed credibly" that she "is committed to the values of the Olympic charter."
Drygalla was done competing at the games after the women's eight team failed to make Thursday's final.
Vesper says Drygalla said she would leave the Olympic village to avoid any "burden for the Olympic team." The chairman of the national rowing association, Siegfried Kaidel, said it would hold further talks with Drygalla after the Olympics on "the further course of action."
IOC spokesman Mark Adams said "I don't think it's an issue for us because she hasn't said or done anything related to the games."
Drygalla is a former police trainee. The state interior ministry in Mecklenburg-Western Pomerania, in northeastern Germany, said it came to its attention last year that her acquaintances included people who belong to the far-right scene.
A ministry statement said "intensive talks" were held with Drygalla which resulted in her resigning from the police force at the end of last September.
