Chand, India’s reigning 100m national champion, won silver in both the 100m and the 200m at the 2018 Asian Games in Jakarta.
Despite slowly changing attitudes, gay sex remains taboo in India.
Chand said nobody had the right to judge her as an athlete because of her sexual orientation, which was a personal decision that should be respected.
«I have always believed that everyone should have the freedom to love. There is no greater emotion than love and it should not be denied,» she said.
She did not reveal her partner’s identity to save her from «undue attention».
Prominent Indian LGBT+ rights activist Harish Iyer, praised Chand’s courage, calling her a «beacon of hope».
Like South African Olympic athlete Caster Semenya, Chand has hyperandrogenism, a condition that naturally produces high testosterone levels.
She was previously barred from competing under International Association of Athletics Federations rules and subjected to abuse for being «unfeminine».
But Chand won an appeal at the Court of Arbitration for Sport (CAS) in 2015, paving the way for athletes with hyperandrogenism to compete in 100m and 200m races.
The decision allowed her to run in the 2018 Asian Games, where she twice made the podium.
However, the CAS earlier May rejected a similar appeal by Semenya against rules requiring middle distance female athletes with a high testosterone level to take medication to reduce it. Chand told local media the ruling made her «very sad».
