When Beyoncé’s album “Lemonade” was released late Saturday night, it was available only on Tidal, a big win for that subscription streaming service, in which Beyoncé is a part owner.

But Tidal’s period of exclusivity appears to be quite short — just 24 hours, as the album is expected to be released for sale on iTunes at midnight on Sunday, according to two people briefed on the plans for the release, who, following the usual ironclad rules of secrecy surrounding Beyoncé’s projects, were not authorized to discuss them. Apple declined to comment.

A spokeswoman for Beyoncé did not immediately respond to a request for comment.

Late Sunday afternoon, Tidal announced that in addition to its streaming version of “Lemonade,” it would be selling a version for download at $17.99. A Tidal spokesman said that the service would have the exclusive streaming version “in perpetuity.” Amazon also confirmed that it would soon begin selling both digital and physical versions of the album.
