Notes
- The first Premier 5 event of the year has switched back and forth between the Dubai Tennis Championships and the Qatar Ladies Open since 2009 until 2024. Dubai was classified as a Premier 5 event from 2009 to 2011 before being succeeded by Doha for the 2012–2014 period. In 2015, Dubai regained its Premier 5 status while Doha was demoted to Premier status. The Premier 5 tournaments were reclassified as WTA 1000 tournaments in 2021.
- During the season, she did not play in the main draw of any tour-level tournaments. However, she played in the Billie Jean King Cup, which is not counted as a played tournament but matches are counted.
