Early life
Daniela and twin sister Sandra (fellow pro-player) were born in Vienna, Austria.

Tennis career
Daniela played doubles with sister Sandra on the WTA Tour and the ITF Women's Circuit. The team dominated doubles tennis in Austria in the mid-2000s, becoming the country's No. 1 team in 2006. Daniela won a total of 23 titles on the ITF-level and reached one final on the WTA Tour-level. She reached the top 100 of the WTA doubles rankings in 2005. Daniela also represented Austria on the Fed Cup in 2005, when they defeated Switzerland.

Daniela played her final professional match on 14 December 2006 in Valašské Meziříčí, Czech Republic, partnering sister Sandra and losing in round one against Eva Hrdinová and Stanislava Hrozenská, 5–7, 2–6.

Death
In January 2007, both Klemenschits twins were diagnosed with a rare form of abdominal cancer, squamous cell carcinoma, forcing their retirement. Fellow tennis players rallied for Klemenschits and donated money to pay for the removal of several tumours and the expensive medical care required. Daniela died on 9 April 2008 in Salzburg, aged 25. Sandra, however, survived and returned to the doubles tour in July 2008.
