## Career

At the 2018 US Open, von Deichmann made tennis history for her country by becoming the first Liechtensteiner to reach the main draw of singles of a Grand Slam, after winning three matches in the qualifying tournament. She defeated Priscilla Hon in the first qualifying round, Gail Brodsky in the second round and finally Martina Trevisan also in straight sets to reach the main draw.

Playing for Liechtenstein Fed Cup team, von Deichmann has a win–loss record of 23–14 as of March 2024.
She paired with Yvonne Meusburger for her WTA Tour debut at the 2014 Nürnberger Versicherungscup in doubles, losing in the first round.
Appearing as a lucky loser, Von Deichmann won her first completed WTA Tour match when she defeated eight seed Anna Karolina Schmiedlova in straight sets in the first round of the 2024 Prague Open, having previously triumphed in two matches in Lugano 2018 and Seoul 2023 when her opponents retired injured. She lost to Oksana Selekhmeteva in the round of 16.
At the 2024 Țiriac Foundation Trophy, she reached her first WTA 125 final defeating sixth seed Selena Janicijevic, Despina Papamichail, top seed María Lourdes Carlé, and wildcard Patricia Maria Țig. She lost in the final to Miriam Bulgaru.
