The 26-year-old winger joins the Reds to strengthen their attacking options ahead of the 2018-19 FA Women's Super League season.
Daniels, who can also play as a striker, came through the youth set-up at Oud-Heverlee Leuven before spells with Lierse, FC Twente and Anderlecht.
"This is a great move for me and I am really looking forward to working alongside Neil [Redfearn] and the players," she said.
"The squad here has big potential and I am really confident that we will have a successful season this year.
"Once I heard of the interest from Liverpool Ladies, there was only one club that I wanted to sign for and I cannot wait to get started."
Ladies manager Redfearn said: "This is another great signing for the club.
"Yana will give us more options in the final third and I am really confident that she will become a real fans' favourite.
"Yana is a hard-working winger whose versatility to also play up front gives us far more attacking options as we look to add more goals to the team."
