Be careful it is not only 0,99 euros
I used Sub Edit pdf just for one time for 0,99 (the 29 of June 2024) and today I noticed they charged me 39 euros as a monthly payment (the 2 of July 2024) for which I did not give any order through their site. This is a fraud and I am now forced to cancel my card to prevent a new charge in the future.
