Please create complete instructions for how to use your app. Emailing you for support is not as helpful as having instructions. The links to your blog do not work, unless this page is your blog. The English version of the app uses the word "Support" a lot, but this is not used correctly. When duplicate files have been found, I cannot tell, without instructions, what exactly has been found and what will be deleted if I click the "Clean" button. Add the option to "save the deleted files for recovery" to the preferences panel. I could give your app a better rating if I knew how to use it and what actions it is performing.
