I do projects like this for free and have nothing out of it. It is enough for me to help others in everyday life and to learn something for myself. I have complied with all data protection guidelines that apply in Germany. Yes, the website is currently only available in German, but I'm changing the days. But I think it's so intuitive that you understand it right away. I have assembled other open source projects (MIT), as can be read in the license. It is not perfect and certainly there are better ones, but for me and my purposes it is perfect and maybe there are some where it also helps to save tokens.
