This metasearch engine ensures that no personal data is stored or shared, making it a compelling choice for users concerned about online anonymity. The service operates without advertisements, enhancing the user experience by providing clean and direct search results.

To utilize MetaGer, users need to create an anonymous paid account known as MetaGer Key, which operates on a pay-as-you-go basis.
