About Tarnhelm
Tarnhelm is an open-source tool for cleaning up sharing links. Its GitHub repository describes it as "the magic to clean sharing links up," and its topics and store links indicate that it is an Android app. The project is licensed under GPL-3.0, and its source code is public.
The repository does not describe which parts of a link are removed, which apps are supported, or how links are processed. It also does not state what data the app handles, so privacy claims cannot be confirmed from the source alone. Project information is linked from the README at tarnhelm.project.ac.cn.
