What it sends us
Only on GitHub pages that show a SKILL.md or a skills folder, it sends the repository name and folder path to look the skill up. It doesn't run on other sites, doesn't send your browsing history, and has no analytics. To show Pro buttons, it checks whether Pro is on in this browser. Details are in the privacy policy.
