Trust and safety

Safe download guide

The safest download flow is boring: confirm the domain, open the source page, match your platform, and avoid anything that looks like an ad.

How to identify a trusted source

  • Check the domain before trusting a file.
  • Prefer project-controlled asset URLs or release pages.
  • Match the file name and platform before opening anything.
  • Avoid ad-style buttons and bundled download managers.
  • Do not install extra tools that a release page did not require.

External source policy

Release buttons open outside pages in a new tab with rel="nofollow noopener noreferrer". Button text stays explicit so users know the file is not coming from this site.
