By downloading and using Altushka Builder, you agree to our Terms of Service and Privacy Policy. You'll also confirm this in the app the first time you open it.
macOS: the build is signed with an Apple-issued Developer ID certificate and notarized by Apple, so it avoids the standard "unidentified developer" warning. Windows: the build ships unsigned for now, so SmartScreen may warn when you run the installer — click "More info" then "Run anyway". It installs for your user only, so there is no admin prompt.
Parts are fetched online and cached locally, so an internet connection is needed the first time you use a part. After that, cached parts keep working.
No updater to babysit: the app shows a banner when a new version is out, and you get the new build from itch.io.
