PackShift converts your .mrpack file entirely in your web browser using JavaScript. Your files are never uploaded to our servers, never stored, and never shared.
When you convert a modpack with mod downloading enabled, your browser downloads mod files directly from Modrinth's public Content Delivery Network (cdn.modrinth.com). These requests travel directly between your device and Modrinth.
We do not collect personal identifying information. Basic anonymous operational events (such as conversion success or errors) may be tracked only if analytics is enabled by the site operator, without any filenames or file contents.
