Other components
Native dependencies include Mixpanel Swift and Mixpanel Swift Common under Apache License 2.0, and JSON Logic Swift under MIT. The website uses React, vinext, Cloudflare tooling, Motion, Lucide and locally hosted Nunito Sans. Exact versions and complete notices must accompany the corresponding release; this overview is not a replacement for those notices.
The licensed app uses online Lemon Squeezy activation. A lifetime license covers two Macs and includes lifetime updates, with no subscription. A paid entitlement does not remove rights granted under an applicable open-source license.
Using file-management software
Review your selections and keep backups. Scans can be incomplete because of exclusions or permissions. Permanently deleting an item may disrupt an app or require re-downloads. Deletion cannot be undone and does not guarantee that all estimated space is immediately reclaimed. Verified SSD relocation preserves a source backup, and unresolved relocation records require explicit recovery. These practical cautions do not waive mandatory consumer rights.
