K-win is designed with safety as a core requirement:

• ✅ Automatic Restore Points before major operations
• ✅ Backup-first changes for registry operations
• ✅ Undo support for recent operations
• ✅ Preview dialog before applying changes
• ✅ No risky “registry cleaner” behavior
• ✅ Open-source transparency
• ✅ No telemetry from the app itself (works offline)

For full technical details, see SAFETY.md.
