Qulok is free desktop software for Windows, licensed to you for personal and commercial use on computers you own or control. You may not redistribute modified copies under the Qulok name.
Qulok changes window state and a few Windows settings on your behalf and restores them afterwards. It is provided as is. To the extent the law allows, we are not liable for any loss arising from its use, including a setting that was not restored. If something is not restored, relaunching Qulok runs the restore again, and every setting it touches can also be changed back by hand in Windows Settings.
