LighterMac for macOS · last updated 20 September 2026
Buying LighterMac Pro gives you a personal, non-transferable licence to use it. One licence activates one Mac at a time. You can release it from that Mac and activate it on another whenever you like.
It is a one-time purchase. It does not renew, and there is nothing to cancel.
If LighterMac is not what you expected, email us within 14 days of buying and we will refund you. You do not have to give a reason.
LighterMac removes files you select. It sorts what it finds into three groups and will not remove anything in the “never touched” group under any circumstances.
Files LighterMac removes are moved to the Trash unless you explicitly choose to delete them permanently. Deleting permanently cannot be undone. Automatic rules, if you write any, only ever apply to items that rebuild themselves without any action from you.
LighterMac is careful, but it is a tool that removes files, and no tool is perfect. You are responsible for your own backups. If your Mac has no backup, LighterMac will tell you so.
LighterMac is provided as is. To the fullest extent the law allows, Cosmovex is not liable for loss of data, loss of profit, or any indirect or consequential loss arising from its use. Nothing here limits liability that cannot be limited by law. Our total liability will not exceed what you paid for the licence.
Do not resell, redistribute, or attempt to circumvent the licensing. Do not use LighterMac to remove files you are not entitled to remove.
We may end a licence obtained fraudulently or through a reversed payment. You can stop using LighterMac at any time by deleting it.
