Pricing

$39 a year. Or $89, forever.

Annual keeps new versions coming and the app is yours to keep even if you cancel; Lifetime is one payment for every version we ever ship. 3 Macs per license, no account.

Buy it like a tool, not a service.

Pay yearly, or pay once and get every version we ship. Either way the app is yours, and it keeps working even if you stop.

Free to download.

Install Plumby and see your own numbers: what is filling your disk, what is using your memory, what is inside “System Data”. Buy when you want it cleared.

No account, and nothing expires. 14 days to change your mind.
