Built by Onzira Labs, for people who want to understand their disk before changing it.

Every few months a Mac runs out of room, and the tools on hand are unhelpful in the same two ways. Either they show a number with no explanation — “System Data: 187 GB” — or they offer a big confident button that sweeps files away and hopes you did not need them.

We wanted the opposite: something that shows you exactly where the space went, explains what each thing actually is, and then does nothing at all until you decide. That principle drove some awkward choices. There is no one-click clean. There is no permanent delete. Nothing is called “junk” because that word usually means “we did not want to explain it”.

It also drove the privacy design. A storage tool sees your entire life: project names, client names, the document titled with something you would rather not read aloud. So VolumeLens has no network code. Not “we do not sell your data” — there is nowhere for it to go. You can verify that by turning off Wi-Fi and using every feature.

The storage engine is tested against synthetic filesystems built to break it: hard links, sparse files, symlink loops, filenames containing newlines and shell metacharacters, folders the operating system refuses to open. When a number cannot be known, the app says so rather than showing a confident zero.

We sell software for a fixed price and support it. There is no subscription, no account, no analytics dashboard tracking how you use it. If this company ever stops, the copy on your Mac keeps working, because nothing about it depends on us being here.
