Vallt Cleaner is a disk cleanup application for Windows 10 and 11.
Most cleaners run down a list of known temporary folders and stop there. Vallt reads the structure of the drive instead, finding duplicates, forgotten installers, orphaned game caches and leftovers that traditional tools walk past. It recovers space they never reach. When it isn't certain about a file, it leaves it alone rather than suggesting it.
Cleaning is fully reversible. Files move into a local quarantine you can undo with one click, and disk space is only freed when you deliberately purge, confirming by typing DELETE. Nothing is removed without an explicit second step.
Everything runs on the machine. There is no account, no cloud and no telemetry, and nothing about your files is ever collected or transmitted.
The free version scans and reports where your space went. A one-time payment unlocks cleaning, with no subscription and no renewal.
assertpy Vallt CleanerVallt Cleaner's answer:
Three things. Vallt Cleaner finds more junk than traditional cleaners, because it reads the structure of the drive rather than running down a fixed list of temp folders. It never puts a file at risk doing it: cleaning moves files to a local quarantine you can undo with one click, and space is only freed when you deliberately purge. And it runs entirely on your machine, with no account, no cloud and no telemetry, in a category where data collection has been the norm. No other cleaner combines all three.
Vallt Cleaner's answer:
Traditional cleaners delete permanently, and some are known for wiping folders users actually cared about. Vallt Cleaner cannot cause that outcome: nothing is removed without an explicit second confirmation. Where competitors have shipped telemetry, ads and bundled software, Vallt Cleaner collects nothing at all, and nothing about your files ever leaves the machine. It is also a one-time payment in a category that has largely moved to subscriptions. It makes no claims about speeding up your PC, and it does no registry cleaning.
Vallt Cleaner's answer:
Windows 10 and 11 users who are running out of disk space and are afraid of deleting the wrong thing. Gamers whose libraries and shader caches consume hundreds of gigabytes, content creators with large project files, and anyone on a smaller SSD where every gigabyte matters. It also fits privacy-conscious users who avoid traditional cleaners specifically because of their reputation for telemetry and bundled software.
Vallt Cleaner's answer:
It started from a recurring problem: a drive fills up, you go looking for things to delete, and then you freeze, because half the folders are unidentifiable and the other half look risky. Existing cleaners made that worse by deleting permanently, and several of them turned out to be collecting data while doing it. Vallt Cleaner was built on the opposite premise: cleaning should be reversible and entirely local, so you can be aggressive about recovering space without gambling on it and without trusting anyone with your data.
Vallt Cleaner's answer:
Python 3.13, PySide6 (Qt) for the desktop interface, and SQLite for the local file index. Windows installer built with Inno Setup. Licensing uses Ed25519 signatures validated locally.
