Systematic Cleaner

Tools

Every tool is free. Tools marked Windows exist only on Windows, because the part of the system they work on exists only there; on macOS and Linux they are hidden.

Home

Live processor and memory use, free space, a care score, and tiles for updates, startup apps, protection, vulnerabilities, threats and breaches. A tile turns yellow, orange or red when it needs you. This device shows the system, processor, memory, time since the last restart and, on laptops, battery health.

Free up space

  • System Cleaner: temporary files, caches, logs and leftovers in the system, browsers, 168 apps, games and AI tools, plus the Recycle Bin, broken shortcuts, unused PATH entries, database compaction and opt-in privacy traces. Search the results, choose item by item, and see a receipt of what was removed.
  • Disk Analyzer: every folder by size as a map, and space by file type.
  • App Space: each installed app's reported size next to the cache and log files the System Cleaner can review for it. Measuring removes nothing; Review files opens those files in the System Cleaner.
  • Large File Finder: the biggest files in a folder you choose, to move to the Recycle Bin or delete.
  • Downloads Review: old installers, archives and disk images in your Downloads folder, by age and size. Nothing is chosen for you, and the files you pick go to the Recycle Bin or Trash.
  • Duplicate Finder: identical files, compared by content. One copy of each is always kept, and files are checked again just before they are removed.
  • Empty Folder Cleaner: empty folders left behind by removed programs. System, profile and version-control folders are protected.
  • Storage History: snapshots of a folder's size over time, to compare and see what grew.
  • File Shredder: overwrites files with random data before deleting them, so they cannot be recovered.

Speed up

  • Performance Monitor: live processor, memory, disk and network charts, processor and graphics temperatures, memory used by each app and its processes, and disk health (S.M.A.R.T.). A process is ended only after it is checked to be the same one you chose.
  • Diagnostics: record a slowdown, then read a report of what happened and what to try. It is analysed on your computer and never uploaded.
  • Startup Manager: apps that start with your computer, ranked by their impact, to turn off or remove.
  • Services Manager: system services with guidance on which are safe to turn off, and a one-click recommended set.
  • Game Mode (Windows): pauses heavy services and background apps while you play, and restores everything when you stop.

Apps

  • Program Uninstaller: removes programs and cleans their leftover files. Shared components such as runtimes and drivers are kept out of batch removal and ask for confirmation.
  • Software Updater: finds updates through winget, Chocolatey, Scoop and npm on Windows, Homebrew on macOS, and apt, dnf or pacman on Linux. When an update cannot be applied, it shows the command to run yourself.
  • Driver Manager (Windows): installs newer drivers from Windows Update and removes old driver packages. Cleanup removes only driver packages that no device uses.
  • Debloater (Windows): removes preinstalled Windows and manufacturer apps.
  • Context Menu Cleaner (Windows): turns off or removes right-click menu entries added by installers.

Security and privacy

  • Malware Scanner: checks high-risk folders with YARA community rules, heuristics and persistence checks. Detections can be quarantined, restored or allowed.
  • Threat Monitor: checks your network connections and DNS against free public threat lists, and alerts you on a match.
  • Vulnerabilities: matches the versions of common installed apps, and macOS, against the public NIST vulnerability database, and shows the version that fixes each flaw.
  • Breach Monitor: tells you when an email address you add appears in a known data breach.
  • Firewall Audit (Windows): finds inbound firewall rules that are too broad, point to missing programs, or allow unsigned files.
  • Privacy Shield: turns off telemetry, advertising and tracking settings. Every change is recorded and can be undone. On Windows, App access shows which apps Windows recorded using the camera, microphone and location, with links to the matching Windows settings.
  • Network Cleanup: clears the DNS cache and removes old Wi-Fi profiles and network history.

Repair

  • Registry & System (Windows): finds broken registry entries and weak security settings. A backup is saved before anything is changed.
  • Disk Maintenance: runs TRIM on solid-state drives.
  • Windows Repair (Windows): runs SFC, DISM and CHKDSK to check and repair system files and disks.

Routine and records

  • Schedules: routines that clean, scan and update on their own, and wait for idle time, mains power and a time window you set.
  • Activity: every scan and cleanup, with what was found, removed and skipped.
  • Recovery Centre: recorded setting changes and registry backups, restored only when the current state allows it safely.
