Remove leftover files, registry traces and browsing history from your system.
Deep Windows cleaner for traces, registry leftovers and free-space sanitization.
Our review
PrivaZer goes further than generic cleaners with granular scan profiles and a clear report before you delete anything. The free version is fully usable for home users; the interface is dense but honest about what it finds.
Pros
Cons
Open-source system cleaner with shred support and app-specific cleaners.
Our review
BleachBit is the trustworthy alternative when you want no telemetry and reproducible cleaners. It is less flashy than commercial suites but excellent for developers and Linux desktops.
Pros
Cons
Popular all-in-one cleaner with startup manager and duplicate finder.
Our review
CCleaner is still widely known and easy for casual cleanup. After past bundling incidents, stick to the official installer, decline extras, and prefer BleachBit or PrivaZer if you want maximum transparency.
Pros
Cons
Overwrite files and free space so recovery tools cannot bring data back.
Schedule secure overwrites of files, folders and free disk space.
Our review
Eraser is the classic choice when you need provable deletion on Windows — for old drives, donated PCs or compliance-minded home offices. Pair it with full-disk encryption for defense in depth.
Pros
Cons
Browse with less tracking, fingerprinting and third-party cookies.
Firefox-based browser that routes traffic through the Tor network.
Our review
Tor Browser is essential when you need anonymity against network observers — not just ad blockers. It is slower and some sites block Tor exits; use it for sensitive research, not everyday shopping.
Pros
Cons
Scan Android apps for embedded trackers and permission overreach.
Our review
Exodus Privacy shines a light on SDK trackers inside APKs — invaluable before you install another flashlight app. The website lets you search packages; the Android app audits installed software.
Pros
Cons
Privacy-oriented search and browser extensions that block third-party trackers.
Our review
DuckDuckGo is an easy first step: change search engine, add the extension, enable email protection if you want. It is not as strong as Tor for anonymity but excellent for reducing everyday tracking.
Pros
Cons
Encrypt disks, containers and sensitive files against theft or loss.
Create encrypted containers or encrypt entire partitions and drives.
Our review
VeraCrypt is the successor to TrueCrypt and still the gold standard for local encryption. Use hidden volumes only if you understand the threat model; for most users a strong password plus a regular encrypted volume is enough.
Pros
Cons
Offline password manager with local encrypted database and TOTP support.
Our review
KeePassXC keeps credentials on your machine — ideal if you distrust cloud vaults. Pair with a synced file over your own Nextcloud or a USB backup; browser integration is solid on desktop.
Pros
Cons
Hide traffic from ISPs, block ads at the DNS level and monitor connections.
VPN from the Proton privacy suite with Swiss jurisdiction and open clients.
Our review
Proton VPN is a credible no-logs VPN with audited infrastructure and a usable free tier. VPNs do not make you anonymous alone — combine with HTTPS, Tor when needed, and realistic expectations about DNS leaks.
Pros
Cons
Network-wide DNS sinkhole that blocks ads and trackers for every device at home.
Our review
Pi-hole is the set-and-forget layer for household privacy — once your router points to it, phones and smart TVs stop phoning home to ad domains. Run on a Raspberry Pi or any always-on Linux box.
Pros
Cons
End-to-end encrypted chat and calls without selling your metadata.
End-to-end encrypted messenger with voice/video calls and minimal metadata.
Our review
Signal remains the benchmark for private messaging: open protocol, nonprofit funding, and sealed sender improvements. You still need phone verification — for highest anonymity consider secondary numbers.
Pros
Cons
