PruPru.exe is distributed with no installer, no sign-up and no hidden data collection. This page exists so you can check exactly what it does and how it updates itself — without having to just take our word for it.

Open source

PruPru.exe's source code is public on GitHub. Anyone can read the scripts that make up each of the 11 tools before downloading the executable.

PruPru for Linux and macOS

Besides the Windows .exe, PruPru is also available as PruPru.sh (Linux) and PruPru.command (macOS), with the same 17 tools, open source and no install required. The macOS version is still beta — carefully reviewed, but not yet tested on real Mac hardware, since we don't have a macOS machine available to validate it before release. The Linux version was tested end-to-end before release. Get both from the Downloads page.

How auto-update works

PruPru.exe periodically checks the repository's public releases on GitHub and downloads the latest version when one is available. No data from your PC is sent during this process — the check is just "is there a new version?".

File integrity

SHA-256 hash of the current version of PruPru.exe, so you can verify that the downloaded file hasn't been tampered with:

What PruPru.exe accesses on your PC

The app reads local hardware information (disk usage, memory, processes, installed drivers) to generate diagnostics — all of it stays on your computer. Nothing is sent to PruPru's servers during normal use, except for the update check (which only asks whether there's a new version on GitHub, without sending any data from your PC) and the report submission if you choose to use the Share Report tool on this site, which does store the content you manually paste in for up to 30 days.

Frequently asked questions

How do I check that the downloaded file's SHA-256 matches the published one?

On Windows, open PowerShell in the folder where you saved the file and run Get-FileHash PruPru.exe -Algorithm SHA256. Compare the result with the hash published on this page.

Can I disable auto-update?

Yes, the option is in the app's own settings. With auto-update disabled, you can still download new versions manually from the Downloads page.

Why trust a closed app if the code is open?

The distributed executable is compiled from the same code published on GitHub. Anyone with technical knowledge can compile from the source code and compare it, instead of relying solely on the pre-built binary.
