PruPru Digital Services develops PruPru.exe (the "App") and the prupru.org website (the "Site"). Contact: efojunior25@gmail.com.
By downloading, installing or running the App, or by using the Site, you agree to these Terms of Use and to our Privacy Policy. If you don't agree, don't use the App or the Site.
The App and the Site are intended for people with full legal capacity (18 or older) or, in the case of minors, with the authorization and supervision of a parent or legal guardian. We do not knowingly collect data from children under 13 — see the Privacy Policy for more.
PruPru.exe is a free diagnostics, optimization and security panel for Windows, distributed as a single executable file, no installer, no sign-up required. It bundles 11 tools and extra features, including:
Some tools require Windows administrator privileges (UAC) to work, since they change system settings (power plan, DNS, services, registry, firewall rules). The App always asks for your explicit confirmation before applying changes, and creates a Windows restore point before running the System Optimizer.
By using any tool that requires administrative privileges, you expressly authorize the App to request that elevation from Windows (UAC) and to perform the actions described on that specific tool's confirmation screen. The App never requests privilege elevation silently or without a prior confirmation screen.
We grant you a free, personal, non-exclusive, revocable license to download and use the App for personal or commercial purposes. The source code is public on GitHub (github.com/efojunior25/prupru-app); this doesn't give you the right to sell the App as your own, remove PruPru Digital Services' credit, or distribute modified versions pretending to be the official app.
The App and the Site are provided "as is", without warranties of any kind, express or implied. We don't guarantee the App is error-free, that it will fix every issue on your PC, or that it's compatible with every hardware/software configuration.
Tools like System Optimizer, Network Turbo, Startup Manager, Game Focus and Streaming Mode change real Windows settings (registry, services, firewall, power plan). While they're documented and reversible, and the Optimizer creates a restore point before acting, there's inherent risk in any system change — including, in rare cases, operating system instability. We strongly recommend keeping an up-to-date backup of your important data before using these tools. You use these tools at your own risk.
To the fullest extent permitted by applicable law, PruPru Digital Services' liability for any damages arising from use of the App or the Site is limited to cases of proven willful misconduct or gross negligence on our part. We do not exclude liability for willful misconduct or gross negligence, as prohibited by law. Outside of those cases, we are not liable for indirect or incidental damages, lost profits, or data loss resulting from the normal, informed use of the tools described in Section 8.
The App automatically checks for new versions on public GitHub releases and asks before installing any update. You can decline an update at any time.
PruPru.exe is free and has no paid version. The Site offers voluntary ways to support development (Pix and PayPal). Donations are voluntary, create no additional contractual obligation on our part — including no guarantee of influence over the feature roadmap — and are non-refundable except where required by law.
The Site may display ads via Google AdSense. See the Privacy Policy for details on cookies and data used for ad personalization.
The App and the Site rely on third-party services to work fully — GitHub (distribution and updates), Cloudflare (Site hosting), Google AdSense (ads), Brazil's Central Bank/Pix and PayPal (donations). We are not responsible for the availability, privacy practices, or failures of these third-party services; using them is governed by each company's own terms and policies.
We may discontinue, modify, or shut down the App or the Site at any time, without prior notice, without any right to compensation. Since the App doesn't depend on servers to work (except the optional update check), already-downloaded copies keep working normally even if the project is discontinued.
We may update these Terms periodically. The date at the top of this page shows the latest version. Continued use of the App or the Site after a change means you accept the new terms.
These Terms are governed by the laws of Brazil, without prejudice to any rights your country of residence's consumer protection laws may grant you. Disputes will be resolved in the courts of PruPru Digital Services' domicile in Brazil, except where consumer-protection venue rules require otherwise.
If any clause of these Terms is found invalid or unenforceable by a competent court, the remaining clauses stay in full effect. Failure to enforce any clause does not waive the right to enforce it later.
