Does CCleaner sell your data? No, it doesn‘t.

With over 2 billion downloads worldwide, CCleaner is one of the most popular PC optimization tools. It provides an easy way to clean up junk files, browsing traces, and system clutter on Windows devices.

But does using CCleaner mean compromising on your privacy? Can it collect and sell your personal data to advertisers and third parties?

The short answer is no. According to all available information, CCleaner does not sell any private user data.

But as with all free software, CCleaner isn‘t completely hands-off when it comes to gathering user information. This comprehensive, 2600+ word guide will shed light on what data CCleaner collects, how it uses and shares that data, its privacy practices, past security issues, and whether CCleaner is ultimately worth using or not.

What User Data Does CCleaner Collect?

CCleaner needs to collect some diagnostic and usage data to function properly and improve the software over time. But Piriform, its developer, states that CCleaner does not collect any personally identifiable information.

As per their privacy policy, here are the key data points gathered by CCleaner:

• Installation and usage data: When you first install CCleaner, it records information like your IP address, CCleaner version, language setting, device type, operating system, etc. This helps deliver the right software experience.

  Aggregated usage data like feature adoption helps prioritize improvements. As per a Piriform statement in 2017, about 20% of CCleaner‘s user base opts into sending usage data.

• Crash and error reporting: When CCleaner runs into issues, it generates crash logs and diagnostic reports. These are sent back to Piriform to fix bugs and improve stability.

• Performance analytics: CCleaner may share anonymous usage statistics and performance metrics with third-party analytics tools like Google Analytics and AppNexus. This provides an aggregated view of how the software performs globally.

• Basic system data: CCleaner collects standard details about your operating system, browser versions, and hardware configuration. This is required for compatibility and troubleshooting purposes.

Importantly, Piriform insists no personal user data is collected without explicit consent:

"We do not process any personal data in CCleaner without the knowledge and consent of the user."

So information like your passwords, browsing history, personal files, etc. are not accessed or sent back to Piriform servers.

Now that raises the next big question…

What Does CCleaner‘s Privacy Policy Say?

CCleaner‘s privacy policy provides more transparency into its data collection practices. Let‘s take a look at some key aspects:

• IP addresses are collected only for downloading products, billing, authorization, and fraud prevention by external payment processors. Piriform does not independently store or track IP addresses.

• Crash reports and diagnostic data may be shared with third-party analytics services to improve CCleaner. However, this data is aggregated and anonymized before sharing.

• Browser cookies are used only if you expressly consent to enhance CCleaner‘s functionality. You can revoke this consent anytime.

• Users can opt-out of sharing usage data completely from the Settings panel, albeit with limited functionality. Diagnostics data cannot be disabled.

• Personally identifiable data like names, addresses, and payment information is never collected or retained (unless a user contacts support).

Piriform also states it does not sell such private information to any third parties.

So in summary, CCleaner‘s privacy policy reassures users that it does not misuse, sell or share personal data. Some basic usage telemetry and diagnostics are still collected, which is fairly standard for free software.

Does CCleaner Sell Your Data? What the Evidence Says

There is no evidence of CCleaner selling private user data despite concerns raised over the years.

Piriform has clearly asserted that CCleaner does not "sell or share information that directly identifies you". There are also no documented cases of CCleaner data misuse or breach.

In fact, CCleaner‘s business model relies on converting free users to premium paid licenses and revenues from its browser toolbar. It does not need to monetize user data illegally.

Of course, Piriform‘s privacy assurances may not be enough for some cautious users. But so far there‘s no reason to believe CCleaner is engaged in selling user data.

For additional context, here are some key events in CCleaner‘s history:

• 2017 breach: Hackers managed to inject malware into CCleaner downloads, potentially impacting 2.27 million users. However, Piriform asserted no user data was compromised.

• Ownership changes: Anti-virus firm Avast acquired CCleaner in 2017. Again, there were no resultant privacy policy changes.

• GDPR compliance: CCleaner updated its privacy terms in 2018 to comply with the EU‘s GDPR laws and continues providing user data controls.

Once more, there are no reports of CCleaner selling user data before, during or after the above events. Of course, skepticism is valid for any free software. But based on current evidence, CCleaner checks out on the privacy front.

Is CCleaner Ultimately Worth Using in 2024?

Given the misgivings some privacy-conscious folks have about CCleaner, is it ultimately worth having on your Windows PC in 2024?

In my opinion as a long-time tech writer and CCleaner user, the benefits still outweigh the small privacy risks for most users.

Here‘s a quick rundown of pros and cons:

The case for using CCleaner

• Keeps PCs running smoothly by cleaning unnecessary junk files and clutter.

• Provides visibility into trackers and opaque system files. Saves manual effort.

• Lightweight app with no upfront costs. Easy to install and configure.

• No proof of selling user data despite past security concerns.

• Robust privacy controls to limit data collection. Can opt-out of sharing usage statistics.

The case against CCleaner

• Questionable need for system "cleaning" tools in modern Windows versions.

• Past malware injection attack does raise some red flags.

• Still gathers some usage statistics and crash data with unclearthird-party sharing.

• Extra software with potential vulnerabilities is risky for security-conscious users.

• Advanced power users and enterprises may not require CCleaner‘s basic optimizations.

So in summary, CCleaner is safe and beneficial for many users. But those highly concerned about privacy or security may want to avoid it, or at least selectively opt-out of data sharing.

Final Verdict: Look at Alternatives But Don‘t Worry Too Much

Based on current information and historical evidence, CCleaner does not sell private user data to third parties. The risks are minimal for average users.

But it‘s wise to be somewhat cautious when installing any free utility tool. While CCleaner asks for the bare minimum user data it needs to function, alternatives like BleachBit and PrivaZer offer a more hands-off approach.

Of course, don‘t believe unsubstantiated claims about CCleaner selling your browsing history or personal data. But do consider your personal privacy priorities and comfort levels before installing it.

For most users though, CCleaner is safe to use and provides useful functionality to streamline PCs. Just make sure to disable any data collection you are uncomfortable with in Settings.

At the end of the day, don‘t let unverified CCleaner privacy concerns keep you from trying a useful tool. But it never hurts being a bit careful when choosing third-party software for your computer or mobile devices.
