Important note

CCleaner v6.29 is a cleaning and maintenance tool, so it should be used with discretion. Before deleting files, cleaning traces, reviewing the registry, or deleting application data, it is recommended to carefully verify which items will be deleted.

Aggressive cleaning without backup is not recommended, especially on work computers, accounting systems, design workstations, computers with licensed programs, or computers with important information. Some cleanups may close sessions, delete cookies, remove useful caches, or affect saved settings.

In Windows, registry cleaning should be used with special care. For added security, it is recommended to create a restore point and avoid deleting entries that are not fully understood.

Differences between alternative license and original license

This information is included so that the customer clearly knows what type of license they are acquiring and what functions they can expect depending on the chosen option.

Alternative license: is a non-original license, single payment and without monthly or annual subscriptions. It allows you to use the program functionally to delete temporary files, clear cache, review traces, free up space, manage applications, optimize basic elements, and keep the system tidier from the computer where it is installed. It does not include official updates, full online services, official CCleaner support, downloads from a personal account, official account benefits, formal commercial licensing, or full linkage to the manufacturer's personal or business accounts. Linking accounts, manually updating, modifying program files, or attempting to activate online services may affect activation and require additional technical assistance at a cost.

Original license: is the official manufacturer's option. It includes access to full features according to the contracted plan, official account when applicable, available updates, official support, current benefits, and services authorized by the manufacturer. Its cost is usually higher and it can operate under an annual license, subscription, individual plan, multi-device plan, enterprise license, renewal, or modality defined by CCleaner / Piriform.

For business, corporate, governmental, technical, academic, or institutional use, Luctecno recommends original licenses, as they are the appropriate option to comply with best practices, formal support, official compatibility, security, and higher professional needs.

Note: These licenses are linked to the computer where they are installed and are not transferable.
