Run vLHCathome only on authorized computers

Run vLHCathome only on computers that you own, or for which you have obtained the owner's permission. Some companies and schools have policies that prohibit using their computers for projects such as vLHCathome.

How vLHCathome will use your computer

When you run vLHCathome on your computer, it will use part of the computer's CPU power, disk space, and network bandwidth. You can control how much of your resources are used by vLHCathome, and when it uses them.

The work done by your computer contributes to the goals of vLHCathome, as described on its web site. The application programs may change from time to time.

Privacy policy

Your account on vLHCathome is identified by a name that you choose. This name may be shown on the vLHCathome web site, along with a summary of the work your computer has done for vLHCathome. If you want to be anonymous, choose a name that doesn't reveal your identity.

If you participate in vLHCathome, information about your computer (such as its processor type, amount of memory, etc.) will be recorded by vLHCathome and used to decide what type of work to assign to your computer. This information will also be shown on vLHCathome's web site. Nothing that reveals your computer's location (e.g. its domain name or network address) will be shown.

To participate in vLHCathome, you must give an address where you receive email. This address will not be shown on the vLHCathome web site or shared with organizations. vLHCathome may send you periodic newsletters; however, you can opt out at any time.

Private messages sent on the vLHCathome web site are visible only to the sender and recipient. vLHCathome does not examine or police the content of private messages. If you receive unwanted private messages from another vLHCathome user, you may add them to your message filter. This will prevent you from seeing any public or private messages from that user.

If you use our web site forums you must follow the posting guidelines. Messages posted to the vLHCathome forums are visible to everyone, including non-members. By posting to the forums, you are granting irrevocable license for anyone to view and copy your posts.

Is it safe to run vLHCathome?

Any time you download a program through the Internet you are taking a chance: the program might have dangerous errors, or the download server might have been hacked. vLHCathome has made efforts to minimize these risks. We have tested our applications carefully. Our servers are behind a firewall and are configured for high security. To ensure the integrity of program downloads, all executable files are digitally signed on a secure computer not connected to the Internet.

The applications run by vLHCathome may cause some computers to overheat. If this happens, stop running vLHCathome or use a utility program that limits CPU usage.

vLHCathome was developed by CERN. BOINC was developed at the University of California.


vLHCathome and CERN assume no liability for damage to your computer, loss of data, or any other event or condition that may occur as a result of participating in vLHCathome.

Other BOINC projects

Other projects use the same platform, BOINC, as vLHCathome. You may want to consider participating in one or more of these projects. By doing so, your computer will do useful work even when vLHCathome has no work available for it.

These other projects are not associated with vLHCathome, and we cannot vouch for their security practices or the nature of their research. Join them at your own risk.
