Read our rules and policies
Run Leiden Classical 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 Leiden Classical
When you run Leiden Classical 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 Leiden Classical, and when it uses them.
The work done by your computer contributes to the goals of Leiden Classical, as described on its web site. The application programs may change from time to time.
Your account on Leiden Classical is identified by a name that you choose. This name may be shown on the Leiden Classical web site, along with a summary of the work your computer has done for Leiden Classical. If you want to be anonymous, choose a name that doesn't reveal your identity.
If you participate in Leiden Classical, information about your computer (such as its processor type, amount of memory, etc.) will be recorded by Leiden Classical and used to decide what type of work to assign to your computer. This information will also be shown on Leiden Classical's web site. Nothing that reveals your computer's location (e.g. its domain name or network address) will be shown.
To participate in Leiden Classical, you must give an address where you receive email. This address will not be shown on the Leiden Classical web site or shared with organizations. Leiden Classical may send you periodic newsletters; however, you can opt out at any time.
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. Leiden Classical 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 Leiden Classical may cause some computers to overheat. If this happens, stop running Leiden Classical or use a utility program that limits CPU usage.
Leiden Classical was developed by Leiden University - Leiden Institute of Chemistry - Theoretical Chemistry Department. BOINC was developed at the University of California.
Leiden Classical and Leiden University - Leiden Institute of Chemistry - Theoretical Chemistry Department 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 Leiden Classical.
Other projects use the same platform, BOINC, as Leiden Classical. You may want to consider participating in one or more of these projects. By doing so, your computer will do useful work even when Leiden Classical has no work available for it.
These other projects are not associated with Leiden Classical, and we cannot vouch for their security practices or the nature of their research. Join them at your own risk.
