Terms of use

Phasorium is free to read. These terms say what you may do with its lessons and on what terms the site is provided.

As it is

The site is provided as it is, without warranty. The numbers are checked with care, but no page is promised to be free of error, and the site is not promised to be always available. Where a mistake could cause harm, check against a primary source. As far as the law allows, Phasorium is not liable for loss that comes from using the site.
