Contact: mark@qtrac.eu.
Director: Mark Summerfield.

We own www.qtrac.eu and www.diffpdf.com. Both are mapped to our underlying web site which is hosted on Google infrastructure at diffpdf.appspot.com.

Our software normally uses www.qtrac.eu if you request a free trial license key or to buy, with buy requests then being redirected to MyCommerce (order.shareit.com) who provide secure money handling. (Our website never sees or has access to your means of payment.)

Support for our software is via email at support@qtrac.eu, support@qtrac.uk, or support@diffpdf.com.

All of our books are published by Pearson Education (InformIT).
