The Discussion Forum sets a cookie with the participant's email address and name whenever a person participates in the Forum. Otherwise, all information is discarded after an unsuccessful install. For successful installs, on the other hand, only the final URL of the installed script is saved. This is used to track how many people use our products, and for how long. Every few months, the Update Notification System sends an email describing product updates.
Emails are concise and contain only product information, no ads.
Log data is not cross-referenced with identifying information. That data is viewable by all users. Fluid Dynamics Software does not, and is not allowed to, see the credit card information entered. A transaction summary, including only the purchaser's name and email address, is returned to us and saved for accounting purposes. We often send a thank-you email shortly after each transaction, but don't otherwise send mail.
