If you use the contact form, it will ask for your first and last name and eMail address. This helps me know who I need to reply to and where to send that reply. By using the site contact form, you consent to this information being used for the stated purpose.
This site uses tracking and analytics tools such as Google Analytics to measure data about site traffic such as visitor engagement, the types of devices and browsers used to access content (i.e., mobile versus desktop, Google versus Bing), visitor retention, and demographics such as from which countries the site is being accessed. This site also uses Pinterest tracking to ensure any artwork or images crossposted are properly credited back to this site (but you should still credit it yourself anyway).
