Privacy & your information

How information is used on the Human Gravity and Mark Hilliker Stewardship websites.

Book updates

If you sign up for Human Gravity updates, your email address and signup/confirmation information are stored in MailerLite. This includes information such as signup time and IP address. You confirm your subscription by email, and can unsubscribe through a link in an update email.

MailerLite may record email opens and link clicks, depending on the email settings and your email software. See MailerLite’s privacy policy.

The Gravity Gap assessment

Your answers are scored in your browser. The website does not send your individual answers to Mark when you view your result. If you choose “Send my results,” your email address, zone, aggregate scores, gap and ratio are sent through Formspree to Mark so he can respond. Requesting this follow-up does not subscribe you to book updates.

Formspree also processes technical information associated with submissions. See Formspree’s privacy policy.

Contacting Mark

When you email Mark, he receives your email address and the information you include so he can respond to your inquiry. Please avoid including confidential information about people your organization serves.

Website services

Cloudflare hosts these websites and processes technical connection information to deliver and protect them. See Cloudflare’s privacy policy. Fonts load from Google Fonts, so your browser connects to Google when displaying them. No advertising pixels or website analytics scripts have been added to these sites.

Links to MailerLite’s hosted signup form and other external services take you to services with their own privacy practices. Those services may use cookies and other technical features.
