Short, because we collect little.
Last updated July 2026.
What we collect
When you write to us through the contact form, we collect what you type: your name, email address, the topic you choose, and your message. That's the full list. This site has no advertising trackers. If we launch a newsletter, subscribing will mean giving us your email address, and this policy will say so before it happens.
How we use it
Contact messages are delivered to our inbox by an email service provider and used solely to reply to you. If we launch a newsletter, subscriber addresses will be used solely to send it, and every issue will include an unsubscribe link.
Analytics
We don't run analytics on this site today. If we add privacy-respecting, cookie-free analytics later, this policy will say so before it happens.
Your choices
Email hello@caygnus.com to ask what we hold about you, to correct it, or to have it deleted. We honor all three without ceremony.
