Privacy policy
Last updated October 1, 2026
Placeholder. This is a plain-language starting point, not legal advice. Have it reviewed before launch, especially if you collect emails from people outside the United States.
Iterwillow is built to collect as little as possible. Here is everything, in plain words.
Browsing the site
- We do not use advertising or tracking cookies, and we do not sell data.
- We use Cloudflare Web Analytics, which counts visits without cookies and without building a profile of you.
- Your light or dark theme choice and your motion setting are saved in your own browser so the site remembers them. They never leave your device.
Videos
Lesson videos are hosted on YouTube. Nothing from YouTube loads until you press play. When you do, the video plays from YouTube's privacy-enhanced domain (youtube-nocookie.com), and YouTube's own privacy policy applies to that video.
The newsletter
- If you sign up, we store your email address and, if you give it, your first name.
- We use them only to send the newsletter. We never sell or share them.
- Signups are stored in a Google Sheet that only we can access.
- To block spam, the form uses Cloudflare Turnstile, which checks that you are a person. We also keep a short-lived, anonymized count of signup attempts to stop abuse.
- Every email has an unsubscribe link. You can also email[email protected] and we will delete your details.
Tips
If you leave a tip through Ko-fi or GitHub Sponsors, that payment is handled entirely by them, under their privacy policies. We never see your card details.
