What we keep, why, and how to delete it.
Plain English. No 4,000-word legal artillery. If you're handing over your email, you should know exactly what's happening to it.
What dataffeine.com collects
Nothing. The page you're on right now sets no cookies, runs no analytics, and stores nothing about you on its own servers.
It's a static page hosted on GitHub Pages. GitHub keeps standard HTTP server logs (IP, user-agent, request path) for DDoS protection and platform abuse prevention; their privacy policy is at github.com/site-policy.
What happens when you subscribe
The subscribe form opens Substack in a new tab with your email pre-filled. From that point on, Substack — not us — is the data controller for your email.
We use Substack to send Dataffeine because it does email well, handles unsubscribes correctly, and respects sender authentication. When you confirm on Substack:
- Your email is added to Dataffeine's Substack subscriber list.
- Substack sends you Issue №001 the moment it ships, and every subsequent issue.
- Substack's privacy policy and data-handling commitments apply: substack.com/privacy.
We don't run our own database. We don't have a copy of your email outside Substack. We don't sell or share your email anywhere.
How to delete your data
Two ways. Pick whichever:
- Click the Unsubscribe link at the bottom of any Dataffeine email. Substack removes you immediately.
- Email hello@dataffeine.com with the subject "Delete my data." We'll confirm and remove you from Substack within two business days.
If we change this
We'll email every confirmed subscriber before any change that meaningfully expands what we collect. No quiet edits.
