Privacy Policy

What We Collect
The Ferment Guide is a simple content site. We collect very little data:
- Email address — only if you subscribe to our newsletter. We never sell or share your email with third parties.
- Analytics data — we use privacy-friendly analytics to understand which pages are popular. This data is aggregated and anonymous.
Affiliate Links
Some links on this site (particularly on our Tools page and within guides) are affiliate links. When you click an affiliate link and make a purchase, we may earn a small commission at no extra cost to you. These links go to Amazon and include our Associates tag.
Clicking an affiliate link does not give us access to any of your personal or purchase information. Amazon handles the transaction entirely.
Cookies
We use minimal cookies for essential site functionality (like remembering your light/dark mode preference). We do not use tracking cookies or third-party advertising cookies.
Third-Party Services
We may use the following third-party services:
- Vercel — for hosting and serving this website
- Amazon Associates — for affiliate links on product recommendations
Each of these services has its own privacy policy that governs how they handle data.
Your Rights
You can unsubscribe from our newsletter at any time using the link in any email we send. If you want us to delete any data we have about you, email us at meg@spreadaioli.com and we'll take care of it.
Changes
If we make significant changes to this policy, we'll update the date at the top of this page. We're a small site — no surprises.
