Privacy Policy

Last updated: May 13, 2026

Your privacy matters to us. This policy explains what information Ferment Calculator (fermentcalculator.com) collects, how we use it, and what choices you have.

1. What we collect

Analytics data

We use analytics software (such as Google Analytics or Plausible Analytics) to understand how people use the Site. This may include:

  • Pages visited and time spent on each page
  • General geographic location (country/region — not precise location)
  • Device type, browser, and operating system
  • Referring website or search query

This data is aggregated and anonymous. We use it to understand which tools are most useful and to improve the Site. We do not use it to identify you personally.

If we use Google Analytics, data is processed in accordance with Google’s Privacy Policy. You can opt out of Google Analytics tracking using the Google Analytics Opt-out Browser Add-on.

If we use Plausible Analytics, it is a privacy-first tool that does not use cookies and does not collect personally identifiable information.

Email subscriptions

If you subscribe to our newsletter, we collect your email address. We use it to send you updates about new calculators, guides, and fermentation content.

We use a third-party email platform to send these messages. Your email address is stored on that platform’s servers and processed in accordance with their privacy policy.

You can unsubscribe at any time via the link in any email we send. After unsubscribing, your email address will be removed from our active mailing list.

We will never sell or rent your email address to anyone.

Contact form submissions

If you use our contact form, we receive the message and email address you submit. We use this only to respond to your inquiry.

2. Cookies

The Site may set cookies for analytics purposes. These are small text files stored in your browser that help analytics tools distinguish between visitors.

Plausible Analytics (if used) is cookieless. Google Analytics (if used) uses cookies.

You can control or delete cookies through your browser settings. Disabling cookies will not affect the functionality of the calculators.

Some pages contain affiliate links to products on third-party retailers (e.g., Amazon). Clicking these links may set cookies on those retailers’ sites, which they use to track purchases for commission purposes. We do not receive any personal data from these retailers — only aggregate commission information.

4. Calculator data

The calculators on this Site run entirely in your browser. Any numbers you enter into a calculator are not transmitted to our servers. We do not store, log, or process your calculator inputs.

5. Third-party services

We may use third-party services for hosting, analytics, and email delivery. These services process data on our behalf under their own privacy policies. We encourage you to review the policies of any third-party service you interact with.

6. Children’s privacy

This Site is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has submitted personal information to us, please contact us and we will delete it.

7. Data retention

Analytics data is retained per the terms of the analytics provider. Email addresses are retained until you unsubscribe. Contact form messages are retained only as long as needed to respond to your inquiry.

8. Your rights

Depending on where you live, you may have rights regarding your personal data — including the right to access, correct, or delete information we hold about you. To exercise any of these rights, contact us.

9. Changes to this policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the “Last updated” date at the top of this page.
