Manufacturing Entropy Privacy

We receive no customer content

JEDI runs in your browser on your own device and reads only what you choose. Your typed logs, messages, transcripts and files stay with you. Manufacturing Entropy never receives that data: we do not receive, store or process it, and we do not deliver reports by email. JEDI has no accounts and no license check, and it does not send anything to us. Erosion Finder works the same way: the statements you load are processed only in your browser and are never sent to us. Please do not email us typed plant logs, transcripts or files.

What we collect

Payments: if you buy, our payment processor, Stripe, gives us your name, email, billing address and purchase details.

Server logs: our host (Cloudflare) may keep standard request logs such as IP address. If a page fails to load, your browser may send a short error report to Cloudflare.

Counters: we keep anonymous counts of page visits and buy-button clicks by page and link source. For each buy-button click we also record the time, the link source, a coarse browser family (such as Chrome or Safari) and whether it looks like an automated bot; these click records are deleted after 90 days. They hold no IP address, no full browser string, no cookies, no names, emails or content. Some pages use Cloudflare Web Analytics.

Packet requests: if you tick the box on the JEDI packet page, we keep the name and work email you enter, the link you came from and the time, and use them to email you the packet and occasional updates. Reply "no thanks" or email hello@manufacturingentropy.com at any time and we stop. We delete packet-request details within 30 days after you opt out, or after 24 months with no contact.

Checklist, newsletter and library sign-up: if you tick the box on the checklist form or the newsletter form, we keep your work email, your name if you enter one (name is optional), which form you used (checklist or newsletter), the consent text and version you agreed to, the link you came from and the time. Checklist form, consent version v4: "Yes, email me the 10-point plant checklist, Manufacturing Entropy newsletter editions, and occasional updates and offers from Nathan Scalf at Manufacturing Entropy, and give me access to the library of published editions and relevant reading. I can unsubscribe at any time by using the unsubscribe link in any newsletter or update email, or by emailing hello@manufacturingentropy.com." Newsletter form, consent version v3: "Yes, email me Manufacturing Entropy newsletter editions and occasional updates and offers from Nathan Scalf at Manufacturing Entropy, and give me access to the library of published editions and relevant reading. I can unsubscribe at any time by using the link in any newsletter email, or by emailing hello@manufacturingentropy.com." We use these details to email you a confirmation request, then — only after you confirm — to let you download the checklist (if you asked for it), to send newsletter editions and occasional updates and offers, and to offer access to the library of published editions and relevant reading. After you confirm, we set a signed cookie on your browser so this site can open the checklist download and the library for you. The cookie is HttpOnly, first-party, and is used only for that access; it is not used to advertise to you or to track you on other sites. Brevo is our processor for this contact list and sends the confirmation and later emails. Unconfirmed sign-ups are deleted after 30 days. Confirmed records are kept until you unsubscribe. After you unsubscribe, we keep only a suppression record so we do not email you again, and checklist and library access for that sign-up is turned off. You can unsubscribe with the unsubscribe link in any newsletter or update email we send, or by emailing hello@manufacturingentropy.com.

Email: if you email us, we keep the email.

Feedback: if you use the feedback tab, we keep your message and the page it came from for up to 1 year. Please don't include your name, email or plant data.

Use

Payments, support, refunds, tax and accounting, sending ebooks you pre-ordered to the email you gave at checkout, sending the JEDI packet and occasional updates to people who asked, and, for people who confirmed, providing the checklist download, sending newsletter editions and occasional updates and offers, and offering library access.

Sharing

Stripe and Cloudflare; our email providers (Google and Brevo, including Brevo as processor for the checklist, newsletter and library list); or where the law requires. We never sell your data.

Tracking

We do not track you across other sites.

Sensitive content

Please don't send us passwords, card numbers, health information or other people's sensitive personal data.

Changes/access

We post changes here with a new date; email hello@manufacturingentropy.com to see, correct or delete your data.
