Short, human, honest.

CODE IV is published by GuyFin LLC, a New Jersey limited liability company (the “publisher,” “we,” “us”). One editor. No parent company, no investors, no ad network.

Reach us at hello@codeiv.co. We read every message.

When you subscribe, we collect:

• Your email address.
• The date you subscribed and which page you subscribed from.
• Whether you open or click links in the weekly dispatch.
• Standard server logs from each visit (IP address, browser type, referrer, time of request), used only to keep the site running and identify abuse.

We do not ask for your name, license number, employer, or any other identifier. We never collect health information about you or your patients from the website.

• To deliver the weekly email you signed up for.
• To improve the publication based on what readers actually open and click, anonymized, in aggregate.
• To keep the site running and prevent abuse.

We use a small number of vendors to run the site and deliver the newsletter. Each one has access to a specific slice of the data, never the whole picture.

That’s the full list. We do not run third-party advertising networks, retargeting pixels, or social-media trackers. We do not sell your data to anyone, ever.

The site uses a small number of first-party cookies and similar storage to remember your dark-mode preference and to power anonymized analytics. The newsletter itself uses tracking pixels in emails to count opens and clicks.

Full breakdown on the Cookies page.

We keep your subscriber record as long as you’re subscribed. When you unsubscribe, we mark you as inactive and stop sending. We may keep a basic record (email + unsubscribe date) so we don’t accidentally re-add you.

Server logs and engagement events are retained in line with our processors’ standard policies and only as long as we need them to keep the site running.

You can do any of these at any time, free of charge:

• Unsubscribe. Every email has a one-click link at the bottom.
• Ask for a copy of the data we hold about you.
• Ask us to correct or delete your data.
• Ask us to stop sending you emails (same thing as unsubscribe).
• Ask us to export your data so you can move it elsewhere.

Email hello@codeiv.coand we’ll handle it within 30 days. No friction, no “why are you leaving” surveys.

CODE IV writes about clinical work for an audience of clinicians. Nothing we publish is medical advice for a specific patient. Every clinical piece is general — a protocol, a pattern, a question worth asking. Make your scene, your shift, and your patient decisions with your agency’s protocols, your medical director, and your scope of practice.

When you submit a story, strip anything that could identify a patient, coworker, or facility before you hit send. Names, dates of birth, addresses, unit numbers, badge numbers, distinctive injuries, photos. We will ask you to rewrite if identifiers show up. Protecting patient privacy is non-negotiable.

CODE IV is not a HIPAA covered entity or business associate. That doesn’t give anyone a pass — your duty to protect patient information follows you into this newsletter.

If you’re based in the EU, UK, or EEA, GDPR applies to your data. The short version of how we comply:

• Legal basis for sending you the newsletter: your consent (you signed up).
• Legal basis for our analytics and security: legitimate interest in keeping the site working and free of abuse.
• You have the right to withdraw consent at any time. Hit the unsubscribe link in any email.
• You have the right to lodge a complaint with your local data-protection authority. The Irish Data Protection Commission is a common starting point for EEA users.

GuyFin LLC is the data controller. Email hello@codeiv.co with anything GDPR-related.

If you’re a California resident, CCPA gives you the right to know what personal information we have, to delete it, and to opt out of any “sale.” We don’t sell personal information, so opting out of a sale isn’t really a thing here. Email hello@codeiv.cofor any CCPA request and we’ll respond within 45 days.

CODE IV is not directed at children under 16. We don’t knowingly collect data from them. If you’re a parent or guardian and you believe a minor has subscribed, email us and we’ll remove the record.

The site is served over HTTPS. Beehiiv and Vercel both encrypt data in transit and at rest. We don’t run our own database; we don’t store your email anywhere we control beyond what’s required to render and operate the site.

If you ever spot a security issue, write to hello@codeiv.co.

Beehiiv and Vercel are US-based. If you’re subscribing from outside the US, your data will be transferred to and processed in the US under standard contractual clauses or equivalent safeguards required by your jurisdiction.

If we change anything material, we’ll update the “Last updated” date at the top and, for substantive changes, mention it in the next dispatch. We won’t make a quiet edit and pretend nothing changed.

Email hello@codeiv.co and a human will answer.
