Account & Marketing: How We Handle Your Data

Last updated: August 6, 2026

What this covers

This notice is about creating a Fibertarian account and the optional marketing opt-in offered at signup and from your account page. It doesn't cover the Elixir Lab's health-data handling — see the Elixir Lab privacy noticefor that. Saving a formula to your account is governed by both notices together.

Creating an account

Signing up is passwordless — there's no password to choose, leak, or reuse. To create an account we collect:

• Your email address, to send you a one-time sign-in link and verify it's really you
• Your name, if you choose to give it

That's the whole account record. We don't collect anything else to create it.

Marketing is a separate, optional choice

At signup — and any time after, from your account page — you can opt in to occasional nutrition emails from Fibertarian. This choice is:

• Optional and unchecked by default. Creating an account, saving a formula, and receiving your emailed protocol all work whether or not you opt in.
• Withdrawable any time, self-service, from your account page — no need to contact us.
• Never linked to your health information. If you opt in, we send our marketing system only your email, your name if you gave one, and the fact that you came from the Elixir Lab — never your declared conditions, medications, markers, or saved formula.

Where account data lives

Your account and its consent records are stored in our database provider (Supabase, hosted in the United States), encrypted in transit and at rest, and readable only by you through your own logged-in session.

We do not sell this

We never sell your account or marketing-consent data, and we never share it with anyone beyond the marketing system you've explicitly opted into.

Your controls

• Withdraw marketing consent any time from your account page.
• Ask us. For anything our self-service tools don't cover, contactprivacy@fibertarian.com.

This is not medical advice

Nothing about your account or marketing preferences changes this: the Elixir Lab, your saved customization, and any protocol emailed to you are informational tools — not medical advice, a diagnosis, or a treatment recommendation. Always discuss changes to your diet or supplement routine with your doctor.
