Privacy Policy
Last updated: October 25, 2026
A short version, first.
You give us sensitive information about your body. We treat it as such. Your intake is encrypted, never sold, never used to train external models, and deletable at any time by writing to hello@yarrowandflint.com.
What we collect
Information you provide directly: your intake answers (symptoms, cycle history, lifestyle, goals), your name and email, and your billing details handled by our payment processor. We also log basic technical data — device, browser, and pages visited — to keep the site working.
How we use it
Your intake is used solely to compose, deliver, and revise your personalized PDF guide. Your email is used to send your guide, revisions, and optional seasonal refreshes you opt into. We may advertise Yarrow & Flint on platforms such as Facebook and Instagram. On our public marketing pages we use the Meta Pixel to measure those ads; it receives standard page-view information and, if you sign up, a hashed (scrambled) email address — never your quiz or intake answers or any health information. We do not share your information with third parties for their own marketing.
We never sell your personal data. We do not share your quiz or intake answers, or any health information, with advertising platforms. You can have your data deleted at any time by emailing hello@yarrowandflint.com.
Health information
Yarrow & Flint is an educational product. The information you share is treated as confidential and is not used to train external AI models. Plans are generated automatically — there is no assigned human reviewer. Your answers are processed by our systems and service providers (payment processing by Stripe, email delivery, hosting, and an AI writing service that generates your plan) only to produce and deliver your plan.
Your rights
You may request a copy of your data, correct it, or delete it entirely at any time. Requests are processed within 30 days.
