Privacy Policy

Last updated: November 10, 2026

This policy explains what information the Sienne Method ("Sienne," "we," "us") collects when you use thesiennemethod.com and the Style Profile questionnaire, how we use it, and the choices you have. We wrote it in plain language on purpose — if anything here is unclear, reach out using the contact information at the bottom of this page.

Information We Collect

Information you provide directly

Information collected automatically

We do not currently use advertising or analytics tracking cookies on this site. Your browser may use limited local storage for basic site functionality (for example, to keep an administrator signed in); this is not used to track visitors across other websites or shared with advertisers.

How We Use Your Information

We do not sell your personal information, and we do not use it for third-party advertising.

Who We Share Information With

We use a small number of outside companies ("service providers") to operate Sienne. Each one only receives the information it needs to do its specific job:

Service providerWhat it's used forWhat it receives
SupabaseSecurely stores your profile record and powers passwordless sign-inName, email, questionnaire answers, your generated report, payment status
Anthropic (Claude)Generates your personalized, AI-written style reportYour questionnaire answers (not your name or email)
StripeProcesses payment for the $47 capsule unlockPayment details, your email
ResendDelivers the emails Sienne sends youYour name and email
OpenWebNinjaLooks up real, currently available products for your capsule wardrobeGeneric search terms (item type, general size range) — never your name or email

We may also share information if required by law, or to protect the rights, safety, or property of Sienne or our customers.

Passwordless Sign-In

To let you return to a style profile you've already completed, Sienne uses secure, one-click sign-in links sent to your email instead of a password. These links are personal to you and expire after a short time. Don't forward a sign-in link to anyone else — treat it the way you'd treat a password.

Data Retention

We keep your profile information for as long as your account is active, so you can return to your style profile later. If you'd like your information deleted, contact us (see below) and we will remove it, except where we're required to keep certain records (for example, payment records Stripe may retain for tax or fraud-prevention purposes).

Your Choices

Children's Privacy

Sienne is intended for adults and is not directed at children. We do not knowingly collect information from anyone under 18.

Security

We use industry-standard measures to protect your information, including encrypted connections (HTTPS) and a PCI-compliant payment processor (Stripe) that never shares your full card details with us. No method of transmission or storage is 100% secure, but we take reasonable steps to protect your information.

Changes to This Policy

We may update this policy from time to time. The "Last updated" date at the top of this page reflects the most recent changes. Continued use of the Sienne Method after changes take effect means you accept the updated policy.
