Terms of Service

Effective Date: August 10, 2026 Last Updated: September 28, 2026 Version: 1.2

1. Introduction

Welcome to Maison Saika Tokyo ("Maison Saika," "we," "us," or "our"). These Terms of Service ("Terms") govern your access to and use of our personalized skin and hair diagnosis service (the "Service") through our website maisonsaika.com (the "Site") and our mobile app.

By making a purchase or otherwise using our Service, you ("you," "your," "Client") agree to be bound by these Terms and our Privacy Policy. If you do not agree to these Terms, you must not use the Service.

These Terms should be read together with our Privacy Policy, which describes how we collect, use, and protect your personal data.

2. About Us (The Service Provider)

The Service is operated by:

Saiterace Inc. (Saiterace 株式会社) A joint-stock company organized under the laws of Japan Principal place of business: Nagoya, Japan Representative Director (代表取締役): Shinya Watanabe Contact: support@maisonsaika.com

"Maison Saika Tokyo" is a trademark and service brand owned and operated by Saiterace Inc.

3. Eligibility

To use the Service, you must:

• Be at least 18 years of age
• Have the legal capacity to enter into binding contracts in your jurisdiction
• Provide accurate and complete information when registering and during the diagnosis process
• Not be prohibited from using the Service under applicable laws

By purchasing, you confirm that you are 18 or older.

The Service is intended for individual personal use only. Commercial use, resale, or use on behalf of others is not permitted without our prior written consent.

4. Description of the Service

Maison Saika provides personalized skin and hair diagnosis reports based on:

• Photographs you take and upload through the Service (see Section 4.2)
• Questionnaire responses you provide
• Analysis and a draft report prepared with the help of artificial intelligence (AI)
• Review, editing, and final approval by a Maison Saika Curator (our beauty specialist)

Every report is reviewed and approved by a Curator before it is delivered to you. A report is not made available to you until that review is complete.

4.1 Plans

We currently offer the following plans:

Skin

• Skin Analysis — A one-time, in-depth skin diagnosis report
• Total Beauty — Skin Analysis plus makeup and personal colour guidance
• Beauty Monthly — A monthly skin diagnosis with month-to-month progress tracking, purchased one month at a time

Hair

• Hair Atelier — A one-time, in-depth hair and scalp diagnosis report
• Hair Monthly — A monthly hair and scalp diagnosis, purchased one month at a time

Bundles

• Skin and hair plans may also be purchased together as a bundle where offered on the Site.

Detailed plan features, follow-up Q&A allowances (Section 10), and pricing are shown on our website.

We do not sell or recommend specific makeup products, and we do not provide foundation shade matching.

4.2 Photographs

The photographs required depend on your plan:

• Skin: front of the face, left side, right side, and the T-zone. Total Beauty also asks for one photograph of the inner wrist, used as a skin-tone reference. From the second month of Beauty Monthly, only the front of the face is required.
• Hair: frontal hairline, crown, parting, and side of the scalp. Nape and hair-ends photographs are optional. From the second month of Hair Monthly, only the parting is required.

Every sixth month of Beauty Monthly or Hair Monthly, you may choose a full re-diagnosis. If you do, you will be asked for the same photographs as in your first month.

You must only upload photographs of yourself.

4.3 Scores and assessments

Our reports describe each area of your skin or hair as a strength, steady, or a focus for care. These descriptions are our Curators' assessment based on photographs and your answers; they are not laboratory or device measurements.

5. Important: This Is Not Medical Advice

Maison Saika is a beauty and skincare consultation service. It is NOT a medical service.

You acknowledge and agree that:

• Our reports do not constitute medical diagnosis, medical advice, or medical treatment
• Our Curators are beauty and skincare specialists, not medical doctors or dermatologists
• For any skin or scalp condition involving pain, infection, severe inflammation, suspected disease, allergic reactions, or any other medical concern, you must consult a qualified medical professional (such as a dermatologist)
• We do not prescribe medications or recommend medical procedures
• Any product or ingredient recommendations we make are general beauty suggestions, not medical prescriptions
• If you are pregnant, breastfeeding, undergoing medical treatment, or taking medication, you should check with your doctor before using any product or ingredient we suggest. Unless you have told us about these conditions in your questionnaire, our recommendations do not take them into account
• You are solely responsible for your decisions regarding your skin, hair, and overall health

If you experience any adverse reaction, irritation, or other negative effect from following our recommendations, you should immediately discontinue use and consult a medical professional.

6. Access to Your Diagnosis and Security

We do not use passwords for Clients. Access to your diagnosis, questionnaire, and report is provided through a private access token:

• When you register, the token is stored in your browser, so you can continue on the same device
• Links containing the token are also sent to you by email (for example, when your payment is confirmed, when your Curator is assigned, and when your report is delivered)
• If you use our mobile app, a one-time code in your delivery email links the app on your device to your diagnosis

You are responsible for:

• Keeping your private links, confirmation emails, and device secure, and not sharing them with others
• All activities that occur using your access link or app
• Notifying us immediately at support@maisonsaika.com if you believe someone else has gained access

We reserve the right to suspend or terminate your access if we have reasonable grounds to believe that:

• You have provided false or misleading information
• You have violated these Terms or our Privacy Policy
• You have engaged in fraudulent activity, abuse, or harassment
• You have repeatedly initiated unjustified chargebacks
• You have uploaded photographs of any person other than yourself

7. Payment Terms

7.1 Currency and Processing

All prices on our website are shown in USD ($), and payments are processed in USD via Stripe. If your card is issued in another currency, the amount charged to your account depends on your bank's exchange rate at the time of the transaction, plus any foreign transaction fees your bank may apply.

Product prices shown in Indian rupees (₹) inside your report or on our showcase pages are approximate retail prices of third-party products, for your reference only. We do not sell those products, and those prices are not charges from us.

7.2 Pricing

Current pricing for each plan is displayed on our website. We reserve the right to change pricing at any time, but changes will not affect purchases already made.

7.3 Founding Clients Offer

The Founding Clients Offer is available to the first 30 clients only and provides:

• A discount of approximately 30% on your first purchase
• The same Founding discount, permanently, on all future Maison Saika services

The exact Founding price for each plan is shown on our website.

To receive the Founding price as a new client, begin through a Founding invitation link while spots remain available. Founding status is linked to the phone number used at purchase, one spot per phone number. Once you are a Founding client, the discount applies automatically to your future purchases. Once 30 clients have claimed Founding status, the offer will close to new clients.

7.4 Monthly Plans (Beauty Monthly, Hair Monthly)

Beauty Monthly and Hair Monthly are purchased one month at a time. There is no automatic renewal, and we do not hold a payment mandate on your card. Each month is a separate purchase that you choose to begin, and nothing is charged unless you begin it.

Because nothing recurs, there is nothing to cancel. If you decide not to continue, simply do not begin a new month — no further charges will occur, and your past reports and progress history remain accessible.

We will let you know when a new month is available to you. That message is an invitation, never a charge.

8. Refund Policy

We aim to be fair and transparent. Our refund policy is structured as follows:

8.1 Before Report Delivery

If you have not yet received your diagnosis report, you may request a full refund within 7 days of purchase by contacting support@maisonsaika.com. We will process the refund within 14 business days.

8.2 If You Have Not Submitted Photos or Questionnaire

If you have purchased a plan but have not yet submitted your photos or questionnaire, you may request a full refund at any time before submission, regardless of the 7-day window.

8.3 After Report Delivery

Once your diagnosis report has been delivered, refunds are evaluated on a case-by-case basis. We will consider partial or full refunds in cases of:

• Demonstrable quality issues with the report (e.g., factual errors, missing sections)
• Failure to deliver the promised service features
• Other clear service defects

To request post-delivery refund consideration, contact support@maisonsaika.com within 7 days of report delivery, providing specific details of the issue.

8.4 Non-Refundable Situations

The following situations are not eligible for refunds:

• Subjective dissatisfaction (e.g., "I expected a different recommendation")
• Results not meeting expectations due to non-adherence to our recommendations
• Adverse reactions caused by products you purchased independently based on our suggestions
• Completed months of Beauty Monthly or Hair Monthly (each month is purchased and delivered separately; a delivered month is non-refundable under Section 8.3)
• Charges related to currency conversion or foreign transaction fees imposed by your bank

8.5 Chargeback Disputes

If you initiate a chargeback through your bank without first contacting us, we may suspend or terminate your access and decline to provide further service. We always prefer to resolve issues directly.
