Coileen Curl Coach — Terms and Conditions

Last updated: 21 October 2026 Effective date: 21 October 2026

Please read these Terms and Conditions ("Terms") carefully before using the Coileen Curl Coach application, website, and related services (together, the "App" or "Service").

The App is operated by Marching Brands LLC, a limited liability company formed in Delaware, United States ("Coileen", "we", "us", "our"). "Coileen Curl Coach" is a brand and product of Marching Brands LLC.

By downloading, accessing, creating an account on, or using the App, you agree to be bound by these Terms. If you do not agree to these Terms, do not use the App.

1. Summary of the most important points

This summary is for convenience only and does not replace the full Terms below.

Coileen uses artificial intelligence to analyse hair product ingredients and generate personalised suggestions. AI can and does make mistakes.
Coileen is not a doctor, dermatologist, trichologist, or cosmetic chemist, and nothing in the App is medical advice.
Always check that any suggestion makes sense before acting on it, read the actual product label, and patch test new products.
Consult a qualified medical professional for any scalp, skin, hair-loss, allergy, or health concern — and any time you are in doubt.
To the fullest extent permitted by law, Coileen is not liable for allergic reactions, irritation, hair or scalp damage, product costs, or any other loss arising from your use of the App.
Premium is $19.99 per month, auto-renewing, cancel anytime, with a conditional 30-day money-back guarantee described in Section 9.

2. Eligibility

2.1 You must be at least 18 years old to create an account, purchase a subscription, or otherwise use the App.

2.2 By using the App you confirm that you are 18 or over and have the legal capacity to enter into these Terms.

2.3 You may not use the App if you have previously been suspended or removed from the Service, or if doing so would breach any law that applies to you.

2.4 If we become aware that an account belongs to someone under 18, we may suspend or close it and delete the associated data.

3. What Coileen is (and what it is not)

3.1 What the App does. Coileen allows you to build a hair profile (which may include curl type, porosity, strand thickness, density, elasticity, damage level, scalp sensitivity, and styling goals), scan or enter hair product ingredient lists, converse with an AI hair coach, save products to My Shelf, browse a style guide, and use the AI Hair Styler. In return you receive automated, personalised analysis, scores, ingredient breakdowns, routine suggestions, and styling tips.

3.2 What the App is not. The App is an informational and educational tool only. It is:

not medical, dermatological, or healthcare advice;
not a diagnosis, treatment, or prescription of any kind;
not a laboratory analysis or safety certification of any product;
not a guarantee that a product is safe, effective, suitable, or accurately labelled;
not a substitute for reading the physical product label and manufacturer's instructions;
not a substitute for the advice of a doctor, dermatologist, trichologist, pharmacist, allergist, or licensed stylist.

3.3 No professional relationship. Using the App does not create a doctor–patient, therapist–client, or any other professional or fiduciary relationship between you and Coileen.

3.4 Individual results vary. Hair and scalp responses are highly individual. A product that suits one person may not suit another with an apparently identical hair profile. We make no promise of any particular result, including any amount of hair growth, length retention, curl definition, or reduction in breakage.

3.5 Coileen the coach is an AI persona. "Coileen" is the name of the AI coach within the App. She is a software system, not a person, and not a qualified professional of any kind.

4. Artificial intelligence — important disclaimer

This section is important. Please read it in full.

4.1 You are interacting with an AI system. The analysis, scores, recommendations, coaching responses, explanations, and tips shown in the App are generated in whole or in part by artificial intelligence and automated systems, including third-party large language models. They are not individually written, reviewed, or approved by a human expert before you see them.

4.2 AI can make mistakes. AI systems can be wrong. Output may be:

inaccurate, incomplete, or out of date;
confidently stated but factually incorrect ("hallucinated");
based on a misread, partially scanned, or badly lit ingredient list;
based on general patterns that do not apply to your specific hair, scalp, health, or circumstances;
inconsistent between one scan or conversation and another for the same product.

4.3 You must sanity-check every suggestion. Always check that any advice or analysis makes sense before following it. Before you act on anything the App tells you, you should:

read the actual ingredient list and warnings on the physical product packaging;
confirm the App has identified the correct product and captured the full ingredient list;
consider your own known allergies, sensitivities, medical conditions, medications, and past reactions;
patch test any new product on a small area of skin, following the manufacturer's instructions, before full use;
seek professional advice if anything is unclear, surprising, or does not match what you already know about your hair.

4.4 Consult a medical professional. You should contact a doctor, dermatologist, allergist, or other qualified medical professional:

before using any product if you have a known allergy, sensitivity, skin condition, or scalp condition;
if you are pregnant, breastfeeding, or being treated for any medical condition;
if you experience any reaction, irritation, burning, rash, swelling, breathing difficulty, hair loss, or other adverse effect;
for any hair loss, scalp disease, infection, or persistent symptom;
any time you are in doubt.

If you experience a severe reaction — including difficulty breathing, swelling of the face, mouth or throat, dizziness, or widespread rash — stop using the product immediately and seek emergency medical help. Do not rely on the App in an emergency.

4.5 You decide. All decisions about which products to buy, use, combine, or apply — and how — are yours alone. You use the App's output entirely at your own risk and on your own judgement.

4.6 Ingredient data limitations. Ingredient information may come from optical scanning, user submissions, public databases, manufacturer listings, and other third-party sources. Formulations change without notice, labels are sometimes incomplete or mistranslated, and databases contain errors. We do not independently verify, test, or certify any product or ingredient.

4.7 Data sent to third parties. To generate analysis and coaching, content you submit — including ingredient text and images, photographs used by the AI Hair Styler, and elements of your hair profile — may be processed by third-party AI providers, including Anthropic. See our Privacy Policy for details. Do not submit sensitive personal, medical, or confidential information that you do not wish to be processed in this way.

4.8 Training material. The App's coaching content draws in part on the educational material behind the Double Beauty 30-Day Hair Growth Challenge. That material is general education, not personal advice. Results reported by Challenge participants were self-measured and self-reported, were achieved using a separate product kit that the App does not supply, and are not a prediction of your results.

5. Allergic reactions and adverse effects

5.1 Coileen cannot detect or predict your allergies. The App does not and cannot know your full medical history, allergy profile, or how your skin will respond to any substance. An analysis that does not flag an ingredient is not a statement that the ingredient is safe for you.

5.2 Patch testing is your responsibility. You agree to patch test new products and to follow all manufacturer instructions and warnings.

5.3 Assumption of risk. You knowingly and voluntarily assume all risk of allergic reaction, irritation, contact dermatitis, chemical burn, hair damage, hair loss, discolouration, scalp injury, or any other adverse effect arising from products you choose to use, whether or not those products were scanned, scored, or suggested by the App.

5.4 Report and seek help. If you have an adverse reaction, stop use immediately, seek medical advice, and consider reporting it to the product manufacturer and to the relevant safety authority. In the United States that is the Food and Drug Administration (FDA), which accepts cosmetic adverse event reports through MedWatch. Elsewhere, report to your national cosmetics safety authority.

6. Your account

6.1 You need an account to use the App beyond the free hair profile quiz. You agree to provide accurate information and keep it up to date.

6.2 You are responsible for keeping your login credentials confidential and for all activity under your account. Tell us promptly at hello@coileen.com if you suspect unauthorised use.

6.3 Accounts are personal and non-transferable. You may not share your account or allow others to use your subscription.

6.4 We may suspend or terminate accounts that breach these Terms, are used unlawfully, or that we reasonably believe pose a risk to the Service or other users.

7. Your hair profile and other content

7.1 Your content. "User Content" means anything you submit, including hair profile answers, photographs, ingredient scans, messages to the AI coach, reviews, and community posts. You retain ownership of your User Content.

7.2 Licence to us. You grant Coileen a worldwide, non-exclusive, royalty-free, sublicensable licence to host, store, reproduce, adapt, and process your User Content for the purposes of operating, securing, improving, and providing the Service. This licence ends when you delete the content or your account, except for copies retained in backups or as required by law.

7.3 Photographs. Photographs you upload — including for the AI Hair Styler — are processed to deliver the feature you requested. We will not use your photographs in marketing or publish them without your separate, express written permission.

7.4 Testimonials. If you share a review or result and we wish to publish it, we will ask for your permission first and will publish it as written, attributed by first name and initial only, unless you agree otherwise.

7.5 Your responsibility. You confirm that you have the rights to submit your User Content and that it does not infringe anyone's rights or break any law.

7.6 Accuracy matters. The App's output depends on the accuracy of the profile and scans you provide. Inaccurate or incomplete input will produce inaccurate output.

7.7 Removal. We may remove User Content that breaches these Terms.

8. Acceptable use

You agree not to:

use the App for any unlawful purpose or in breach of any regulation;
present the App's output as professional, medical, or safety advice to others;
resell, republish, scrape, mine, or commercially exploit the App's content, ingredient analyses, scoring methodology, or database without our written permission;
reverse engineer, decompile, or attempt to extract the underlying models, prompts, or source code;
use the AI coach to generate content unrelated to hair care, or attempt to bypass its safety instructions;
use automated means (bots, scrapers, crawlers) to access the Service;
upload malware, attempt to breach security, or interfere with the Service's operation;
impersonate any person or misrepresent your affiliation;
upload photographs of any person without their consent;
harass, abuse, or post hateful, defamatory, or discriminatory content in any community feature;
submit false, misleading, or deliberately corrupted product or ingredient data.

9. Subscriptions, pricing, and refunds

9.1 What is free and what is paid

The hair profile quiz is free. All other features — including the product scanner, the AI coach, the style guide, the AI Hair Styler, and My Shelf — require an active Coileen Premium subscription.

9.2 Plans and pricing

Prices are in US dollars and are shown at the point of purchase. Current plans:

Monthly — $19.99 per month, renewing at $19.99 per month.
First month introductory — $14.99 for the first month, then renewing at $19.99 per month.
3-Month Starter — $27 for the first 3 months, then renewing at $19.99 per month.
Annual — $199 per year, renewing at $199 per year.

The 3-Month Starter is an introductory trial period; unless cancelled before it ends, it automatically converts to a monthly subscription at $19.99 per month. The introductory first-month price likewise renews at the standard monthly rate.

9.3 Automatic renewal and cancellation

All plans renew automatically at the end of each billing period until cancelled, at the renewal price shown in Section 9.2. You may cancel at any time, effective at the end of the current billing period. Cancelling stops future charges; it does not refund the period already paid for, except under the guarantee in Section 9.5 or where the law requires otherwise.

How to cancel. You can cancel in your account settings at any time, without having to call or speak to anyone, or by emailing hello@coileen.com. We will confirm your cancellation by email. Several US states require that cancelling an auto-renewing subscription be as easy as signing up, and we intend to meet that standard everywhere.

9.4 Payment, taxes, and price changes

Payments are processed by Stripe. We do not store your full card details. Prices are stated exclusive of any applicable sales tax or VAT unless shown otherwise at checkout; the final amount payable, including any tax, is displayed before you confirm. We may change prices for future billing periods and will give you at least 30 days' notice before a change affects you; you may cancel before it takes effect.

9.5 30-day money-back guarantee

We offer a 30-day money-back guarantee on all plans, subject to one condition: you must have chatted with Coileen on at least 5 different days during that period. The guarantee exists so that people who genuinely use the App and find it does not help them are not out of pocket — it is not a free trial.

To claim, email hello@coileen.com within 30 days of your initial purchase. Approved refunds are returned to the original payment method within 14 days.

9.6 Your right of withdrawal (EU and EEA consumers)

If you are a consumer in the EU or EEA, you have 14 days from the start of your subscription to withdraw, without giving a reason and without any conditions. We do not ask you to waive this right.

To withdraw, email hello@coileen.com within those 14 days and tell us you are withdrawing. You do not have to explain why. We will refund you within 14 days of receiving your request, to the payment method you used. Where you have already used the Service during that period, we may retain a proportionate amount for the days you had access.

This sits alongside the 30-day guarantee in Section 9.5, which is open to everyone, runs for longer, and asks only that you have actually used the App. Use whichever suits you better: within your first 14 days, withdrawal is the simpler route, because nothing is required of you beyond asking.

Your statutory rights if the Service is faulty or does not match what was promised are unaffected (Directive (EU) 2019/770).

9.7 Bonuses and founding-member perks

From time to time we offer bonuses alongside a subscription. Current examples:

a free 30-Day Hair Growth Challenge e-book, offered with the 3-Month Starter and Annual plans when you join within 7 days of being offered it;
founding-member status for the first 100 subscribers on any plan, which currently includes one live session with the founders in December 2026 and a Coileen-branded satin bonnet.

Bonuses are promotional extras, not part of the paid Service. The satin bonnet is mailed to US addresses only, shipped after your first month and after the 30-day guarantee window has closed. Bonuses have no cash value, cannot be exchanged, and are forfeited if you claim a refund. Live sessions are subject to scheduling and may be rescheduled or replaced with a recording.

9.8 App store purchases

If in future you subscribe through the Apple App Store or Google Play, billing, renewal, cancellation, and refunds for that purchase are handled by that store under its own terms and refund policy, and the guarantee in Section 9.5 may not apply.

10. Third-party products, brands, and links

10.1 Product names, brand names, and trademarks referenced in the App belong to their respective owners. Their appearance does not imply affiliation with, endorsement by, or partnership with those owners.

10.2 Coileen does not manufacture, sell, test, or certify any hair product. Any dispute about a product — including its quality, labelling, or safety — is between you and the manufacturer or retailer.

10.3 Where the App discusses brand ownership or corporate structure, those statements are drawn from public company filings, press releases, and trade press, and are offered as factual information rather than as an accusation against any company.

10.4 The App may contain links to third-party sites or, where disclosed, affiliate links. We are not responsible for third-party content, products, or practices.

11. Our intellectual property

11.1 The App — including its software, design, text, illustrations, scoring methodology, AI prompts and persona, style guide content, and branding — is owned by Coileen or its licensors and protected by intellectual property laws.

11.2 We grant you a limited, personal, non-transferable, revocable licence to use the App for your own personal, non-commercial use, subject to these Terms and to an active subscription where one is required.

11.3 Any e-book, guide, or other downloadable product is licensed for your personal use only. You may not redistribute, resell, or share it.

11.4 All rights not expressly granted are reserved.

12. Disclaimer of warranties

12.1 To the fullest extent permitted by law, the App and all content, analyses, scores, coaching responses, and recommendations are provided "as is" and "as available", without warranties of any kind, express or implied.

12.2 We specifically disclaim all implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.

12.3 We do not warrant that the App will be uninterrupted, secure, or error-free, or that any analysis, score, or recommendation will be accurate, complete, current, or suitable for you.

12.4 Nothing in these Terms excludes or limits any liability that cannot lawfully be excluded or limited, including liability for death or personal injury caused by negligence, for fraud, or for willful misconduct or gross negligence. Some US states do not allow the exclusion of certain implied warranties, so parts of this section may not apply to you. If you are a consumer, your mandatory statutory rights — including, for consumers in the EU and EEA, conformity rights for digital content — are unaffected by this section.

13. Limitation of liability

13.1 To the fullest extent permitted by law, Coileen, its owners, directors, employees, contractors, and suppliers are not liable for any loss or damage arising from or connected to your use of the App, including:

allergic reactions, skin or scalp irritation, chemical burns, or other adverse physical reactions;
hair damage, breakage, dryness, hair loss, or colour change;
the cost of products purchased, discarded, or replaced;
decisions made in reliance on AI-generated analysis, scores, ingredient interpretations, coaching, or tips;
inaccurate, incomplete, outdated, or mis-scanned ingredient or product information;
delay, interruption, data loss, or unavailability of the Service;
any indirect, incidental, special, consequential, or punitive damages, or loss of profits, revenue, data, or goodwill.

13.2 This applies regardless of the legal basis of the claim and whether or not we were advised of the possibility of such damage.

13.3 Cap on liability. Where liability cannot be excluded, our total aggregate liability to you for all claims arising in any 12-month period is limited to the greater of (a) the total amount you paid us in the twelve (12) months before the event giving rise to the claim, or (b) USD 50.

13.4 Section 12.4 applies to this section as well.

14. Indemnity

To the extent permitted by law, you agree to indemnify and hold harmless Coileen and its personnel from any claim, liability, loss, or expense (including reasonable legal fees) arising from your breach of these Terms, your User Content, your misuse of the App, or your use of any product. This clause does not apply to the extent you are acting as a consumer and the law prohibits it.

15. Privacy and data protection

15.1 Your personal data is handled in line with our Privacy Policy at coileen.com/privacy, which forms part of these Terms.

15.2 We process personal data in accordance with the GDPR. The Privacy Policy explains your rights of access, rectification, erasure, restriction, portability, and objection, how to exercise them, how long data is kept, and which third-party processors (including AI providers) receive your data.

15.3 Your hair profile answers, scan history, and coach conversations are used to personalise the Service. Where we use data for any purpose beyond that, we will say so in the Privacy Policy and obtain consent where required.

15.4 You may request deletion of your account and associated data at any time by emailing hello@coileen.com.

16. Changes to the App and these Terms

16.1 We may add, change, suspend, or discontinue features. If we materially reduce a paid feature during a paid period, you may cancel and request a pro-rata refund for the unused portion.

16.2 We may update these Terms. If changes are material, we will give at least 30 days' notice in-app or by email before they take effect. Continuing to use the App after the effective date means you accept the updated Terms. If you do not accept them, you may stop using the App, close your account, and request a pro-rata refund for any unused paid period.

17. Termination

17.1 You may stop using the App and delete your account at any time.

17.2 We may suspend or terminate your access if you breach these Terms or if we discontinue the Service. Where we terminate without fault on your part, we will refund the unused portion of any paid period.

17.3 Sections that by their nature should survive termination — including Sections 3, 4, 5, 7.2, 11, 12, 13, 14, 18, and 19 — will survive.

18. Governing law and disputes

18.1 These Terms are governed by the laws of the State of Delaware, United States, excluding its conflict of law rules and the UN Convention on Contracts for the International Sale of Goods.

18.2 Subject to 18.3, disputes will be submitted to the state or federal courts located in Delaware, and you and we consent to their jurisdiction.

18.3 Consumers keep their local protections. If you are a consumer, this choice of law and venue does not deprive you of the protection of mandatory consumer law in your country or state of residence, and you may bring proceedings there where the law allows it. For consumers in the EU and EEA this includes the rights referred to in Sections 9.6 and 12.4.

18.4 Informal resolution first. Before starting formal proceedings, please contact us at hello@coileen.com. We aim to respond within 14 days. Many disputes can be settled this way. If you are an EU or EEA consumer and we cannot resolve the matter, you may be entitled to refer it to a consumer alternative dispute resolution body in your country.

18.5 No arbitration clause or class-action waiver applies to these Terms. We have chosen not to require arbitration. Nothing here prevents either of us from bringing an individual claim in small claims court.

19. General

19.1 Entire agreement. These Terms, together with the Privacy Policy and any plan-specific purchase terms, are the entire agreement between you and Coileen regarding the App.

19.2 Severability. If any provision is found unenforceable, the rest remains in force and the unenforceable provision is modified to the minimum extent necessary.

19.3 No waiver. Failure to enforce a provision is not a waiver of it.

19.4 Assignment. You may not assign your rights under these Terms. We may assign ours to an affiliate or in connection with a merger, acquisition, or sale of assets, provided your rights are not reduced.

19.5 Force majeure. We are not liable for failure to perform due to events beyond our reasonable control.

19.6 Language. These Terms are drafted in English, which is the governing version. Any translation is for convenience only.

20. Apple App Store additional terms

If you download the App from the Apple App Store, the following also applies:

These Terms are between you and Coileen only, not with Apple. Apple is not responsible for the App or its content.
Apple has no obligation to provide maintenance or support for the App.
If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation.
Coileen, not Apple, is responsible for addressing any claims relating to the App, including product liability, legal or regulatory non-compliance, and consumer protection claims.
Coileen, not Apple, is responsible for investigating and resolving any third-party claim that the App infringes intellectual property rights.
You confirm you are not located in a country subject to a US Government embargo or designated as a "terrorist supporting" country, and are not on any US Government prohibited-parties list.
Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

21. Google Play additional terms

If you download the App from Google Play, your use is also subject to the Google Play Terms of Service. Google is not a party to these Terms and is not responsible for the App.
