Terms of Use

01Agreement to these terms

These Terms of Use are a binding agreement between you and Healthy Hair Growth LLC ("HairChart", "we", "us"). They govern your use of the HairChart mobile and tablet applications, the provider dashboard, the API and myhairchart.com (together, the "Service").

By creating an account, installing the app, or using the Service, you accept these terms and our Privacy Policy, which forms part of this agreement. If you do not accept them, do not use the Service.

If you are agreeing on behalf of a salon, company or other organisation, you confirm you have authority to bind it, and "you" means that organisation.

02Definitions

03Eligibility

• You must be at least 18 years old.
• You must hold any licence, registration or certification your jurisdiction requires to provide hair or scalp services.
• You must not be barred from receiving the Service under applicable law or sanctions, and must not have had a HairChart account terminated for breach.
• HairChart is a professional tool. It is not offered for personal or consumer self-assessment.

04Your licence to use HairChart

Subject to these terms and to payment of the applicable fees, we grant you a limited, non-exclusive, non-transferable, revocable, non-sublicensable licence to install and use the Service for your internal business purposes.

You must not, and must not permit anyone else to:

• Copy, modify, translate or create derivative works of the Service.
• Reverse engineer, decompile or disassemble it, except where that restriction is prohibited by law.
• Rent, lease, resell, sublicense, or provide the Service as a service bureau to third parties.
• Remove or obscure any proprietary notice.
• Scrape, crawl, or use automated means to extract data, or access the Service to build a competing product.
• Circumvent usage limits, authentication, rate limits or security controls.

05Accounts, staff and devices

• Accounts are personal to each Professional. Do not share logins.
• You are responsible for everything done under your account and under the accounts of Professionals you authorise.
• Keep credentials confidential and tell us at [email protected] immediately if you suspect unauthorised access.
• Where the Service runs on a shared salon device, you are responsible for physical security of that device — passcode, screen lock, and removing access when a staff member leaves.
• You are responsible for your own internet connection, devices and any carrier charges.

06Client consent — your obligation

This is the most important obligation in this agreement.

You are the controller of Provider Data. We process it on your instructions. You warrant that you have, and will maintain, a lawful basis for every collection, use and disclosure you make through the Service, and that you will comply with all privacy, biometric, consumer protection and professional conduct laws that apply to you — including, where relevant, the Illinois Biometric Information Privacy Act, the Texas CUBI Act, the Washington My Health My Data Act and the CCPA as amended.

You must give each Client a clear explanation of what is captured, why, who may see it and how to withdraw consent, and you must honour a withdrawal promptly.

07Professional responsibility

HairChart supports your judgement. It does not replace it.

• Every service decision — what style to install, what tension to use, whether to decline a request, whether to refer — remains yours.
• You are responsible for the accuracy of what you enter, and for reviewing any analysis before acting on it or sharing it with a Client.
• You must not present HairChart output to a Client as a medical diagnosis, and must not use it to diagnose, treat, cure or prevent any condition.
• You must refer a Client for professional medical evaluation where their presentation warrants it.

08Acceptable use

You must not use the Service to:

• Upload images of anyone who has not consented, or images that are not scalp or hair captures taken for an Assessment.
• Upload sexual content, content involving minors other than a legitimate assessment with guardian consent, or any unlawful material.
• Impersonate another person or misrepresent your qualifications.
• Infringe anyone's intellectual property, privacy or publicity rights.
• Transmit malware, or interfere with or overload the Service.
• Access another Provider's data, or attempt to.

09AI-assisted analysis

The Service uses artificial intelligence to help analyse scalp images. You acknowledge that:

• AI output is probabilistic. It may be incomplete, inconsistent or wrong.
• Confidence indicators express the model's own estimate, not a guarantee of accuracy.
• Output quality depends on capture quality — lighting, focus and distance.
• Scores, statuses and trends are decision-support signals only, and carry no clinical meaning.
• We do not warrant that any analysis is accurate, complete or fit for a particular purpose, and we may change, retrain or replace the underlying models at any time.

10The Scalp & Hair Clinic Network

• Where available, you may submit a case for review by a participating trichology or dermatology provider, with the Client's explicit consent and never without it.
• Reviewing providers are independent practitioners. They are not our employees or agents, and we do not supervise, endorse or guarantee their services or opinions.
• We do not guarantee that review is available in your area, within any timeframe, or at all.
• Any relationship formed between a Client and a reviewing provider is between them. Their professional, licensing and record-keeping obligations are their own.
• Participation in the Clinic Network, and any right to display a Clinical Partner Salon seal, is granted at our discretion, may carry additional criteria, and may be withdrawn.

11Subscriptions and billing

Plans and fees

The Service is offered on subscription. Current plans, features and prices are shown at myhairchart.com or in the app at the point of purchase. Fees are exclusive of taxes unless stated; you are responsible for any applicable sales, use or value-added tax.

Automatic renewal

Subscriptions renew automatically at the end of each billing period at the then-current rate, until cancelled. Cancel at least 24 hours before the period ends to avoid renewal.

Where you bought it

• Apple App Store — billing, renewal and cancellation are managed by Apple in your Apple Account settings. Refunds are at Apple's discretion under its media services terms.
• Google Play — billing, renewal and cancellation are managed by Google in Play subscription settings. Refunds follow Google Play's refund policy.
• Direct from us — billed through [PAYMENT PROCESSOR]; cancel in your account settings or by writing to [email protected].

Trials, changes and non-payment

• A free trial, where offered, runs for 14 days and converts to a paid subscription unless cancelled before it ends.
• We may change prices with at least 30 days notice, effective at your next renewal. If you do not accept, cancel before then.
• Except where the law requires otherwise, fees are non-refundable and there are no refunds for partial periods or unused features.
• If payment fails we may suspend access until the balance is cleared.

12Your data and our data

You own your data

As between you and us, you own all Provider Data. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, transmit, process, display and back up that data solely to provide, secure and support the Service, and to comply with law.

What we may do with aggregates

We may create aggregated and de-identified data from use of the Service and use it to operate, analyse and improve our products. Such data cannot reasonably be used to identify you, your Provider or any Client, and we will not disclose it in a form that identifies anyone.

Export and deletion

You may export Provider Data at any time while your subscription is active. On termination you have 30 days to export; after that we may delete it in line with the Privacy Policy. Deletion is permanent.

Feedback

If you send us suggestions or feedback, we may use them without restriction, attribution or payment.

13Intellectual property

The Service, including its software, models, interfaces, zone methodology, scoring, designs, documentation and the HairChart name and logo, is owned by us and our licensors and is protected by intellectual property law. Nothing in these terms transfers any ownership to you. All rights not expressly granted are reserved.

You may not use our trade marks without prior written permission, except to identify that you use HairChart in your salon.

14Third-party services

The Service relies on third parties including cloud hosting, AI processing, payment processing and analytics, and may link to third-party sites or products. We are not responsible for third-party services, and your use of them is governed by their own terms. A third party's failure, outage or change may affect the Service.

15Not medical advice

HairChart is not a medical device and has not been evaluated, cleared or approved by any medical regulator. No content in the Service is medical advice, and no professional–patient relationship is created between you, your Clients and us.

16Disclaimers

Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you. Nothing here limits rights that cannot lawfully be limited, including consumer guarantees.

17Limitation of liability

These limits do not apply to liability that cannot be excluded by law, including death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or — where applicable — a party's breach of its confidentiality or data protection obligations.

You accept that the Service is decision support and that you bear responsibility for your professional decisions and their consequences.

18Indemnity

You will defend, indemnify and hold harmless HairChart, its officers, employees and agents from any claim, loss, liability, damage, cost or expense (including reasonable legal fees) arising out of or relating to:

• Your use of the Service, or use by any Professional you authorised.
• Provider Data, including any claim that you collected, used or disclosed it without a lawful basis or without Client consent.
• Any service you performed on a Client, and any advice you gave.
• Your breach of these terms or of any law.

19Suspension and termination

• By you — cancel at any time in your account settings or the relevant app store. Access continues to the end of the paid period.
• By us — we may suspend or terminate immediately if you breach these terms, if we are required to by law, if your use creates risk to Clients or to the Service, or if fees go unpaid. Where practical we will give notice and an opportunity to fix the problem.
• Convenience — either party may terminate on 30 days written notice. If we terminate for convenience we will refund any prepaid, unused fees.
• On termination — your licence ends, access stops, and the export window in section 12 begins. Sections 12–18 and 21–24 survive.

20Changes to the Service and these terms

We may add, change or discontinue features. Where a change materially reduces functionality you rely on, we will give reasonable notice.

We may amend these terms. We will post the updated version with a new effective date and, for material changes, notify you in the app or by email at least 30 days before they take effect. Continuing to use the Service after that date means you accept the change. If you do not accept, stop using the Service and cancel.

21Governing law and disputes

These terms are governed by the laws of the State of Minnesota, United States, without regard to conflict-of-laws rules. The UN Convention on Contracts for the International Sale of Goods does not apply.

Informal resolution first

Before starting any formal proceeding, write to [email protected] describing the dispute. Both parties will try in good faith to resolve it within 30 days.

Arbitration and class waiver

If you reside in a jurisdiction where a pre-dispute arbitration agreement or a class-action waiver is unenforceable, this arbitration section does not apply to you, and you keep the right to bring proceedings in the courts of your place of residence.

22Apple App Store terms

Where you obtained HairChart from the Apple App Store, the following apply and prevail over any conflicting provision:

1. This agreement is between you and Healthy Hair Growth LLC only, not with Apple. We, not Apple, are solely responsible for HairChart and its content.
2. Your licence to use HairChart is limited to a non-transferable licence to use it on any Apple-branded device you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
3. Apple has no obligation to furnish maintenance or support for HairChart.
4. If HairChart fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are our sole responsibility.
5. We, not Apple, are responsible for addressing any claim by you or a third party relating to HairChart, including product liability claims, failure to conform to legal or regulatory requirements, and claims under consumer protection or similar legislation, including in connection with HairChart's use of the HealthKit and HomeKit frameworks where applicable.
6. We, not Apple, are solely responsible for the investigation, defence, settlement and discharge of any third-party claim that HairChart or your use of it infringes that third party's intellectual property rights.
7. You represent that you are not located in a country subject to a US Government embargo or designated as "terrorist supporting", and are not on any US Government list of prohibited or restricted parties.
8. You must comply with any applicable third-party terms when using HairChart.
9. Apple and its subsidiaries are third-party beneficiaries of these terms, and upon your acceptance will have the right to enforce them against you as a third-party beneficiary.
10. Direct questions, support requests and complaints to [email protected], not to Apple.

23Google Play terms

Where you obtained HairChart from Google Play:

• This agreement is between you and Healthy Hair Growth LLC only, not with Google. Google is not responsible for HairChart or its content.
• Your use is also subject to the Google Play Terms of Service.
• Google provides no warranty and no support for HairChart.
• Subscriptions purchased through Google Play are managed, renewed and cancelled in your Google Play account, and refunds follow Google Play's refund policy.

24General

• Entire agreement — these terms and the Privacy Policy are the whole agreement between us on this subject and supersede anything earlier.
• Severability — if any provision is unenforceable, the rest stays in force and the provision is limited to the minimum extent necessary.
• No waiver — failure to enforce a provision is not a waiver of it.
• Assignment — you may not assign these terms without our written consent. We may assign them to an affiliate or in connection with a merger, acquisition or sale of assets.
• Notices — we may give notice by email to your registered address or by in-app message. Notices to us go to [email protected].
• Force majeure — neither party is liable for delay or failure caused by events beyond its reasonable control.
• No agency — nothing creates a partnership, joint venture, employment or agency relationship.
• Export — you will comply with applicable export control and sanctions laws.
