1. Agreement
These Terms form a binding agreement between you (“Participant“) and DrEthan AI Aesthetics (“we“, “us“, “the Provider“), operated by Wen Hsien Ethan Huang, in respect of all courses, recorded video content, written and visual materials, and physical training aids sold through drethan.ai.
By completing checkout you confirm that you have read, understood, and agreed to these Terms.
2. Eligibility
2.1 Courses are offered exclusively to currently licensed medical practitioners and, where expressly stated on the product page, to other regulated healthcare professionals whose scope of practice includes the procedures taught.
2.2 You must submit valid proof of licensure at enrolment. Access is granted only after verification.
2.3 If verification fails, your order is cancelled and refunded in full.
2.4 If you submit false, altered, or another person’s credentials, we may terminate all access immediately without refund and pursue any remedies available to us.
3. Licence Granted
3.1 You receive a personal, non-exclusive, non-transferable, non-sublicensable licence to view the course content for your own professional education. You do not acquire ownership of the content.
3.2 All copyright, database rights, trade marks, and other intellectual property in the courses โ including video, slides, illustrations, case material, protocols, and any accompanying models or templates โ remain the property of the Provider or its licensors.
3.3 Unless the product page states otherwise, access runs for twenty-four (24) months from the date access is granted.
3.4 We may update, revise, or withdraw content where required by changes in clinical evidence, regulation, or licensing. Where material is withdrawn permanently and without replacement during your access period, contact us and we will discuss a fair remedy.
4. Restrictions
You must not, and must not permit any other person to:
4.1 Record, screen-capture, screen-record, film, download, or otherwise copy the video content by any means.
4.2 Reproduce, distribute, publish, upload, transmit, or make available any part of the course โ including video, slides, transcripts, images, or written materials โ on any website, cloud storage service, messaging group, social platform, or other channel.
4.3 Share, lend, sell, rent, or otherwise disclose your account credentials or any access link to any third party; permit any other person to view the content using your access; or use a single account for more than one individual.
4.4 Use the content to deliver your own training, workshops, courses, or internal teaching materials, whether commercially or otherwise.
4.5 Translate, adapt, re-edit, or create derivative works from the content, or remove, obscure, or circumvent any watermark or technical protection measure.
4.6 Submit any part of the content to any artificial intelligence system for training, fine-tuning, indexing, or retrieval, or otherwise use it as input to any machine learning process.
5. Watermarking and Traceability
5.1 Course video and downloadable materials carry a personalised identifying watermark derived from your enrolment details, which may include your name and a partial licence number.
5.2 You consent to this processing. Its sole purpose is to deter and trace unauthorised distribution. See clause 12.
5.3 Where leaked material is identified, we may use the watermark to establish its source and act under clause 8.
6. Account Security
6.1 Your account is for your sole use. Concurrent access is limited to one device at a time.
6.2 You are responsible for keeping your credentials secure. Where content is disclosed because you failed to do so, clause 8 applies.
6.3 We may suspend an account showing anomalous access patterns โ such as logins from multiple distant locations in a short period โ and ask you to account for them before restoring access.
7. Cancellation and Refunds
7.1 โ Consumers in the EU, UK, and other jurisdictions with a statutory withdrawal right. You normally have 14 days to withdraw from a purchase of digital content. However, where you have expressly requested that access begin immediately and have acknowledged that you thereby lose the right of withdrawal, that right no longer applies once access has been granted. You give that request and acknowledgment by ticking the box at checkout.
7.2 If you do not give that consent, access begins after the 14-day period and you may cancel within it for a full refund.
7.3 Outside the circumstances in 7.1โ7.2, and except where a mandatory consumer law provides otherwise, digital course access is non-refundable once granted.
7.4 Full refunds are given where licence verification fails, where we are unable to deliver the course, or where required by applicable law.
7.5 Physical training aids are governed by the shipping and returns policy on the relevant product page.
8. Breach and Remedies
8.1 Where you breach clause 4, we may terminate your access immediately and without refund.
8.2 You acknowledge that unauthorised distribution causes loss that is real but difficult to quantify โ lost sales, devalued licensing, and reputational harm within a professional community. The parties therefore agree that a payment of USD 10,000 per act of unauthorised distribution represents a genuine pre-estimate of that loss and is not a penalty.
8.3 Clause 8.2 does not limit our right to seek injunctive relief, to recover actual losses exceeding that sum, or to pursue any other remedy available at law.
8.4 We may notify a Participant’s licensing body or employing institution of a substantiated breach where the conduct engages professional standards.
9. Laboratory Training Aids
9.1 Resin tissue-simulation models, anodised aluminium tactile calibration tools, and any other physical items sold by us are laboratory demonstration aids for ex vivo training only.
9.2 They are not medical devices. They carry no FDA clearance, CE mark, UKCA mark, or equivalent regulatory approval, and are not to be used on humans or animals, or in any clinical setting.
9.3 Use contrary to clause 9.2 is entirely at your own risk and responsibility.
10. Educational Purpose and Professional Responsibility
10.1 All content is provided for professional education and academic exchange. It does not constitute clinical advice in respect of any individual patient, and no clinical outcome is warranted.
10.2 You remain solely responsible for every clinical decision and procedure you perform. You must exercise independent professional judgment and comply with the law, regulatory requirements, and institutional protocols applicable where you practise.
10.3 Approvals for injectables, devices, and techniques differ between jurisdictions. You are responsible for confirming that anything taught is lawful in your own.
10.4 Nothing in the courses creates a doctorโpatient relationship, a supervisory relationship, or a referral relationship between us and you or your patients.
11. Limitation of Liability
11.1 Nothing in these Terms excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded.
11.2 Subject to 11.1, we are not liable for indirect or consequential loss, loss of profit, loss of business, or loss of professional reputation.
11.3 Subject to 11.1, our total liability in connection with any course is limited to the amount you paid for it.
12. Data Protection
12.1 We process your personal data to verify your licence, provide and secure access, generate watermarks, and handle support. The legal basis is performance of this contract and our legitimate interest in protecting our intellectual property.
12.2 Data processed includes your name, email address, licence details, watermark identifier, and access logs.
12.3 We retain enrolment and access records for the duration of your access and for a reasonable period afterwards for accounting and enforcement purposes.
12.4 Where the GDPR or UK GDPR applies to you, you have rights of access, rectification, erasure, restriction, portability, and objection, and the right to complain to your supervisory authority. Requests: [email protected].
12.5 We do not sell your personal data. We share it only with service providers acting on our instructions (payment processing, video hosting, email delivery), and where required by law.
13. Governing Law and Disputes
13.1 These Terms are governed by the laws of Taiwan (Republic of China), and the Taipei District Court has jurisdiction.
13.2 Clause 13.1 does not deprive you of the protection of mandatory consumer law in your country of residence, or of the right to bring proceedings in your local courts where that law so provides.
13.3 Before commencing proceedings, both parties will attempt in good faith to resolve any dispute by direct discussion for 30 days.
