Terms of Use and Sale

1. Agreement and operator

These Terms of Use and Sale ("Terms") are a legally binding agreement between you and Volodymyr Kachmar, an individual based in Massachusetts, United States ("we," "us," "our," or the "Operator"), professionally known as Dr. Kachmar. They govern access to and use of the website located at drkachmar.me and any professional resources, forms, subscriptions, and digital educational products offered through it (collectively, the "Site").

By accessing or using the Site, or by purchasing a product offered through the Site, you agree to these Terms. If you do not agree, do not use the Site or purchase any product.

2. Site purpose and professional nature

The Site is a professional website relating to Dr. Kachmar's clinical, research, speaking, and educational activities, and it offers structured digital educational products intended for dental professionals and dental students under appropriate supervision. It is not a patient-facing clinical service, appointment channel, telehealth service, or medical-advice portal.

3. No dentist-patient relationship

Use of this Site, any Site form, any educational material, or any general communication with the Operator does not create a dentist-patient relationship and does not provide patient-specific diagnosis, treatment, or clinical advice.

Individuals seeking care for a specific dental condition must consult a qualified licensed clinician in their own jurisdiction.

4. Educational disclaimers and no guarantees

All materials are provided for professional education only. They do not replace patient- specific diagnosis, independent professional judgment, licensure, supervision requirements, manufacturer instructions for use, applicable standards, or local law and regulation.

We do not guarantee any clinical, aesthetic, financial, business, income, examination, continuing-education (CE) credit, licensure, or outcome result. No CE credit is granted unless a specific product page or agreement expressly says so. You are responsible for evaluating whether any technique, workflow, instrument selection, or approach described in the materials is appropriate to a particular clinical situation and permitted under applicable law in your jurisdiction.

5. Eligibility and user responsibility

You must be at least 18 years old to purchase a product, create an account, or submit forms intended for professionals. Certain resources and products are intended for dentists or for dental students working under appropriate supervision. By requesting or purchasing such a resource or product, you represent that you meet the applicable professional criteria and that use of the material is lawful in your jurisdiction.

6. Accounts and access

Where account-based access is used, you are responsible for keeping your credentials confidential, for all activity occurring under your access, and for promptly notifying us of any suspected unauthorized use. Sharing credentials is prohibited (see Section 12).

7. Products and programs

The following resources are currently offered through the Site:

• Digital Veneer Prep Checklist — a free professional resource delivered by email upon request.
• The Digital Veneer Playbook — an active paid digital educational product.
• The 8-Day Clinical Photography Protocol — an active paid digital educational product.

Digital Veneer Mastery and AI for Dentists are professional programs in development. They are not currently sold. Interest signups for these programs record your request to receive future updates about that specific program only.

8. Orders, checkout, taxes, and delivery

Purchases of paid digital products are processed through Stan Store, our current external checkout and delivery provider, under Stan Store's own terms and privacy policy. Placing an order constitutes an offer to purchase; the order is accepted only when we or the checkout provider confirm the order and delivery is initiated. We may refuse or cancel an order in cases including suspected fraud, pricing or description error, product unavailability, or violation of these Terms, in which case any amount charged is refunded.

Prices and currency for each active product are shown at the checkout at time of purchase. Applicable taxes, VAT, GST, or fees may be added and are determined by the checkout provider's configuration and applicable law. We do not receive or store complete payment-card data on drkachmar.me.

Digital products are delivered electronically, typically by access instructions and/or download links provided by the checkout provider after payment is confirmed. To access a digital product, you will need a compatible device, an internet connection, a current browser, and any software reasonably required for the format described at the product page or checkout. You are responsible for retaining personal copies of any files you download. We do not promise permanent or perpetual hosting of downloadable files unless the specific product page expressly says so.

9. Refunds, cancellations, and non-delivery

Unless a product page or checkout conspicuously states a different policy, sales of downloadable or immediately accessible digital content are final once access, download, or delivery has begun, except where applicable law requires otherwise or the digital content is not delivered or is materially defective.

The refund and cancellation policy disclosed at checkout before purchase forms part of the transaction. If a product is not delivered, delivered incompletely, materially defective, or if you were charged more than once for the same order, please contact us promptly for support and, where appropriate, a refund or corrective delivery.

Nothing in these Terms waives any statutory, non-waivable consumer rights that may apply to you under the law of your jurisdiction, including any mandatory right of withdrawal or warranty rights that cannot be excluded. We do not claim a universal statutory withdrawal waiver.

Support for purchases: contact support.

10. Chargebacks and payment disputes

If you have a concern about a charge, please contact us in good faith first via contact support so we can attempt to resolve it directly. This request does not waive any lawful right you have to dispute a charge with your card issuer or payment provider. Fraudulent chargebacks may result in loss of access to purchased products, suspension of accounts, and pursuit of amounts owed.

11. Professional events and engagements

Speaking, workshop, training, and private engagement terms — including fees, cancellation, recording, travel, participation, and confidentiality — are set out in the applicable proposal or registration agreement between the organizer or participant and the Operator. Those specific written terms control over these general Terms with respect to that engagement.

12. Intellectual property and license

All text, images, videos, workflows, frameworks, structured curricula, datasets, and other materials on the Site and in the digital educational products (the "Course Materials") are owned by the Operator or licensed to the Operator and are protected by copyright, trademark, and other intellectual-property laws.

License. Subject to your compliance with these Terms and payment in full where applicable, we grant you a limited, non-exclusive, non-transferable, non-sublicensable license, revocable upon a material breach of these Terms, to access and use the Course Materials solely for your own personal, individual professional education. Unless expressly authorized in writing, you may not:

• Resell, redistribute, sublicense, rent, lease, or lend the Course Materials.
• Share account credentials or access with any other person.
• Publicly upload, mirror, host, or share the Course Materials on file-sharing, torrent, or social platforms.
• Record, screen-capture, or re-transmit live sessions or Course Materials.
• Perform bulk copying, scraping, or automated extraction of Site content or Course Materials.
• Use the Course Materials to develop, market, or deliver a competing course, workshop, or paid teaching program.
• Create derivative works for commercial purposes.
• Remove or alter any copyright, credit, watermark, or attribution notice.
• Use, upload, or ingest the Course Materials, datasets, or protected content for training, fine-tuning, evaluation, or grounding of any artificial-intelligence or machine-learning system.

Group, clinic-wide, institutional, or team access is not implied by an individual purchase and requires a separate written license. Non-waivable statutory rights, including any mandatory fair-use, fair-dealing, or exception-and-limitation rights under applicable copyright law, are preserved.

13. Acceptable use and account security

You agree not to:

• Use the Site or Course Materials in violation of law or professional obligation.
• Interfere with, disrupt, probe, or gain unauthorized access to the Site, its accounts, or its infrastructure.
• Introduce malicious code, attempt to bypass rate limiting, or scrape at abusive rates.
• Misrepresent your identity or professional status to obtain resources intended for professionals.
• Use Site contact channels to send unsolicited commercial communications.

We may suspend or terminate access to the Site, an account, or a purchased product for material or repeated breach of these Terms. We will apply this remedy proportionately and in a manner consistent with applicable consumer-protection law.

14. User submissions and patient data

Do not submit patient records, radiographs, clinical photographs, protected health information, or any other sensitive clinical or patient data through Site forms.

Submissions should be limited to what is necessary for the professional inquiry or resource request. You are responsible for ensuring that any information you submit through the Site is lawful to share and does not breach any confidentiality or privacy obligation.

15. Third-party services and links

The Site uses third-party services (including Supabase, Resend, Mailchimp, Plausible, Lovable hosting, and Stan Store) and links to external destinations. Those services and destinations are governed by their own terms and privacy policies. We are not responsible for the availability, content, or practices of independent third-party services, except where applicable law imposes responsibility that cannot be disclaimed.

16. Privacy

Our Privacy Policy describes how we collect, use, and safeguard personal information and is incorporated into these Terms by reference.

17. Warranty disclaimers

To the maximum extent permitted by applicable law, the Site and Course Materials are provided on an "as is" and "as available" basis, without warranties of any kind, whether express, implied, statutory, or otherwise, including implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranty arising out of course of dealing or usage of trade. We do not warrant that the Site or Course Materials will be uninterrupted, always current, complete, error-free, or fit for any particular clinical or business decision. Some jurisdictions do not allow the exclusion of certain warranties; those exclusions apply to you only to the extent permitted by applicable law.

18. Limitation of liability

To the maximum extent permitted by applicable law, the Operator will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, professional reputation, patient outcomes, or business, arising out of or relating to the Site, the Course Materials, or these Terms, whether based on contract, tort (including negligence), statute, or any other legal theory, and whether or not the Operator has been advised of the possibility of such damages.

Aggregate cap. If you have paid the Operator for the specific product or service giving rise to the claim during the twelve (12) months preceding the event giving rise to the claim, the Operator's total aggregate liability arising out of or relating to the Site, the Course Materials, or these Terms will not exceed the amount you actually paid for that specific product or service during that period. If you have not paid the Operator any amount during that period, the aggregate cap is one hundred U.S. dollars (USD $100).

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited, including liability for fraud, willful misconduct, gross negligence where applicable law prohibits its exclusion, death or personal injury caused by negligence where applicable law prohibits its exclusion, or any non-waivable consumer-protection rights.

19. Indemnification

To the maximum extent permitted by applicable law, you agree to indemnify and hold the Operator harmless from and against third-party claims, damages, liabilities, costs, and reasonable attorneys' fees to the extent directly arising out of (a) your unlawful or willful misuse of the Site or Course Materials, (b) your unauthorized redistribution of the Course Materials or infringement of the Operator's or a third party's intellectual-property rights, or (c) your knowing submission of patient or third-party data through the Site without lawful authority. The Operator will promptly notify you in writing of any such claim, tender its defense, and reasonably cooperate at your expense. This indemnity does not apply to any portion of a claim caused by the Operator's own acts or omissions, fraud, willful misconduct, or gross negligence, and it does not limit or override any non-waivable consumer-protection rights that apply to you under mandatory law.

20. Governing law and disputes

Governing law. These Terms are governed by the laws of the Commonwealth of Massachusetts, United States, without regard to its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Informal resolution. Before commencing a formal proceeding, the parties agree to attempt to resolve any dispute informally by sending a written notice via contact support describing the dispute and the relief sought, and to negotiate in good faith for at least thirty (30) days after the notice is delivered.

Forum. If the dispute is not resolved informally, the parties submit to the exclusive jurisdiction of the state and federal courts located in the Commonwealth of Massachusetts, United States, and waive any objection to venue in those courts. This does not deprive you of access to your local small-claims court where applicable law permits, and it does not deprive you of any mandatory consumer forum or mandatory consumer-protection law of your country or state of residence that applies notwithstanding this choice of forum.

These Terms do not require binding arbitration and do not include a class-action waiver.

21. Changes to these Terms

We may update these Terms from time to time. Updates apply prospectively from the stated effective date. Material changes will be indicated by updating the effective date at the top of these Terms and, where appropriate, by more prominent notice on the Site. The Terms accepted at the time of a specific purchase continue to apply to that transaction unless applicable law or a mutually agreed update requires otherwise.

22. General provisions

• Entire agreement. These Terms, together with the Privacy Policy and any product- or event-specific written terms, constitute the entire agreement between you and the Operator regarding the Site and any purchase.
• Priority. Specific written product or event terms accepted at purchase or registration control over these general Terms with respect to that transaction or engagement.
• Severability. If any provision of these Terms is held unenforceable, the remaining provisions will remain in effect, and the unenforceable provision will be enforced to the maximum extent permitted by law.
• Waiver. Failure to enforce any provision is not a waiver of the right to enforce it later.
• Assignment. You may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets, or to an affiliate, with appropriate safeguards.
• Force majeure. Neither party is liable for delay or failure to perform caused by events beyond its reasonable control.
• Electronic communications. You consent to receive communications from us electronically, including by email and through the Site, and agree that electronic communications satisfy any legal requirement that a communication be in writing, to the extent permitted by applicable law.
• Headings. Section headings are for convenience only and do not affect interpretation.
