Terms of Service

1. Who we are and how these Terms apply

These Terms of Service (the "Terms") govern the use of the DentVIS software and the related cloud services (together the "Service") provided by Dentmall s.r.o., Company ID (IČO): 09041036, VAT ID (DIČ): CZ09041036, with its registered office at Pivovarská 214/4, 370 01 České Budějovice, Czech Republic, registered with the Regional Court in České Budějovice, file no. C 29761 ("we", "us", the "Provider"). Contact: dentmall@email.cz.

The Terms form an agreement between the Provider and the natural or legal person using the Service (the "User", "you"). You accept the Terms by ticking the acceptance box when creating your DentVIS account, by confirming them in the application when prompted, or by using the Service, whichever occurs first. If you accept the Terms on behalf of a company or practice, you confirm that you are authorised to bind that entity.

Please read the Terms carefully. They contain, in particular, important provisions on the permitted purpose of the software (Sections 3 and 4), your responsibility for clinical decisions and manufactured appliances (Sections 4, 15 and 16), and limitations of our liability (Section 16).

We process personal data as described in our Privacy Policy. Refunds are governed by our Refund Policy. Both documents form part of your agreement with us.

2. The Service

DentVIS is standalone dental CAD software for the visualization and editing of 3D dental models — including tooth segmentation, preparation of a Virtual Setup (a digital rearrangement of tooth positions) and export of working models — available as native applications for macOS, Windows and iPadOS, together with a web dashboard at app.dentvis.com and optional cloud synchronization of case data (each part of the "Service").

The scanner or other equipment used to acquire 3D scans is not part of the Service. The Service requires an internet connection for account sign-in, licensing and optional cloud synchronization; model editing itself runs locally on your device.

A "case" is a set of data you create in the Service (imported scans, segmentation, Virtual Setup, labels and related content). "Customer Data" means all data you upload to or create in the Service.

3. Medical device status and intended purpose

DentVIS is a Class I medical device pursuant to Regulation (EU) 2017/745 on medical devices (MDR), CE marked and registered in EUDAMED. Details, including identification of the EU Declaration of Conformity (a copy is available from us on request), are provided on our regulatory information page.

The intended purpose of the software is the visualization and editing of 3D dental models and the preparation of digital working models (Virtual Setup) as a basis for the design and manufacture of orthodontic and prosthetic appliances. The software is intended to be used exclusively by qualified dental professionals (dentists, orthodontists, dental technicians) trained in digital dental workflows. It is not intended for use by laypersons.

The software does not provide any diagnostic, therapeutic or clinical recommendations. It is a passive CAD visualization and editing tool: every repositioning of teeth and every other editing of a model is performed manually by you — the software does not automatically analyse tooth positions and does not propose tooth movements. Automatic processing is limited to technical mesh optimization and repair on import, the result of which you are required to verify (see the Instructions for Use). Measurement values displayed by the software are for reference only, are not clinically calibrated and must not be used as a basis for clinical decisions.

The electronic Instructions for Use are an integral part of the device. You are obliged to read them before first use and to follow the warnings and precautions they contain.

4. Prohibited uses — no clinical or therapeutic use

The Provider excludes and expressly prohibits the use of the Service in any way in which the Service or its outputs would be used to:

• diagnose, prevent, control, monitor, predict, prognosticate, treat or alleviate a disease or an injury, or to alleviate or compensate for an injury or disability;
• examine, replace, modify or otherwise adjust an anatomical structure or a physiological or pathological process or state;
• provide diagnostic or therapeutic recommendations of any kind;
• make or support clinical decisions as the sole or primary basis for such decisions; or
• serve directly as a medical device or as an accessory to a medical device.

Outputs of the Service (including exported STL, VIS or CSV files and 3D-printed models produced from them) are digital working models only. They are not a medical device, they have no direct therapeutic or diagnostic effect and they are not directly usable in the mouth of any person. Any design, manufacture or application of an orthodontic or prosthetic appliance on the basis of outputs of the Service may be carried out only by a person or entity holding the education and authorisations required by applicable law, with full professional care, and after independent verification of the outputs.

If you use the Service or its outputs in the provision of health services or otherwise in connection with the care of any person, you do so exclusively at your own risk and under your own professional responsibility. You — as the qualified professional — remain solely responsible for the review, verification and approval of every output of the Service, for every clinical decision, and for every appliance manufactured on the basis of such outputs. The Provider bears no responsibility toward you or toward any third party (including any person to whom care is provided) for any use of the Service or its outputs contrary to this Section.

5. Your account

You must create a DentVIS account to use the Service. You must provide accurate and complete information when registering and keep it up to date. You are responsible for maintaining the confidentiality of your credentials and for all activity under your account; we recommend using a unique password. Notify us without undue delay at dentmall@email.cz if you suspect unauthorised use of your account.

The Service is intended for business use by dental professionals and their staff. By registering you declare that you have full legal capacity and are at least 18 years old.

You are responsible for ensuring that the members of your staff and any other persons who use the Service under your licence (including assistant seats) are familiar with these Terms and comply with them; their acts and omissions in the Service are attributed to you.

The Service is offered for registration in the member states of the European Union. Availability of the Service, or of certain content or functions, may be restricted in certain countries; the Provider bears no responsibility for such restrictions and does not warrant that the Service complies with the laws of countries for which it is not offered. By registering you also represent that you are not subject to sanctions adopted by the European Union or the United Nations that would prohibit the provision of the Service to you.

We keep records of your acceptance of these Terms and of the other documents listed in Section 19 (including the accepted version, timestamp and technical identifiers) as evidence of the conclusion of the agreement.

6. Licence and seats

Subject to payment of the applicable fees, we grant you a personal, non-exclusive, non-transferable licence, without the right to sublicense, to use the Service for your own internal business purposes for the duration of your subscription and within the limits of your plan. You do not acquire any ownership of the software or any other intellectual property rights.

The scope of the licence is defined by seats, as described on our pricing page: an editor seat is bound to a specific device and unlocks the complete workflow (it can be transferred to another device once per month via the dashboard); assistant seats are taken dynamically by other signed-in devices; opening and viewing cases is possible on any signed-in device without a seat. The number of editor and assistant seats included depends on your plan and add-ons.

You may not rent, lease, lend, sell, redistribute or sublicense the Service, share account credentials beyond the seats included in your plan, or circumvent seat, licensing or other technical restrictions of the Service.

7. Subscriptions, prices and payment

The Service is provided under subscription plans described on our pricing page. Unless stated otherwise, prices are exclusive of VAT; applicable taxes are shown at checkout.

Orders are processed by our merchant of record, Paddle.com Market Ltd ("Paddle"), which handles the checkout, payment, invoicing, applicable taxes and customer billing support. By making a purchase you also agree to Paddle's terms. We do not receive or store your full payment card details.

Subscriptions renew automatically at the end of each billing period (monthly or yearly) until cancelled. You can cancel at any time with effect from the end of the current billing period — you keep access until then. Refunds are governed by our Refund Policy.

We may change subscription prices. Price changes will be announced in advance and take effect from the next billing period after the notice; if you do not agree with a price change, you may cancel your subscription before it takes effect.

We may make the provision or continuation of the Service conditional on payment of the applicable fees. Promotional codes and vouchers are subject to the conditions under which they are issued, are not redeemable for cash and may be limited in time or scope.

8. Free trial

Where a free trial is offered, it is limited in time (currently 14 days) and in functionality (in particular, the trial works locally on your device and does not include cloud synchronization or model export). No payment details are required for the trial.

The trial is intended to let you evaluate the Service. We may modify, limit or withdraw trial availability at any time; one trial is available per customer unless we state otherwise.

9. Customer Data

You retain all rights to your Customer Data. We do not acquire any ownership of it; you grant us only the non-exclusive right to host, store, transmit and otherwise process Customer Data to the extent necessary to provide the Service (including cloud synchronization and sharing functions you invoke), as described in our Privacy Policy.

You are solely responsible for the content, accuracy and lawfulness of your Customer Data, for having all rights and permissions necessary to use it within the Service, and for the consequences of sharing it. If you generate a share link for a case, anyone in possession of the link can view the shared visualization until the link expires (share links expire automatically after a limited period); you are responsible for whom you provide the link to. Before generating a share link, verify that the case does not contain any data identifying the person to whom the model belongs (Section 10).

Your device is the primary storage of your data; the cloud service is a synchronization layer, not a backup service. The Provider does not guarantee the preservation of data in the cloud service and does not provide data backup as a service. You are responsible for regularly backing up your Customer Data (including local .vis files and exports). Cloud-stored case data is further subject to automatic archiving and deletion after longer periods of inactivity, as described in the Privacy Policy; deletion after the notified period is irreversible.

For a reasonable period after termination of your subscription or account you may request an export of your cloud-stored Customer Data at dentmall@email.cz; after that period the data is deleted.

10. Personal data in Customer Data — roles under the GDPR

The Service is designed to be used without personal data identifying the persons to whom the dental models belong. Cases are identified by a case label of your choosing. You must not enter names, birth numbers or other data identifying the persons to whom the dental models belong into case labels, notes or other fields of the Service, and you must not upload photographs or documents identifying such persons (in particular photographs showing a person's face or other uniquely identifying features). Use neutral case identifiers (e.g. your internal case numbers). By uploading Customer Data you represent and warrant, on each upload, that it does not contain any such identifying data.

Data that you process solely locally on your device is not transmitted to us. With respect to such data we act neither as a controller nor as a processor within the meaning of the GDPR; the software is a mere tool under your exclusive control, and you are solely responsible for the protection of such data, including the security of your devices and access control at your practice.

To the extent Customer Data that you synchronize to the cloud service or otherwise make available to us contains personal data of third parties — whether entered in breach of the first paragraph of this Section, or because a 3D dental model or other case content can, in your hands, be related to an identifiable person even though the case carries a neutral label — you act as the data controller of such data, and the Provider processes it strictly on your behalf as your processor within the meaning of Article 28 GDPR, solely to provide the Service. To the extent such processing occurs, the data processing terms set out below form a binding part of these Terms and constitute the contract required by Article 28(3) GDPR; a standalone signed copy is available on request at dentmall@email.cz. You are responsible for having a lawful basis for such processing (including, where the data constitutes data concerning health, satisfying one of the conditions of Article 9(2) GDPR), for fulfilling your information obligations, and for the admissibility of such data in the Service; you will indemnify the Provider in accordance with Section 17 for any consequences of a breach of this Section.

Data processing terms. Subject matter and duration: processing of Customer Data for the duration of the agreement. Nature and purpose: hosting, storage, synchronization, sharing invoked by you, and related technical support. Categories of data subjects and data: the persons to whom the dental models belong, and the data contained in your cases. Our obligations as processor: we process such data only on your documented instructions (including with regard to any transfer of such data to a third country), which are constituted by the agreement — including your standing instruction to carry out the remediation measures set out below — and by your use of the Service functions, and we will immediately inform you if, in our opinion, an instruction infringes the GDPR or other data protection provisions of Union or Member State law; we ensure that persons authorised to process the data are bound by confidentiality; we implement the technical and organizational measures described in the Privacy Policy; we engage only the sub-processors listed in the Privacy Policy, impose on them in substance the same data protection obligations as those set out in these terms, and will inform you of intended changes, to which you may object on legitimate grounds; taking into account the nature of the processing, we assist you with data subject requests and with your obligations under Articles 32 to 36 GDPR; we notify you without undue delay after becoming aware of a personal data breach concerning such data; upon termination we delete the data in accordance with the retention rules in the Privacy Policy, after you have had the opportunity to request an export of your cloud-stored Customer Data under Section 9 (deletion or return, at your choice), unless law requires further storage; and we make available the information necessary to demonstrate compliance with Article 28 GDPR and allow for and contribute to audits conducted by you or an auditor mandated by you, subject to reasonable notice and confidentiality; audits are conducted at your expense and no more than once per calendar year, unless a supervisory authority requires otherwise or a personal data breach concerning your data has occurred.

We do not monitor the content of Customer Data and assume no obligation to review it. If we become aware that Customer Data contains personal data in breach of this Section, we may request that you remedy the situation without undue delay. For that case you give us, by accepting these Terms, a prior documented instruction under the data processing terms above, entitling us — without liability for any resulting unavailability — to remove or replace the identifying data concerned (for example, to replace a case label with a neutral identifier), to suspend synchronization or sharing of the affected case or, if you fail to remedy the breach, to delete the data concerned.

If a data subject contacts us directly with a request concerning personal data contained in Customer Data, we will refer the request to you as the controller and inform you of it; responding to such requests is your responsibility. You remain responsible for all controller obligations under the GDPR in relation to such data, including records of processing activities, any required data protection impact assessments, and notifications of personal data breaches arising in your sphere.

The Service is not intended for the keeping of health documentation or patient records within the meaning of the healthcare law applicable to you, and must not be used as the sole or primary storage of documentation that you are required by law to keep. You keep such documentation in your own systems; the Service processes only the working data described in Section 2.

When you contact support, do not provide logs, case files, photographs or screen recordings containing personal data unless it is necessary; where possible, remove or anonymize personal data first. If you nonetheless provide materials containing personal data of the persons to whom the dental models belong, we process them solely to handle your support request, as part of the processing described in this Section; personal data relating to you as the account holder is processed as described in the Privacy Policy.

11. Acceptable use

You must not misuse the Service. In particular, you must not:

• reverse engineer, decompile, disassemble or otherwise attempt to derive the source code of the software or any part of it, except to the extent expressly permitted by mandatory law; nor copy, modify, translate or create derivative works of the software;
• interfere with the Service, its security elements or its operation, attempt to gain unauthorised access to the Service, other users' data or our systems, or probe, scan or test their vulnerability without our written consent;
• use the Service in violation of applicable law, including healthcare, medical device, data protection and export control law, or for any illegal, fraudulent or manipulative activity;
• upload content that you are not authorised to use or that infringes the rights of third parties or applicable law; content that is inappropriate, offensive, misleading or otherwise harmful; personal, private or confidential information of other persons without a lawful basis; or malicious code;
• impersonate another person or entity, send spam or unsolicited commercial communications through the Service, or request personal data from minors;
• use the Service to develop a competing product, or access it for benchmarking purposes without our written consent.

You acknowledge that use of, or access to, the Service may be restricted, suspended or terminated if your conduct is not in accordance with these Terms or applicable law (Section 12).

12. Changes to the Service; suspension

We continuously develop the Service. We may expand, change or remove functionality, deploy new versions and modules, and change the technical means of providing the Service. Material changes will be announced through the Service or on our website. Cases saved with a newer version of the software cannot be opened by older versions; we may require an update of the application (including a minimum supported version) for security or compatibility reasons. Features marked as beta, preview or experimental are provided for evaluation only, may be changed or withdrawn at any time and may not work reliably; do not rely on them for production work.

We are entitled to suspend or restrict the provision of the Service, in whole or in part, in particular: (a) to implement measures or decisions of public authorities; (b) due to technical or operational defects or security incidents; (c) for operational maintenance, repairs or deployment of new versions; or (d) on reasonable suspicion that you or a third party are misusing the Service or using it in violation of these Terms or applicable law, or where damage to third parties occurs or is imminent.

We may ask you to verify your identity or provide additional identification data or documents where required by law, in particular by Act No. 253/2008 Coll., on measures against the legalisation of proceeds of crime and the financing of terrorism. You are obliged to comply with such a request without undue delay.

In connection with the Service we may send you service notifications, administrative messages and other information relating to your account and licence. We may also display or send information about our products and services within the Service, including announcements, links and offers.

13. Availability

We provide the Service with professional care corresponding to the given field, but we do not warrant that the Service will be available without interruption or error-free. We are not responsible for the quality or availability of your internet connection or of services provided by third parties (including app stores and payment services), nor for restrictions resulting from your device or operating system.

We are not liable for any delay or failure to perform caused by circumstances beyond our reasonable control (force majeure), including outages of power or telecommunication networks, failures of third-party services, cyber-attacks, acts of public authorities, natural disasters or other extraordinary events. Our obligations are suspended for the duration of such circumstances.

14. Intellectual property

The software, the Service, and all related intellectual property rights (including trademarks, logos, design and documentation) remain the property of the Provider or its licensors. The software is protected as an author's work under Act No. 121/2000 Coll., the Copyright Act, and international treaties. These Terms do not grant you any rights other than the licence expressly set out in Section 6.

You may not use the Provider's trademarks, trade names or logos without prior written consent in a way that could create uncertainty as to who their owner or authorised user is.

If you provide us with feedback, suggestions or ideas concerning the Service, we may use them without restriction and without compensation; this does not apply to your Customer Data.

The Service may display content that is not owned by the Provider; responsibility for such content lies with the entity that publishes it.

15. Warranties

Except as expressly stated in these Terms or required by mandatory law, the Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose or non-infringement. To the extent permitted by law, the Provider disclaims all warranties and liability for defects arising from law.

We do not warrant that the Service will meet your requirements, that errors in the functioning of the Service will be corrected, or any deadline for corrections. We do not warrant results obtained by using the Service; responsibility for the interpretation and use of outputs of the Service rests with you (Sections 3 and 4).

16. Limitation of liability

All risks arising from the use of the Service — including the use of its outputs for the manufacture of appliances and any clinical use contrary to Section 4 — are borne exclusively by you. The Provider is, to the maximum extent permitted by law, not liable in particular:

• for the content and accuracy of data you enter into the Service, or for mistakes or damage caused by you providing or allowing access to your data or account to another person;
• for loss, corruption or unavailability of data (Section 9 — your device is the primary storage and you are responsible for backups);
• for damage caused by interruption of operation, technical failure, maintenance, deployment of new versions, or suspension or termination of the Service;
• for damage or other harm caused by the use of the Service or its outputs in violation of these Terms, whether in relation to you or to third parties;
• for lost profits, loss of revenue, financial losses, loss of business opportunity, or any indirect, special, incidental or consequential damage, or damage that could not reasonably have been foreseen.

If, notwithstanding the above, the Provider is liable to you for any claim arising out of or in connection with the agreement or the Service that has not been effectively excluded, the aggregate liability of the Provider for all claims together is limited to the amount you paid for the Service in the 12 months preceding the event giving rise to the claim.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law (in particular liability for damage caused intentionally or by gross negligence, or for harm caused to a person's natural rights). If you are a consumer, nothing in these Terms limits your mandatory statutory rights.

This Section applies not only to the Provider itself but also to its directors, managers, employees, agents, representatives and suppliers.

17. Indemnification

If you use the Service in violation of these Terms — in particular in violation of Section 4 (prohibited clinical use), Section 10 (personal data of third parties) or Section 11 (acceptable use) — and a third party (including any public authority) raises a claim against the Provider in connection with such use, you undertake to indemnify and hold the Provider harmless: you will reimburse the Provider for all damage, costs and expenses incurred (including reasonable costs of legal representation and any fines or penalties imposed) and provide the Provider with all assistance reasonably required to defend against such a claim. This does not apply to the extent the claim was caused by the Provider's own breach of these Terms. If you are a consumer, this Section applies only to the extent permitted by mandatory consumer protection law.

18. Term and termination

The agreement is concluded for an indefinite period. You may terminate it at any time by cancelling your subscription (with effect from the end of the paid period) and deleting your account. Uninstalling the application alone does not terminate a paid subscription.

We may terminate the agreement or your access to the Service with immediate effect in case of a material breach of these Terms (in particular Sections 4, 10 and 11), or with reasonable prior notice if we discontinue the Service; in the latter case we will endeavour to respect the rights of users with a paid subscription for the duration of the period already paid.

After termination, Section 9 (export window and deletion of cloud data) applies. Provisions which by their nature are intended to survive termination — in particular Sections 4, 10 (for as long as we hold Customer Data), 14 to 17 and 21 — survive.

19. Changes to these Terms

We may update these Terms, for example due to changes in legislation, in the Service or in our business model. We will announce material changes in advance through the Service, the dashboard or by e-mail, and the new version may be presented to you for acceptance in the application or dashboard. If you do not accept the new version, we may terminate the agreement and disable further use of the Service; you may also cancel your subscription before the new version takes effect.

The current version of the Terms is always available at www.dentvis.com/terms. When a subscription is renewed, the version of the Terms effective on the renewal date applies.

By accepting these Terms you also confirm that you have read the Privacy Policy, the Refund Policy and the Instructions for Use.

20. Consumer information

The Service is intended for professional business use. If you nevertheless conclude the agreement as a consumer (a natural person acting outside the scope of their business), the mandatory provisions of consumer protection law apply, and any provision of these Terms incompatible with them does not apply to you.

If you are a consumer, you have the right to withdraw from the agreement without giving a reason within 14 days of its conclusion. You may withdraw by sending an unequivocal statement to dentmall@email.cz or by post to Dentmall s.r.o., Pivovarská 214/4, 370 01 České Budějovice, Czech Republic; to meet the deadline it is sufficient to dispatch the withdrawal before the 14-day period expires. You may use the model withdrawal form at the end of this Section, but you are not obliged to. We will refund all payments received from you without undue delay, at the latest within 14 days of withdrawal, using the same means of payment.

Where the subject of the agreement is the supply of digital content not on a tangible medium, your right of withdrawal is extinguished if you have given your prior express consent to performance beginning before the end of the withdrawal period, you have acknowledged that you thereby lose the right of withdrawal, and we have provided you with confirmation of the agreement. Where the subject is a digital service provided over time and you have requested that performance begin during the withdrawal period, you may still withdraw within the period, but you must pay a proportionate part of the price for the performance provided up to the withdrawal. Our voluntary 14-day money-back guarantee applies independently of, and in addition to, these statutory rights.

As a consumer you also have statutory rights arising from defective performance of digital content and digital services under Sections 1914 et seq. and 2389a et seq. of Act No. 89/2012 Coll., the Civil Code (including the right to have defects remedied, to a reasonable price reduction, or to withdraw from the agreement in the cases provided by law). Complaints can be raised at dentmall@email.cz; we will confirm receipt and inform you of the outcome. Nothing in Section 15 (Warranties) limits these rights.

Disputes with consumers that could not be settled directly can be resolved out of court. The competent body for out-of-court settlement of consumer disputes is the Czech Trade Inspection Authority (Česká obchodní inspekce, www.coi.cz; details on the procedure at adr.coi.cz).

Model withdrawal form (complete and send only if you wish to withdraw from the agreement): Addressee: Dentmall s.r.o., Pivovarská 214/4, 370 01 České Budějovice, Czech Republic, e-mail: dentmall@email.cz. — I hereby give notice that I withdraw from the agreement on the provision of the DentVIS service. — Account e-mail / date of conclusion of the agreement: … — Name of the consumer: … — Address of the consumer: … — Date: … — Signature of the consumer (only if this form is sent on paper).

21. Governing law, jurisdiction and final provisions

These Terms and the agreement are governed by the laws of the Czech Republic, in particular Act No. 89/2012 Coll., the Civil Code; the application of the UN Convention on Contracts for the International Sale of Goods is excluded. This choice of law does not deprive consumers of the protection afforded by mandatory provisions of the law of their country of habitual residence.

For users who are not consumers, disputes will be resolved by the courts of the Czech Republic, and the court having jurisdiction at the Provider's registered office is agreed as the competent court. If you are a consumer, the jurisdiction of courts is determined by applicable law, including Regulation (EU) No 1215/2012, which may entitle you to bring and defend proceedings in the member state of your domicile.

The software was developed in accordance with Czech and EU law. If you use the Service in a country for which it is not offered, you do so at your own risk and the Provider is not responsible for compliance of the Service with the law of such country.

We may assign or transfer the agreement, or individual rights and obligations under it, to a legal successor or to an acquirer of the business or assets to which the agreement relates; you will be informed of such a transfer. You may not assign the agreement or your licence without our prior written consent.

Notices and other communications relating to the Service may be delivered to the e-mail address associated with your account; you are responsible for keeping that address current.

These Terms, together with the documents they refer to (in particular the Privacy Policy, the Refund Policy and the Instructions for Use), constitute the entire agreement between you and the Provider concerning the Service and supersede any prior arrangements concerning the Service.

Should any provision of these Terms prove invalid or ineffective, the validity of the remaining provisions is not affected; such a provision will be replaced by one closest to it in meaning and purpose. Failure to exercise any right under these Terms does not constitute a waiver of that right.

These Terms are effective as of 18 August 2026 and replace all previous versions.
