Effective July 13, 2026
These Terms of Service ("Terms") govern your use of Lensmark, operated by DAGNOSTICS LLC ("Lensmark," "we," "us," or "our"). By creating an account or using Lensmark, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.
Lensmark is a history teller. You give it a photo or a question, and it identifies what you are looking at (a landmark, building, monument, work of art, or site) and returns a verified, sourced history: what it is, where it stands, how old it is, who made it and why, and why it matters. Identification is the means; the verified history is the product.
We ground our answers in retrieved sources and state honestly when something is uncertain or cannot be verified. We do not, however, guarantee that every answer is complete or correct. Lensmark is an informational tool. It is not a navigation service, a trip planner, a restaurant or itinerary recommender, or a substitute for professional advice.
When you use Lensmark, you agree not to:
If you find someone misusing the Service, tell us at dag@lensmark.ai.
You keep ownership of the photos, questions, and other content you provide ("Your Content"). You do not have to provide any content, and you choose what to provide.
To operate the Service, you grant us a worldwide, non-exclusive, royalty-free license to host, store, reproduce, process, and use Your Content for the purposes of providing, securing, and maintaining the Service, and, where you have given consent, improving our models and results. This license lasts only as long as we need it for those purposes; when you delete Your Content or your account, we stop using it as described in the Privacy Policy, subject to reasonable time for deletion and to lawful retention.
You represent that you have the rights necessary to provide Your Content, and that it is lawful. If you give us feedback or suggestions, we may use them without obligation to you.
The Service, including its software, design, branding, and the compiled corpus of verified histories and narratives, belongs to us or our licensors and is protected by intellectual property laws. We grant you a limited, personal, non-exclusive, non-transferable license to use the Service under these Terms. You may not copy, modify, distribute, sell, or lease any part of the Service, and you may not use our name, logos, or branding without our permission.
Lensmark uses artificial intelligence and retrieved sources to produce its answers. Even though we ground answers in sources and flag uncertainty, outputs may contain errors, omissions, or outdated information. You are responsible for how you use them, and you should verify anything important before relying on it. Lensmark does not provide legal, financial, medical, safety, or other professional advice, and its outputs are not a substitute for a qualified professional.
The Service relies on and links to third-party services and content (for example, mapping, recognition, and payment providers, and external sources cited in our research). Your use of those services may be subject to their own terms, and we are not responsible for third-party content or for the availability or accuracy of external sources.
You can stop using Lensmark at any time and delete your account. We may suspend or terminate your access, or remove content, if you materially or repeatedly breach these Terms, if we are required to by law, or if your conduct causes harm or liability to a user, a third party, or us. Where reasonable, we will give you notice and a chance to address the issue first, unless doing so would cause harm, violate the law, or compromise the security or integrity of the Service. Sections that by their nature should survive termination (including content licenses you have granted for already-shared content, disclaimers, limitations of liability, and dispute terms) survive.
To the extent permitted by law, the Service is provided "AS IS" and "AS AVAILABLE," without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that any answer will be accurate, complete, or meet your needs.
To the extent permitted by law, Lensmark and its owners, employees, and providers are not liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenues, data, goodwill, or business opportunities. Our total liability arising out of or relating to these Terms or the Service is limited to the greater of (1) one hundred U.S. dollars ($100) or (2) the amounts you paid us to use the Service in the twelve months before the event giving rise to the liability. These limits do not apply to liability that cannot be limited by law, such as for gross negligence or willful misconduct.
If you use the Service on behalf of an organization, and to the extent permitted by law, you will indemnify and hold harmless Lensmark and its owners, employees, and providers from third-party claims, losses, and expenses (including reasonable legal fees) arising out of your unlawful use of the Service or your breach of these Terms.
These Terms are governed by the laws of the State of Florida, USA, without regard to conflict-of-laws rules. Before filing a claim, you agree to try to resolve it with us informally by contacting dag@lensmark.ai. Any dispute that is not resolved informally will be brought exclusively in the state or federal courts located in Broward County, Florida, and you and Lensmark consent to the jurisdiction of those courts.
We may update these Terms to reflect changes to the Service or for legal, regulatory, or security reasons. If we make material changes, we will provide reasonable notice, for example by posting the updated Terms with a new effective date or notifying you in the app. If you continue to use the Service after the changes take effect, you accept the updated Terms. If you do not agree, stop using the Service and, if you wish, delete your account.
