# Get in Touch Nodule Navigator is an educational project about pulmonary nodule imaging. The form on [/contact](https://nodule.app/contact) is the only channel it maintains, and every message sent through it is read. ## What to send **Corrections to educational content.** If a definition, a figure, a guideline summary, or a citation on this site is wrong, out of date, or misleading, say so. Point at the specific page and the specific claim, and include the source you believe is correct if you have one. Content here is grounded in Lung-RADS 2022, the Fleischner Society 2017 guidelines, USPSTF screening recommendations, and peer-reviewed literature, and corrections against those sources are the most useful messages this project receives. **Accessibility problems.** If something is unusable with a screen reader, unreadable at your text size, impossible to operate by keyboard, or fails on your device or browser, that is a defect worth reporting. Describe what you were trying to do, what happened instead, and which browser, operating system, and assistive technology you were using. **General feedback and questions about the project.** Suggestions for topics to cover, notes on which explanations landed and which did not, questions about how a feature works, and questions about how the site handles data are all welcome. ## Please do not send health information **Do not use this form to send personal health information, patient details, imaging studies, radiology reports, or a clinical question about a specific case — your own or anyone else's.** Messages of that kind cannot be answered and should not be sent. Nodule Navigator is an educational resource, not a clinical service. It is not a medical device, it provides no diagnosis, and no one behind this project can review a scan, interpret a finding, or advise on treatment. There is no doctor-patient relationship and none is created by writing in. **If you have a question or a worry about a lung nodule, take it to a qualified physician or pulmonologist — someone who can see your imaging and your history.** If your symptoms are severe or worsening, contact emergency services or your local urgent care. ## Response time This is a small, independently maintained educational project rather than a staffed support desk. Expect a reply within a few business days, and allow up to two weeks during busy stretches. Reports of factual errors and accessibility defects are prioritised over everything else. Not every message gets an individual reply, but every one is read, and corrections are acted on whether or not a response goes back out. If a correction leads to a change, the affected page is updated and its entry in the sitemap is re-dated. Submissions are delivered by Formspree, the single third-party service this site uses. Your name, email address, and message are passed to Formspree solely to deliver the message. Nothing else on the site sends data anywhere. The [privacy notice](https://nodule.app/privacy) sets out exactly what is and is not collected, and the [terms of use](https://nodule.app/terms) describe the educational scope of this site. --- *Educational use only · Not a medical device.* This document mirrors the page at .
