Plain-English summary of who runs this site, what data it collects, and the nature of everything you see here.
Author and contact
This prototype is an individual portfolio piece by Guangyu Zhu. It is not affiliated with any company, hospital, or healthcare provider. Contact: garyjuly688@gmail.com.
Synthetic data only
Every number, identifier, code, and chart on this site is produced by a deterministic, seeded data-generation algorithm. No real patient, hospital, vendor, or commercial information is involved. Diagnosis codes are synthetic identifiers (e.g. DX_RES_01), not real ICD-10 classifications. The model structure and parameters are illustrative and do not reflect any specific organisation's policies.
Hosting and analytics
Hosted on Vercel Inc., which acts as a data processor under the GDPR. The site does not set tracking cookies, does not run third-party analytics, and does not collect personal data from visitors. Platform-level telemetry (server logs, request routing) is governed by Vercel's privacy policy.
No medical advice
Nothing on this site constitutes medical advice, clinical guidance, or healthcare information for patients. The cases and disease groups shown are demonstrative constructs for a cost-allocation methodology and have no clinical validity.
Source-code licence
Source code is released under the MIT licence. Synthetic data files are released under the same terms and may be freely reused.
GDPR rights
EU/EEA visitors retain the rights of access, rectification, erasure, and complaint to a national supervisory authority. Because this site does not collect personal data beyond hosting-level telemetry, no separate request mechanism is needed; please email the address above with any concern.
