The licence number, the documents and the register fields come from the Republic of Türkiye Ministry of Health's health tourism register, last read on 2026-09-19. Social accounts, photographs, equipment and the treatment list are entered by the clinic itself on that same official portal.
Each document is also published as a W3C Verifiable Credential, signed by us so a machine can confirm the file has not changed since we fetched it. The signature is ours, not the Ministry's.

Two different things are shown here. Document dates come from the documents themselves. Dates marked as read or checked are this site's own observations, and this site only began reading the register in September 2026 — it cannot describe what happened before.
