Hello!
Thank you for your feedback!
The founders of Air-Clinic are medical doctors and they understand totally the implications of patient privacy and client security.
Calls and chats between doctor and client are end-to-end which means that a third party has no access to it. Case history notes are well-secured and encrypted. It can only be accessed by the attending doctor and the patient.

We don't publish clients medical data on the blockchain. The blockchain is a system that increases the efficiency of currency exchanges and content rewarding.

We hope it's clear now!
