Privacy Policy

Last updated: July 10, 2026

Medex is operated by Henge. This policy explains what information we collect, why we collect it, and how you can control it.

Information we collect

Medex may collect profile details you provide, health information you enter or speak, attached photos or videos, voice-call audio and transcripts, account identifiers from sign-in, push tokens, and technical information needed to run and secure the service.

How we use information

We use information to provide health tracking, contextual responses, summaries, reminders, account access, support, safety checks, and service improvement. To generate responses, we share the information you provide with third-party AI services as described below. We do not sell personal data and do not use it for third-party advertising.

Third-party AI service (Anthropic)

Medex uses Anthropic's Claude AI to organize your intake, understand your messages, describe attached photos and videos, and generate the responses you see in the app. To do this, we send Anthropic the content you provide — including the text you write, your health profile and history, attached photos or videos, and voice transcripts — together with the context needed to answer you.

Anthropic (Anthropic PBC, United States) processes this data only to provide the AI features to us and does not use your inputs or outputs to train its models. Anthropic is contractually bound to protect your data with safeguards equivalent to those described in this policy. We ask for your permission inside the app before any of your data is sent to this service. Learn more at anthropic.com/legal/privacy.

Third-party AI service (OpenAI)

Medex uses OpenAI for live voice conversations and speech-to-text. When you start a voice conversation or choose to transcribe an audio recording, we send OpenAI the audio you provide and the resulting transcript. OpenAI processes this data to provide the requested live voice or transcription feature.

OpenAI, L.L.C. (United States) does not use our API inputs or outputs to train its models. We require OpenAI to protect this data with safeguards equivalent to those described in this policy. We ask for your permission inside the app before any of your health information is sent to Anthropic or OpenAI. Learn more at openai.com/policies/privacy-policy.

Health data

Health information is sensitive. Medex uses it only to provide the app features you choose to use, including the AI processing described above. AI-generated responses may be inaccurate or incomplete and are not medical advice.

Other service providers

We use Supabase, Inc. for authentication, database, and encrypted cloud storage. Supabase processes account identifiers, health information, and files that you choose to save in Medex only as needed to operate the service. We may also use Apple and Expo notification services to deliver reminders you choose to enable.

Retention and deletion

We keep information while your account is active or as needed to provide the service. You can delete your account from Settings in the Medex app. You can also contact support@medex.my for privacy requests.

Children

Medex is not intended for children under 16. We do not knowingly collect personal information from children under 16.
