Privacy Policy

Last updated: August 2026

1. Introduction

NexisMate (the "App") is operated by FusionNexis. This Privacy Policy explains how we collect, use, store, and protect your personal information. The App is intended for individual users aged 18 or older to manage their own health records. By using the App, you acknowledge that you have read and accepted this policy.

2. Data We Collect

Account data: email, password hash, authentication tokens.

Patient profile: name, sex, age, medical record number, diagnosis (either supplied by you or extracted by AI from your uploads).

Health data: medical report images you upload, along with the structured indicators, reference ranges, and sampling dates that AI extracts from them.

Operational data: crash logs and performance metrics (excluding health data) used to diagnose app issues.

We do not collect advertising identifiers, do not track behavior, and do not integrate third-party advertising SDKs.

3. How We Use Your Data

Your data is used solely to: display your own health record within the App; call AI services to recognize reports; render indicator trend charts; authenticate you and log security events; improve app reliability. We do not use your health data for advertising, marketing, profiling, or resale.

4. Third-party Services

For report recognition, report images are transmitted transiently to the following large-language-model providers: Anthropic (Claude family) and Alibaba Cloud Qwen-VL. These providers process the images only for the recognition request and do not use your data to train their models.

Authentication supports Google OAuth; when you sign in with Google, you authorize Google to share your email and basic profile with the App.

Object storage: Alibaba Cloud OSS, Singapore region, used to persist original report images.

5. Storage, Encryption & Retention

Your data is stored in Alibaba Cloud Singapore region. Data in transit uses TLS 1.2 or higher; sensitive fields at rest (name, diagnosis, etc.) are encrypted with AES-256-GCM.

Retention: as long as your account exists, we retain your health record data. When you trigger "Delete Account" inside the App, we immediately hard-delete all related database records. Original report image files on object storage are retained for audit traceability and are not deleted automatically; email support@fusionnexis.com to request their removal.

6. Cross-border Data Transfer

Your data is stored in Singapore by default; during report recognition, images are transmitted to the LLM providers' servers in their respective operating regions. Data does not flow into mainland China as part of this process. Please do not use the App to upload information subject to mainland China's cross-border data restrictions.

7. Your Rights

You have the right to:

• view all data we hold about you (the entire dataset is visible within the App UI);
• obtain a copy of your data (via email request);
• delete your account and data at any time ("Profile → Delete Account", or via these instructions);
• withdraw consent and stop using the App at any time;
• raise complaints about any practice in this policy.

8. Minors

The App is not directed at children under 18. If we discover that we have inadvertently collected personal information from a minor, we will delete it. If you are the legal guardian of a minor and believe they have provided us with information, please contact us so we can assist with deletion.

9. Changes to This Policy

We may update this Privacy Policy from time to time — for example, when new features are added or laws change. Material changes will be prominently notified on app launch, and the "Last updated" date at the top of this page will reflect the change. Continued use after the effective date constitutes acceptance.
