DERMA READER ("the app") is developed by H-Cloud Co., Ltd. ("we"). This
policy describes what data the app handles and how.

1. Data stored on your device

All data created in the app, including client records, captured skin and
scalp images, analysis results, and reports, is stored locally on your
device only. We do not collect, receive, or have access to this data. The
app has no user accounts, and no analytics, advertising, or tracking
services are included.

2. Report sharing (QR download)

When you choose to share a report using the QR download feature, the report
file (PDF) is uploaded over an encrypted connection (HTTPS) to a relay
server operated by us, solely to generate a temporary download link. The
file is held in the server's memory only, is never written to disk or any
database, and is automatically deleted when the link expires (5 minutes).
The server stores no personal information and has no user accounts. This
transfer happens only when you tap the QR share button.

3. Permissions

• Camera: used to capture skin and scalp photos. Photos are processed and
  stored on your device only.
• Location and Local Network: used only to verify and maintain the Wi-Fi
  connection to the dedicated camera device. No location data is collected
  or transmitted.
• Microphone: included as part of the camera component; no audio is
  recorded.

4. Data retention and deletion

Because your data is stored only on your device, you control it. You can
delete records in the app at any time, and uninstalling the app removes all
app data from the device.

5. Third parties

We do not share personal data with any third party. The app does not use
third-party AI services; all analysis runs on your device. The app may
contact the app store's version lookup service to check for app updates;
this request contains no personal data.

6. Children

The app is intended for professional use and is not directed at children.

7. Changes

If our data practices change, we will update this policy and the effective
date above.
