Privacy Policy

Effective date: 2026-02-20

1. Scope

This policy applies to the LightNeedle iOS app and its official support pages. LightNeedle is a GLP-1 treatment execution management tool for reminders, logging, and trend review. It does not provide diagnosis or prescription services.

2. Data Categories We Process

Depending on your in-app usage, the app may process:

Treatment plan data: protocol type, reminder times, execution rhythm, and phase progress;
Treatment record data: injection/intake logs, weight logs, side-effect logs, and notes;
User-submitted content: optional photo attachments and text notes;
Apple Health weight data: read/write only after explicit authorization.

3. Purpose of Use

Generate reminders and maintain execution rhythm;
Display treatment history in timeline and trend pages;
Execute export, sync, and data management when triggered by the user;
Support issue investigation and product quality improvement under data minimization principles.

4. Storage, Permissions, and Security

The current version is local-first. Core treatment records are stored on your device by default. We do not sell health data to third parties. Permissions such as notifications, photo/camera, and Health are controlled at the system level and can be revoked by the user at any time.

5. Third-party Services and Data Sharing

We only call Apple platform capabilities when required (for example, notifications and HealthKit). Unless required by law or explicitly authorized by you, we do not share identifiable health records with unrelated third parties.

6. Your Rights

You can edit or delete individual records inside the app;
You can export CSV files for self-management and migration;
You can clear local records through the in-app reset option;
You can disable specific processing by revoking system permissions.

7. Minor Users

If you are under the legal age in your jurisdiction, please use the product under guardian guidance.

8. Updates and Contact

We may update this policy when product capabilities or legal requirements change. The latest version is published on the website. For privacy-related questions, contact 1547654938@qq.com or visit the Support Center.
