Privacy Policy – Cây Thuốc Nam

Last updated: November 3, 2026

Cây Thuốc Nam is an app developed by Tran Minh Luan, HTI GROUP Joint Stock Company. We respect your privacy. This Privacy Policy explains how the app handles your data. In short: the app works fully offline and does not collect, send, or share any of your personal data.

1. Information We Do Not Collect

Cây Thuốc Nam requires no account and collects no personal information, including: your name, email address, phone number, location, contacts, photos, or any other data that could identify you.

The app contains no advertising, uses no analytics tools, and does not track how you use it.

2. Data Stored On Your Device

All of the app's data stays on your device, including:

The built-in lookup database of medicinal plants, folk remedies, and disease groups.

Your list of favorite plants (only plant IDs are stored, with no personal information).

Whether you have read and accepted the usage notice.

This data never leaves your device. When you uninstall the app, this data is deleted along with it.

3. Fully Offline

The app works fully offline and does not require an internet connection. It sends no data to our servers or to any third party, because there is no server collecting data.

4. Third-Party Services

The app integrates no advertising, analytics, or any other third-party service that collects data. Therefore, no third party receives data from the app.

5. Children's Privacy

Because the app collects no data at all, this policy applies equally to all users, including children.

6. Medical Information Notice

The content in the app (medicinal plant and folk remedy information) is for reference only and is not a substitute for advice, diagnosis, or treatment from a physician or healthcare professional. Please consult a professional before applying any remedy.

7. Security

Because all data stays on your device, protecting it depends on your device's own security (screen lock, operating system updates). We recommend keeping your device secure and up to date.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. Your continued use of the app after a change means you accept the new policy.
