1. Introduction

Thảo Nguyên Xanh is developed and operated by Nguyễn Quốc Huy. This app is published as a personal app. I respect user privacy and am committed to protecting personal data when users access and use the application.

This policy explains how the app handles GPS location, camera access, photos, login account information and related app information.

For app reviewers: The app requires users to sign in with an existing account. The app does not provide account registration or account creation inside the app. The app also does not automatically activate the camera, does not take photos without user action and does not access GPS location outside user-triggered app features.

2. Login-Only Account Model

The app requires users to sign in with an existing account. Users cannot create a new account directly inside the app. Accounts are created, issued or managed outside the app by the developer, administrator, service owner or another authorized process.

Login information is used only to authenticate users, protect access to app features, apply user permissions where applicable and associate app records with the correct user account.

Because the app does not allow users to create accounts inside the app, it does not provide an in-app account registration flow. Users who need help with access, account removal, account disabling or data-related requests may contact the developer using the contact information provided in this policy.

3. Data the App May Collect

3.1 Location Data

The app may request access to the device's location when a user uses features that require location verification. Location data may include:

Latitude and longitude of the device.
Date and time when the location is recorded.
Approximate address or area derived from coordinates, if this feature is used.
App record, request, task or workflow information related to the recorded location.

3.2 Camera and Photos

The app may request camera access so users can take photos for app features. Photo data may include:

Photos taken directly by the user inside the app.
Photos selected by the user from the device photo library, if this feature is available.
Date and time when a photo is uploaded or attached.
App record, request, task or workflow information to which the photo is attached.

3.3 Login and Profile Information

Because the app requires sign-in, the app may process login and profile information such as username, email address, display name, user ID, role, permissions, authentication status, activity records and related app records.

3.4 Technical and Usage Information

The app may process limited technical information needed to operate, secure and improve the service, such as device type, app version, error logs, server logs, request timestamps and basic usage events.

4. How the App Uses Data

Data is used for the following purposes:

To authenticate users and protect access to the app.
To provide app features that require location verification.
To allow users to take and attach photos inside the app.
To support review, verification, history tracking and app workflows.
To protect app security, troubleshoot issues, prevent fraud and prevent misuse.
To improve app quality, reliability and user experience.

No advertising use: I do not sell GPS, camera, photo, login or profile data. I do not use this data for personalized advertising or tracking users outside the functionality of the app.

5. Device Permissions

5.1 Location Permission

Location permission is used to record coordinates when users perform features that require location verification. Users may deny or revoke this permission in their device settings.

5.2 Camera Permission

Camera permission is used to allow users to take photos and attach or upload them to relevant app records. The app uses the camera only after the user intentionally performs a camera-related action.

5.3 Photo Library Permission

If the app supports selecting photos from the device, photo library permission is used only when users choose to attach photos from their device to an app record, request or workflow.

Suggested Permission Prompt Text

The following text may be used in in-app permission rationale messages.

Location Access This app needs access to your location to record coordinates when you use features that require location verification. Location data is used only to provide app features and is not used for advertising. [Not Now] [Allow]

Camera Access This app needs access to your camera so you can take photos and attach them to app records. The app does not take photos automatically without your action. [Not Now] [Allow]

6. Data Sharing

Data may be processed by the app's backend systems, hosting providers, cloud storage providers, analytics, crash reporting or security service providers where these services are used to operate, maintain and protect the app.

I do not sell users' personal data to third parties. Data is shared only when necessary to operate the app, provide app features, comply with legal obligations, protect security, prevent fraud or respond to valid legal requests.

If third-party services such as analytics, crash reporting, cloud storage, maps or push notifications are used, replace this note with the exact third-party service names before publishing, if applicable.

7. Security

Data is transmitted between the app and servers using secure HTTPS connections where server communication is required. Appropriate technical and organizational measures are used to protect user data, including:

Account-based access control.
Role-based permissions where applicable.
Server-side and storage security controls.
Reasonable access restrictions for unauthorized persons.
Error monitoring and security checks where applicable.

8. Data Retention

GPS location data, photos, login account data and app records are retained only for as long as necessary to provide app features, maintain user records, support security, comply with legal obligations, resolve disputes or fulfill legitimate operational needs.

When data is no longer required, it may be deleted, anonymized or archived according to the app's data retention practices.

9. User Choices and Data Requests

Users may:

Deny camera or location permission.
Revoke camera or location permission through device settings.
Request access, correction or deletion of personal data where applicable.
Request that their login account be disabled or removed where applicable.
Contact the developer to ask how their data is collected, used and stored.

If camera or location permission is denied or revoked, some features that require GPS or photo capture may not function properly.

Since users cannot create accounts directly inside the app, account creation and account management are handled outside the app. Users who want to request account removal, account disabling or deletion of related personal data may contact the developer using the contact details below.

Some data may be retained where necessary for legal compliance, security, fraud prevention, dispute resolution, backup integrity or other legitimate obligations.

10. Children

The app is not intended for children and does not knowingly collect personal data from children. If you believe a child has provided personal data, please contact the developer so the data can be reviewed and deleted where appropriate.

11. Changes to This Privacy Policy

This Privacy Policy may be updated when app features change or when legal, operational or security requirements change. The latest version will be published on this page.
