Privacy Policy
Sầu Riêng AI app · Effective 5 November 2026
Sầu Riêng AI helps durian growers keep records of their orchards, seasons, costs and harvests, and detect diseases on durian leaves, trunks and fruit. This page explains what data the app collects, how it collects it, what it is used for, who it is shared with, and how you can delete it.
1. Data we collect and how we collect it
| Data | How it is collected |
|---|---|
| Account information: account identifier and display name. We do not read or store your email, and we never receive your password. | Sent to us by Google or Apple when you choose to sign in with that account. |
| Orchard data: orchards, plots, seasons, care logs, costs, sales and debts, disease cases, self-checks. | You enter it in the app; it is synced to our server. |
| Photos of leaves, trunks and fruit. | You take them with the camera or pick them from your photo library. Disease detection runs on your phone. Photos attached to a scan or a disease case are synced to our server, stored privately and only opened through links that expire. |
| Conversations with the AI assistant (see the section below). | You type questions in the app, only after you have agreed. The conversation is kept on your phone; our server only relays it to produce an answer and does not store it. |
| Wrong-answer reports: the question, the answer and the reason you chose. | When you report an answer. |
| Push notification token. | Issued by your phone when you allow the app to send notifications. |
| Technical data: time, IP address, error codes. | Logged by our server when the app connects to it. |
The AI assistant and Google Gemini
The AI assistant uses Google Gemini (Google's AI service) to write answers. The app sends data only after you tap “Đồng ý” (I agree) in the assistant's notice. You can turn it off at any time in Settings; once off, nothing more is sent and you can still search the articles downloaded to your phone.
Each time you ask, the following is sent through our server to Google Gemini:
- Your question.
- Up to the 6 most recent messages of the conversation, so the assistant understands the context.
- If you have selected a season or a disease case: the season name, stage, start date, expected harvest date, end date, total recorded cost, confirmed sales, estimated profit; the disease code, status and notes of the case.
- Passages from the app's article library that relate to the question.
Never sent: photos, email, your name, sign-in tokens, account identifier.
We use the paid tier of the Gemini API. Under the Gemini API terms, Google does not use this data to train its models; Google may keep it for a limited time to detect abuse, as those terms describe.
2. How we use data
- Providing the app and syncing: account information, orchard data and photos let you sign in, keep records and see them on another device.
- Answering questions: conversation content lets Google Gemini write an answer, with citations from the article library.
- Improving content: wrong-answer reports are used to fix articles and answers.
- Sending notifications: the push token is used for reminders and notifications you turned on.
- Operations and security: technical data is used to find errors, prevent abuse and limit how often questions can be sent.
- Legal compliance: when a competent authority requires it under the law.
We do not show ads, do not track you across other apps or websites, do not sell your data, and do not use it for any purpose other than those above.
3. Sharing with third parties
| Recipient | Data | Purpose |
|---|---|---|
| Google – Sign in with Google (policy) | Identifier, display name | Sign-in |
| Apple – Sign in with Apple (policy) | Identifier, display name | Sign-in |
| Google – Gemini API (terms, policy) | Conversation content as described above, only after you agree | Writing answers for the AI assistant |
| Expo, Apple Push Notification service, Google Firebase Cloud Messaging (Expo policy) | Push token, notification content | Delivering notifications to your phone |
We share data only with the third parties listed above. Each of them is bound to protect the data at a level equal to or higher than this policy, under their terms of service and privacy policies, and may use it only for the stated purpose. Otherwise we disclose data only when the law requires it.
4. Storage and security
Data is stored on servers we manage and travels over encrypted HTTPS connections. Photos are never public. Data is kept until you delete your account; backups are cleared within 7 days after that.
5. Deleting your account and data
In the app, go to Khác (More) → Tài khoản (Account) → Xóa tài khoản (Delete account). This signs out every device and permanently deletes your account and all your orchard data, disease cases, scans, answer reports, push tokens and photos. It cannot be undone.
If you can no longer access the app, send a request through the support page.
6. Children
The app is meant for adult growers and is not directed at children under 13.
7. Changes to this policy
When this policy changes, we update the effective date at the top and notify you in the app if the change is significant. If the data sent to a third party changes, the app will ask for your consent again before sending it.
