Effective date: September 23, 2026 | Applies to sailymind.com and the SailyMind AI Chat application
This Privacy Policy explains how Shenzhen Sifan AI Technology Co., Ltd. ("SailyMind", "we", "us") collects, uses, stores, and protects information when you use our website and our AI customer-service application (including the SailyMind AI Chat app available on the Shopify App Store and other e-commerce platforms).
1. Who This Policy Covers
Visitors and shoppers ("end users") who interact with the SailyMind chat widget embedded in an online store.
Merchants who install the SailyMind app or use our dashboard at elf-e.e-baixing.com.
2. Information We Collect
a) Data provided by merchants
Account information: name, email address, company name, and contact details you provide when registering or contacting us.
Store configuration: your store domain (e.g. yourstore.myshopify.com), the access token you generate in the SailyMind dashboard, and widget display settings.
Conversation corpora: chat history between your customers and human agents, which our AI engine uses for self-learning so it can reply in your store's tone and with your product knowledge.
b) Data collected from end users (store visitors)
Chat messages they send through the SailyMind widget, including any order numbers, screenshots, or invoice files they voluntarily share in the conversation.
Locale and language information (browser language, region) used to detect the visitor's language and deliver real-time translation.
Basic technical data such as IP address and device/browser type, used for security, spam and fraud filtering, and service delivery.
c) Usage data
Operational metrics such as AI reply counts, response rates, and message timestamps, used for billing metering, analytics dashboards, and service monitoring.
3. How We Use Information
To provide the AI customer-service functionality: generating replies to visitor questions, translating conversations, and routing complex questions to human agents.
To train and continuously improve the self-learning AI model for the merchant's store (learning is store-scoped; one merchant's data is not used to answer another merchant's customers).
To operate our services: account management, token authentication, billing metering, and usage-limit (circuit-breaker) features.
To send service notifications, such as WeCom push alerts for new visitor inquiries.
To detect and filter spam, fraudulent, or malicious messages.
To comply with legal obligations and enforce our Terms of Service.
We do not sell your personal information, and we do not use it for third-party advertising.
4. Legal Bases (GDPR)
Where the EU/UK General Data Protection Regulation applies, we process personal data on the following bases:
Purpose
Legal basis
Delivering the chat service and generating AI replies
Performance of a contract
AI self-learning from conversation history
Legitimate interests (improving service quality for the merchant)
Spam/fraud filtering and security
Legitimate interests
Legal compliance
Legal obligation
Optional marketing communications
Consent (withdrawable at any time)
5. AI Processing and Transparency
AI-generated replies are produced by our self-learning engine (RDSL). When the AI is not confident it can answer correctly, it does not fabricate a response and instead escalates the conversation to a human agent.
The knowledge sources behind AI answers are traceable and auditable for merchants, and AI learning progress can be inspected in the dashboard.
6. Data Sharing
We share personal information only as necessary to operate the service:
With merchants: chat conversations occurring in their stores are visible to the merchant and their human agents.
Service providers: cloud hosting and infrastructure providers who process data on our behalf under data-processing agreements.
Authorities: where required by law, regulation, or valid legal process.
SailyMind is an independent service. Fees for the SailyMind service are collected by SailyMind, not by the e-commerce platform. We are not a "service provider" of your store's platform unless expressly stated; merchants act as the data controller for their end users' chat data and SailyMind acts as a processor with respect to that data.
7. Data Retention
Chat conversation data is retained as long as the merchant's account is active, to support continuity of service and AI learning, or until the merchant requests deletion.
Billing and transaction records are retained as required by applicable tax and accounting law.
When a merchant closes their account, we delete or anonymize associated store data within 30 days, except where retention is legally required.
8. International Transfers
Your information may be transferred to and processed on servers located outside your country or region (including China and cloud regions in Asia). Where required, such transfers rely on standard contractual clauses or equivalent safeguards.
9. Security
We use industry-standard measures to protect your data, including encrypted transport (HTTPS/TLS), token-based access authentication, access controls, and regular security reviews. No method of transmission is 100% secure, but we work to protect your information against unauthorized access, alteration, and destruction.
10. Your Rights
Depending on your jurisdiction (e.g. GDPR, CCPA/CPRA), you may have rights to access, correct, delete, export, or restrict processing of your personal information, and to object to certain processing or withdraw consent.
End users (store visitors): you may exercise your rights by contacting the store you were chatting with, or by contacting us directly at the email below.
Merchants: you may export or request deletion of your account and store data from the SailyMind dashboard or by contacting us.
We do not "sell" or "share" personal information as those terms are defined under the CCPA/CPRA.
11. Children's Privacy
Our service is intended for business use and is not directed to children under 16. If you believe a child has provided personal information through the chat widget, please contact us and we will delete it.
12. Cookies
Our website uses only strictly necessary cookies and similar technologies to deliver and secure the service. We do not use advertising or cross-site tracking cookies.
13. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be announced on this page with a revised effective date. Continued use of the service after changes take effect constitutes acceptance of the updated policy.
