Shenzhen Lankexun Intelligent Technology Co., Ltd. (“we,” “us,” or “our”) operates the BFOUR series of mobile applications (the “Apps”), including BFOUR、BFOUR+、BF-Home, and Grill 5.0. This Privacy Policy describes how we collect, use, process, and disclose your information, including personal data, in connection with your use of the BFOUR Apps and their associated BFOUR Smart Thermometer services.
By downloading, accessing, or using any of the Apps, you acknowledge that you have read, understood, and agree to the collection and use of your information as outlined in this Privacy Policy. If you do not agree with this policy, you must not use the Apps.
We collect personal data that you voluntarily provide to us, as well as data generated through your use of the Apps. The types of data collected include:
2.1 Personal Identification Data
• Contact information (e.g., email address, phone number) when you register an account, subscribe to notifications, or contact customer support.
• Account credentials (e.g., username, password) for accessing the Apps’ features.
• Device information (e.g., device model, operating system version, unique device identifiers, IP address).
• App usage data (e.g., features accessed, interaction history, cooking preferences, temperature monitoring records related to BFOUR Smart Thermometer).
• Location data (only if you enable location services, used solely to provide location-based features or optimize BFOUR Smart Thermometer service delivery, with your explicit consent).
• Log data (e.g., access times, error logs, connection status) for troubleshooting and improving App performance.
• Bluetooth/WiFi connection data (e.g., device pairing information) to enable communication with BFOUR Smart Thermometer.
We use your personal data for the following legitimate purposes, in compliance with GDPR Article 6:
• To provide and maintain the Apps’ core functionality (e.g., temperature monitoring, remote control of BFOUR Smart Thermometer, data synchronization).
• To personalize your experience (e.g., saving cooking presets for BFOUR Smart Thermometer, tailoring recommendations based on usage habits).
• To improve and optimize the Apps and BFOUR Smart Thermometer (e.g., analyzing usage patterns, fixing bugs, developing new features).
• To communicate with you (e.g., sending service updates for the Apps or BFOUR Smart Thermometer, response to inquiries, important notices about your account).
• To ensure security and prevent fraud (e.g., verifying account authenticity, detecting unauthorized access to the Apps or connected BFOUR Smart Thermometer).
• To comply with legal obligations (e.g., responding to regulatory requests, enforcing terms of service).
We will not use your data for any purpose unrelated to the above without your prior consent.
4. Data Sharing and Disclosure
We do not sell, rent, or share your personal data with third parties for marketing purposes without your explicit consent. We may share your data in the following limited circumstances:
• Service Providers: With trusted third-party service providers who assist us in operating the Apps or supporting BFOUR Smart Thermometer (e.g., cloud storage providers, analytics tools, payment processors). These providers are contractually obligated to protect your data and only use it to perform the services we request.
• Legal Compliance: If required by law, regulation, or legal process (e.g., court order, subpoena), or to protect our rights, property, or safety, or the rights, property, or safety of others.
We retain your personal data only for as long as necessary to fulfill the purposes for which it was collected, or as required by law. When data is no longer needed, we will securely delete or anonymize it in accordance with GDPR requirements.
• Account data: Retained for the duration of your account existence. You may request account deletion at any time (see Section 8).
• Anonymized data: May be retained indefinitely for analytical or research purposes, as it cannot be linked to any individual.
We seek to implement reasonable organizational, technical, and administrative measures to protect personal data within our organization. These measures are designed to mitigate risks of unauthorized access, disclosure, alteration, or destruction of your personal data, including:
• Encryption of data in transit (e.g., via SSL/TLS) and at rest.
• Access controls to limit data access to authorized personnel only.
• Regular security audits and updates to App infrastructure, BFOUR Smart Thermometer related data processing systems, and data storage environments.
• Secure storage of data on compliant servers with industry-standard protection protocols.
Unfortunately, no data transmission or storage system can be guaranteed to be 100% secure. We cannot ensure or warrant the absolute security of your personal data. If you have reason to believe that your account or interaction with us is no longer secure (e.g., if you suspect unauthorized access to your account), please contact us immediately in accordance with the “Contact Us” section below.
