These are important questions for any connected device provider. Below, we share our responses to common data security questions from global customers and partners, covering Wonlex smartwatch applications and the SETracker platform — from data storage and encryption to access controls and ongoing security practices.

Q1: Please describe the key security controls currently implemented, including, where applicable, data-in-transit encryption, user authentication and authorization, API security measures, and access controls for stored or processed data.
Data Transmission Security:
All communications between the App, devices, and servers are protected using HTTPS (TLS) encryption. Mutual certificate authentication (mTLS) and AES-256 encryption are applied to ensure secure data transmission.
User Authentication and Authorization:User access is authenticated through account and password verification, with support for Google Sign-In SDK integration. All App features require users to complete authentication before access is granted.
API Security:
All API endpoints are protected via HTTPS and TLS with mutual TLS (mTLS). Unauthorized requests are blocked from accessing any API resources.
Access Control for Stored and Processed Data:
The server-side system implements Role-Based Access Control (RBAC). Only authorized personnel with valid credentials can access stored data. User data is logically isolated by account, preventing unauthorized access between different users.
Q2: Where are the servers hosting the application and related services located, and where is the data processed? Please specify the country/region and the infrastructure or cloud service provider, if applicable.
All application hosting and data processing runs on Amazon Web Services (AWS) infrastructure located in Frankfurt, Germany. No data processing takes place outside this region.
Q3: Is any personal or device-related data processed, stored, or transferred outside the EU/EEA? If yes, please specify the relevant countries/regions and briefly describe the transfer mechanism or safeguards applied.
The majority of personal and device-related data is processed and stored on AWS servers located in Frankfurt, Germany, within the EU/EEA. Data stored on European servers includes:
Q4: Please describe how access to sensitive device functions is secured, particularly GPS/location services, microphone access, and camera access. Please include details on authentication, authorization, permission management, and access restrictions.
GPS / Location Data:
Authentication and Authorization:
All sensitive functions require users to be authenticated through App login. Operating system-level permission prompts ensure that user consent is obtained before accessing any sensitive hardware features.Frequency:
Vulnerability assessments are conducted approximately every three months. Security patches are deployed on an as-needed basis according to identified vulnerabilities and security findings.Q6: Please describe your process for identifying, assessing, prioritizing, remediating, and deploying updates for security vulnerabilities. Please also explain how critical vulnerabilities are handled and how customers are notified when relevant security updates are available.
Vulnerability Management Process:
After validation and testing, security fixes are deployed through OTA (Over-the-Air) app updates and server-side patch releases.
Handling of Critical Vulnerabilities:
Critical vulnerabilities are handled with the highest priority. Emergency patches are developed, tested, and deployed as quickly as possible to address security risks.When security updates become available, customers are informed through in-app notifications and release notes.
