1. Data Collection
We follow the principle of "Data Minimization." We only collect information strictly necessary for the core functionality of the App:
Account Information: Your email address, used for unique identification and synchronization of access permissions.
Technical Data: Mobile device model, operating system version, and unique device identifier. This is used solely to optimize NFC power transmission and communication parameters for your specific hardware.
Operation Logs: Time of unlock, Device ID, and User ID. These logs allow you to monitor the security of your locks.
2. Data We DO NOT Collect
To protect your privacy, we explicitly state that we DO NOT collect:
Precise or approximate Geolocation data.
Contact lists or social media profiles.
The serial number of your phone's internal NFC chip.
We do not write any private data into your phone's Secure Element (SE).
3. Permissions Notice (NFC and Location)
On certain versions of the Android operating system, enabling NFC communication may trigger a system-level request for Location Permissions. We hereby declare that this is a technical requirement of the OS for low-level hardware communication only. We do not access, store, or upload your location data.
4. Data Storage and Retention
Cloud Storage: For the Online Version, your data is stored securely on Alibaba Cloud servers. We implement industry-standard encryption to protect your data during transmission and at rest.
Retention Period: Logs are retained permanently to provide you with a full history of device access. Data is deleted only when:
You manually delete a specific device or clear the logs.
You choose to delete your account.
Standalone Version: For the Standalone (Offline) version of the App, all data is stored locally on your mobile device. We have no access to, nor do we store any copies of, your local data.
