Welcome to our product. ElfKey (hereinafter referred to as "the Software") is a custom product configuration tool developed and operated by Shenzhen RDING TECH CO., LIMITED (hereinafter referred to as "we" or "us"). We fully understand the importance of personal information to you and will do our utmost to protect your personal information security. This Privacy Policy explains how we collect, use, store and protect your information within this Software.
Please read the entire content of this Privacy Policy carefully and fully understand it before using the Software. Once you start using it, you are deemed to have agreed to all terms of this Privacy Policy. If you do not agree with any part of this policy, please stop using the Software immediately. If you have any questions, please contact us through the contact details provided in this policy.
This Privacy Policy mainly covers the following contents:
I. Definitions;
II. How We Collect and Use Your Personal Information;
III. How We Store and Protect Your Personal Information;
IV. How We Share, Transfer, and Publicly Disclose Your Personal Information;
V. How This Policy Will Be Updated;
VI. How to Contact Us;
Bluetooth & USB Permission: To establish a connection with the hardware product you purchased and realize functions such as key-value reading/writing, we need to request Bluetooth or USB communication permission. This permission is only used when you actively connect the product and will not scan in the background continuously. If you deny this authorization, you will not be able to connect the product device and perform configurations.
Location Permission (Android 6–11 only): Due to Android system requirements, Bluetooth scanning (BLE) requires the location permission on Android versions below 12. ElfKey does not collect or upload any location data. This permission is used solely by the system to allow Bluetooth device discovery and is not accessed by our code for any location purpose.
Network Access Permission: To achieve software updates and downloads, we may need a network connection. This permission is only used when you actively click "Check for Updates" and will not secretly use the network in the background. If you deny network access, you will not be able to use the online update and software download services, but it will not affect local product configuration and read/write functions.
Fingerprint / Face ID Authentication: When you enable the text note lock feature and choose fingerprint/Face ID as the verification method, the Software invokes the biometric authentication capability provided by your device's operating system, solely to verify your identity on your device for unlocking your locked notes. The enrollment, matching and storage of fingerprint/Face ID data are completed entirely by the operating system within the secure hardware of your device (e.g., the Secure Enclave on iOS or the Trusted Execution Environment on Android). The Software cannot access, does not collect, does not store, and never uploads your fingerprint/Face ID templates or any raw biometric data; it only receives a "verified / not verified" result returned by the system. You may turn off this verification method in the Software at any time and switch to an in-app password.
Other Notes: This Software is a pure tool application, requires no account registration and does not collect any personally identifiable information (such as name, mobile phone number, location, etc.). The Bluetooth device identifier (deviceId) of your paired hardware is stored locally on your device only for auto-reconnection purposes and is never uploaded to any server. The above permissions are designed solely around the core functions of hardware configuration. We will not use them for other purposes or share them with third parties. You can completely delete all local data by uninstalling the Software.
We: refers to Shenzhen RDING TECH CO., LIMITED, the developer and operator of this Software.
Personal Information: refers to various information recorded electronically or otherwise that relates to an identified or identifiable natural person, excluding information that has been anonymized.
Sensitive Personal Information: refers to personal information that, if leaked or illegally used, could lead to discrimination or serious harm to a person's person or property. This Software does not collect any sensitive personal information.
Minor: refers to a natural person under the age of 18.
Child: refers to a natural person under the age of 14.
This Software is a hardware configuration tool and is not directed at children under the age of 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. Since this Software does not collect any personal information from any user, no children's data is collected or processed.
If you are a parent or guardian and believe that your child has provided us with personal information through any of our services, please contact us using the details provided in Section VI. We will investigate and delete such information promptly in compliance with applicable laws (such as COPPA, GDPR-K, etc.).
This Software is a pure tool application designed to help users connect to supporting hardware products via Bluetooth or USB, and perform operations such as key-value settings.
We do not actively collect any of your personal information. You do not need to register an account to use all functions. This Software will not ask you to provide personal identity information such as name, mobile phone number, email address, ID number, nor will it access your location, contacts, photo albums, SMS, etc.
When connecting to hardware devices, this Software may need to access the following system permissions, but these permissions are only used for hardware configuration functions and do not involve extraction of personal information:
· Bluetooth/USB Permission: Used to discover and connect to the supporting product hardware you purchased, and to realize the reading and writing of data.
· Location Permission (Android 6–11): Required by the Android operating system for BLE scanning. The app does not access, collect, or transmit any geographic location data. This is a system-level requirement unrelated to our data practices.
· Network Permission (if online upgrade function is available): Only used to download Software updates from our official server, and will not upload any of your personal data.
· Fingerprint/Face ID Authentication (text note lock, optional): Only invokes the local biometric authentication capability provided by the operating system to unlock your locked text notes. The Software does not collect, store or upload any of your biometric data and only receives the authentication result returned by the system.
Please note that this Software does not include account registration function, therefore it does not involve creation, login or verification of user accounts. If personal information needs to be collected due to future feature expansion, we will update this policy in advance and seek your explicit consent.
Since this Software does not collect personal information, there is no issue concerning the retention period or protection measures for personal information.
For the configuration files, paired Bluetooth device identifiers (deviceId), and logs you save locally, they are stored only on your device. The deviceId is used exclusively for auto-reconnection to your hardware and is never transmitted externally. You can clear them by uninstalling this Software or manually deleting the relevant files. We strongly recommend that you keep your device safe and regularly back up important configuration files to prevent loss.
Although we do not process personal information, we still adopt commercially reasonable technical and administrative measures to protect the communication security of the Software, preventing unauthorized access or data leaks. If a security incident occurs, we will notify you promptly and report to the regulatory authorities in accordance with legal requirements.
Since we do not collect your personal information, there is no circumstance of sharing, transferring, or publicly disclosing your personal information to any third party.
Under special circumstances stipulated by the following laws and regulations, we may need to share or disclose necessary information (however, this Software currently does not collect personal information, so such situations rarely occur):
1. Directly related to national security or national defense security;
2. Directly related to criminal investigation, prosecution, trial, and execution of judgments;
3. To protect the major legitimate rights and interests of you or other individuals, such as life and property, but it is difficult to obtain your consent;

6. Necessary for concluding or performing a contract at the request of the personal information subject;

8. Other circumstances stipulated by laws and regulations.
We may update this Privacy Policy from time to time based on changes in laws and regulations, product feature adjustments, etc.
Without your explicit consent, we will not reduce your rights granted under this policy. Any revised policy will be published on this page, and you can view the latest version at any time through the "About" or "Privacy Policy" entry in the Software.
For material changes, we will also remind you through prominent methods such as in-app pop-ups or notifications, and re-obtain your consent. If you continue to use the Software after the policy update, it is deemed that you accept the revised Privacy Policy.
