Privacy Policy
This privacy policy applies to the OPCUA Client Pro app (hereby referred to as "Application") for macOS devices that was created by LUNLI (hereby referred to as "Service Provider") as a Commercial service. This service is intended for use "AS IS".
What information does the Application obtain and how is it used?
The Application does not collect, store, or transmit any personal information to the Service Provider. All OPC UA client and optional local server processing runs entirely on your Mac. Registration is not required to use the Application. The Application may store only your local preferences (such as recently used endpoint URLs, timeouts, or UI state) on your device for convenience, and this data never leaves your device except as part of OPC UA communication you initiate.
Does the Application collect precise real time location information of the device?
This Application does not collect any information about the location of your device.
Network Usage
The Application connects to OPC UA endpoints that you choose (for example via opc.tcp://) to browse address spaces, read and write values, create subscriptions, monitor events, call methods, read history, and manage nodes. You may also start an optional local OPC UA server that listens for incoming connections on a configured port. These network features are the core functionality of the Application and are used solely for OPC UA protocol communication with the servers or clients you select. No personal data is transmitted to external servers operated by the Service Provider.
Do third parties see and/or have access to information obtained by the Application?
Since the Application does not collect any personal information for the Service Provider, no personal data is shared with third parties by the Service Provider. OPC UA communication data stays between your Mac and the OPC UA endpoints you connect to or allow on your network.
What are my opt-out rights?
You can stop all collection of information by the Application easily by uninstalling it. You may use the standard uninstall processes as may be available on your Mac or via the Mac App Store.
Children
The Application is not used to knowingly solicit data from or market to children under the age of 13.
The Service Provider does not knowingly collect personally identifiable information from children. The Service Provider encourages all children to never submit any personally identifiable information through the Application and/or Services. The Service Provider encourage parents and legal guardians to monitor their children's Internet usage and to help enforce this Policy by instructing their children never to provide personally identifiable information through the Application and/or Services without their permission. If you have reason to believe that a child has provided personally identifiable information to the Service Provider through the Application and/or Services, please contact the Service Provider ([email protected]) so that they will be able to take the necessary actions. You must also be at least 16 years of age to consent to the processing of your personally identifiable information in your country (in some countries we may allow your parent or guardian to do so on your behalf).
Security
The Service Provider is concerned about safeguarding the confidentiality of your information. However, since the Application does not collect any personal information for the Service Provider and all app processing happens locally on your device, there is no risk of your personal data being accessed by unauthorized individuals through the Service Provider. You are responsible for the OPC UA servers and networks you choose to connect to.
Changes
This Privacy Policy may be updated from time to time for any reason. The Service Provider will notify you of any changes to their Privacy Policy by updating this page with the new Privacy Policy. You are advised to consult this Privacy Policy regularly for any changes, as continued use is deemed approval of all changes.
This privacy policy is effective as of 2026-08-04
