The following authorizations are required to implement the functions in the app:
 

• Location (Android/iOS): For location-based settings and to collect SSID information during the pairing process.
• Device Storage / Photos & Media (Android/iOS): To save logs or other data necessary for operation.

• Device Information (Android/iOS): Access to device identifiers (e.g., IDFA, Android ID, IMEI, MAC address) to ensure account security and system operation.

On this page we inform you about the privacy policy of the Micro RE App for Android and iOS ("App"). The App is offered by LEDVANCE GmbH, Parkring 1-5, 85748 Garching near Munich, Germany ("LEDVANCE GmbH", "we" or "us").

Unless otherwise stated in this privacy policy the following applies:
 
1. Scope of processing

The App is used for the technical control of photovoltaic systems and provides direct technical support for users. Multi-user access is enabled.

2. Control of smart devices and information associated with these devices
 
With this App, you can control various micro-inverters and associated photovoltaic systems.
Depending on which devices you control with this App, different data may be affected.
In particular information about the photovoltaic system such as the system name, configuration information, generation data, and system alarm data.
 
In some cases (e.g. if they are linked to a user account), this data may be assigned to you or third parties. If you use third-party data in the app, you are responsible for obtaining the appropriate usage rights.
A list and detailed description of the data used with our smart devices can be found on our website here.

3. Personal reference and user account

When the app is installed, a unique ID is generated and stored on Ledvance servers. This ID cannot be linked to a specific person unless the user registers with their email address.

4. Purpose of processing in general

The general purpose of processing personal data with the App is to allow users of the App to have technical control of their photovoltaic systems and to provide technical support by LEDVANCE.
 
5. Legal basis for the processing of personal data in the Micro RE App in general

Where the app uses personal data this is necessary for the execution of the user contract, which forms the basis for the use of the app and the related services. This includes processing in order to safeguard your data and error detection as well as supporting users. Therefore the legal basis for the processing of your personal data is Art. 6 (1) (b) GDPR.

There may be situations where we do not only use your data to fulfil the contract (e.g., to fulfil obligations to public bodies). The legal basis in those cases is either your consent or, depending on the situation, another legal basis within the meaning of Art. 6 GDPR.

In some cases the processing of technical data serves to safeguard a legitimate interest of our company in providing a functional application for users and is therefore based on Art. 6 (1) (f) GDPR as the legal basis for the processing.

6. Duration of storage
 
Your personal information will be retained for as long as necessary to fulfill the purposes described in this Privacy Policy or as required by law. In addition, data will not be deleted if and as long as we have an overriding legitimate interest in doing so (e.g. to protect our rights or defend ourselves against legal claims).
 

The following data is processed when the app is started. The servers automatically collect and store information in so-called server log files, which your device automatically transmits when you start the app. The stored information is:
 

• Device model, operating system, location, time zone, camera, Bluetooth;
• User email address, login password;
• Inverter-related data: voltage, frequency, current, power, energy generation, temperature, signal strength, and firmware version. Third parties do not have access to server log files. This data is not merged with other data sources.

The following data is processed when using a user account:
 

• Username
• Password
• E-Mail-address
• Phone number (only applicable to Chinese user)

Deleting a user account will result in the deletion or anonymization of all associated data, unless legal retention obligations apply.
 
Regular users can delete their accounts themselves by going to Me > Settings > Account & Security in the app and tapping "Account Cancellation" (which will permanently delete the account)
 
Please note that certain functions require a valid user account. If such accounts are deleted, these functions will no longer be available.

1. Description and scope of data processing

Each time our app is accessed, our system automatically collects data and relevant information from the computer system of the device.
 
The following data is collected:
 

• Browser type and version used
• The user's operating system
• The IP address of the user
• Date and time of access
• language settings, time zone, app-version

This data is stored in the log files of our system. This data is not stored together with other personal data of the user.

2. Purpose of data processing

The temporary storage of the IP address by the system is necessary for the delivery of the app to the device of the user. For this purpose, the user’s IP address must be kept for the duration of the session.

The storage in logfiles is done to ensure the functionality of the app. The data is also used to optimize the app and to ensure the security of our IT systems. An analysis of the data for marketing purposes does not take place.

3. Legal basis for data processing

The processing of the aforementioned data is necessary for the execution of the user contract, which forms the basis for the use of the app and the related services.  Hence the legal basis for the processing of your personal data is Art. 6 (1) (b) GDPR. In addition for the aforementioned purposes, our legitimate interest lies in the processing of data in compliance with Art. 6 para. 1 s. 1 lit. f GDPR.

4. Duration of storage

The data will be deleted as soon as it is no longer necessary for the purpose of its collection. The session is complete when the collection of data for the provision of the app is accomplished.

If the data is stored in log files, this is the case after five days at the latest. Storage beyond this is possible. In this case, the IP addresses of the users are deleted or alienated so that an assignment of the calling client is not possible.

5. Objection and erasure

Pursuant to Article 21 (1) GDPR, you have the right to object at any time to the processing of personal data concerning you on the basis of Article 6 para. 1 lit. f GDPR (data processing to protect a legitimate interest), this also applies to profiling based on this provision. Whether or not the objection is successful, shall be determined through the balancing of interests.
The user is given the opportunity to object to the processing by e-mail request.
In order to do so, please send an email to: privacy@ledvance.com

Our app uses the built-in error and crash reporting features provided by Apple (for iOS devices) and Google (for Android devices) to help us identify and fix technical issues. When the app crashes or encounters a serious error, anonymized technical information is collected. This may include:
Device type and operating system version, App version, Time and circumstances of the crash, technical details such as stack traces.
This information is automatically collected by your device’s operating system and, with your consent, transmitted to Apple or Google. We, as the app developer, receive access to anonymized crash reports through Apple’s and Google’s developer platforms. These reports do not contain any information that directly identifies you as an individual. We use this data solely to analyze and improve the stability and performance of our app. The processing of this data is based on our legitimate interest in maintaining and improving the technical functionality of our app (Art. 6(1)(f) GDPR).
You can control whether diagnostic and usage data is shared with app developers in your device’s privacy settings.
