What Personal Data We Collect and Why

When You Navigate Our Website

The Website collects some data when a User calls up the Website, which are stored in server log files. Such data include the IP address of the User, the browser type and version, the operating system, the referrer and any data that the User’s browser sends as part of the navigation activity on the Website. This data is needed to deliver the content of the Website correctly, to provide law enforcement authorities with the necessary information in case of a cyber-attack, and to perform anonymous statistical analyses.

When You Contact Us

If a User contacts Lightstreamer via email or via a contact form, the personal data transmitted by the User on a voluntary basis are automatically stored and used for providing answers to the User and for any subsequent communication.

When You Subscribe to Our Newsletter

On the Website, users are given the opportunity to subscribe to our newsletter, to stay informed on news regarding Lightstreamer. An email will be sent to the email address registered by the User to confirm the email address, as part of a double opt-in procedure. The personal data collected when subscribing to the newsletter are: email address, first name (optional), last name (optional), and IP address.

The newsletter contains so-called tracking pixels. A tracking pixel is a miniature graphic embedded in such emails, which allows a statistical analysis of the success or failure of online marketing campaigns. Based on the embedded tracking pixel, the Data Controller and Data Processor may see if and when an email was opened by a User and which links in the email were called up by the User.

The subscription to our newsletter may be terminated by the User at any time, by following a link provided in each newsletter. It is also possible to communicate the revocation to Lightstreamer via email or registered mail.

When You Register to Our Forum

The Website provides a discussion forum where registered users can post messages. An email will be sent to the email address registered by the User to confirm the email address, as part of a double opt-in procedure. The personal data collected when registering to the forum are: email address, IP address, username, and password. Users can provide any further personal data on a voluntary basis by filling in their public user profile on the forum. Such personal data are not required to use the forum. Please remember that any information you disclose in the forum becomes public information and we are not responsible for the use of any information that you choose to post to our forum.

We use Google reCAPTCHA for spam protection when registering. This service analyzes the traffic of this Website, potentially containing Users’ Personal Data, with the purpose of filtering it from parts of traffic, messages, and content that are recognized as spam. The use of reCAPTCHA is subject to the Google privacy policy ( and terms of use (

When You Chat on Our Site

The Website uses Now4real to enable visitors to chat with each other in real time. Lightstreamer acts as an autonomous Data Controller with regard to the processing of chat data (please see to know the details of what personal data Lightstreamer, which is the Publisher, processes). We can access chat data with a maximum time span of 12 months on a rolling basis and we use such data for the same purposes and with the same means applicable in the case of information made publicly available on the Internet by anyone. Please see the Now4real’s terms of service ( and Now4real’s privacy policy ( for more details.

When You Comment on Our Blog

The Website provides a blog, which allows Users to publish comments below each blog post. The commenting system is not provided by Lightstreamer but by a third party called Disqus, a US-based company. Registration to Disqus, login to Disqus, and any personal data collected as part of the Disqus experience are directly and completely managed by Disqus. Lightstreamer does not act as a Data Controller for the personal data managed by Disqus. Please see the privacy policy of Disqus, available on their site (, before using this service.

When You Use Our Online Demos

The Website contains some technology demonstrations (called “demos”). Some of the demos can be used online, directly on the Website’s pages, while others need to be downloaded on User’s mobile devices or computers. When the User uses a demo, we store the IP address of the User in server log files and we might enable remote logging for diagnostic purpose, but no personal data, except for the IP address, are reported.

Some of the demos include chat features. For all the chats, the IP address of the User is collected and stored together with the published chat message, to provide law enforcement authorities with such data if required. In some chats, the IP address is publicly displayed, if this is a specific feature of that type of chat. Please remember that any information you disclose in the chat becomes public information and we are not responsible for the use of any information that you choose to post to our chats.

Some demos provide push notifications. If the User makes use of them, a unique token identifying the mobile device, the computer, or the browser is stored on an internal database. No personal data, not even the User’s IP address, is associated with the token, and it is stored only for the purpose of sending push notifications. The token may be shared with third-party services, such as Google Firebase or Apple APNs, again only for the purpose of sending push notifications. When the User unsubscribes or disables push notifications, either via the demo’s controls or via the device or browser settings, the token is automatically deleted with a calendar week.

How We Process Personal Data

The Data Controller declares and guarantees that the Personal Data provided by the User will be treated with the strictest confidentiality and protection, also ensuring that appropriate security measures, of both technical and organizational nature, will be taken aimed at preventing access, disclosure, accidental or improper alteration, unauthorized loss or destruction of Personal Data. Personal Data may be processed by the Data Controller in manual, paper or electronic form. Specific security measures are observed by the Data Controller to prevent data loss, illicit or incorrect use and unauthorized access.

Our IT infrastructure is based on cloud services provided by third-party companies, which act as Data Processors on behalf of Lightstreamer. Such Data Processors are all GDPR compliant and are based either in EU or in US (with the Standard Contractual Clauses in place).
