Use of Third-Party Services — Stream Trust
RU4Meeting has integrated the Stream service (GetStream’s chat messaging platform) to provide users with reliable real-time messaging within the application. This integration introduces private and group chats as part of the app’s features, enhancing communication among users when organizing meetings and events. Using the ready-made Stream service instead of a custom-built solution offers scalable infrastructure, real-time message synchronization, and a rich set of features (such as notifications, typing indicators, attachments, etc.), with minimal development effort on our side. In short, Stream was integrated to ensure a stable, secure, and efficient chat environment in the RU4Meeting app.
For the integration, we used official Stream Chat SDK libraries on the client side.
Data Sent to the Stream Service
During integration, special attention was given to limiting the scope of personal data shared with the external Stream service. The user profile we send to Stream contains only the minimal information required for chat functionality:
User ID: An internal user identifier (e.g., numeric ID or UUID) is used as a unique marker in the Stream system. This ID is typically a pseudonym (we do not use an email or similar identifier) to reduce the possibility of revealing personal identity.
Name (nickname): A display name is forwarded to identify the message sender in the chat interface. It is recommended to use a first name or nickname, without a surname, to further protect privacy in cases where the app supports semi-anonymous users.
Profile picture (avatar): A URL pointing to the user’s profile picture or an uploaded image via the Stream API. This enables avatar display next to each message. The image is stored on the Stream side (if uploaded through them) or hosted on our server and referenced via a link.
No additional data is shared with the Stream service beyond these basic fields. Specifically, information such as email addresses, phone numbers, contact lists, or any other personal data is not visible to Stream through this integration. This ensures that the third party only receives the necessary data to provide the chat communication service.
The content of messages exchanged between users is transmitted through the Stream infrastructure, as this is the core of the messaging service. All messages, including any attachments (images, documents) sent in the chat, are transported and temporarily stored on Stream servers to enable delivery to channel members. Users are informed through the Terms of Use that their communication is facilitated via an external service.
Access Control: Access to data on the Stream platform is restricted to authorized requests using API keys and tokens. Each client can only read data from channels in which they participate.
Stream Trust, as a company, conducts regular security audits and holds SOC 2 Type II and ISO/IEC 27001:2022 certifications.
RU4M has signed a Data Processing Agreement (DPA) with the provider (Stream), outlining both parties’ obligations and responsibilities regarding user data protection. Accordingly, our application’s Privacy Policy has been updated with information about the use of the Stream service, ensuring transparency toward users (see the following section for a proposed wording).
Legal Basis for Processing:
Data processing via Stream Trust is carried out based on:
Execution of a contract (application functionality);
User consent (recording of video meetings);
Legitimate interest (service security and stability).
Data Transfer Outside the EU:
Data is not processed outside the EU. Stream Trust applies Standard Contractual Clauses (SCCs) and other measures in accordance with GDPR.
