# BigBlueButton Privacy Policy

The **BigBlueButton Privacy Policy** defines the legal and technical framework for processing personal data when using the BigBlueButton (BBB) activity within [[moodle]] at the Universität Greifswald.

## Data Processing Framework

### Collected Data
The system collects different types of data depending on the usage mode:
- **Technical/Usage Data:** User-ID, IP addresses, URLs, and audio/video streams.
- **Recording Data:** Chat text data is captured specifically when a session is recorded.

### Legal Justification
The processing of data is justified under the following [[gdpr-compliance]] articles:
- **Standard Operation:** Art. 6(1)(e) GDPR (Public Interest) or Art. 6(1)(b) GDPR (Contractual/Employment obligations).
- **Recordings:** Art. 6(1)(a) GDPR (Explicit Consent).

## Retention and Deletion
The URZ implements a strict deletion schedule to minimize data footprint:
- **Technical Logs:** Maximum 7 days.
- **Volatile Data:** Session-specific files and presentations are deleted immediately upon session termination.
- **Recordings:** Standardly deleted 6 months after the current semester ends. Extensions up to 2 years are possible with approval from the Data Protection Officer.

## Usage Restrictions
To ensure compliance with copyright and data protection laws, recordings are restricted to playback within [[moodle]]. Downloading, duplicating, or distributing these recordings is prohibited.
