We bind each subprocessor to data protection terms consistent with our [Data Processing Agreement](/data-processing-agreement). No third-country transfer takes place, neither from our systems nor from those of our subprocessors. The Data Privacy Framework column shows whether a US-based subprocessor is listed on the [EU-US Data Privacy Framework](https://www.dataprivacyframework.gov/); for EU-based entities it doesn't apply ("entfällt"). | Kategorie | Unternehmen | Adresse | Art der Dienstleistung | Verarbeitungsstandort | Data Privacy Framework | | ---------- | ---------------------------------- | --------------------------------------------------------------- | --------------------------------------------------------- | ------------------------------ | ------------------------------------------------------ | | Hosting | Amazon Web Services EMEA Sàrl | Avenue John F.

The table below describes the role each one plays in the flow of that data. | Subprocessor | Role in the data flow | | --------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Amazon Web Services | Provides managed database hosting and object storage in `eu-central-1` (Frankfurt), where all application data is stored long-term: website knowledge copies, employee-uploaded files, conversation and user data, and configuration. Also runs model inference through AWS Bedrock. | | Hetzner | Hosts the servers in Nuremberg and Falkenstein that run the API and other botBrains-operated services. | | DigitalOcean | Provides an in-memory database in Frankfurt for caching and scheduling asynchronous processing. Cached data may temporarily include customer data. | | Vercel | Serves static HTML, JavaScript, CSS, and images for the chat widget (chat.botbrains.io) and the web app (platform.botbrains.io) over a global CDN, processing only the user's IP address. | | Modal | Provides the isolated execution environment (sandboxes), running in the EU region. | | Microsoft Deutschland | Provides AI models. Inference runs in Sweden and France for capacity reasons; botBrains keeps the option to add further locations within the EU. | | OpenAI Ireland | Provides AI models under an Enterprise Zero Data Retention agreement with EU data residency, so both storage (none, under ZDR) and inference stay within the EU. See [ZDR](https://developers.openai.com/api/docs/guides/your-data#zero-data-retention) and [EU data residency](https://developers.openai.com/api/docs/guides/your-data#data-residency-controls). | | Sentry | Captures application errors in the API and chat widget and alerts us to anomalies. EU region. | | Better Stack | Collects logs and metrics for our applications and alerts us to anomalies. EU region, with headquarters in Poland. | | Langfuse | Records AI model inputs and outputs, including the customer data in those conversations, for tracing and cost control. | | PostHog | Tracks chat-user interaction after a conversation begins and platform-user (employee) interaction to monitor product issues and improve the interface. |
