Vendor profile

Langfuse: where is customer data stored and processed?

Langfuse, with headquarters in Germany and owned by ClickHouse, Inc. (USA), stores and runs customer data mainly on AWS in Ireland for EU customers, and the customer chooses the region. Backups are stored in Ireland, and Postgres backups are replicated to Frankfurt, Germany, which is not confirmed. AI features use AWS Bedrock in the selected region, and kapa.ai processes support data in the USA. Support data is handled in the USA through Salesforce, Pylon, Google, Waypoint and GitHub, while several ClickHouse entities in other countries provide technical support without stated processing location. The data processing addendum is read but does not state where data is stored, so the storage location is taken from other sources in the vendor's documentation.
