You keep ownership of the data you upload to W&B, but you give W&B a worldwide license to use, copy, and store your data as needed to run their service.
Your proprietary ML training data, experiment logs, and model outputs uploaded to W&B are subject to a broad worldwide license that W&B can exercise to the extent they determine is necessary for service delivery, without clear restrictions on subprocessor use.

Compare across platforms →While you retain ownership, the license grant is broadly worded and the scope of 'as necessary to provide the Services' is not precisely defined, meaning W&B has significant latitude in how it handles your data.
(1) REGULATORY FRAMEWORK: The customer data license provision must be read in conjunction with GDPR Art. 28 (processor obligations) and CCPA §1798.100 (right to know how personal data is used). The grant of a 'worldwide' license raises questions about international data transfers subject to GDPR Chapter V transfer restrictions and SCCs. Proprietary AI training data may also be subject to trade secret protection under the Defend Trade Secrets Act (18 U.S.C. §1836), and overly broad license grants could be argued to constitute a waiver of trade secret protections.
