The clause delineates data ownership and establishes the scope of W&B's permitted use of customer data, limiting the license to service delivery purposes rather than permitting broader commercial use or exclusive rights.
The updated Terms of Service no longer include the previous statement that services would become inaccessible from certain locations starting September 1st, 2025. This removal means the geographic restriction that was previously announced in the agreement is no longer formally stated in the current terms. Users who were affected by or concerned about the prior restriction should review current documentation to confirm whether any geographic limitations remain in effect.

"As between the parties, Customer owns all right, title, and interest in and to the Customer Data. Customer hereby grants W&B a non-exclusive, worldwide, royalty-free license to use, copy, store, transmit, and display Customer Data solely as necessary to provide the Services to Customer and as permitted by this Agreement and the Privacy Policy.— Excerpt from Weights & Biases's Weights & Biases Terms of Service
(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.
