Intellectual Property — Customer Data Ownership and W&B License

Medium severity
Share 𝕏 Share in Share 🔒 PDF

What it is

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.

Consumer impact (what this means for users)

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.

What you can do

⚠️ These actions may provide transparency or partial mitigation but may not fully address the underlying issue. Effectiveness varies by jurisdiction and individual circumstances.
  • Export Your Data
    Log into your W&B account, navigate to your projects and datasets, and use the platform's export functionality to download your data before any service termination or if you wish to limit W&B's ongoing access to your uploaded content.

Why it matters (compliance & risk perspective)

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.

View original clause language
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.

Institutional analysis (Compliance & legal intelligence)

(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.
