Weights & Biases Privacy Policy

This document explains what data Weights & Biases collects about you, how it uses and shares it, and what protections are in place. Your data — including everything you submit through the Services — may be used to run and improve the platform and to target you with marketing across different sites and apps. Weights & Biases does not sell your personal data, and it does not use automated systems to make decisions about you that have major legal or practical consequences.

This Privacy Policy establishes the conditions under which Weights & Biases collects, uses, retains, and shares personal data in connection with its Services and Sites. Weights & Biases collects a broad range of user-generated content — including messages, support communications, Slack interactions, and tool inputs and outputs — as well as identification and, where applicable, biometric and video surveillance data from facility visitors. Customer data is used to operate, analyze, debug, and improve the Services, and also for targeted and cross-context behavioral marketing purposes. Personal data may be shared with CoreWeave and its current or future parent, subsidiary, and affiliated companies, including for cross-context behavioral advertising, though Weights & Biases commits that it does not sell personal data. Data retention is limited to what is necessary for the policy's stated purposes unless law requires or permits a longer period, and automated decision-making or profiling producing legal or similarly significant effects on users is not performed.

Weights & Biases collects a wide range of personal data, including all content you submit through its Services and Sites, and uses that data not only to provide its Services but also for targeted and cross-context behavioral marketing. If you visit a Weights & Biases office or data center, biometric data and video surveillance footage may also be collected. Your data may be shared with CoreWeave and affiliated companies, including for behavioral advertising across platforms. Weights & Biases does not sell personal data and does not perform automated decision-making with legal or significant effects on you. Where applicable law requires it, Weights & Biases recognizes a Global Privacy Control signal from your browser as a valid opt-out from the sale or sharing of your personal information — setting that signal in your browser is one concrete action you can take.
