Privacy Policy

This Privacy Policy applies to 4xlabs's website, including pages for marketing, announcements, publications, and our job board. It applies to visitors, prospective collaborators, and job applicants who interact with us online.

Separate notices or agreements may apply to employees, research participants, and partners who receive data from us under a contract. Where a signed agreement conflicts with this policy, the agreement controls.

4xlabs operates exclusively in the United States. We do not do business with, and we refuse service to, persons located outside the United States. This website is directed solely to U.S. audiences, and we do not knowingly collect personal information from individuals located outside the U.S.

If we learn that we have collected personal information from a person located outside the U.S., we will delete it.

We collect the following categories of information:

• Contact information you provide, such as your name, email address, organization, and the contents of your message when you contact us or request information.
• Application information you submit through our job board, such as your résumé/CV, work history, education, and contact details.
• Technical information collected automatically, such as IP address, browser type, device type, referring pages, and pages visited, through server logs and analytics tools.
• Cookie and similar technology data, described in the Cookies section below.

We use the information we collect to:

• Operate, maintain, and secure the website.
• Respond to inquiries and requests from prospective collaborators, customers, and partners.
• Evaluate job applications and communicate with applicants.
• Publish announcements and research communications you have asked to receive.
• Understand how the site is used and improve its content and performance.
• Comply with law, enforce our terms, and protect our rights, personnel, and property.

We do not sell or rent personal information, and we do not share it for cross-context behavioral advertising. We share information only with:

• Service providers that host, operate, and support our site and communications, bound by contract to process information only on our instructions. Our site is hosted on Railway, which maintains a SOC 2 Type 2 attestation.
• Professional advisers and auditors, under confidentiality obligations.
• Authorities, where required by law or to protect rights, property, or safety.
• A successor entity in connection with a merger, acquisition, or asset sale, where permitted by law.

We use cookies and similar technologies for essential site functions and, if enabled, for aggregate analytics about site usage. We do not use cookies for advertising or to build cross-site profiles.

You can control cookies through your browser settings. Disabling essential cookies may affect site functionality.

Depending on your U.S. state of residence, you may have rights regarding your personal information, including the right to know what we collect, to access and delete it, to correct inaccuracies, and to opt out of its sale or sharing. We do not sell or share personal information as those terms are defined under state privacy laws, so no opt-out mechanism is required.

To exercise a right, contact us at [legal@4xlabs.com]. We will verify your request as required by law and respond within the timeframes applicable to your state. We will not discriminate against you for exercising your rights.

We keep personal information only as long as needed for the purposes described in this policy, to comply with legal obligations, resolve disputes, and enforce agreements. Inquiry records are retained for up to 24 months; job application records are retained for up to 12 months unless you ask us to keep them longer or law requires otherwise.

We use administrative, technical, and physical safeguards designed to protect personal information, including hosting with a SOC 2 Type 2 attested provider, transport encryption (HTTPS), access controls, and least-privilege practices. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

This site is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us personal information, contact us and we will delete it.

We may update this policy as our practices change. The “Last updated” date above reflects the current version. Material changes will be highlighted on this page.
