## Data

- Freshness: 90 days
- Keep data: no limit
- Use data: The Services are intended exclusively for use by businesses and the professionals who act on their behalf, in the course of a business activity. [...] Reasonable professional outreach (for example, a sales or recruiting message sent to a work contact about a legitimate business opportunity) is the intended use of the Services and is not itself a violation of this section. [...] use the Services solely for legitimate business purposes, on behalf of a company, and not for personal, family, or household purposes [...] not use, resell, embed, or otherwise make the Services or the Data available to, or accessible by, consumers, including as part of any consumer-facing website, app, or lookup tool [...] Use the Services for your own business account, do not resell, sublicense, or grant access to the API or dashboard to a third party without our prior written consent, except for your own employees and contractors acting on your behalf within a single workspace. [...] You may not copy, extract, or systematically redistribute the Data, in raw, enriched, or derived form, to a third party, or use it to build a database or dataset made available to a third party, whether for a fee or free of charge, without our prior written consent. [...] This does not prevent ordinary internal use: storing enriched records in your own CRM or data warehouse for your own business's use, or sharing a specific record with a colleague inside your organization as part of normal work, is not redistribution. [...] You may not use the Data: as a factor in determining an individual's eligibility for credit, insurance, employment, housing, or a government benefit or license, or for any other purpose that would make it a "consumer report" under the U.S. Fair Credit Reporting Act or an equivalent law in any jurisdiction, to infer or derive special categories of personal data (health, religion, political opinion, trade union membership, genetic or biometric data, or sexual orientation) about an individual, to make an automated decision about an individual that produces a legal or similarly significant effect on them, or in a way that discriminates against an individual on the basis of race, color, religion, national origin, sex, age, disability, genetic information, sexual orientation, gender identity, or any other characteristic protected under applicable anti-discrimination law. [...] Do not use the data to research, monitor, or contact an individual in a personal capacity unrelated to their professional or business role, including for personal background checks, dating-related purposes, or any form of harassment or stalking. [...] send unsolicited bulk email or engage in spam [...] Maintain a valid legal basis under applicable data protection law (including GDPR, where relevant) for your own processing of any personal data you obtain through the Services, and respond appropriately to any data subject request you receive in connection with that processing.
