## Data

- Freshness: live
- What it checks: format, mail servers, disposable domains, role addresses, mailbox
- Keep data: while your subscription is active, after it ends, exported records only for people and businesses with whom you have by then established your own relationship, all other Lead Data deleted within 30 days
- Use data: a limited, non-exclusive, non-transferable, non-sublicensable and revocable licence to access the Database and use Lead Data for your internal business-to-business prospecting: identifying businesses, and people in their business roles, who may be interested in your own products or services, and contacting them about those products or services. You must not, and must not allow anyone else to, use Lead Data or the Database to: Resell or re-list it: as a standalone dataset, bundled with other data, or repackaged as a lead list or database product for anyone else. Provide enrichment for hire: appending, matching, or enriching a third party's records as a service, whether paid or not. Append it to a third-party database: merging it into someone else's contact database, CRM instance, or dataset that you don't control, or handing it to a data broker. Build a competing product or dataset, or systematically extract, download or copy all or a substantial part of the Database [...]. Train or evaluate AI: use it to train, fine-tune, benchmark or evaluate any AI or machine-learning model, or add it to any dataset used for that. Market to consumers: contact people in a personal or household capacity rather than their business role. Make eligibility decisions: decide or help decide anyone's eligibility for credit, insurance, employment, housing, tenancy, education or any government benefit [...]. Profile sensitive characteristics: infer or record anyone's health, ethnicity, religion, political opinions, sexual orientation, trade union membership or any other special category or criminal offence data, or discriminate unlawfully against anyone. Harass or locate people: stalk, harass, threaten or intimidate anyone, locate or track an individual, or publish anyone's details. Surveil or campaign: carry out surveillance, investigations into individuals, or political campaigning.
