- Use data: a non-exclusive, non-transferable licence to use the results for internal purposes: checking counterparties, due diligence, B2B selling to firms and completing your own records or, if you are a consumer, for your personal use [...] The licence does not include the right to resell, sublicense, rent or redistribute to third parties the Leadgen service, our compilation or the figures we derive, nor to build a competing database on them, any such redistribution needs our written agreement. You may publish, with source attribution and a link to leadgen.adrianhomelab.com, excerpts of up to 50 firms in a report or article [...] You may not use the results for: (a) decisions taken solely by automated means about an individual that produce legal effects concerning them or similarly significantly affect them (GDPR art. 22), including automated decisions on their eligibility for credit, insurance, employment, housing or debt collection, (b) tracing, surveillance or locating an individual, including skip-tracing, (c) re-identifying individuals from apparently anonymous data, (d) combining data about individuals with social networks or other sources to build profiles of those individuals, outside the business relationship with their firm, (e) building, on our compilation, a database or service that competes with Leadgen [...] do not re-publish the dataset in bulk, ask for bulk access instead
