| Keep data | no limit |
| Use data | ZelNum is provided for the following purposes only: CRM list cleaning and contact record quality checks. Marketing list hygiene: suppressing invalid, duplicate, unreachable, or wrong-channel records inside lists you are already allowed to process. Fraud, abuse, and risk review of signup, lead, or applicant records. Internal data-quality and compliance support for records you hold a lawful basis to process. Developer integration of validation into your own product through the API. [...] You must not use ZelNum to: Send, or prepare to send, unsolicited messages, spam, or bulk cold outreach of any kind. Harass, threaten, stalk, embarrass, or harm any person, or to find people who do not want to be found. Check numbers or identifiers for which you do not hold a lawful basis and any required consent. Build, resell, or distribute a database of people, or of their platform memberships, as a data broker. Circumvent platform rules, rate limits, or access controls, or resell raw access to the service. Impersonate ZelNum, present results as identity proof, or generate reports that claim identity or consent has been verified. Break any law that applies to you, including data-protection and anti-spam rules such as the GDPR, the ePrivacy Directive, or local equivalents. Access or use the service from, or on behalf of persons or entities in, jurisdictions subject to comprehensive sanctions, or in violation of applicable export-control rules. [...] You must not use ZelNum, or allow anything built on ZelNum to be used, for any of the following: Resale and redistribution of results. Passing ZelNum output to another party as a product, dataset, or service — whether resold, sublicensed, white-labelled, bundled into your own offering, or exposed through an API, dashboard, or file that third parties can query. Using results inside your own business, and inside software you operate for your own customers on their own records, is permitted, trading the output itself is not. Eligibility decisions about people. Using results as a factor in employment, credit, insurance, tenancy, education, or benefits decisions, or as identity verification or a background check. [...] By submitting a phone number, email address, or other identifier, you confirm that you hold a lawful basis for processing it and that you have obtained any consent or permission required by law or by the relevant platform. |
