Cognism is GDPR-compliant B2B sales and marketing lead generation platform, providing B2B revenue teams with a blend of real-time company, people and event data to streamline prospecting, find and deliver new revenue. Cognism has a dedicated "Privacy Centre" opt-out form (linked from Section 9 of the privacy policy) to permanently erase your business-contact data from the Cognism Platform; the exact form URL is not printed in the policy text, so follow the "Privacy Centre" link on the policy page. You can also email privacy@cognism.com instead. Cognism says requests are handled within GDPR timeframes (30 days) and may ask for extra information to confirm your identity. Because Cognism rebuilds profiles from public sources like LinkedIn and third-party vendors, it is worth re-checking periodically, and note that customers who already downloaded your data are separate controllers with their own opt-outs.
