What is Cognism?

Cognism is a B2B global sales-intelligence platform providing business contact data (emails, mobile numbers), company profiles, and intent data, with phone-verified mobile data and DNC scrubbing.

What data Cognism has on you

Cognism compiles professional contact data that sales teams, recruiters, and marketers buy access to. Here is what a typical profile includes:

• full name
• work email, personal and work where available
• mobile/direct dial phone, landline and mobile, sourced from commercial providers and public records
• job title
• employer
• work history
• company data
• intent data
• location

Not every profile contains all categories. Depth depends on what public records exist in your jurisdiction and how much commercial data has been linked to your identity. For most adults with any public record history, Cognism has enough to paint a detailed picture.

How to opt out of Cognism: step by step

1. Go to cognism.com/data-opt-out (or click 'Opt Out' in the footer under 'Your Data')
2. Enter your first name, last name, work email, company name, country (and state)
3. Complete the CAPTCHA and click 'Opt Me Out'
4. For full data-subject rights, use Cognism's Privacy Centre to submit a request and verify via the email Cognism sends (only verified requests are processed)

How long does Cognism removal take?

After you complete the opt-out, Cognism typically processes removals within 120 hours (~5 days); up to 30 days for formal DSARs. By broker standards, that is relatively fast; many sites take 7 to 45 days.

The catch: your data comes back

The most important thing to understand about Cognism removal: it is temporary.

Cognism removes you from the data asset and lists you to customers as opted-out; data may be recollected from public sources. Customers must action opt-outs in their own systems.

This is not unique to Cognism. Every data broker works this way. Your opt-out removes one listing. It does not stop the data pipeline. The only way to stay off permanently is to repeat the process every few months yourself, or use a service that detects re-listings and re-submits automatically.

What Cognism's opt-out does not cover

• Other brokers are not affected. Removing yourself from Cognism does nothing to Kaspr, or the dozens of other sites where your data is exposed. Each requires its own opt-out.
• Cached copies may persist. Google and other search engines may cache your Cognism profile for days or weeks after it is removed. Use Google's content removal tool to request de-indexing.
• Multiple profiles may exist. If you have lived in multiple states, changed your name, or have multiple phone numbers, Cognism may have built separate profiles for each variation. Search and opt out of each.

Tips for a successful opt-out

Use a dedicated email. Use an alias or a separate account for removal requests. Keeps your primary inbox out of Cognism's system and keeps confirmation emails organized.

Search every angle. Do not just search by name. Try phone number and email too. You may have more than one listing.

Document the request. Screenshot the confirmation page and save the confirmation email. Useful if you ever need to prove you requested removal.
