Our Data Transparency Principles
You deserve to know exactly where your data comes from and how we handle it
Every email comes with a verified public source.
All contacts found via Domain Search include details about where and when we discovered them. In the Email Finder, we clearly indicate whether a result is verified or predicted. You always know the origin of your data no black boxes.
Stale data is automatically removed.
After six months, we remove any contact or company information that no longer has a valid public source. Before removal, we flag it with a Removed label so you are never surprised. This keeps our B2B email database consistently fresh and reliable.
Data subjects have full control over their information.
Anyone can remove their contact information instantly by claiming their email address. Owners can edit any field associated with their profile. Upon a deletion request, the email and all related data are permanently and irreversibly removed.
Website owners decide how we index their pages.
Our crawler identifies itself with a clear User-Agent and fully respects the robots.txt standard. If you don't want us indexing your site, simply disallow our crawler we'll stop immediately.
