Will Trackdrop share my contacts with other labels?

No. Trackdrop will never share your contacts with other users. 

Your audience list and the contact information included are exclusively associated with your organization.

The only users who can view, add, or remove your contacts are those that you invite to join your organization, including  the account owner, admins, and team members.
