About Citizen

Citizen's vision is to provide a safer, more legitimate internet. One where individuals control their own data, and businesses are granted deeper information direct from their customers.

Our model is to never resell or pass on personal data without consent. To guarantee this, we use cryptographic tokens, so we cannot see or sell our customer’s data.
