Privacy Policy

This privacy policy sets out how Atheist Alliance International (AAI) will use and protect any information that you provide as part of Atheist Census.

If you have any questions or concerns after reviewing this privacy policy please contact us.


What we collect

The information collected by Atheist Census is your demographic information (the answers to the six Atheist Census questions) and email address.


What we do with your information

The aim of Atheist Census is to collect demographic data from and count the world's atheists. As such, the demographic information collected will be held by AAI in perpetuity. In an aggregated form that does not identify any individual, Atheist Census data is available through the website and AAI may provide such data to groups or individuals.

An email address will be associated with each set of census responses solely for data validation purposes. An email will be sent to your email address so that you can validate your data for Atheist Census. Data will not be included in Atheist Census unless it has been validated. Once data is validated each email address is retained in a "hashed" (one way encrypted) format to protect data integrity, so that even if the Atheist Census database is compromised it will not be possible for your email address to be de-coded. If the data is not validated within 24 hours the email address and all associated data is deleted.

AAI will not share your email address with any person or organisation outside Atheist Census, use the email address for any purpose other than data validation and will not contact you after your data has been validated, unless you initiate contact with Atheist Census.



We are committed to ensuring that your information is secure. In order to prevent unauthorised access or disclosure, we have put in place suitable physical, electronic and managerial procedures to safeguard and secure Atheist Census information.
