 We recommend using confidential text comparators when targeting users based on their sensitive data (like email address, name, etc).
 In this case, the feature flag evaluation is performed using the SHA256 hashes of the values to ensure that the comparison values are not exposed. This can cause an increase in the size of the config JSON file and the overall network traffic. Yet it is not recommended to use the cleartext version of the confidential comparators unless the increased network traffic becomes an issue.
