As part of our privacy measures, we implement certain rules designed to avoid the unintentional collection of PII such as email addresses, social security numbers, credit card numbers, login information etc. Such rules are based on known field types, parameters, values and algorithms but they are not foolproof and hence the Software & Services may sometimes, unintentionally, collect unwanted information.
