Behavioral testing and visitor profiling generate detailed usage data that informs product optimization and user experience modifications. This data collection and analysis practice is a standard operational component of how Twilio monitors and refines its service delivery.
Interpretive note: The VWO implementation is confirmed in the page source code but the written privacy notice text was not fully available; the scope of written disclosure about VWO is unknown and this analysis is based on the technical implementation evidence alone.
The updated notice establishes more explicit disclosures of Twilio's Data Privacy Framework certifications and specifies the legal hierarchy governing data processing. Under the revised policy, the DPF Principles now take precedence if they conflict with other terms in the privacy notice. The updated language also clarifies your right to opt out of third-party disclosures (except to service providers acting on Twilio's behalf) and to opt out of uses that materially differ from original collection purposes. You can exercise these choices by contacting privacy@twilio.com.
View change record →The updated Privacy Notice now provides more detailed explanations of how Twilio collects and processes personal data, including explicit definitions of what constitutes personal data and descriptions of direct relationships (when you create an account or opt into communications) versus indirect relationships (when you are a customer of one of Twilio's customers). The revised language establishes that Twilio acts as a data controller and determines how and why personal data is processed, subject to applicable law. The notice states it aims to be transparent about data use and to explain how you can exercise your rights, but the change itself does not modify what data is collected, how it is used, or what rights or controls are available to you.
