Your individual survey answers are never used for advertising and are never sold for marketing purposes.
Your name and contact information will always be removed to protect your privacy. This means your specific answers are never identifiable or traceable back to you.
Sharing of survey data with external research partners is a separate matter and may only happen if you have explicitly provided research consent for the Individual Data Sharing consent. In such cases the data will be shared deidentified.
See our FAQ: What will you do with the information I provide in the surveys? for further details.
