What data AWS Lambda collects
Your privacy policy must disclose each of the following data types when you use AWS Lambda.
When does AWS Lambda trigger privacy obligations?
Data flows that trigger obligations
AWS Lambda begins processing data the moment a function executes. Every invocation sends the request payload, headers, and context metadata to AWS servers in your chosen region. If your function logs anything—errors, user IDs, request details—CloudWatch captures and stores that data by default. This happens immediately and automatically; there is no "opt-in" moment.
Which regulations apply
GDPR (if you have EU users): AWS Lambda triggers Article 6 (lawful basis) and Article 28 (processor obligations) requirements immediately. You must have a Data Processing Agreement (DPA) with AWS before any function runs. Article 5(1)(a) requires explicit legal ground for processing; Article 5(1)(f) requires security safeguards—AWS's certifications (SOC 2, ISO 27001) help satisfy this, but you remain accountable.
CCPA (California residents): If you collect personal information via Lambda functions (IP addresses, user IDs in logs, request metadata), CCPA Section 1798.100 gives users right-to-know obligations. You must disclose what data is collected.
