When you sign up, we collect your email address and password (managed by AWS Cognito). When you connect your Klaviyo account, we store your API key in encrypted form using AWS Secrets Manager.
When you run a personalization, we temporarily read customer profile data and purchase history from your Klaviyo account to generate personalized content. This data is processed in real-time and is not stored on our servers.
Your data is used solely to generate personalized email content and write it back to your Klaviyo profiles. We do not sell, share, or provide your data to any third parties. We do not use your data to train AI models.
Content generation is powered by AWS Bedrock (Anthropic Claude). AWS Bedrock contractually guarantees that inputs and outputs are not used to train or improve foundation models. Your customer data stays private throughout the generation process.
All data is encrypted at rest and in transit. Your Klaviyo API key is stored in AWS Secrets Manager with strict access controls. Account data is stored in AWS DynamoDB. All infrastructure runs in AWS US-East-1.
Customer profile data from Klaviyo is read, processed, and written back in real-time. We do not retain copies of your customers' data after processing.
