Data Collection:
The app collects limited, anonymized data to support purchases and AI features.

AI Chat Interface (Optional): When you use the optional AI chat features, the content you submit like names, mailing addresses, and other text you type, your prompts, and any image you upload or place on an envelope, is securely routed through AIProxy and sent to OpenAI to generate your result.

Please do not enter anything into the AI features that you would not want transmitted for processing. If you do not use the AI chat features, this content stays on your device.
