If you accept analytics cookies, we collect anonymised usage data via Google Analytics 4 (property G-YQCLY3MNTP). This includes pages visited, session duration, device type, and approximate country. GA4 is loaded only after you accept cookies.
AI feature data
When you use AI-powered features (ad generation, pricing suggestions), the listing text you provide is sent to an AI language model provider to generate suggestions. We do not store your prompts beyond the current session.
Technical logs
