Information We Collect
Automatically collected. We use Vercel Analytics and PostHog to collect anonymous usage data (page views, device type, country, feature interactions). This data does not identify you personally. PostHog analytics cookies are only set with your explicit consent. PostHog stores data in the EU (Frankfurt).
AI Watch Check tool. When you use the AI Watch Check tool, the photos and text you submit are sent to our AI service provider (OpenAI, via Vercel AI Gateway) for real-time analysis. We take a zero-storage approach:
- Photos are processed in memory and never saved to any database, file system, or log.
- Analysis results are streamed directly to your browser and not retained on our servers.
- Any text you provide (purchase details, notes) is discarded once the response is delivered.
- There are no user accounts — we have no way to link a session back to you.
Once you close or refresh the page, all data from your session is gone.
