Third-Party Services
The Service uses the following third-party services:
4a. Google MediaPipe (AI Model CDN)
- AI model files (WebAssembly, model weights) are loaded from jsDelivr CDN.
- CDN servers may record standard HTTP access logs (IP address, timestamp).
- After the model is cached in your browser, no further CDN requests are made.
4b. Google AdSense (Advertising)
The Service may display Google AdSense advertisements to cover operating costs. Google AdSense uses cookies and data as follows:
