Read our security modelDoes Lens upload my captured traffic?
No. Saved sessions, request and response bodies, transactions, and WebSocket payloads stay on your Mac.
What about certificate-pinned apps?
Pinned apps may reject Lens’s locally generated certificate. Use a debug build or disable pinning for development traffic.
