Privacy, without the fine-print fog.
The Mobile View & Responsive Tester extension is built to work locally. It has no accounts, advertising, extension telemetry, remote application backend, website analytics, or session recording.
Your page URLs, responsive workspace, captures, recordings, annotations, saved sets, design references, and generated fix prompts stay on your device. Nothing is automatically uploaded to us.
What stays local
Workspace settings and preferences are stored through the browser's local extension storage. Screenshots, recordings, and prompts are created only after an action you initiate. Data leaves the extension only when you explicitly copy, download, open, or share it.
Browser permissions
Tab and scripting access let the extension open the page you selected inside the responsive workspace. Storage preserves local preferences and saved sets. Download and capture capabilities are used only for user-requested exports, screenshots, or recordings.
Websites inside previews
Pages loaded inside the responsive workspace can make their normal network requests. Those requests go to the websites and services the page already uses and remain governed by their own privacy policies.
Other third-party services
The extension and public marketing website contain no analytics, advertising, session-recording, or hosted AI SDK. The fix-prompt feature formats text locally and copies it only when you press the copy button.
Open-source verification
You do not have to take these statements on trust. Review the extension's implementation, permissions, and storage behavior in the public source repository.
