Lumivor ("we," "our," or "us") values your privacy. This Privacy Policy explains how DeviceLab – Responsive Testing & Capture Devices in 2D/3D (the "Extension") and our website handle user information.
By using DeviceLab, you agree to the practices described in this Privacy Policy.
We respect your privacy. DeviceLab is designed with privacy first principles and does not collect, store, or transmit any personal data to our servers or third parties.
No Account Required
You do not need to sign up or provide personal information to use DeviceLab.
No Tracking
We do not track browsing activity, visited websites, or user behavior.
No Analytics
We do not use Google Analytics or any other third-party analytics tools.
The only data that exists during your usage is handled locally within your browser.
Device Simulation
DeviceLab simulates different devices (mobile, tablet, laptop, TV, smartwatch) directly within your browser. This functionality happens locally without sending data anywhere.
Screenshots & Recordings
When you take a screenshot or record a session, the data is temporarily processed locally on your device. You may choose to download these files. If you do not save them, they are automatically discarded after your session.
Local Storage
The extension may save your preferences (e.g., last selected device, orientation, UI settings) in your browser's local storage to improve your experience. This information never leaves your device.
DeviceLab requires certain Chrome Extension permissions to function, including:
to enable screenshots and recordings
to simulate devices on the current site
to save local user preferences
to adjust headers like User-Agent for device simulation
These permissions are used solely for functionality and never for tracking or data collection.
DeviceLab does not use any third-party services for analytics, data storage, or advertising. All functionality is self-contained and processed locally using standard Chrome APIs, React, and Three.js libraries.
Since no personal or browsing data is collected or transmitted, the risk of unauthorized access is minimal. Screenshots and recordings remain entirely under your control and are never uploaded by us.
DeviceLab does not knowingly collect information from children under 13. Since no data collection occurs, the extension is safe for all users.
As DeviceLab does not collect any personal data, there is no data to access, modify, or delete. All generated content (screenshots, recordings) remains under your control.
We may update this Privacy Policy from time to time. Changes will be posted on our website with an updated effective date. We encourage you to review it periodically.
