LupaLayer Privacy Policy
Last updated: March 14, 2026
Overview
LupaLayer is a Chrome browser extension for pixel-perfect front-end development, developed by NexSolvo LLC. This privacy policy explains how the extension handles your data.
Data Collection
LupaLayer does not collect, transmit, or store any personal data. The extension does not use analytics, tracking, cookies, or any form of data collection.
Data Storage
All extension data is stored locally on your device using Chrome's chrome.storage.local API. This includes:
- Overlay image URLs or uploaded image data
- Measurement data (rulers, lines, guides)
- UI preferences (toolbar position, collapsed sections, selected color)
- Figma personal access token (if provided)
This data never leaves your device except as described below.
Network Requests
LupaLayer makes network requests only in the following case:
- Figma API: When you explicitly click the "Fetch" or "Re-fetch" button to load a design from Figma. The request is sent directly to Figma's API using your personal access token. No data is routed through any third-party server.
No other network requests are made. The extension does not communicate with any servers owned or operated by the developer.
Figma Access Token
If you choose to use the Figma integration, your Figma personal access token is:
- Stored locally in
chrome.storage.localon your device - Sent only to Figma's official API (
api.figma.com) when you request a design fetch - Never transmitted to any other server or third party
- Deletable at any time by clearing the token field in Settings
