PRIVACY POLICY - IMAGE SIZE INFO EXTENSION
Last Updated: August 5, 2026
1. INTRODUCTION
Image Size Info ("the Extension") is dedicated to protecting user privacy. This Privacy Policy outlines how the Extension handles information, data processing, and why specific browser permissions are required for its operation.
The Extension is designed to allow users to view image and video dimensions, file sizes, and metadata directly via the context menu on any web page.
2. DATA COLLECTION AND USE
- Personal Information: The Extension DOES NOT collect, store, track, sell, or transmit any personal identification data, browsing history, or personal web traffic.
- Image & Web Page Data: All image size inspection, dimension calculation, and metadata analysis occur locally in the user's browser session. No content from web pages visited by the user is collected or sent to any external servers.
3. DETAILED PERMISSION JUSTIFICATIONS
The Extension requests only the minimum necessary permissions required to provide its core functionality and premium account management:
a) contextMenus
- Purpose: Adds the "View Info" item to the browser's right-click context menu when right-clicking on images or video elements.
- Justification: Enables users to trigger the image metadata inspection feature directly from any web page.
b) scripting
- Purpose: Allows dynamic injection of the content script (`includes/content.js`) onto the active web page when required.
- Justification: Ensures the information overlay card can be rendered reliably, even on pages loaded prior to extension installation or update.
c) storage
- Purpose: Accesses local and synchronized browser storage (`chrome.storage.local` and `chrome.storage.sync`).
- Justification: Saves user preferences (e.g., custom dimension display formats, info box width, UI field toggles), trial usage counts, and premium login/subscription state across browser sessions.
d) cookies
- Purpose: Reads and sets a specific domain cookie (`myexthub_trial_start`) on `https://myexthub.com`.
- Justification: Used solely for free trial anti-abuse protection (preventing trial resets via extension reinstallations). No third-party tracking cookies or personal user cookies are accessed.
e) host_permissions: <all_urls>
- Purpose: Grants permission to inspect image and video elements on websites visited by the user.
- Justification: The core purpose of the extension is to inspect and display metadata for images hosted across any domain on the web. Network access is strictly used to fetch image headers (HEAD/GET requests for image file size and dimensions) locally in the browser.
f) host_permissions: https://myexthub.com/*
- Purpose: Allows communication with the MyExtHub account backend.
- Justification: Enables premium account authentication, subscription status synchronization, and trial state verification when a user logs in to MyExtHub.
4. THIRD-PARTY SERVICES AND REMOTE COMMUNICATIONS
The Extension communicates only with `https://myexthub.com` for the sole purpose of verifying subscription status and account authentication for premium users. No user data is sold, rented, or shared with third parties.
5. SECURITY
We prioritize user data safety. All stored settings and trial counts remain strictly within the browser's native storage sandbox (`chrome.storage`). All remote communications with MyExtHub are encrypted via secure HTTPS endpoints.
6. CHANGES TO THIS PRIVACY POLICY
We may update this Privacy Policy periodically. Any changes will be updated in this file.
