1. Overview
Closely Image Zoom ("the Extension") is a browser extension designed to enable image zooming and panning
functionality on websites. This Privacy Policy explains how we collect, use, and protect user information.
Key Principle: We do not collect, store, or transmit personal data. The Extension operates
entirely locally within your browser.
2. What Data We Collect
The Extension collects minimal data, all stored locally on your device:
A. Preference Settings
- Global enable/disable toggle state
- Per-site enable/disable settings (e.g., "disabled_instagram.com")
- These are stored in browser.storage.sync for consistent settings across devices logged into the same browser account
B. Active Tab Information
- Website hostname (e.g., "instagram.com") to populate the "Enable on this site" label in the popup
- This information is used only to display which site you are currently viewing
- It is never logged, transmitted, or stored on external servers
C. Image Data
- The Extension reads image elements in the webpage's DOM to apply zoom and pan effects
- Image data remains in your browser's memory during use
- No image data is stored, cached, or transmitted
3. How We Use Data
All collected data is used exclusively for:
- Injecting zoom and pan functionality into image elements
- Remembering your enable/disable preferences per-site
- Displaying the correct site name in the extension popup
- Restoring your settings across browser sessions
Data is not used for:
- Analytics or usage tracking
- Behavioral profiling
- Advertising or marketing
- Selling, renting, or sharing with third parties
- Any purpose unrelated to the Extension's core function
4. Data Storage and Retention
All data is stored locally in your browser:
- Settings are stored using Chrome's storage.sync API (local to your device)
- No data is transmitted to external servers or databases
- Settings persist only while the Extension is installed
- Uninstalling the Extension automatically removes all associated data
You can manually clear all Extension data at any time via browser settings:
Chrome: Settings > Privacy and Security > Clear browsing data > Cookies and other site data
5. Third-Party Services
The Extension does not use any third-party services:
- No analytics platforms (Google Analytics, Mixpanel, etc.)
- No crash reporting services
- No external APIs or remote code loading
- No CDNs for assets or data
The Extension is entirely self-contained and makes no external network requests.
6. Permissions Explained
The Extension requests the following permissions, necessary for its core functionality:
activeTab
Detects the current website hostname to enable per-site toggles in the popup. The hostname is read
only when you open the popup and is not logged or transmitted.
host_permissions (<all_urls>)
Required to inject zoom and pan logic into image elements on any website. No user data is collected;
the permission only enables the zoom feature to work everywhere.
storage
Used to store user preferences (enabled/disabled state) locally in your browser. Data never leaves
your device.
7. User Rights and Control
You have full control over the Extension:
- Enable or disable globally for all websites
- Enable or disable on individual sites
- Clear all stored settings at any time
- Uninstall the Extension to remove all associated data
- No user account or login is required
8. Security
Although the Extension does not transmit data, we implement security best practices:
- All code is bundled locally within the Extension package
- No external scripts or dynamically loaded code
- No transmission of data over networks
- Your zoom and pan interactions remain entirely on your device
9. Children's Privacy
The Extension is not directed at children under 13. We do not knowingly collect data from children.
If you believe a child has used the Extension, no personal data has been collected, and no action is required.
10. Changes to This Privacy Policy
