Privacy Policy — Image Downloader Pro

Last updated: August 16, 2026

Summary: Image Downloader Pro does not collect, store, or transmit any personal data to the developer or any third party. All image scanning, format conversion, and PDF generation run entirely locally in your browser — there is no backend server behind this extension.

What this extension does NOT do

Does not collect your browsing history, keystrokes, passwords, or any personal information.
Has no backend server — your data (images, page URLs, usage activity...) is never sent anywhere controlled by the developer.
Does not use analytics or tracking tools, does not show ads, and does not sell or share data with third parties.
Does not require sign-in or account creation.

Permissions requested and why

Permission	What it's used for
`activeTab` / `scripting`	Scans `<img>` tags, `<picture>` elements, CSS background images, and lazy-loaded images on the page you have open to list downloadable images. Only runs when you actively open the side panel — no background execution.
`<all_urls>` (host permissions)	Lets the extension scan images on any website you're viewing (since you may want to download images from any site), and lets it send the correct Referer header for sites that block hotlinking (see `declarativeNetRequestWithHostAccess` below).
`downloads`	Saves the images/ZIP/PDF you select to your Downloads folder — only happens when you click "Download".
`storage`	Stores exactly one preference: your light/dark theme choice, saved locally on your device (`chrome.storage.local`) — never synced to any server, never leaves your machine.
`tabs`	Reads the URL of the currently open tab to: (1) know which page is being scanned, (2) automatically re-scan when you switch tabs. Does not read the history of other tabs.
`declarativeNetRequestWithHostAccess`	Some sites (particularly manga/comic sites) block image downloads without a correct `Referer` header. The extension uses this permission to attach the `Referer` header only to requests the extension itself makes (the rule is scoped to `initiatorDomains` and does not affect your regular browsing or any other extension/site).
`sidePanel`	Displays the extension's UI as a Chrome side panel instead of a popup.

Images and files you download

When you download an image, the extension fetches it directly from the site that hosts it (that site's own CDN/server) — never through any server operated by the developer.
Format conversion (PNG/JPG/WEBP), resizing, and PDF generation are all processed using <canvas> right inside your browser, using two open-source libraries that run locally (JSZip, jsPDF) — images are never uploaded to any server for processing.
Downloaded files are saved directly to your Downloads folder (or a subfolder you name) on your machine; the extension keeps no other copy.

Children's privacy

This extension is not directed at, and does not knowingly collect information from, children under 13.
