Privacy policy

In short

LinkUnzip has no accounts, no analytics, no ads and no servers of its own. It does not collect, sell or share any data about you. It connects only to the server of the link you chose, and the files you extract stay on your disk.

What happens when you extract a zip

You choose a link (right-click Extract with LinkUnzip, the toolbar popup, or a caught .zip download).
The extension passes that link to the LinkUnzip helper on your own PC through the browser's native messaging. Nothing goes to the LinkUnzip project or anyone else.
The helper connects to the server in that link and downloads only the parts of the zip it needs. If that server redirects the download to another address (download mirrors and CDNs often do), the helper follows it, as a browser would.
The helper writes the extracted files into the folder you chose. The zip itself is never saved.

Along with the link, the extension may pass the address of the page where you found it and your browser's name and version (the same Referer and User-Agent your browser sends for a normal download), so that servers which check them still work.

Some downloads only work when you are logged in to the site. For those, LinkUnzip can use your browser's cookies for that one site, only if you allowed it:

LinkUnzip asks the first time a download needs your login on a site (for example Use my login on example.com). The browser shows its own permission prompt and remembers your answer for that site.
In Settings you can instead allow Use my login on every site. It is off unless you turn it on.
With that permission, the extension reads the cookies for the link's site only, at the moment you start, and passes them to the helper on your PC. The helper sends them only to that site, and drops them if the download is redirected to a different site.
Cookies are never stored by LinkUnzip, never written to disk by it, and never sent anywhere else.

Public links need no permission at all: without it, no cookies are read.

What is stored, and where

Settings (base folder, number of connections, login options, Catch .zip downloads): in the browser's extension storage on your PC.
The state of current jobs (link, folder, progress, file names) so the popup can show it: in the browser's session storage, cleared when the browser closes.
Extracted files: in the folder you chose. They are yours; LinkUnzip never uploads them.
Resume information: while a job is unfinished, the helper keeps a small progress file (.linkunzip-resume.jsonl) in the destination folder so it can skip finished files next time. It is deleted when the job finishes.
The helper keeps no logs and no history.

Other things the extension can see

ZIP links on the current page: when you open the toolbar popup, the extension looks at the page you are on for links ending in .zip and lists them in the popup. Nothing is kept or sent.
Downloads: if you turn on Catch .zip downloads (off by default), the extension notices when the browser starts downloading a .zip, cancels that download and offers it to LinkUnzip instead. It does not look at other downloads.
Copy details: after an error, this button copies the versions, Windows version, error code, HTTP status, the host name and the technical error text to your clipboard. Web addresses are cut down to their host name, so the full link is never included; for a disk error, the text can name the file or folder on your PC that failed. It is sent nowhere; you decide whether to paste it into a bug report.

The data the store listings name

The Chrome Web Store and Edge Add-ons ask every extension which kinds of user data it handles, even when the data never leaves the user's PC. By their definitions LinkUnzip handles three kinds, all of them only on your PC:

Authentication information: a site's cookies, only after you allowed that site (see Your browser login). The extension passes them to the helper, which sends them only to that site.
Web history: the link you chose and the address of the page it was on, passed to the helper so it can download the zip.
Website content: the .zip links on the page you are on, read when you open the toolbar popup so it can list them.

Where any of it is kept is listed under What is stored, and where. None of it reaches the LinkUnzip project or anyone else.

Connections LinkUnzip makes

The helper connects to the servers of the links you choose (and the addresses they redirect to). Nothing else.
When you click Download on the extension's setup page, your browser downloads the helper's installer from the project's GitHub releases page (github.com/CincaAlex/LinkUnzip/releases), under GitHub's own privacy policy.
No analytics, crash reporting, update checks or remote code. Updates to the extension come through the browser's extension store.

LinkUnzip does not sell, rent, share or transfer any data, does not use data for advertising or credit decisions, and has no servers that could receive it.

Removing everything

Remove the extension: chrome://extensions (or edge://extensions), LinkUnzip, Remove. This deletes its settings, its job state and the site permissions you granted. (To withdraw only the login permissions, turn off Use my login on every site in Settings, or remove sites under the extension's Details page.)
Remove the helper: Windows Settings > Apps > Installed apps, LinkUnzip, Uninstall. This deletes the program and its browser registrations. If you installed it from the command line with linkunzip host install, run linkunzip host uninstall instead.
Extracted files stay where you put them until you delete them.

This website

linkunzip.app sets no cookies, runs no analytics and loads nothing from other servers. If you switch between the light and dark theme, your choice is kept in your own browser (local storage) and never sent anywhere. The site is served by Cloudflare, which handles the connection to your browser.

Changes

If this policy changes, the new version is published here with a new date, and the change is visible in the project's public history. A change that would collect or share data in a new way would be announced in the release notes first.
