What FixZtream does

FixZtream is a browser extension that runs a fixed set of Windows troubleshooting tasks through a companion helper program installed on your PC — for example System File Checker, DISM, temp-file cleanup, a Microsoft Defender quick scan, DNS and network resets, print-spooler, audio and camera fixes, battery and disk health reports, Windows Update repairs and Chinese language installs. It can also open built-in Windows tools such as Device Manager. It can also clear a website's stored data (cache, cookies and site storage) in your browser when you ask it to.

Site data

When you open FixZtream, it looks at the tab you are on to show the Clear site data card. Chrome only allows this for the tab where you clicked the FixZtream icon. FixZtream reads:

• the site's address (for example, https://mail.google.com), so it knows which site to clear;
• how much storage the site uses, as totals by type (for example, cache storage 37 MB), using the browser's standard storage estimate.

It does not read the page's content, your cookie values, what the site has stored, or your browsing history. Nothing is cleared until you press the button, and clearing happens inside your browser. The site's address and the amount cleared are written to the activity log on your device.

Information stored on your device

To show you an activity log, the extension keeps the following in your browser's local extension storage:

• A record of each task you run: its name, start and end time, result, and the text output of the task.
• Your chosen language components (for example, Handwriting or OCR).
• The most recent status of the Windows Update and BITS services, the size of the update cache folder, free space on the system drive, time since the last restart, and whether a restart is pending.
• For site-data clears: the site's address, which data types were cleared, and how much space was freed.
• Your chosen site-data options (for example, whether to include cookies).

The companion helper also appends a one-line summary of each task to %ProgramData%\FixZtream\activity.log on your computer (or %LOCALAPPDATA%\FixZtream for tasks that run without admin rights). The battery report is saved to %LOCALAPPDATA%\FixZtream\reports. Task output may include your Windows user name, computer name, IP addresses, disk and device names.

This information never leaves your device. You can clear the extension's log at any time with the Clear button, and remove the file log by running the helper's uninstaller with -RemoveLogs.

What we do not do

• We do not collect, transmit, sell or share any personal or usage data.
• We do not use analytics, cookies, advertising or third-party services.
• The extension does not read your browsing history or the contents of web pages, and it only looks at the tab you opened it on, as described under Site data.

Network activity

The extension itself makes no network requests. Some tasks make Windows contact Microsoft, exactly as if you ran them yourself: installing a language and DISM repairs download from Windows Update (or your organisation's update server), and the Defender scan first updates its definitions. Those downloads are governed by Microsoft's privacy terms. The Download helper link opens the helper's GitHub release page in your browser.

Permissions

• Native messaging — to send the selected task or Windows tool name to the helper on your PC and receive its output.
• Storage — to keep the activity log and your settings on your device.
• Notifications — to tell you when a task finishes.
• Side panel — to let you keep the tool open beside your pages.
• Browsing data — to clear a site's cache, cookies and storage (or all sites') when you press Clear site data.
• Active tab and scripting — to read the current site's address and storage totals after you click the FixZtream icon on that tab.

Changes

If this policy changes, the updated version will be posted on this page with a new effective date.
