Chrome Extension

Privacy Policy

Simple PWA Builder for Microsoft Store — last updated June 24, 2026

Plain-language summary This extension does not collect, store, transmit, or sell any personal data. All processing happens locally in your browser. There is no backend server, no analytics, and no third-party tracking of any kind.

What the extension accesses

What	Why	Leaves your device?
Active tab — web app manifest, icon, page title, URL	Pre-fill the build form. Only accessed when you click the extension.	No
`chrome.storage.local` — fill history (publisher / identity values you typed)	Convenience: your recently entered values appear as autocomplete suggestions.	No
`chrome.storage.session` — detected site info	Temporary handoff from the popup to the builder page (cleared when the browser session ends).	No
Downloads — `.msix` / `.zip` files	Save the package(s) you generate to your computer.	No

What the extension does NOT do

Send any data to the author or any third party.
Load or execute remote code (all logic is bundled in the extension).
Collect browsing history, cookies, or credentials.
Use analytics, crash reporting, or telemetry services.
Make network requests itself — the “Support the author” button simply opens an external page in a new tab when you click it.

Permissions used and why

Permission	Reason
`activeTab`	Read the current tab's manifest and icon only when you invoke the extension. No persistent or background tab access.
`scripting`	Execute a small reader in the active page to fetch the manifest and best icon with the page's own origin credentials (so icon URLs on CDNs resolve correctly).
`storage`	Fill history (`chrome.storage.local`) and popup→builder handoff (`chrome.storage.session`), both local-only.
`downloads`	Save the generated `.msix` and `.zip` packages you build.

No host permissions are requested. The extension only accesses the tab you explicitly act on.

Data retention & deletion

Fill history is stored in chrome.storage.local on your device only. To delete it, remove the extension from Chrome (chrome://extensions → Remove). Session data is automatically cleared when you close the browser.

Third-party services

The extension itself makes no calls to any third-party service. If you click the donation link, your browser navigates to an external donation platform (Ko-fi). That platform's own privacy policy applies from that point on.

Children

This extension is a developer tool and is not directed at children.
