Privacy Policy

PWA & Installability Inspector · Effective 7 July 2026

Short version: This extension collects nothing. It has no analytics, no telemetry, and no servers. Everything it reads about a page is processed locally in your browser and never leaves your device.

What the extension does

PWA & Installability Inspector analyzes the website you are viewing to report how well it meets Progressive Web App (PWA) standards — its Web App Manifest, service worker, icons, offline readiness, and use of advanced capability (“Fugu”) APIs — and offers recommendations and generators (manifest export, icon set, code snippets).

Data we collect

None. We do not collect, transmit, sell, or share any personal or usage data. There is no tracking, no analytics, and no account. The developer never receives any information about you or the sites you inspect.

What the extension accesses (locally only)

To produce a report, and only for the tab you are actively inspecting, the extension reads:

The page’s Web App Manifest and its icons.
The page’s service worker registration state.
The page’s scripts, to detect which capability APIs it uses.
Relevant <meta> / <link> tags.

All of this is analyzed in memory in your browser to build the report. It is not sent anywhere.

Local storage

Audit results (“snapshots”) are stored locally on your device using chrome.storage.local so you can review and compare them. This data stays on your device, is never transmitted, and is removed if you uninstall the extension.

Network activity

The only network requests the extension makes are to the inspected site’s own resources — its manifest, icons, and scripts — fetched from the page’s context to analyze them. No data is sent to the developer or any third party.

Permissions

activeTab / scripting — to read the current page you choose to inspect.
storage — to save audit snapshots locally on your device.
tabs — so the full-report page can find the inspected tab to re-run checks.
Host access (requested on demand, per site) — granted by you when you run the report on a specific site, used only to read that site’s PWA-related resources.

Third parties

No third-party services, SDKs, or analytics are used.
