Fxvnpro Script Manager

FXVNPro Script Manager is a lightweight, secure userscript runner for Chrome.
It lets you create, edit, enable/disable, and execute custom JavaScript on the
websites you choose. Import/export scripts as JSON, manage per‑site rules,
and run a script on the active tab with one click.

Key features
• Per‑script enable/disable
• Domain matching (regex or host list)
• “Run Now” on current tab (user gesture)
• Import/Export scripts (JSON)
• Local storage only — no cloud backend

Single Purpose
--------------
This extension’s single purpose is to let users run their own scripts on
websites they explicitly choose. It does not collect personal data or modify
pages beyond the user’s configured rules.

Permission Justification
------------------------
• storage — to save users’ scripts and settings locally in the browser.
• scripting — to inject and execute the user’s script code.
• activeTab — to run a script in the currently active tab when the user clicks
“Run Now”. Access is temporary and requires an explicit user gesture.
• optional_host_permissions (http/https) — requested at runtime only when the
user enables a script for specific domains. This allows automatic execution
on those sites without requesting broad access.

Data Usage
----------
All scripts and settings are stored locally via Chrome storage. The extension
does not collect or transmit personal data, page content, or browsing history
to external servers. If the optional telemetry setting is enabled by the user,
only anonymous, minimal events (e.g., “popup_open”, extension version, and a
random installation ID) are sent to the user‑configured endpoint. No URLs,
page content, or personal identifiers are included. Telemetry is off by default
and can be turned off at any time.

Privacy
-------
• No personal data collected.
• No reading or storing page content beyond the user’s scripts’ execution.
• No third‑party sharing.
• Optional telemetry is off by default and fully user‑controlled.

How it works (reviewer summary)
-------------------------------
• The extension does not request host permissions by default.
• “Run Now” uses activeTab and only runs after an explicit user action.
• When a user enables a script, the extension requests the minimum origin
permissions needed (via optional_host_permissions). Auto‑inject is performed
only for origins that were granted by the user.
• All functionality is limited to the user‑configured sites and scripts.
