## Description

**KD Tracking Connector for OpenPanel** is a lightweight, standalone plugin that
brings professional web analytics to your WordPress site without touching a single
line of theme code. Everything is set up from one place: **Settings  OpenPanel**.

Under the hood, the plugin connects to [OpenPanel](https://openpanel.dev), an open-
source, privacy-friendly alternative to Google Analytics. Whether you use the official
OpenPanel Cloud or your own self-hosted instance, the plugin handles the integration
for you.

#### What you get

 * **Zero-code setup** – enter a Client ID, flip a switch, done. No editing of `
   functions.php` or theme files required.
 * **Works with any theme** – runs completely independent of your active theme.
 * **One settings screen** – every option lives under **Settings  OpenPanel**, nothing
   scattered across menus.
 * **Self-hosted or cloud, your choice** – point it at your own OpenPanel server,
   or leave the API URL empty to use the official cloud.
 * **Local script delivery** – the tracking script is served straight from the plugin
   folder, avoiding an extra external request on page load.
 * **Fine-grained tracking control** – toggle page views, outgoing-link tracking
   and `data-track` attribute tracking independently.
 * **Optional Session Replay** – record mouse movements, scroll behaviour and clicks,
   with automatic input masking to protect sensitive form data.
 * **Built-in privacy safeguards** – honour Do Not Track, exclude logged-in users,
   and automatically disable tracking on local/staging sites running `WP_DEBUG`.
 * **Translation-ready** – ships with English and German (informal “Du” and formal“
   Sie”) out of the box; more languages are welcome via [translate.wordpress.org](https://translate.wordpress.org/projects/wp-plugins/kd-tracking-connector-openpanel/).

#### About OpenPanel

OpenPanel is the open-source (MIT-licensed), self-hostable analytics engine that
does the actual tracking – real-time stats, custom events, session replay, and cookie-
free basic page-view tracking. No data is ever sent to Google. Learn more at [openpanel.dev](https://openpanel.dev).

#### Settings

All options are available under **Settings  OpenPanel**:

 * **Enable OpenPanel** – Enable or disable the tracking script globally. (Default:
   off)
 * **Client ID** – The Client ID of your OpenPanel application.
 * **API URL (Self-Hosted)** – Your self-hosted API endpoint, e.g. `https://analytics.
   example.com/api`. Leave empty to use the official cloud.
 * **Serve op1.js locally** – Load the tracking script from the plugin folder instead
   of an external CDN. (Default: on)
 * **Track page views** – Automatically track every page view. (Default: on)
 * **Track outgoing links** – Track clicks on external links. (Default: on)
 * **Track data attributes** – Track events via `data-track` HTML attributes. (Default:
   on)
 * **Enable Session Replay** – Record mouse movements, scroll behaviour and clicks.(
   Default: off)
 * **Mask form fields** – Prevent plain-text capture of input fields in session 
   replays. (Default: on)
 * **Skip logged-in users** – Exclude admins and logged-in users from tracking. (
   Default: on)
 * **Respect Do Not Track** – Honour the DNT browser signal. (Default: on)
 * **Disable on WP_DEBUG** – No tracking on local or staging environments when `
   WP_DEBUG` is active. (Default: on)

### Third-Party Services

This plugin integrates with **OpenPanel Analytics** ([openpanel.dev](https://openpanel.dev)),
an open-source web analytics platform.

**Cloud service** (API URL left empty): Visitor data including page views, custom
events and optional session recordings is transmitted to servers operated by OpenPanel
at `https://openpanel.dev`.

**Self-hosted**: All data goes exclusively to your own server. Nothing is sent to`
openpanel.dev`.

#### Bundled JavaScript Files

    ```
    assets/js/op1.js and `assets/js/op1-replay.js` are local copies of the official OpenPanel tracking scripts in minified form. The non-minified source code is available at [github.com/openpanel-dev/openpanel](https://github.com/openpanel-dev/openpanel).
    ```

## Installation

 1. Install the plugin via **Plugins  Add New Plugin** and search for “KD Tracking 
    Connector for OpenPanel” – or upload the ZIP manually.
 2. Activate the plugin via **Plugins  Installed Plugins**.
 3. Go to **Settings  OpenPanel**.
 4. Enter your **Client ID** (and optionally your self-hosted API URL).
 5. Check **Enable OpenPanel** and save.

#### Requirements

 * WordPress 6.0 or later
 * PHP 8.0 or later
 * An OpenPanel account – [cloud](https://openpanel.dev) or self-hosted

#### Keeping op1.js Up to Date

    ```
    op1.js and `op1-replay.js` are bundled with the plugin. To update them manually when a new OpenPanel version is released:
    ```

**Linux / macOS:**

    ```
    curl -o assets/js/op1.js https://openpanel.dev/op1.js
    curl -o assets/js/op1-replay.js https://openpanel.dev/op1-replay.js
    ```

**Windows (PowerShell):**

    ```
    Invoke-WebRequest -Uri "https://openpanel.dev/op1.js" -OutFile "assets/js/op1.js"
    Invoke-WebRequest -Uri "https://openpanel.dev/op1-replay.js" -OutFile "assets/js/op1-replay.js"
    ```

## FAQ

### What does this plugin actually do?

It adds an admin screen (**Settings  OpenPanel**) where you configure privacy-friendly
analytics tracking for your site – no manual code editing. The plugin injects a 
small init script and loads the OpenPanel tracker, based purely on the options you
set.

### Do I need an OpenPanel account?

Yes. You need a Client ID from either the [OpenPanel Cloud](https://openpanel.dev)(
free to sign up) or your own self-hosted OpenPanel instance.

### Does the plugin support the OpenPanel Cloud service?

Yes – simply leave the API URL field empty. The plugin will connect to `https://
openpanel.dev` automatically.

### Is this plugin GDPR-compliant?

OpenPanel is designed with privacy in mind. Basic page-view tracking works without
cookies. You can additionally enable Do Not Track support and exclude logged-in 
users. Consult your legal advisor for your specific situation and jurisdiction.

### What happens when WP_DEBUG = true?

When “Disable on WP_DEBUG” is active (default), no tracking script is rendered. 
This prevents accidental data collection on development or staging environments.

### Are logged-in WordPress users tracked?

Not by default. The “Skip logged-in users” option is enabled and excludes all authenticated
users before the script is rendered.

### Where is the tracking script injected?

The initialisation script is inserted at priority 5 in `<head>` (before most other
scripts). `op1.js` is enqueued with `defer` so it does not block page rendering.

### How do I track custom events?

**Via JavaScript:**

    ```
    window.op('track', 'my_event', { foo: 'bar' });
    ```

**Via HTML attribute** (when “Track data attributes” is active):

    ```
    <button data-track="ticket_purchase">Buy ticket</button>
    ```

### How do I protect specific elements from Session Replay?

Use `data-openpanel-replay-mask` to mask text content or `data-openpanel-replay-
block` to replace an element entirely in the recording.

### Can I configure the plugin via WP-CLI?

Yes. Activate or deactivate it with `wp plugin activate|deactivate kd-tracking-connector-
openpanel`. All settings are regular WordPress options with the `opsh_` prefix and
can be read or set with `wp option get|update`, e.g. `wp option update opsh_enabled
1` or `wp option update opsh_client_id "abc123"`. See the plugin’s README.md for
the full list of options.

### How do I translate the plugin?

The recommended way is to contribute a translation directly on [translate.wordpress.org](https://translate.wordpress.org/projects/wp-plugins/kd-tracking-connector-openpanel/)–
once a translation is approved there, WordPress automatically downloads and uses
it as an official language pack for your site’s language.

Alternatively, if you’re not installing from WordPress.org (e.g. a manually uploaded
ZIP), you can use `languages/kd-tracking-connector-openpanel.pot` as the translation
template. Create a `.po` file for your locale (e.g. `kd-tracking-connector-openpanel-
fr_FR.po`), translate it, and compile it to a `.mo` file with `msgfmt` or Poedit.
Bundled translation files are only used as a fallback until an official language
pack is available.
