Feedback

Help improve Lenxel Core by optionally sharing deactivation feedback. This feature is disabled by default and requires opt-in via LenxelWP → Privacy & Feedback. See the “External Services” section below for complete details on what data is collected and how it’s used.

Plugin prerequisites

1. Ensure that the WooCommerce plugin is installed and activated on your WordPress website.
2. Install the Tutor plugin to manage curriculum, quizzes, and curriculum assignments.
3. Install the Lenxel theme template to complete the setup.

External services

This plugin relies on several external services to provide its functionality. Below is a complete list of all external services used, including comprehensive details about what data is sent, when it’s sent, code locations, and links to each service’s Terms of Service and Privacy Policy.

IMPORTANT DISTINCTION: This section documents actual external API services that receive data during plugin operation. URLs that appear in third-party vendor library code (like documentation links, comments, or unused features) are addressed separately at the end of this section under “Third-Party Vendor Library Code.”

1. Lenxel AI API

Service URL: https://api.lenxel.ai (production) and https://devapi.lenxel.ai (development)
Service Provider: Lenxel (Ogun Labs)

Purpose: Generates AI-powered course content including course modules, lessons, quizzes, and questions automatically.

What Data is Sent: When users click the “Generate with AI” button or request AI course generation, the following data is transmitted:
– Course title and description
– Supporting files and course prompts provided by the user
– API Key (obtained from the Lenxel User Portal – see below) for authentication and credit tracking
– WordPress site URL (for API key validation)

When Data is Sent: Only when users explicitly request AI course generation through the plugin interface, or when API key validation is performed.

API Endpoints Used:
– https://api.lenxel.ai/wp/sites/status/verify – API key validation (optional, informational only)
– https://api.lenxel.ai/ – Course generation endpoints
– All requests are sent via wp_remote_post() and wp_remote_get()

Code Location: lenxel-core.php (line 502 and related functions) – Uses wp_remote_post() to send course data to Lenxel API endpoints

IMPORTANT: API Key Validation
When users optionally enter an API key, the plugin may send a validation request to https://api.lenxel.ai/wp/sites/status/verify to verify the key is valid. This validation is informational only and does NOT gate or restrict any plugin features. All functionality is fully available regardless of API key validation status.

Note: API keys and AI credits are managed through the Lenxel User Portal (https://portal.lenxel.ai) – see section 5 below for details.

This feature is disabled by default and requires explicit opt-in consent. To enable deactivation feedback:
1. Go to WordPress Admin → LenxelWP → Privacy & Feedback tab
2. Check the “Help improve Lenxel Core by sharing why you deactivate the plugin” checkbox
3. Click “Save Settings”

Without opting in, NO data is collected when you deactivate the plugin.

What Data is Sent (Only if Opted-In and Only if User Chooses to Provide Feedback):
Even after opting in, providing feedback is still optional. When the deactivation modal appears, users can:
– Click “Skip & Deactivate” to bypass feedback submission entirely
– Close the modal without submitting
– OR submit feedback by completing the form

If feedback is submitted via wp_remote_post(), the following data is sent to the Google Cloud Run endpoint:
– Deactivation reason selected from predefined choices (e.g., “I no longer need the plugin”, “The plugin broke my website”, “I found a better plugin”, etc.)
– Optional additional comment or alternative plugin name (if user chooses to provide it)
– Site administrator’s email address (only if user explicitly checks “Include my email” checkbox)
– WordPress site URL (home_url)
– Date and time of deactivation

When Data is Sent:
1. User must first opt-in via LenxelWP → Privacy & Feedback (disabled by default)
2. Then, when a site administrator clicks the “Deactivate” button for this plugin in the WordPress plugins page, a feedback modal appears
3. User can still choose to skip or submit feedback
4. Data is only transmitted if the user completes the form and clicks “Submit & Deactivate”

Code Location: lenxel-core.php (lines 640-690) – Deactivation handler with opt-in check and wp_remote_post() to Google Cloud Run endpoint (line 684)

How to Disable:
To stop seeing the feedback modal entirely:
1. Go to LenxelWP → Privacy & Feedback
2. Uncheck the deactivation feedback option
3. Click “Save Settings”

You can also skip the modal on a per-deactivation basis by clicking “Skip & Deactivate” or closing the modal.

Important Notes:
– This is completely opt-in and disabled by default – you must explicitly enable it in plugin settings
– Even after enabling, providing feedback is optional on each deactivation
– The feedback modal only appears to site administrators with plugin management capabilities
– No data is transmitted if the user skips or closes the feedback form
– Email address is only sent if the user keeps the “Include my email” checkbox checked

Third-Party Vendor Library Code (Not External Services)

IMPORTANT: The following URLs appear in third-party vendor library code included with this plugin. These are NOT external API services called by this plugin – they are simply documentation URLs, comments, or dead code within vendor libraries. NO data is transmitted to these URLs during plugin operation.

1. Vzaar API URL in Owl Carousel Library
Code Location: elementor/assets/libs/owl-carousel/owl.carousel.js (line 2388)
URL Found: url: '//vzaar.com/api/videos/' + video.id + '.json'
Library: Owl Carousel 2.x (MIT Licensed)
Status: This is a hardcoded URL within the Owl Carousel JavaScript library’s video support feature. The Vzaar video platform integration is NOT used or called by this plugin – it’s simply part of the complete Owl Carousel library code that includes support for various video platforms (YouTube, Vimeo, Vzaar, etc.). The URL appears in a JavaScript object but the Vzaar feature is never invoked by this plugin.
Data Sent: NONE – This URL is never contacted during plugin operation.

2. React Router Documentation URLs

– And other similar upgrade guide URLs

Library: React Router (MIT Licensed)
Status: These URLs are documentation/warning links embedded in the React Router library code that appear in built JavaScript bundles. They are used in console warnings to guide developers during React Router version upgrades. They are NOT API endpoints and do NOT receive any data during plugin operation. These are purely informational links that may appear in browser developer console warnings.
Data Sent: NONE – These are documentation reference links only.

3. Redux Framework Vendor Code
Code Location: redux/redux-framework/ directory
Library: Redux Framework 4.x (MIT Licensed)
Status: The Redux Framework is a complete third-party library that includes various extensions and features. Some features (like Google Maps fields and Custom Fonts API) may reference external services, which are documented separately in sections 2 and 6 above where applicable.

Important Notes:
– All data transmissions to Lenxel services (AI API, User Portal) are sent over secure HTTPS connections.
