About this plugin
Stedica LMS turns a WordPress site into a full training platform, with no external
service required.
For learners
Course catalog and self-enrolment, a course player with resume, progress tracking and
drip-released lessons, eight quiz types, certificates, leaderboards and achievements.
For instructors
A drag-and-drop course builder (lessons and topics: text, video, audio, document, SCORM,
H5P, quiz, assignment), a reusable question bank, a grading queue with a visual rubric
grid, a weighted gradebook, and per-learner and per-course progress with CSV export.
For administrators
Roles and capabilities, white-label branding, editable categories and levels, and an
audit log covering 27 action types.
Selling courses
Link a WooCommerce product to a course: the buyer is enrolled on payment and access is
revoked on refund. No external service and no subscription required.
Standards
2 and 2004 import and runtime, with resume and HTTP Range media streaming.
License
Stedica LMS is distributed under the GNU General Public License. The plugin’s own code is
0-or-later.
It bundles third-party components under their own compatible licences, and two of them are
worth naming because they are stricter than the plugin’s own: the Freemius SDK in
0-only, and dompdf’s rendering library in vendor/dompdf/ is
1. 0 without the
“or later” option, because one of its components does not offer it.
txt (included
because WordPress itself is GPLv2-or-later and the directory asks for a compatible licence)
ship in the package. GPLv3 is compatible with that requirement.
External services
This plugin connects to one external service, and only for licensing.
Freemius
Freemius handles licensing, the free trial and update delivery for the optional paid
add-on, Stedica LMS Premium. The licensing SDK is bundled in this plugin.
Nothing is sent until you choose to send it. On a fresh install the plugin runs in
anonymous mode: no request is made to Freemius and no data leaves your site. Requests
begin only when you opt in to Freemius’ service, start the free trial, or activate a
licence key — each of which is an explicit action you take.
Once you have opted in, the following is sent to Freemius:
- when you opt in, start a trial or activate a licence: your site URL, the email address
and name of the WordPress user performing the action, and the WordPress, PHP and plugin
versions
- when checking for updates to the paid add-on, and when validating a licence: your site
URL and the installed plugin version
No learner data, course content, grades or quiz results are ever sent.
If you never opt in, the plugin remains fully functional and contacts nothing. The paid
add-on is the only thing that requires it.

Security
Authorization is enforced server-side on every REST route and every admin screen —
hiding a menu item is never treated as access control. Learner-owned resources are
ownership-checked to prevent enumeration by id. Quiz answer keys never leave the
server. Protected files (SCORM assets, submissions, certificates) are served through a
PHP proxy that derives authorization from the request path, because a SCORM package’s
relative sub-resource requests cannot carry a token. Grades are clamped server-side.
Secrets are masked in every API response, and are encrypted at rest when the PHP
OpenSSL extension is available (it is on virtually all hosts; without it they are stored
unencrypted and only the masking applies).
Shortcodes
For learners: [stedica_my_courses], [stedica_catalog], [stedica_course_player],
[stedica_leaderboard], [stedica_certificates], [stedica_discussions],
[stedica_achievements]
Stedica LMS Premium, a separate add-on, adds [stedica_live_sessions],
[stedica_my_skills], [stedica_learning_paths] and [stedica_membership]. They are
listed here so you know what exists, not offered by this plugin — this package does not
contain them and does not register them.
For staff: [stedica_my_group] shows a group leader their members’ progress, and
[stedica_instructor] gives an instructor their grading queue. Both are safe to put on an
ordinary page — each shows only what the person viewing it is entitled to see, and a
visitor with no such role sees a plain explanation rather than an error.
Every surface is also a block — search “Stedica” in the inserter — and an Elementor
widget, found under a Stedica LMS category with a dropdown for which surface to show.
All three render through the same code, so they behave identically.
