Marivya Lesson Planner helps private teachers keep track of their students, lessons and shared materials. 
It includes a minimal Student Portal that students can open via a magic link (token) or PIN, so they can see upcoming lessons and notes without creating an account.
Highlights 
– Custom post types for Students, Lessons, and Materials 
– Calendar-friendly lesson data (date, time, duration, status) 
– Materials linked to a student or global 
– Student Portal access via magic link (token) or PIN 
– Rate-limited PIN attempts and HMAC-signed session cookie 
– Admin AJAX for moving lessons on a calendar 
– WordPress privacy integration: personal data exporter and eraser 
– No telemetry. No external services required.
Pro (optional add-on) 
– Recurring lessons, advanced reminders, templates, richer student portal, and more. 
– A gentle “Pro” upsell is shown only on plugin screens (no global banners).

<h4>How it works</h4>
<ol>
<li>Create a Student and start adding Lessons (date, time, duration, notes, homework).</li>
<li>Optionally attach Materials to a student.</li>
<li>Open a student and use the Student Portal access box to:

<li>Generate a magic link (time-limited token) and copy/send it,</li>
<li>Or set a PIN (hashed and never emailed).</li>
</ul>
</li>
<li>Students access the portal from the link or by PIN. A secure session cookie keeps them logged in for 30 days.</li>
</ol>
<h4>Privacy</h4>
<ul>
<li>Includes a personal data exporter and eraser (<code>Tools → Export/Erase Personal Data</code>).</li>
<li>Student portal session cookie: <code>marivya_lp_portal</code> (HTTP-only, SameSite=Lax, Secure on HTTPS), expires in 30 days.</li>
<li>Magic links expire after a chosen number of days (default 7).</li>
<li>No personal data is sent to third parties.</li>
</ul>
