Using Shortcodes:
Basic usage:

Common examples:

 [vareon type=”savings” theme=”modern”] 
 [vareon type=”bmi” branding=”0″]
Shortcode Parameters:
<ul>
<li><code>type</code> – Calculator type: <code>loan</code>, <code>mortgage</code>, <code>savings</code>, <code>credit-card-payoff</code>, <code>roi</code>, <code>discount</code>, <code>tip</code>, <code>bmi</code>, <code>age</code>, <code>percentage</code>, <code>unit-converter</code>, <code>fuel-cost</code>, <code>gpa</code>, <code>grade-calc</code></li>

<h3>Troubleshooting</h3>
<h4>A calculator is not showing</h4>
Make sure the plugin is active and the calculator type is valid. Test with a known shortcode such as <code>[vareon type="loan"]</code>.
<h4>Changes are not appearing</h4>
Clear any caching, optimization, or CDN layer and refresh the page.
<h4>The block uses the wrong style</h4>
Check whether the block is using the global default theme or a block-level override.
<h4>Shortcodes work in one area but not another</h4>
Some page builders restrict shortcode execution in certain regions. Try a shortcode block or use the native Vareon block instead.

<h3>External Services</h3>
This plugin does not connect to any third-party services. All calculations run locally in the visitor’s browser.
Links to vareon.dev, including documentation, branding, privacy, and the optional admin-only Pro Waitlist page, are standard links that a user may choose to click. Support is handled on WordPress.org. The plugin does not automatically send calculation data or waitlist data to those URLs.

<h3>Data Storage & Privacy</h3>
Cookies: This plugin does not set cookies.
Browser localStorage (functional): 
* <code>vareoncalc_measurement_mode</code> – Stores the visitor’s preferred measurement system on calculators that support both metric and imperial units. 
* <code>vareoncalc_lite_preview_v2_state</code> – Stores administrator-only settings preview preferences in wp-admin (selected calculator type, preview width, zoom level, and pan position) for convenience.
WordPress Database: 
* Site options: Theme preferences, currency settings, measurement settings, branding, review prompt state, and related plugin configuration 
* User meta: Dismissal preferences for admin notices and tips 
* Transients: Short-lived flags used for activation redirects
No telemetry or tracking: This plugin does not collect usage analytics or personal data. All calculations happen in the browser. The admin-only Pro Waitlist tab is just a link to vareon.dev.
Uninstall cleanup: Deleting the plugin from the WordPress admin removes stored plugin data from the database. Browser localStorage can be cleared from the browser itself.
