<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>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.

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.
