<p>AstroChart adds an interactive natal chart calculator and SVG wheel to any page via shortcode. The default calculation engine runs locally on your server. No API key, no recurring HTTP, no third-party SaaS. Two optional engines are available for higher precision or experimental NASA-source calculations, all documented under “External services” below.</p>
<h4>Built for</h4>
<ul>
<li>Astrology consultants who deliver birth charts to clients and need a private, professional embed on their pro site</li>
<li>Astrology schools and editorial portals that publish charts and want full visual control without a recurring per-chart cost</li>
<li>Developers who want a clean shortcode, customizable engine, and an open source calculation library</li>
</ul>
<h4>What it does</h4>
<p>Drop a shortcode on any page:</p>
<pre><code>[astrochart_chart date="1990-05-16" time="08:45" timezone="Europe/Rome" lat="45.46" lon="9.19"]
</code></pre>
<p>The page renders an interactive SVG wheel, planet/house/aspect tables, and an optional input form for site visitors.</p>
<h4>Calculation features</h4>
<ul>
<li>Three interchangeable engines: pure-PHP Core (default, always available), pre-computed Table (sub-arcsecond, optional one-time data download), experimental JPL Horizons (NASA real-time)</li>
<li>7 house systems verified against an independent astronomical reference: Placidus, Koch, Regiomontanus, Campanus, Porphyry, Equal, Whole Sign</li>
<li>13 bodies: Sun..Pluto plus Chiron, Mean Node, and Mean Lilith</li>
<li>Natal chart, Ascendant-only, and Solar Return calculations</li>
</ul>
<h4>Display and customization</h4>
<ul>
<li>Interactive SVG wheel with zodiac bands, house lines, planet markers, aspect lines, and on-wheel filters</li>
<li>Visual configurator with live preview, JSON import/export, theme presets</li>
<li>CSS override via shortcode for per-instance styling</li>
<li>Custom orb values per aspect type via shortcode or optional form</li>
<li>Stack or tabbed layout for result panels</li>
<li>Planet, aspect, house/cusp, legend, and calculation data panels</li>
</ul>
<h4>Developer integration</h4>
<ul>
<li>WordPress filters to customize chart output at any stage</li>
<li>Open source calculation engine (BSD 3-clause): https://github.com/simopa/AstroPHP</li>
<li>Configurable geocoder with Nominatim default (no key) and optional API-key providers</li>
</ul>
<h4>Languages</h4>
<p>Italian, English, Spanish translations included.</p>
<h4>Shortcodes</h4>
<ul>
<li>[astrochart_chart] – full natal chart with form, wheel, and data tables</li>
<li>[astrochart_ascendant] – Ascendant-only calculation</li>
</ul>
<h3>External services</h3>
<p>AstroChart can work with the local Core calculation engine and manually supplied coordinates without sending data to external services. The following optional services may be used depending on site settings and user/admin actions.</p>
<h4>Geocoding providers</h4>
<p>AstroChart resolves place names to latitude/longitude through the selected geocoding provider. The plugin sends the place search text, optional country bias, and a plugin user agent to the selected geocoding provider. If the selected provider requires an API key, the API key is stored in the site’s WordPress options and sent with each request to that selected provider. Birth dates, birth times, names, and full chart results are not sent to geocoding providers.</p>
<p>Geocoding happens when a visitor submits a chart form with a place name and no coordinates, or when a shortcode supplies a place name without coordinates.</p>
<p>Geocoding does not happen when latitude, longitude, and timezone are supplied directly in the shortcode or form. Geoapify, LocationIQ, Google Maps, and Mapbox are used only if an administrator selects that provider and enters the required API key.</p>
<p>Supported geocoding services:</p>
<ul>
<li>Nominatim / OpenStreetMap – used for geocoding place names. Usage policy: https://operations.osmfoundation.org/policies/nominatim/ Privacy policy: https://osmfoundation.org/wiki/Privacy_Policy</li>
<li>Geoapify – optional geocoding provider. Terms: https://www.geoapify.com/terms-and-conditions/ Privacy policy: https://www.geoapify.com/privacy-policy/</li>
<li>LocationIQ – optional geocoding provider. Terms: https://locationiq.com/tos Privacy policy: https://locationiq.com/privacy</li>
<li>Google Maps Geocoding API – optional geocoding provider. Terms: https://cloud.google.com/maps-platform/terms Privacy policy: https://policies.google.com/privacy</li>
<li>Mapbox Geocoding API – optional geocoding provider. Terms: https://www.mapbox.com/legal/tos Privacy policy: https://www.mapbox.com/legal/privacy</li>
</ul>
<h4>GitHub Releases</h4>
<p>If an administrator selects the Table engine and clicks the ephemeris download button, AstroChart downloads <code>planets.bin</code> and <code>moon.bin</code> from a GitHub Release of the AstroPHP project. This sends a standard HTTP request from the server to GitHub, including the server IP address and user agent. It does not send visitor birth data or chart data.</p>
<p>Service provider: GitHub. Terms: https://docs.github.com/site-policy/github-terms/github-terms-of-service Privacy statement: https://docs.github.com/site-policy/privacy-policies/github-general-privacy-statement</p>
<h4>NASA JPL Horizons</h4>
<p>If an administrator selects the experimental JPL Horizons engine, AstroChart requests ephemeris vectors from NASA JPL Horizons during chart calculation. Requests include the requested body identifier and calculation time/Julian date. They do not include names, email addresses, full form submissions, or rendered chart tables.</p>
<p>Service provider: NASA/JPL Horizons. API documentation: https://ssd.jpl.nasa.gov/horizons/ Privacy policy: https://www.nasa.gov/privacy/</p>

<h3>External services</h3>
<p>This plugin connects to <strong>api.astroway.info</strong>, the AstroWay Calculation API operated by the AstroWay Team, to render astrology widgets and tarot readings. No external request is made until a widget is actually rendered on a page where one of the plugin’s shortcodes or Gutenberg blocks is used.</p>
<p><strong>What is sent:</strong></p>
<ul>
<li>When a natal chart, bodygraph, or transit widget renders: the parameters provided in the shortcode (date, time, latitude, longitude) plus the visitor’s IP address (for anonymous rate-limiting).</li>
<li>When a daily horoscope, moon phase, or daily tarot widget renders: the zodiac sign or deck identifier plus the visitor’s IP address.</li>
<li>When the site administrator clicks “Verify Key” or “Test Connection” in the Settings screen: the configured API key and a small diagnostics payload.</li>
</ul>
<p><strong>When this happens:</strong></p>
<ul>
<li>On frontend page render (only on pages where an AstroWay shortcode or block is present).</li>
<li>On explicit admin action (Verify, Test Connection, Purge Cache).</li>
</ul>
<p><strong>No data is sent on plugin activation, deactivation, or admin pages without explicit user action.</strong></p>

<h3>Privacy</h3>
<p>This plugin stores the following on the WordPress site:</p>

<li>The site administrator’s API key (if entered), stored in the <code>wp_options</code> table under <code>astroway_settings</code>. Visible only to users with <code>manage_options</code> capability.</li>
<li>WP transient cache of API responses (prefix <code>astroway_v1_</code>) to reduce repeat external calls. Cache contents are chart/horoscope/tarot output — no visitor PII beyond what was submitted via shortcode arguments. Purged via Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> AstroWay <span aria-hidden="true" class="wp-exclude-emoji">→</span> Purge Cache.</li>
