<h3>External Services</h3>
This plugin sends data to the ALTification API and Anthropic (Claude) when you trigger a generation, scan, or credit check — never automatically in the background.
<h4>ALTification API</h4>
Endpoint: https://altification.ai/wp-json/altification/v1/
When you generate, the plugin sends:
<ul>
<li>Your image (as a URL or base64-encoded data)</li>
<li>The page’s SEO context (focus keyword, meta title, meta description, where available from your SEO plugin)</li>
<li>Your site’s context (site name, language, WooCommerce product/category data if relevant, a short excerpt of your homepage text, ACF field content if you have configured ACF support)</li>
<li>A non-identifying site fingerprint (an MD5 hash of WordPress’s COOKIEHASH and site URL, used to lock your API key to one site)</li>
<li>Your ALTification API key</li>
</ul>
The API returns the generated text, your remaining credit balance and your account status.
ALTification does not store the image after the response is returned.

<li>ALTification Terms of Service: https://altification.ai/terms/</li>
</ul>
<h4>Anthropic (Claude)</h4>
ALTification’s server uses Anthropic’s Claude API to produce generated text. The plugin does not call Anthropic directly — no Anthropic account or key is needed.

<li>Anthropic Privacy Policy: https://www.anthropic.com/legal/privacy</li>
<li>Anthropic Commercial Terms: https://www.anthropic.com/legal/commercial-terms</li>
