<h3>External services</h3>
This plugin connects to the WriteAlt API at https://writealt.com/api/v1 to validate the configured API key, retrieve account and credit information, and generate alt text for selected images.
When testing the connection or refreshing account information, the plugin sends the configured WriteAlt API key. When alt text is generated, the plugin sends the selected WordPress image attachment URL, selected language, selected writing style, optional keywords, and the configured API key. If automatic generation on upload is enabled, the same image URL and generation settings are sent when a new image attachment is uploaded.
The WriteAlt API response is used to display account information and save generated alt text to WordPress attachment metadata. The plugin does not send analytics or tracking data.

Image compression and WebP conversion run locally in the user’s browser or WordPress environment. The plugin includes its compression script locally and does not load compression files from an external CDN.

<li>Generates alt-text — descriptive, keyword-rich alt-text in 7 languages</li>
<li>Converts format — WebP, JPEG, or PNG</li>

<h3>External services</h3>
This plugin relies on the SEOPix API (seopix.co) to process images. Without this service the plugin cannot compress images, generate SEO filenames, or produce alt-text — all image analysis and AI processing happens on SEOPix servers, not on your WordPress site.
SEOPix API — https://www.seopix.co/api
What it is used for: compressing images, generating SEO-optimized filenames from image content using AI, generating multilingual alt-text using AI, and checking the remaining credit balance on your SEOPix account.
What data is sent and when:
<ul>
<li>When an image is optimized (either automatically on upload, manually via the “Optimize” button in the Media Library, or through the “Optimize with SEOPix” bulk action), the plugin sends a <code>POST</code> request to <code>https://www.seopix.co/api/process-single</code> containing: the image file binary, your SEOPix API token (as a Bearer token in the <code>Authorization</code> header), and the optimization options you configured in Settings → SEOPix (platform preset, output format, alt-text language, filename language, and optional max width/height). The request also includes a <code>source</code> field set to <code>"WordPress plugin"</code> so SEOPix can track plugin usage.</li>
<li>When the Media Library, Settings page, or WordPress admin bar loads (and an API token is configured), the plugin sends a <code>GET</code> request to <code>https://www.seopix.co/api/auth/extension</code> with your API token in the <code>Authorization</code> header, in order to retrieve and display your current credit balance.</li>
<li>After an image is processed, the SEOPix API returns a temporary signed URL pointing to the optimized image stored on SEOPix’s own CDN (hosted on <code>seopix.co</code>). The plugin then fetches that URL with a <code>GET</code> request to download the optimized image and replace the original in your Media Library. No additional user data is sent in this download request.</li>
</ul>
No personal information about site visitors, site administrators, post content, or any data other than what is listed above is ever transmitted. The plugin never contacts any other third-party service.
