<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.
This service is provided by WriteAlt. Terms of service and Privacy policy: https://writealt.com/terms-privacy-policy
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.
