<h3>Notes</h3>
<ul>
<li>This plugin uses the free Google Translate service</li>
<li>Translations are performed by Google and may not be perfect</li>
<li>Recommended for sites with static content</li>
<li>For e-commerce or dynamic sites, consider a professional translation plugin</li>
</ul>
<h3>External Services</h3>
This plugin uses the following third-party service. By using the plugin, you and your site visitors accept that this service may receive data as described below.
<ul>
<li>
Google Translate (translate.google.com)
</li>
<li>
What it is used for: The plugin loads Google Translate on your site so that visitors can choose a language and see the page content translated. Translation is done by Google in the visitor’s browser.
</li>
<li>
What data is sent and when: When a visitor loads a page that shows the language selector, the plugin loads a script from Google (translate.google.com). When the visitor selects a language other than the default, the visible page content may be sent to Google’s servers to be translated. This includes the text and structure of the page that the visitor is viewing. No data is sent until the visitor uses the language selector. The plugin does not send personal data to Google on behalf of the site owner; any data sent is the same as when a visitor uses translate.google.com directly.
