External services
This plugin displays an electricity-price widget that is loaded from SaveElectro.com, an external service operated by SaveElectro.
What the service is and what it is used for
The widget itself (the price chart and figures) is served from https://www.saveelectro.com/widget/embed.html and embedded on your page in an iframe. The widget reads live Nord Pool electricity prices from the SaveElectro API at https://www.saveelectro.com/wp-json/saveelectro/v1/summary.
What data is sent and when
When a visitor views a page containing the widget, their browser loads the widget from saveelectro.com. As with any embedded web content, the visitor’s browser makes a request to saveelectro.com, which means their IP address and standard browser request headers are visible to that server for the purpose of delivering the widget. The plugin does not collect, store, or transmit any personal data itself, and no account or login is required.
The widget records anonymous, aggregated usage events (for example: that a widget was viewed, that a country was switched, or that the SaveElectro link was clicked) so we can understand how the widget is used. These events contain no personal data, set no cookies, and store no IP addresses. The country of the viewer is recorded only at a coarse country level derived from network information, never an IP address.
The selected country and theme are passed in the widget URL (for example ?country=FI&theme=dark) so the correct prices are shown. No personal information is included.
Separately, when the plugin is activated (and again after any update), the site owner’s own browser sends a one-time notice to saveelectro.com containing only this site’s domain name and the installed plugin version, so we can maintain an accurate count of active installations. This contains no visitor data and no personal information — it identifies the site, not any individual.

Translations
SaveElectro is fully translation-ready (all admin and front-end text uses standard WordPress i18n functions with the text domain saveelectro).
By default the plugin follows your site’s own language (Settings -> General -> Site Language in wp-admin), the same as every other WordPress plugin. If you need the plugin’s own settings page in a specific language regardless of the site’s language, use the Plugin Language dropdown at the top of the SaveElectro settings page.
There are two separate things that get translated, worth understanding as distinct:
The price widget itself (the live numbers, chart, status labels, and savings advice inside the box) already supports Finnish today, automatically — it switches language based on the visitor’s selected country (Finland shows Finnish) or an explicit language parameter, independent of anything below. This is built directly into the widget, not delivered through WordPress.org’s translation system, so it works right now with no action needed from site owners.
The plugin’s own admin settings page and this readme follow WordPress’s own translation system (translate.wordpress.org) instead, the same as every other WordPress.org plugin. These are translated separately from the widget above, and availability depends on community/maintainer translation progress there.
Available languages for the widget itself:
English (default)
Finnish
Estonian, Swedish, Norwegian, Danish, Latvian and Lithuanian are planned for the widget. For the plugin’s own admin text and this readme, translations are handled entirely through the plugin’s own project on translate.wordpress.org — WordPress automatically downloads and applies any language with an available translation there, with no action needed from site owners. Community translators are welcome to contribute directly on that platform.
