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.

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.

Change Log
2.1.10
- Corrected outdated documentation claiming the price widget itself was English-only — the widget has supported Finnish (in addition to English) since 2.1.6’s lang-parameter groundwork, switching automatically based on the visitor’s selected country. Updated the readme’s Translations section and the admin settings page’s Plugin Language field description to describe this accurately.
2.1.9
- Renamed internal prefix from “sew_” to “saveel_” throughout (functions, constants, CSS classes, script/style handles)
- Removed the Domain Path header (pointed to a languages folder that no longer exists now that bundled translation files have been removed — flagged by Plugin Check)
- Removed bundled Finnish translation files — WordPress.org manages translations automatically via translate.wordpress.org once the plugin is approved
- Admin settings page no longer auto-loads an iframe for the live preview — replaced with a plain link that opens the preview on saveelectro.com in a new tab
- Front-end CSS/JS now properly registered and enqueued via wp_enqueue_style()/wp_enqueue_script() with wp_add_inline_style()/wp_add_inline_script(), instead of being echoed directly as inline / tags
2.1.8
- Fixed Plugin URI and Author URI being identical (WordPress.org submission requirement) — Author URI now points to the developer’s WordPress.org profile
2.1.7
- Removed the manual load_plugin_textdomain() call (discouraged since WP 4.6) — translations now load automatically via the Text Domain / Domain Path headers, per WordPress.org Plugin Check
- Confirmed compatible with WordPress 7.0
2.1.6
- Added a manual “Plugin Language” switcher to the settings page (overrides site language for the plugin’s own admin text)
- Widget iframe URL now passes a lang parameter, ready for future widget-side localisation
2.1.5
- Full i18n pass: every admin and front-end string now uses standard WordPress translation functions
- Added bundled Finnish (fi) translation
- Plugin is now translation-ready for future languages via the /languages folder
2.1.4
- Primary shortcode is now [saveelectro]; [saveelectro_prices] still works as an alias
2.1.3
- Unified display name to “SaveElectro” across plugin, menu, block and widget
2.1.2
- Added anonymous, cookieless usage analytics (no personal data, no IP stored)
2.1.1
- Credit link now aligns flush under the widget
2.1.0
- Added optional, off-by-default credit link below the widget
