External services

This plugin relies on the Wetterwarner API (api.wetterwarner.de), a service operated by the plugin author. The API caches the official warnings of the German Weather Service centrally, so that not every website has to download the DWD data, which can be several megabytes in size.

All requests are made server-side by your WordPress installation – at most every 5 minutes, with all regions in use combined into a single request. Visitors of your website never connect to external servers. No data about the visitors of your website is transmitted.

Optional: support development – Only if you explicitly agree (notice in the admin area or “Settings > Wetterwarner”), the address of your website as well as the plugin, WordPress and PHP versions are additionally sent with the regular request. You can revoke your consent at any time; the stored information is then deleted. Entries without contact are removed automatically after 90 days.
