Website, documentation & Demo
Wetterwarner Supporter license
Wetterwarner is and remains free – with all features and the same official DWD data for everyone. It is developed and maintained in my spare time, and the Wetterwarner API that supplies the data to every installation has real running costs. The optional Wetterwarner Supporter license is a way to directly support that ongoing development and operation – and as a thank-you, it also gives your site a few practical extras:
- Faster updates: new warnings every 5 instead of 15 minutes
- Fallback server: if the main API is unavailable, your site automatically switches to a separate, independently hosted server
- Priority support via contact form or e-mail
Launch offer: 19 € per year (regular price 29 € per year). One-time purchase for 12 months, no subscription, no automatic renewal. The license is tied to your website’s address and is activated automatically with the next update – no license key to copy.
Get your Supporter license – or directly from “Settings > Wetterwarner” in your WordPress admin.
External services
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 – every 15 minutes (every 5 minutes with a Supporter license), 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.
