Permission to use Blitzortung real-time data for GdzieGrzmi.pl

[gdziegrzmi.pl]

Hello,

I am developing GdzieGrzmi.pl, a free and non-commercial Polish website for monitoring thunderstorms and lightning activity in Poland and Europe. I would like to ask specifically about the Blitzortung real-time WebSocket stream.

Is it permitted to use the Blitzortung WebSocket to receive real-time lightning data for an external website such as GdzieGrzmi.pl?

We would like to use only one server-side WebSocket connection. The received lightning data would be processed on our server and temporarily stored in our database. Website visitors would not connect directly to Blitzortung servers.

The planned architecture would be:

Blitzortung WebSocket → one server-side collector → our database → our WebSocket → GdzieGrzmi.pl users

The data would be used to provide a live lightning map, precipitation radar integration, thunderstorm activity statistics, active storm areas, nearby storms and heatmaps. The public map would display lightning strikes from the last 60 minutes, and the data would be retained in our database for approximately 24 hours.

We would clearly display Blitzortung.org as the source of the lightning data and comply with any attribution or technical requirements.
Could you please confirm:

1. Are we allowed to connect to and use the Blitzortung real-time WebSocket for this purpose?
2. Are we allowed to temporarily store and process the received data on our server?
3. Are we allowed to redistribute the processed data to visitors through our own WebSocket/API?

If permission is required, we would be happy to request it formally.

Thank you for your time and for maintaining the Blitzortung network.
Best regards,
GdzieGrzmi.pl

Blitzortung is not a general-purpose public lightning-data service or API provider.

The network exists primarily for participating station operators and the cooperative lightning-location project itself. Its data is not offered as a general source for private applications, websites, hobby projects, research tools, AI-assisted projects, or other third-party services.

Publicly available Blitzortung maps and related services may be used where appropriate. Direct access to the underlying lightning data is not provided for general third-party use.

If your project requires a general source of lightning data for use in your own application or service, you should look to a provider whose purpose is to supply that type of data.
