Third-party Providers & Tools

Meteostat uses different third party service providers and tools for the provision of its services.


Meteostat uses services from Cloudflare (Provider: Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA). Cloudflare operates, among other things, a content delivery network (CDN) and a firewall for websites. Thereby, the data transfer between Meteostat and the user is handled via Cloudflare's infrastructure in order to fend off attacks and to ensure a secure & stable use of our offers. For this purpose, Cloudflare also uses technically necessary cookies. This represents a legitimate interest within the meaning of Art. 6 para. 1 lit. f GDPR.

For more information, please see Cloudflare's privacy statement:


For statistical analysis Meteostat uses the open source software Matomo. With the help of this tool, we analyze the use of our offers. As a matter of principle, we do not use tracking cookies in order to protect the privacy of our users. Furthermore, we only store IP addresses in anonymized form. This data is stored on Meteostat servers in Germany. The data is not passed on to third parties at any time. If you would like to generally prevent the storage and analysis of your usage data, you can deactivate Matomo here. This will set an opt-out cookie, which prevents your usage data from being stored. Please note that you must deactivate the cookie again after deleting it.

Services for Developers

Meteostat also provides historical weather and climate data via so-called application programming interfaces (APIs). These interfaces are in principle subject to the above-mentioned data protection provisions. Furthermore, the following additions apply.


The use of the Meteostat JSON API requires prior registration. In the process, the e-mail address, as well as the first and last name of the user are collected and stored. The email address is stored to protect against automated registrations. We record first and last names for personal addressing, as well as for possible identification in case of criminal misuse of our offers. In addition, we store the IP address, as well as the date and time of registration. This data is stored to prevent multiple registrations. The measures to prevent (automated) multiple registrations serve to protect our infrastructure and therefore represent a legitimate interest within the meaning of Art. 6 (1) f GDPR.
