Topic subscriptions
Topic subscriptions offer safety-relevant information on a range of topics. As soon as KATWARN has been installed on the smartphone, specific topic subscriptions are available for download. This particular service can be used independently from the location settings.
Depending on the topic, they either run continuously or expire after the event. You can also (de)activate or delete these subs from the KATWARN app menu at any time.
