* Auto update and notifications — background real-time data fetching and storage change notifications

Data sources: The app fetches official dam data published by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) of Japan. Real-time data is fetched by default via sudmonitor (https://sudmonitor.kusugami-lab.net), a self-hosted, non-official caching relay of the same MLIT data; the official MLIT sources can be selected instead in the app settings. Daily historical data is provided through the sudmonitor relay only. This app contains no ads, trackers or analytics.

Anti-Feature (NonFreeNet): the default connection to the self-hosted sudmonitor relay is classified as a non-free network service.
