A drinking-water label is a starting point
A tagged drinking-water amenity or an explicit drinking_water=yes value provides the basic candidate signal. Participating refill establishments can use drinking_water:refill=yes. The tool accepts those signals while rejecting explicit negative drinking-water tags.
Real conditions can change after the map record was edited. Seasonal shutdowns, maintenance and access restrictions may not be reflected immediately. The application presents the source rather than converting community metadata into an inspection claim.
Missing tags must remain unknown
The absence of fee=yes is not equivalent to free water. The broad default excludes known paid points but shows unknown fee status. The stricter free filter requires an affirmative free-water signal. Similar care applies to bottle clearance, opening hours and indoor access.
Opening-hours strings are shown as source text. The app does not implement a full opening-hours interpreter or claim that a stop is open now. Review the hours in context, including holidays and seasonal conditions, before depending on a single location.
Preserve the source when sharing
The source date describes a data snapshot. An element edit timestamp describes a map edit, which could have changed a name or another field; neither is proof of a recent water test. Keep that distinction visible when giving a trip card to another person.
Exports include OpenStreetMap contributor attribution and the ODbL link. The downloadable regional extract makes the underlying selection inspectable. If you correct map information, use the appropriate source workflow and your own observations rather than copying from an incompatible third-party map.
