There is the OSM Scout Server project, that makes it possible to download various OSM based data packs for offline use: https://github.com/rinigus/osmscout-server https://github.com/rinigus/osmscout-server Then it provides various services (routing, PoI search, geocoding, etc.) over this data set to all applications running locally on your machine. It targets mainly various mobile Linux distros but works perfectly fine on desktop as well and is available in flatpak form. Like this all navigation and mapping can share the same data set and no potentially sensitive location related metadata is leaked to a remote server other than what data packs have been initially downloaded. Also the community run infrastructure just needs to be able to store and store and distribute the ~150 GB of data packs covering Earth but does not need to have any extensive compute and memory requirements to handle lots expensive of individual API queries.
