It's definitely not ready to be merged. But you're more than welcome to work on it!

There are some issues to be solved to self host the app:

- the global height (SRTM) data is approx. half a TB, so we need an option to provide only a subset of files for the relevant locations - same for OSM data where some extracted features are stored locally - remove some third party dependencies, such as captcha verification for sign-up etc. - remove hook to Garmin, Coros, Polar API (each user will need to go through each of the companies verification process themselves to get the keys)

Still some work to do...
