Gypsum lets you upload tracks from your GPS (or something) using GPX format, stores them in a database and displays them on a map together with a bunch of statistics.

Multiple users are supported, you can get basic statistics for each user per month, etc.

Gypsum is written in Python with Django.

Gypsum is a pretty basic Django app. If you know your way around Django, there shouldn't be any surprises.

In settings.py, I have made it possible to break out sensitive stuff like database configuration and passwords (to avoid uploading them to GitHub, like I did). Secrets are put in a file called secrets.py in Gypsum's directory. Example of contents for secrets.py:

databases = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'gypsum',
        'USER': 'gypsum',
        'PASSWORD': 'Tr0ub4dor&3',
        'HOST': 'my.db.host'
    }
}
