StreetComplete makes contributing to OpenStreetMap easy and fun by turning contributions into “quests” on a map for you to complete. No personal information is required, just create an OpenStreetMap account, and start contributing directly in your area!
I tried this out myself, and it is truly fantastic! I had never heard of it, and I’m sure many of you haven’t either, so spread the word!
Tip: When entering buildings to ask questions (opening hours, etc.) be ready to explain what OpenStreetMap is :)
Over time I’ve grown very concerned about non-FOSs simply due to constant datamining. Including for products people buy, they still want customers to install a proprietary app and register the product with serial, name, etc, for extra functionality. So on a phone, I have hard restrictions on what I refuse to install so that no apps have access to anything on phone or how I use it.
In that case … you could install StreetComplete without concern.
