For start I will say "sorry" if I write in wrong section, but I really don't know German

I'm geocacher from Poland, and I'm make app for geocaching. I want to release German version too, but as I say, I don't speak in your language. There is only few sentenses and some words to translate, so I thought you can help me?
I prepared sheet with all texts that are used in my application, so if you have some time (it's really about 10 minutes), I will be grateful for help. Of course pplication will be avaible for free (in Google Play).
Here is a sheet: https://docs.google.com/spreadsheets/d/ ... edit#gid=0
Thank you in advance
