Hello Batman2287, thanks a lot for your positive feedback! At the moment there is no option to change the units. But I will note it and check what I can do for the next updates. Kind regards

Hello, that is a good point. Let me explain the usage of data. It is correct that we get some data, but only for monitoring."Location" is only about the country. Means - we see "100 users from US; 40 from France; 20 in Germany; etc.".We provide our apps in 11 different languages. The country data help us to see where the app is used and if some problems occur that might have something to do with language localization.Maybe that "device ID"-thing might be another scary factor. But this only shows the difference if the app was launched the first time or if users come back. This is only a pale numbers that helps us to understand if people just downloading, open once and say "yeah, remove that s*$t" or if there is a real use. Some information help us to understand that teachers and parents are using these apps too. At first we designed the apps only for pupils. But the data are only some simple numbers too like "40% are in age of 25-35; 20% in 36-45; etc".The rest are crashes and some things to check if the app works properly."Uncontrolled 3rd parties" - we use Firebase for this. In the end it is Google who is managing this, but they say they only monitor the data. That is the only information that we get.From our point of view we only use data to improve the service. But we use a 3rd party that is connected to Google. It is up to you if you trust Google.I hope I was able to provide some clarity. Kind regardsPs. Let me tell you that I nearly get the same information from my apple developer console. So yeah ... everything the same.----Thank you very much for updating your review. 🙏
