Show HN: It is too easy to get your private data stolen if you are a traveler

Having traveled with my older brother in Italy, I realized there is no good app for finding travelers who speak your language. For example, at Naples, we couldn't find many people who speak English at all. When I moved to the Netherlands I've got a new problem - it was hard to find people who speak my native language.

So I decided to develop an app.

But before doing it, I analysed market of existing products. I quickly found a bunch of competitors and started to research them. I was surprised that a lot of applications share private data of users, some of them share even passwords.

Here are a few examples of iOS apps, and the pictures will say everything for themselves:

Is it a normal practice?
