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: backpackr https://www.dropbox.com/s/0sd5txstnwagzsb/res_back.png?dl=0 You can get email, facebook ID and password of any user over cleartext http travelmate https://www.dropbox.com/s/xopdo2rx0tem30r/res_travelmate.png?dl=0 http, email, facebook_id booola https://www.dropbox.com/s/u8y811yfupeuo1b/res_booola.png?dl=0 emai, facebook_id trippers https://www.dropbox.com/s/xkh62i5pg5rbe1v/res_trippers.png?dl=0 emai, facebook_id outbound https://www.dropbox.com/s/hjw1fpts5xaeons/res_outbound.png?dl=0 email party with a local https://www.dropbox.com/s/hunjtgvo46p24b7/res_party.png?dl=0 email Is it a normal practice?
