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

party with a local https://www.dropbox.com/s/hunjtgvo46p24b7/res_party.png?dl=0 email
Is it a normal practice?
