hi, i'm a fisherman and the only wifi or data connection i can use is through proxy with authentication, I can use chrome to access the web on my htc one m8 but I can´t use any of the other apps i have. is there a way, a app or something, for me to use this proxy server to access my other apps. like snapchat, instagram, the facebook app etc.?
sorry for my bad english

There are 3 totally different things that are called proxy servers. From what you're describing, keeping a browser open and logged in might work, but the proxy has to have authentication to accept your device, so just running an app won't work. (It also may not work, even if you keep a browser logged into the proxy server.) If this is a "satellite wifi to the ship via proxy" sort of thing, someone needs to pay a real technician a little money to set it up so you don't need to go through a proxy server. (It can be secure without a proxy server - all it can't be is encrypted, but how many boats are going to be hanging around trying to break into your ship's wifi?)

Your English is about as good as any non-techie American (and better than some) - there's nothing for you to apologize for.
