It’s simple buddy 
If you know even a little bit about web development and languages then you can figure out how that works.
Just try to think about it for once

I couldn’t. Please tell me how -_-
There are tons of methods, the easiest way could be…
Just take an array, add few sentences in it (i.e. strings) and access the array elements using a random number generator (use it as index for the array).

I modified it, now it will only increment if someone actually presses the submit button to view their attendance.

There’s another bug and not really a bug but kind of an improvement.
For example sometimes codechef gives 503 error and in that case your tool shows that the person is not present in any of the contests. So I was just saying if you show some error message in that case then that would be better.
Also if there is any other contest which was cancelled or something then you all can post into comments. It will be added to the exceptions.
I only know about two such contests viz. March Cook-Off and May Lunchtime so they have been added.

Please fix the above problem also.
If I am not wrong I guess this error (503) now doesn’t come on Codechef now?

You already have enough karma
But still you can have a look on this thread : "I want to ask a question" - Ask them all here! - meta - CodeChef Discuss
Simply post your queries there.

why can’t I view attendance before 2014?
Since Lunchtimes were started from June 2013 so I thought there was not much need to show attendance before that.

Ok ok. What about the app?
Currently there doesn’t seem for any need of an app for this purpose. Simply having an app for viewing one’s attendance is not enough, then it should also contain features like contest notification and all, only then it would be useful. But such apps already exist, so clearly an app for simply this purpose is not of much use.
Ok ok. I see. Thanks,
I guess since codechef added division system, the script is not able to get the attendances correctly.
