Chastity and orgasm denial discussion

Well its as simple as the title, my first chastity is arriving this week and me and my master were looking for ways to prevent me from chickening out since its an online relationship. Now I stumbled upon emlalock today, for people that don’t know it, its basically a timer with a bunch of options and extras, that releases you after it hits 0 by giving you the code of a combination lock which is locking your keys or directly on your chastity. (Change the combination while blindfolded and on skype so my master/keyholder can see it, after that scramble it. And he can set up the site. Now I’ve been testing it a bit and emlalock has so many settings and I’m not sure how to get so that it works for us. Essentially my master/kh wants to have a visible timer for me, with a daily roulette that 1/6 subtracts 12 hours, 1/6 subtracts 6 hours, 1/6 nothing, 2/6 add 12 hours, 1/6 add 24 hours. Now he should be able to add, the maximum time should be 1 month just in case, and minimum 0, now I think we can get that but were confused about other people adding/subtracting time, is it possible to turn this on or off or limit it? We want it strictly just him adding and subtracting, the daily wheel and that is it. All help is appreciated.
