Daphne's dilemma
Daphne In that case, you should be patient. Which is of course already a crucial virtue for the chaste. You hope to be belted for the rest of your life. A laudable goal, but that means it is worth taking the time to find a proper keyholder, even if it takes months or longer.
In the meantime, keysafes or numbered plastic locks are your friend. Numbered locks are a great way to use outside accountability buddies without surrendering control to them — for instance, you could send photos of the lock on occasion to verify that you haven’t taken it off. On cleaning days, send a pic just before you remove it and another a short time later to show you locked it right back on without any hanky-panky.
I already have both of those in fact
Well in answer to your post, I think your wish to enter chastity my means of a mechanical device is reasonable. I would hesitate to advise you to somehow make it permanent (though I am not sure you could do that anyway). But through my own life experience I know that changing one's mind and attitudes is a fairly common event. And while "permanence" might be a worthy goal, my advice would be to keep that as a sort of distant Everest to climb and in the meantime take each day as it comes and enjoy it to the full.
The question of finding a trusted (and hopefully loving) keyholder would seem to me an obvious first step though possibly some sort of time safe option might be viable. I am not really qualified to understand all the in's and outs of using time safes, though perhaps @Tobbe could help?
Foxies people around here have long tended to be a little fluid with the term “permanent,” probably because of the multiple languages spoken and not everyone being fully aware of how specifically loaded a term it is in the fetish boards. But yes, it seems to have settled here into meaning “24/7, no releases, taken off for cleaning and emergencies only.”
Correct
Daphne Again i don't know anyone near me that would hold the keys
i'm sorry for you, but i wouldn't give the keys to a stranger. there are boxes where you can keep the keys and set a time when the box should open again, maybe that would be an idea, at least until you have found a suitable key holder.
it seems we have similar ideas 
Saintprudence “24/7, no releases, taken off for cleaning and emergencies only.”
this is how I understand it
Daphne do you have an upper limit to how long you remain belted in a relationship, or do you hope for it to be indefinite?
The latter, but if there has to be a limit i can live with it
Daphne since this is specifically your thread, I feel more okay asking broader questions. What’s your everyday routine like? I don’t mean location or identifying info, but rather, classes, job, living arrangements and so forth.
Well usually I wake up at 8,do my morning routine and work on school until 4-5. Have dinner, do dishes and afterwards i can spend time on hobbies
Daphne what’s your living situation? Parents or on your own or roommates?
Daphne When i have more dresses for it
Yes,your clothes should be adapted to hide it.If necessary,you may wait until you get more adapted ones,or go do some shopping!
I agree.
I agree about it too.
Saintprudence it is worth taking the time to find a proper keyholder, even if it takes months or longer.
Right.
Saintprudence “24/7, no releases, taken off for cleaning and emergencies only.”
Yes.
Parents
Daphne a thought, then: you might review how much you do around the house and figure out what additional domestic chores you might take on.
you’re 23, so they probably couldn’t actually stop you on anything, but I assume living with parents will not be an impediment to chastity? You’ve indicated they know about it but won’t be involved.
Correct, i won't have issues from being in chastity
