I think you have the right to do anything you want. However, you might want to loosen up a bit. Here's why:
She's going to be on her own entirely in a year, right? Unless you think she'll be living at home and commuting to college locally, she'll likely be on a college campus or in her own apartment. With no one to report to/check in with! That kind of freedom can be overwhelming to someone who hasn't had any of it, and she might actually not do so well with it. So if we expect our kids to magically jump into 100% independence, we need to let them screw up a little (or a lot) when we're still nearby to pick up the pieces. She'll either do great (since she's already responsible and maintaining grades and a job), or she'll drop the ball and you'll be able to help her restructure her thought process or scheduling or judgment or whatever it was that was off. Or, she'll do it on her own without you ever having to say "I told you so."
When I dropped my son off at college, I went to the parent orientation and was told, nicely, that my job was done except to pay bills. There were plenty of parents in deep shock to hear that they were not to call professors, not to call RAs, not to call Health Services, not to call the dean to see what was up. They were a mess. And many of their kids didn't do so hot. One of my son's friends never used an ATM until senior year because his mom drove 3.5 hours each way every few weeks to bring him cash. Really! So, I think it was easier for us and also that our son adjusted more easily because we had opened up the doors a bit during senior year.
So, perhaps if she's just at school or work, you don't need to know all of that. If she's within the town limits or within a certain group of friends, maybe that's okay if you don't know every detail. Maybe there are a few places outside the town that are "usual haunts" (mall, movie theater, whatever), and those are okay with you in general. So you don't really need to know which one she's at. Our deal was that our son was within the town (getting pizza, ice cream, whatever) or at one of a dozen or so houses that were the usual hangouts for the track team (ours was one of them, actually). Parents knew they would only have to call a few houses to find their kid in an emergency, and we all knew we were watching out for each other's kids - even if it meant we were in the kitchen whipping up platters of pasta and meatballs for kids who were watching movies in our basement without telling their parents exactly which home they were in.
If you need to know because of, say, making dinner, then you can say you'll assume she's taken care of unless you hear otherwise. She should be doing her own laundry and buying a lot of her own supplies even if you are picking up the tab. Maybe you can give her a budget and let her work on it - finding out the hard way how tough it is when she's out of money on the 20th and there's not more coming in until the 30th. That's a great life lesson and good preparation for being on her own!
Let her fall down a little without blasting her - she'll learn without you rubbing it in. We let our little kids take their first steps and trying pouring milk from the carton even though we knew it would end in disaster. But THEY had to experience the disaster themselves. Sure, we kept them from the really dangerous stuff like playing with the stove or running into traffic, but the moderate stuff is okay. I'd let your daughter know that you're not going to check every step of the way, and you trust her to figure it out. Let her know you're open if she needs help. Then push yourself to not track her phone all the time.
Now, if she heads to the city for a major rock concert or she's taking a highway trip or a weekend getaway, that's another story. But my son is 30 and lives elsewhere, and while he doesn't report in all the time by any means, he still shares a few photos from his weekend away and he absolutely sends me his flight or train itinerary if he's going to be in some other part of the country. I think that's because he realizes that there's a reasonable amount of worry, and an unreasonable amount.
I'd urge you to consider loosing the reins now, not because you have to, but because it's part of teaching her more skills by giving her more confidence and trust. If she screws up royally, you can always go back to something more structured "until she's mature enough to handle it."
And do give her an option of a code word or code text (something unique to your family) that she can use if she's in a rough situation and needs help or needs Mom to be the bad guy and extricate her from it. You don't want her afraid to come to you when stuff happens she couldn't foresee.
