Not reliably. Dating apps keep profiles inside the app, and the main ones do not offer a search by name. What you can see depends on where you are, which filters you set and which settings she has chosen. A profile you cannot find does not mean she has none, and one you find does not tell you what it means.

If you are asking about someone you are dating, the better route is a short, honest question. The rest of this explains why.

Why you cannot just look her up

The big apps show you people through a feed, not a directory. You see profiles that fit your age range and distance, in an order the app picks. If she is outside your filters, paused, hidden or simply not shown to you that day, you will not see her.

So a search that finds nothing is not proof, and a feed that shows her is only proof that she had a profile at that moment. It does not say whether she is active, or whether it is an old one she forgot.

What people try

Browsing the feed in her area. If you set your location and age range to hers, you may come across her. It takes time and it is a poor test, for the reasons above.

Searching her name on the open web. Some people try this. The results are hit and miss, because a dating profile lives inside the app and a search engine mostly cannot see it.

Reverse image search. A photo search can show where a picture appears online. It will not reliably return a profile, because the apps keep their pages inside the app.

None of these gives a clean answer, and each one takes you further into checking on a person rather than talking to her.

What it would and would not prove

Say you found her. Think about what you have learned.

She might have made the profile before you met and never deleted it. She might be using it to keep an option open. She might have logged in once a month ago. A profile on its own says very little about what she wants from you.

Say you found nothing. She might use a different app, a different name, or a setting that keeps her out of your feed. You know nothing new.

Either way you walked away with a worry and no fact.

The better way to find out

If you are dating someone and want to know where things stand, ask. A short, calm line does more than hours of looking.

"Are you still on the apps? I'm not, and I'd like us to be on the same page."

"I've deleted mine. Are we both fine with that?"

A woman who is interested will answer plainly. A woman who dodges has also given you an answer. Either response tells you more than a screenshot would.

What if you are only curious about a friend or an ex

The same logic holds. A profile you find on someone who is no longer in your life is not your business, and checking it tends to make a man feel worse, not better.

If the person is a friend and you are concerned about their safety, say so to them directly. If it is an ex, the useful move is to put the energy into your own page and your own dates. Looking at hers will not change what comes next for you.

If you are the one being checked

It works in the other direction too. If you are on dating apps and a woman you are seeing might check, decide what you are comfortable with and say so early. Men who hide that they are still on the apps and get found out lose trust faster than men who said it themselves.

If you want to know how your own page looks to a stranger, hand your phone to a friend and ask what they would guess about you from it. It is the quickest honest read you can get.

What to do if the real worry is trust

Looking harder rarely settles a worry about trust. It usually adds to it, because every answer raises another question.

If you do not trust her enough to ask, that is the thing to look at. Ask her once, in person, and listen to how she answers. If the answer does not settle it, or you do not believe it, you have learned what you needed to know. You can then end it or accept it, and in both cases you are doing it as a man who dealt with her directly.
