Most men never decide this. They answer whatever she asks, in the order she asks it, because refusing feels rude and because the conversation was going well.

Then a match goes strange, or a date falls through badly, and a person you have never met knows your surname, the name of the firm you work for, and roughly which building you sleep in.

None of that had to be in the app.

Section 01

Three levels that get treated as one

Personal information gets talked about as a single lump. It is really three things, and they cost you completely different amounts.

Your first name, your general part of town, and what you do in broad terms are ordinary conversation. Everybody shares them and almost nothing follows from it.

Your full name is different, because it is a search key. A first name plus a last name plus a city is enough to find your work profile, your old accounts, your family, and in a lot of cases a photograph of the front of your house. You are not giving her a name. You are giving her everything attached to the name.

Your employer is different again, because it is a place. A company name is somewhere a person can phone, email, or turn up to. The name is not the problem. The building it points at is.

Your address is a door. There is no version of that one that gets shared before you have met.

Section 02

What is fine to say before the date

Your first name. What you do, described the way you would describe it at a wedding. The part of town you live in, at the level of a district rather than a street. Your age, whether you have children, what you did at the weekend.

That is a real conversation. A man who will not say any of it is not being safe, he is being strange, and she will read it as hiding something rather than as good sense.

Section 03

What waits until after you have met

Your surname. The name of your employer. Your street, your building, or the bar you are in every Thursday. Your children's school. Anything with a number on it: your salary, your account, your door.

None of that makes the first drink better. All of it can be said on the second date, or the fifth, once you know who you are talking to.

Section 04

The parts you did not mean to send

Most of the leaking happens in photographs rather than in sentences.

A gym photo with the signage behind you names the gym, which names your neighbourhood and roughly your schedule. A work event photo in a branded shirt names the company. A shot taken on your own doorstep, with the number visible over your shoulder, gives away the exact thing you were careful about in the chat. A car in the background carries a plate.

Then there is the bio. Men write the firm's name in there because it reads like status. It is the fastest way to hand a stranger your whole working identity before she has typed a word.

And there is your phone number. Moving to another app feels like a small step, and usually it is, but a number is searchable, and the profile attached to it normally carries your photo and often your full name. That is fine when you have decided it is fine. It is worth knowing you decided it.

Section 05

Why men give it all away anyway

Because holding something back feels like an accusation.

She asks where you work. You pause. In your head that pause looks like you accusing her of something, so you fill it, and out comes the company name. That is the whole mechanism. It is not carelessness. It is politeness under mild pressure.

The fix is not to refuse. It is to answer the shape of the question instead of the specifics, warmly, with no speech about privacy attached.

Section 06

Answer the shape, not the detail

"What do you do?" becomes "I work in insurance, the boring end of it. Claims." Not the firm.

"Whereabouts do you live?" becomes "About ten minutes north of here." Not the street.

"What's your last name?" becomes "You'll get it on Thursday." That one is a joke and a boundary in the same six words, and it almost never lands badly.

None of those are refusals. You gave her something in every one. The rule is short enough to hold in your head at eleven at night: say the category, keep the identifier.

Section 07

She is doing exactly the same thing

If she gives you a first name only, keeps her workplace vague, and wants to meet somewhere busy, she is not cold and she is not playing a game. She is doing the version of this that women are told to do from about the age of fifteen, and her reasons are heavier than yours.

Reading it as suspicion of you personally is the mistake. Match her pace instead and it stops being a negotiation.

Section 08

After you have met, most of this goes away

None of this is permanent secrecy, and a man still withholding his surname in week four is the odd one now.

The point is sequence. Before you meet, she has a profile and a set of messages. After a drink, you both have an actual person to judge, which is the only information that ever mattered. Give it away in that order and you never have to think about any of this again.

Section 09

When you would rather not be running the account at all

There is a version of this where none of it is your decision at eleven at night, because the account is not being run by you.

Our team can rebuild your photos and your whole profile, then swipe and text on your behalf and keep running it until dates are on your calendar. The judgment calls in this article get made by people who have had the same conversation several thousand times, so the company name does not get typed into a chat to keep it warm. You turn up to the bar with her first name and find out the rest of it at the table, which is where it used to happen anyway.
