No. Tinder says the birth information you enter for Astrology Mode is private. It is used only to calculate your signs and is not shown to other users, so the women you are swiping on do not see your birth time or where you were born. Your date of birth is filled in from your sign-up and cannot be changed. If you leave out a detail such as your birth time, Tinder says your placement may come out less accurate.
What Tinder says happens to those details
Astrology Mode asks for more than most parts of the app. On top of the date of birth you gave at sign-up, it wants your place of birth and the time you were born.
Tinder's answer to the obvious worry is direct. That information is private. It is used only to calculate your signs, and other users do not see it.
So the details go in, the calculation comes out, and nobody scrolling past you gets your birth time or your hometown hospital. That is the whole of what Tinder says about it, and it is the part that answers the question.
Your date of birth is locked from sign-up
You do not type your date of birth into the mode. Tinder fills it in from your sign-up, and you cannot change it there.
That has one practical effect. Whatever date is on your account is the date the calculation uses. If you want the mode to reflect your real birthday, the date you signed up with has to be your real birthday. There is no separate box inside Astrology Mode to correct it.
It is also a good reason to be accurate at sign-up in the first place, because the mode gives you no way to fix the date later.
Leaving out your birth time
Plenty of men have no idea what time they were born, and the mode does not force you to find out. Tinder says leaving out details such as birth time may make your placement less accurate. In plain terms, the mode can still work out your signs, just with less precision.
Whether that matters depends on how much you care. If you enjoy astrology and want your signs worked out as precisely as possible, it is worth asking a parent or checking your birth certificate. If you are in the mode mainly for the fun of it, skip the time and move on. The women you meet will not be comparing notes on your placement accuracy.
What actually gives your privacy away
The worry behind this question is reasonable. Your birthday, your birthplace and the hour you were born are personal, and you would not hand them to a stranger in your first chat.
But the details you type into Astrology Mode are not where most men give too much away. The real leaks are on the page they choose to show. A photo in front of your building with the number visible. Your full name and your employer spelled out. A car with the license plate in frame.
Tinder keeps your astrology inputs private. Everything else on your page is your call, so give it the same scrutiny. Crop the street sign, blur the plate, and leave your exact workplace for a conversation in person.
What to share with her instead
If a woman asks your sign in the chat, tell her. It is small talk, and it can be a fun one. You do not need to hand over your birth time or your hometown to flirt about astrology.
If she wants your full chart, turn it into something playful rather than a data exchange. "You get my sign now. My birth time is a third-date secret" keeps a bit of mystery and gives her something to tease you about.
a dating coach's advice on the early part of any conversation fits here. Keep it light and fun, and point it toward meeting her. Swapping precise personal details in the first few messages does neither. And if anyone pushes hard for your exact birthday, birthplace and time before you have met, treat the pushing itself as a warning sign.
Is the mode worth using at all?
If astrology bores you, you lose nothing by skipping the mode. Your photos and your prompt answers do the real work either way.
If you enjoy it, the privacy design makes it low risk to try. Just keep your expectations in proportion. My point is that a woman does not care what you have in common until she already likes you, and a matching chart is still something in common. Shared signs can give you an easy first line. Her liking your photos is what gets you the chance to use it.
