You can share a birth chart in three steps. Decide who should see it. Remove the details they do not need. Get permission before you post anyone else's chart. This guide explains each step, with a checklist you can use before every share.
A birth chart is a map of the sky at the moment someone was born, as described in this orientation guide. It is built from a date, a time and a place. Those three details are personal data. Treat them that way.
TL;DR
- Share your own chart first. Ask before you share or interpret anyone else's.
- Share only what the conversation needs. A chart image does not need a full birth date, a birth city and a name.
- State whether your birth time is exact, approximate or unknown.
- Check the audience setting of every platform or group before you post.
- Use sharing tools that let you delete a chart and control who sees it.

What you are actually sharing
A chart image looks harmless. It is a wheel with symbols. But the wheel is calculated from your birth date, birth time and birth place. Anyone who knows how to read one can work backward toward those details. Some chart images print them in the corner.
Before you share, look at what the file shows. Check for:
- Your full name
- Your full birth date
- Your birth time to the minute
- Your birth city or town
- A username or watermark that links to your other accounts
A birth date is also a common piece of personal data used to verify identity. Consumer Action's guide to social media privacy lists your birthdate among details to think twice about posting. A chart with a full date and place gives the same information in a different form.
Decide who the audience is
Different audiences need different amounts of detail. Pick one before you export anything.
| Audience | What to share | What to leave out |
|---|---|---|
| Close friend or partner, one on one | Full chart, if you want a deep reading | Nothing, if you trust them and they trust you |
| Small friend circle | Chart image, Sun, Moon and Rising signs | Exact birth time and birth city |
| Private community group | Chart image with placements only | Full name, full date, birth place |
| Public post | Single placements or a cropped image | Anything that identifies you or someone else |
This is a practical rule, not a law. You decide where your line is. The point is to decide before you post, not after.
Share your own chart first
Start with yourself. Your own chart is yours to share. When you post it, you choose the risk.
A chart from someone else is different. It belongs to them. Astrology University's ethics guidance says consent matters before a reading and during it. If a sensitive topic comes up, ask the person if they want to explore it. Do not present your interpretation as a fact.
This applies most to:
- Partners and exes
- Children
- Clients or people you read for
- People you mention in public community posts
Do not use a partner's chart to claim you know what they think or why they act a certain way. A chart is a starting point for a conversation. It is not private access to another person.
Ask before you share someone else's chart
Use a short message. Keep it plain.
- Say what you want to share. "I want to post our charts side by side."
- Say where. "In a private group of about 20 people."
- Say what will be visible. "Signs only, no birth date or city."
- Say they can refuse. "Tell me if you would rather I do not."
- Respect the answer.
If they say no, do not share. If they say yes for one place, do not move it to another place without asking again.
Removing a name does not always make a chart anonymous. Professional ethics guidance treats birth data, charts and recognizable stories as confidential. In a small community, details like a job, a city or a family story can point to one person. If someone could guess who it is, ask first.
State how reliable your birth time is
An accurate chart needs an accurate birth time. The Federation of Australian Astrologers' code says members should consider the reliability of birth data and tell clients about the limits that come with it. That is a professional code for practicing astrologers, but the idea works for any shared post.
Add one line to your post:
- Exact: "Birth time from my birth certificate."
- Approximate: "Birth time is about 3 PM, give or take an hour."
- Unknown: "No birth time. Rising sign and houses are not shown."
This helps readers. The Rising sign and house placements change with the birth time. If the time is a guess, people interpreting your chart should know. It also stops arguments over "wrong" readings that come from bad data.
Check the platform before you post
Each platform has its own audience settings. Check them every time you share a chart.
The Federal Trade Commission's September 2024 staff report found that large social media and video streaming companies collected and could indefinitely retain large amounts of user data. The report looked at major platforms, not astrology apps. But the lesson carries over. A post you delete from view may still exist in a company's systems. Share less in the first place.
Use this checklist:
- Audience. Is the post public, friends only, or a private group? Check the setting on this post, not your default.
- Group size. A private group of 5,000 is not private in practice.
- Downloads. Can others save or screenshot the image? Assume yes.
- Location. Turn off location tagging on the post.
- Edits. Can you delete or edit the post later? Find out where the button is before you need it.
- Account link. Does your profile show your real name, city or birthday? Those can be matched to your chart.

Share a chart image or share the data
There are two ways to share a chart. They carry different risk.
A chart image is a picture. It shows the wheel and the placements. It is easy to post. It is also easy to copy and repost.
Birth data is the date, time and place. With it, anyone can generate your chart again, in any system. Share raw birth data only with people you trust, and only when they need it. A friend who wants to run your synastry needs the data. A group thread does not.
A good middle path: share the image with placements as text. For example, "Sun in Pisces, Moon in Virgo, Rising in Leo." That gives enough for a conversation and no data to recalculate from.
Share charts for synastry
Synastry compares two charts to look at how the placements of two people relate. It needs data from both people. That raises the consent question twice.
Follow this order:
- Share your own chart first.
- Ask the other person if they want to share theirs.
- Agree on who will see the comparison.
- Agree on what happens to the data after.
- Read the results together, and treat them as prompts for talk.
If you want to learn the method, read our explainer on what synastry astrology is and how to read it. If you use AI for it, see the math and limits of AI synastry readings so you know what the output can and cannot tell you. You can also compare birth charts with Tarosyn AI to see the top contact points between two charts.
Do not run a synastry on someone who has not agreed. It may feel harmless. But it uses their birth data without their say.
Share in a community
Sharing a chart in a community can be good. People find others with the same placements. They learn from each other. We wrote about how astrology creates shared identity and why this feels meaningful to many people.
To keep it good:
- Read the group rules first.
- Ask who can see posts and who can join.
- Post placements, not raw birth data.
- Do not post other people's charts.
- Do not ask others to share their birth data in comments.
- Report posts that expose someone's data.
The FTC report also explains a common mistake: users may assume that a private group means limited downstream use of their data. A private group limits who sees the post. It may not limit what the platform does with it. Read the privacy policy of the service that hosts the group.
Sharing a chart without giving a reading
You can share a chart and let people read it. You can also share it and add your own reading. Keep these separate.
When you add a reading to your own chart, that is your view of yourself. Say so. Use first person. "My Moon in Virgo makes me notice details." Do not write "Virgo Moons are always anxious."
When you comment on another person's chart, ask. A reading can land hard. A birth chart can name a pattern someone has felt for years, and that moment can be strong. Let the person set the pace. If they do not want to go into a topic, stop.
If you want to read your own chart before you share it, our birth chart self-analysis guide shows you how. If you are new to charts, start with how a birth chart works.
Before you share: a final checklist
Run this list each time.
- Is this my chart, or someone else's?
- If someone else's, did they say yes, for this place?
- Who is the audience?
- Does the image show a full name, date, time or place?
- Have I stated if the birth time is exact, approximate or unknown?
- Is location tagging off?
- Do I know how to delete this post?
- Would I be comfortable if this chart was seen by someone I do not know?
If any answer is no, stop and fix it.
Our perspective
We build Tarosyn around one idea: your chart is personal first and social second. We think sharing should be a choice you make each time, not a default.
Tarosyn is an AI-powered app for tarot, astrology and numerology, with a social community. Because we offer community features, we think about this question often. People want to connect over their charts. They also want to keep their birth data under their control. Both are fair. A good tool supports both.
Our approach is privacy by design. That means the settings that protect you should be easy to find and easy to use. It also means you can keep your practice personal, or connect with friends and a community when you want to. We see these as two modes of the same practice, and you can switch between them.
We also think AI readings should work from your own context. Tarosyn readings remember your history and use your birth chart as context. That memory is useful. It is also why you should know what is stored. Read how we think about it in our posts on birth chart privacy and indefinite retention.
Our advice is simple. Share your chart because you want to talk about it, not because a platform asks you to. Share less than you think you need. Ask others before you share theirs. If a tool makes any of those hard, use a different tool.

FAQ
Is it safe to share my birth chart online?
It can be, if you control what it shows. Share the wheel and placements, not your full birth date, birth time and birth city together. Choose the smallest audience that fits your goal. Once an image is public, you cannot control who copies it.
Can I share my partner's birth chart?
Only with their permission. Ask what they are comfortable with and where. Ethics guidance for astrologers treats charts and birth data as confidential. A yes for a private chat is not a yes for a public post.
What should I include when I post my chart for others to read?
Include the chart image, the placements you want discussed, and a note on your birth time. Say if it is exact, approximate or unknown. Leave out your full name, full date and birth place unless the reader needs them.
Does removing a name make a chart anonymous?
Not always. In a small group, a job, a city or a story can identify a person even without a name. Professional guidance warns that removing a name may not be enough. If someone could guess who it is, ask first.
How do I share a chart for a synastry reading?
Share your own chart first. Then ask the other person if they want to share theirs. Agree on who sees the result. Treat the reading as a prompt for a conversation, not as a verdict on the relationship.
