Inviting your partner: compatibility calculated together

Why invite rather than guess

A compatibility is read between two whole charts: the Suns, but above all the Moons, Venus, Mars and the Ascendants. Yet the Ascendant changes sign about every two hours, and the Moon every two and a half days. With an approximate time for the other person, part of the reading rests on a guess.

The invitation settles the matter simply: each person enters their own birth details, the ones they know best. You have nothing to ask out loud, and no time dictated over the phone to remember. And the discovery is shared, which is often the nicest part.

Creating and sending the link

The “Invite my partner” button is found in three places: in the tools of your chart page, on the synastry page and below the compatibility form. It uses a chart calculated on your device: if there is none, calculate your chart first.

1. Tap “Invite my partner”: a panel opens and tells you what the link contains.
2. If your chart has no first name, add yours: your partner will know who is inviting them.
3. Tap “Send the invitation” to open your phone’s share sheet (messages, messaging apps, email), or “Copy the link” to paste it wherever you like.
4. Your partner opens the link, enters their date, time and place of birth, and lands on your compatibility.

What the invited person sees

The invitation page is plain: “Camille invites you to compare your charts”, your first name, your Sun sign, and a form for their own birth details. Your date, time and place of birth do not appear there.

Once their birth details are entered, your partner lands on your compatibility page, the same one as if you had filled in both sets of details yourself: the scores, the reading for two, the two wheels. That page shows both sets of birth details, theirs and yours. A button offers to send the result back to you, so that you can read it in turn.

The invitation requires no account, neither from you nor from your partner. To keep both charts and their reading, a free account is enough afterwards.

What the link contains, exactly

On My Birth Chart, a free chart lives in its address: nothing about your birth is recorded on our servers. The invitation link follows the same rule. It carries your date, time and place of birth, and your first name if there is one; that is what makes it possible to calculate your chart when your partner opens it.

The panel tells you so before sending, so that you choose who receives it. Anyone who gets this link can calculate your chart: send it to your partner, not to a group chat. The details of what the site keeps, or does not keep, are in the privacy policy.

• No account and no email address are attached to the link.
• Nothing is kept on our servers: the link is the only place where your birth details are found.
• The invitation page is not listed by search engines.

Two exact births, two simple steps

The accuracy of the result depends on both sets of birth details. On your side, check your time on your birth certificate: the “round” time remembered in the family is sometimes half an hour off. On your partner’s side, the form accepts an unknown time: the compatibility is then calculated without their Ascendant, and the page says so.

The place matters too: it sets the time zone and the Ascendant. The form suggests the town from the first letters; for a birth abroad, choose the city from the suggested list. The birth time page explains what each of these details changes in a chart.

After the result

The calculated compatibility reads like any other: the love compatibility page explains the scores, the contacts between your planets and the reading for two. You can also share the reading just as you read it.

Want to compare with someone else? The invitation link can be used again: it does not wear out and keeps nothing about the person who opened it. Each opening gives a new calculation, from the birth details entered that day.
