Terms of use

What Lizastro is

Lizastro computes a natal chart from your birth data, writes a reading from that chart with an AI model, and lets you form rooms (Circle) with friends and family where you share parts of your chart.

Some calculators are free to use without an account. Their birth details are computed on the server and are not stored.

Your account

You sign in with an email address or a Google account. You are responsible for what happens under your account and for keeping the sign-in link or password to yourself.

Sign-up does not check your age. This draft sets no minimum age; whether one is needed is an open question for legal review.

Give birth data that is true to the best of your knowledge. A wrong birth time or place produces a wrong chart, and the chart says when the time is unknown.

Astrology is interpretation, not advice

Positions are computed astronomically. What they are said to mean is interpretation, not fact. Nothing in Lizastro is medical, financial or legal advice, and it should not decide any of those for you.

AI-generated text can be wrong

Readings and answers are produced by an AI model working from your chart data. They can be inaccurate, repetitive or badly worded. The contacts a reading is built from are listed under it, so you can check the claim against the numbers.

Your content and Circle

What you enter stays yours: your birth data, the people you add, your life events, your questions. We use it only to run the features you use.

In a Circle, each member sets their own share level. Raw birth data is never shared; the level decides how much of the computed chart others see. Only you can change your level. Do not add another person's birth data unless you are entitled to.

Acceptable use

Do not try to get into other people's accounts or data, to overload or probe the service, to get around the rate limits on the free tools, or to use Lizastro to harass or deceive someone.

We may limit or close an account that does this.

Payments

There are no payments today. Nothing in Lizastro is sold and no card details are taken. If paid plans are introduced, these terms will be updated before they start.

Export and deleting your account

You can request an export of your data and delete your account from the account menu in the app. Deleting removes your birth data, chart, conversations, reports and Circle memberships. Circle rooms you created are deleted for everyone in them.

Changes and availability

Features can change, move or be removed, and the service can be unavailable for maintenance or because of a fault. Nothing here promises uninterrupted service. When these terms change, the date at the top of this page changes with them.

Third parties

Planet positions are computed with the Swiss Ephemeris, made by Astrodienst.

Readings and reports are written by an AI provider; at the moment that is DeepSeek, a China-based company. Only structured chart data and what you type into Ask AI reaches it.

The database is Supabase and the application runs on Vercel.
