Our Birth Data Promise
A birth chart starts with the most personal facts you have: where you were born, and exactly when. Here is what we do with them — and what we will never do.
We never sell your data.
Not to advertisers, not to data brokers, not to anyone. There are no ads here and no ad trackers. Our only revenue is the subscription prices you can see for yourself.
We never train AI models on your data.
Your chart, your conversations, and the memories the AI keeps for you exist to write your readings, nothing else. The AI providers that help write them work under business terms that do not permit them to train on your data either.*
Your chart is computed on our own servers.
Planetary positions come from our own Swiss Ephemeris engine — the same calculation standard professional astrologers use, cross-checked against NASA's ephemeris. Looking up your birthplace sends only the city and country you typed; your name and birth date stay home. On the rare day our engine can't compute a chart, a specialist calculation service is the backup — our Privacy Policy names it and exactly what it receives.
Nothing is shared unless you share it.
Everything you make here is private by default. Each chart's public link is an unguessable address that only you can reveal; we show you exactly what it exposes before your first share, and you can switch any link off. Friends see only the chart you chose to share — never your readings, your conversations, or your memories — and deeper chart detail stays off until you turn it on, friend by friend, reversibly.
You can see it, take it, and delete it.
My Data shows everything the AI remembers about you, and you can delete any of it. Your readings can be printed or downloaded. Delete Account permanently erases your account and its data from our database — and we spell out the narrow exceptions instead of hiding them.
Your data has one job.
We are a small, independent astrology app. Your birth data is here to make your readings better, and that is the only thing it will ever be for. If our data practices ever materially change, we will tell you by email before the change, not after.
Who else ever sees anything
The complete list of services that help run the app, and exactly what each one receives. Each link goes to the full detail in our Privacy Policy.
- Google sign-in — signs you in; in return we receive your name, email address, and profile picture.
- Site analytics — Google Analytics collects aggregate usage stats, like which pages are popular. You can opt out.
- Our AI provider — receives the inputs to your readings: your name, birth details, chart positions, chats, and memories.
- The birthplace geocoder — receives only the city and country text you typed. Never your name or birth date.
- Stripe — handles payments if you subscribe. It receives your payment details directly; we never see card numbers.
- Our email provider — is used only if you turn on transit or digest emails (off by default) and receives your email address and the message content.
- Our host (Render) — runs the app and stores the database, encrypted in transit and at rest.
- The backup chart calculator — a rare fallback that receives birth details only when our own engine can't compute a chart.
