Privacy Policy
Summary
Zodivio does not require an account. The preferences you choose — your zodiac sign, an optional birthday used to find your sign, and your language — are stored only on your device (in browser storage on the web, or app storage on iOS and Android). Birth charts you save stay on your device too, unless you choose to sign in to sync them across your devices. You can delete them at any time.
Birth chart data
To create a birth chart you enter a date of birth and, optionally, a birth time and birthplace (city name, coordinates and its time zone). We ask only for what the calculation needs: no name, email or account.
Charts are calculated on your device. Drafts, and the charts you save while signed out, are stored only on your device; we do not keep a copy of them.
Images you share or download show your signs and chart only. Your birth date, time and place are added to an image only if you tick the option to include them.
Optional account and sync
You can choose to sign in from the My Saved Charts screen with your email address and a one-time code. Creating and reading charts never requires an account.
While you are signed in, the charts you save — label, birth date, time, birthplace (city name, coordinates and time zone), house system and the resulting Sun, Moon and Rising signs — are stored in your account so they sync across your devices. When you sign in, we also offer to upload the charts already saved on that device; nothing is uploaded unless you choose to.
Your account holds your email address, sign-in timestamps and the random install identifiers of the devices you signed in from (used only to apply a Premium subscription on all your devices). Accounts and charts are stored with our database and authentication provider, Supabase, and every stored chart can be read or changed only by your own signed-in account.
Signing out keeps your account; charts in it are no longer shown on that device until you sign in again.
AI interpretations
When you open the detailed reading, your app sends the birth date, time, coordinates and time zone to our server, which recalculates the chart to choose the in-depth texts that apply to it. Nothing is sent to an AI provider for this, and the details are not stored or logged.
When you request an AI reading, a personal synthesis of an area of life, a personal forecast or a compatibility report, or use the AI chat, your app sends the birth date, time, coordinates and time zone to our server, which recalculates the chart. Our server then sends only the calculated planetary positions, houses and aspects (plus your chat messages, for the chat) to our AI provider, Anthropic, to write the text. Your birth date, birthplace and any identifier are not sent to the AI provider.
Our server keeps generated readings in temporary memory, keyed by a one-way hash of the chart, so the same reading is not generated twice. It does not write birth details to logs or to a database. Readings are also cached on your device so they do not need to be requested again.
A compatibility report compares two saved charts, so it also sends the second person’s birth date, time, coordinates and time zone to our server, handled exactly like your own. Only add another person’s birth details with their permission.
Astrology readings are for reflection and entertainment. They are not scientific predictions or professional advice.
Premium subscriptions
If you subscribe, the purchase is handled by the App Store, Google Play or our payment provider; we never see your card details. To check whether a subscription is active, the app sends a random install identifier (not linked to your name or birth data) to our server, which asks the payment provider. If you are signed in, the app also sends your account sign-in token, so a subscription bought on one of your devices is honoured on the others.
Deleting your data
You can delete a saved chart at any time, or delete all birth chart data — saved charts, drafts and cached readings — from the My Saved Charts screen. When you are signed in, “Delete all my birth chart data” also deletes every chart stored in your account. Clearing site data or uninstalling the app removes everything stored on your device.
To delete your account, sign in and choose “Delete my account” on the My Saved Charts screen. This permanently deletes your email address, your linked install identifiers and every chart stored in your account. Charts saved only on that device are kept until you delete them. You can also email us to request deletion.
Your rights (GDPR and similar laws)
We process birth details on the basis of your request for the service (to provide the chart or reading you asked for). Wherever you live, you can ask us to access, correct or erase personal data, to restrict or object to processing, or for a copy of your data, and you can complain to your local data-protection authority. If you do not use an account, we do not store your birth details on our servers and most requests can be fulfilled on your device directly. If you use an account, you can view, correct and delete your synced charts in the app, and delete the account itself at any time.
Our hosting, database and AI providers may process data outside your country. We rely on their contractual safeguards, such as Standard Contractual Clauses, for international transfers.
Information we process
Like most websites, our hosting provider may process technical information such as your IP address, browser type and the pages you request in order to deliver the site securely and to limit abuse. We do not sell personal information.
If you email us, we use your message and email address only to reply to you.
Notifications
Zodivio does not send push notifications today. If we add optional daily reminders, we will only ask for permission when you choose to turn them on.
Children
Zodivio is intended for a general audience and is not directed at children under 13.
