Celestia Privacy Policy

Celestia is made by Twixalot Software Solutions. The responsible party for this app is:

• Keita Smith, Twixalot
• Krummackerstrasse 4, 8902 Urdorf, Zurich, Switzerland
• Email: keita.smith@twixalot.com
• Phone: +41 76 324 51 00

A birth chart is worked out from the date, time and place of birth, so Celestia asks for them. It uses:

• Birth details you enter: a name or nickname, the date of birth, the time of birth if you know it, and the place (its name, coordinates and time zone). The same for anyone you add in Match.
• Your email address, only if you choose to add one to keep your details in an account.
• A random sign-in id made for your phone, so only Celestia can use its calculation service.
• Technical data that any server receives with a request, such as the IP address and the time of the request.

Celestia does not ask for your contacts, location, photos or advertising identifier.

Your birth details, the people you add in Match and the latest results are kept in Celestia’s own private folder on your phone. The results are kept so the app still works without a connection.

To work out a chart, the birth details are sent over an encrypted connection to Celestia’s calculation service, inside the request and never in the web address, so they don’t end up in logs. The service works out the answer and sends it back. It doesn’t store the birth details.

When you search for a birthplace, the search is sent the same way and looked up on our own server, not passed to a mapping company.

Each request carries a sign-in. Until you add an email, that sign-in is a random id made for your phone, with no name, email or birth details in it.

If you add your email in Settings, under Account, your birth details and the people you’ve added are also kept in your account, so you can sign in on another phone and find them. You sign in with a one-time code sent to your email; there is no password.

Only you can read what is kept in your account. Without an email, nothing is kept anywhere but your phone.

• No advertising.
• No analytics and no tracking.
• No selling or sharing of your data for marketing.

Celestia uses a small number of providers to run:

• Supabase, for the sign-in and the optional account.
• A hosting provider for the calculation service.
• An email provider, to send sign-in codes.
• Apple and Google, who distribute the app through their stores under their own privacy policies.

Some providers may process data outside Switzerland, for example in the EU or the United States. Where required, appropriate safeguards are used.

On your phone, until you delete it. In your account, until you delete the account. When you delete your account, your email and everything kept in it are removed from our database straight away; copies in routine backups are overwritten after a short period.

• See everything kept in your account: Settings, then Account, then Export my data.
• Without an account, delete everything on your phone: Settings, then Delete my data on this phone.
• Delete your account and everything in it: Settings, then Account, then Delete my account.

You may also ask for information, correction or deletion of your data, where the law allows, by writing to keita.smith@twixalot.com.

Celestia is not directed at children. If you think a child has entered their details, write to keita.smith@twixalot.com and we’ll delete them.

This policy will be updated when Celestia changes, for example when subscriptions are added. The date at the top shows the latest version.
