Your details stay with you.

This free calculator processes birth details locally. It has no account system and does not ask for an email address.

What you enter

Your birth date, time, city, coordinates, selected time zone and any progression date live in the current page's memory. The calculator uses them to calculate a reading in your browser. We do not submit these details to a server, geocoding service, astrology API or generative AI service.

We do not put birth details or results in public URLs, cookies, local storage or analytics events. Refreshing or closing the page clears the application state. Your browser may independently restore form values or tab state according to your own browser settings.

The planetary hours tool also keeps your selected city, coordinates, time zone and date in page memory. Its Sun calculations run locally. It records only a calculation-completed event with a current-day or selected-date mode, and a calendar-download event. These events contain no location, date, planetary result or other form values.

The files your browser downloads

The browser downloads the site's pages, scripts, styles, locally served fonts and static place and ephemeris data. Juno and Venus calculations use the same ephemeris URL for every birth date, so we do not request a date-specific or decade-specific file. The progressed Moon calculator loads the same local lunar calculation module for everyone. Place searches run against a downloaded city list; the search text is not sent to GeoNames.

A hosting provider can process normal request information such as your IP address, requested resource, browser type and access time to serve the site. Those requests do not contain your birth details. Hosting infrastructure may retain access or security logs under the provider's own policies.

Cookies and tracking

When Vercel Web Analytics is enabled for this project, its script records page views and dimensions such as referrer, browser, device type, operating system and geolocation. Vercel says Web Analytics does not use third-party cookies; it identifies visits using a hash derived from the incoming request, with session data discarded after 24 hours. We do not send birth details or reading results as analytics events. This site does not display advertising or load advertising tracking pixels, and it does not request device location. You choose or enter your birthplace yourself. Read Vercel's Web Analytics privacy details.

Copying a reading

The Copy reading button writes the displayed Juno and Venus themes to your clipboard only when you click it. The copied text omits your date, birth time, city and coordinates. Anything you later share from your clipboard is your choice.

Saving planetary hours

The planetary hours Download calendar button creates an ICS file on your device. That file includes the selected location label, time zone and calculated times. It is not uploaded by this site. Importing or sharing it through a calendar app is your choice.

External sources

Links to NASA/JPL, GeoNames and other sources open external websites. Their own privacy practices apply when you visit them. Their data has been downloaded for this calculator; using the calculator does not send them a live request.

Changes to this tool

If a future version adds saved reports or payments, its data handling will need a corresponding update to this statement. This statement describes the free static calculator available now.
