Privacy

Your birth details stay on your device.

That is the whole design, stated in one sentence: your birth details are calculated and saved on your own device; we never ask for an account or an email, and we hold no copy. The rest of this page is the detail standing behind that sentence.

What we do not collect

We built SignWheel to work without collecting your birth details.

No accounts and no passwords. No email address is needed to calculate, view, save, or share a chart. Birth dates, birth times, and birth places you enter are not stored in a database by us, are not added to any advertising profile, and are not sold or rented to anyone. The calculation itself happens in your browser, on your device, so the details you type do not need to travel to us at all.

What is stored, and where

On your device. Charts you choose to save are stored in your browser's local storage on your device, so you can come back to them. They stay there until you delete them on the chart page, clear your browser storage, or your browser removes them. We cannot see, recover, or delete a chart stored only on your device. If you change devices or browsers, your saved charts do not follow you. On a shared or public computer, delete your saved charts before you leave, the same way you would sign out of any other site.

On servers. Like any website, when a page is loaded, hosting and security providers record standard technical logs, such as IP address, browser type, the page requested, and the time of the request, to run the site, prevent abuse, and fix faults. Our pages and share links are designed so that birth details are not written into these logs: a share link keeps its chart details in the part of the address after the #, which browsers do not send to servers.

Contact. This first version of SignWheel has no inbox and no contact form, by the same design: we do not want your details. If a contact route opens, it will be named on this page before it opens.

Cookies, advertising, and visit counting

This version of SignWheel sets no advertising cookies, runs no advertising, and uses no visit-counting service. If that changes, this page changes first, in plain words, before the change takes effect, and any advertising cookies will be described here with a real way to refuse them. Your birth details are never put in cookies by us and are never sent to advertisers by us.

Sharing a chart with another person

Some results can be shared as a link. Please read this before you share one.

A share link contains the chart details needed to rebuild the chart, such as birth date, birth time, and birth place. It does not need a name, and we recommend you do not add one. Anyone who has the link can open it and see those details. Treat a chart link the way you would treat the birth details themselves, and only send it to people you are happy to see them. Links you share may pass through other services, such as messaging apps, which have their own privacy rules.

If you enter another person's birth details to make a chart, please only do so with details that person is happy for you to use, and delete the saved chart from your device if they ask you to.

Your rights

Depending on where you live, you may have rights to know what personal data an organisation holds about you, to correct it, to delete it, to limit or object to its use, and to complain to your local data protection authority. Because your saved charts are held on your own device, you can delete them yourself at any time. This version of the site holds nothing else about you: the only data a website inevitably touches is short-lived technical logs, which carry no birth details.

Residents of California: we do not sell personal information for money, and this version of the site shares none for advertising.

Children

SignWheel is made for adults, and for older teenagers where their local law allows them to use a service like this with a parent or guardian's permission. We do not knowingly collect personal data from children under 13, and we do not run accounts for children.

Changes to this policy

If we change how the site handles data, we will update this page, change the date below, and, where the change is significant, say so clearly on the site before the change takes effect. A future optional feature, such as email delivery or synced charts, will have its own section here and its own separate opt-in. It will not be switched on for existing saved charts.

Last updated: November 2026 (pre-launch draft build; this policy will be reviewed before the site opens to the public).
