Privacy
Starscroll works out its charts in your browser. It has no advertising and no analytics or tracking scripts. This page says what is kept when you use it, and how to remove it. Last updated November 2026.
Without an account
Nothing about you is kept on our servers. To set the chart’s angles and the planetary hours for where you are, the site asks our host, Cloudflare, for the approximate location of your internet address (a city, not a street). It is used for that page view and is not stored by us. Your browser remembers a few preferences (the dashboard’s arrangement, the chart style) in its own storage.
Your precise location is read only if you ask for it, through your browser’s own permission prompt, and is rounded to about a kilometre before it is used.
With an account
Sign-in is handled by Clerk, which keeps your email address and sign-in details. We keep, in a database at Cloudflare, what you save: your settings, your location if you set one, your birth date, time and place, and the names and birth details of any people you add for synastry. Please add other people’s details only with their agreement.
This is used only to show you your charts. It is not sold or shared with anyone else.
Other services
When you search for a place by name, the name you type is sent from your browser to Open-Meteo’s geocoding service, which, like any site you visit, sees your internet address. The site’s fonts and files are served from our own domain.
Removing your data
Settings has “Delete account”, which removes everything kept for you here and your sign-in at Clerk, at once. You can also remove your birth chart or a person on their own. Questions, or a request we handle for you: contact@starscroll.net.
