Cookies & browser storage

Updated 3 October 2026. This page covers astrology.build and its licence account at app.astrology.build. The operator is identified in our legal notice.

Website preferences

The website does not set advertising or audience-tracking cookies. If you change the light/dark theme, your browser stores the preference in localStorage under theme. It stays on your device until you change it or clear the site's browser data. It is not a visitor identifier.

Desktop app preference and identifier

The desktop app stores your optional usage-sharing choice in local app settings. Only after you allow sharing does it generate a random installation identifier, replaced each UTC month. Turning sharing off deletes that identifier and stops new requests. This is app-local storage, not a website cookie; details and retention are in the privacy notice.

Account and security

The licence account uses necessary authentication and security cookies. These allow you to sign in, protect forms against forged requests and return to the page you requested.

• __Secure-authjs.session-token: signed-in session, up to 30 days, renewed with activity.
• __Host-authjs.csrf-token and __Secure-authjs.callback-url: request protection and sign-in return address; browser-session cookies.
• gloow-session: encrypted account context where used, up to 14 days.
• astrology_checkout_*: where the guest purchase flow is available, private access to that purchase's receipt, for 48 hours.

Security services may also set cookies when a browser challenge or abuse protection is required. They serve access and security purposes. Cookie names can have different security prefixes in a local test environment.

Payments and external services

Payment takes place on Stripe's hosted checkout. Stripe uses its own cookies and similar technologies to process payments, prevent fraud and, if selected, provide Link. See Stripe's cookie policy. Merely visiting our website does not load Stripe checkout.

Your choices

We do not ask for advertising-cookie consent because the website does not use advertising cookies. Necessary storage supports functions you request. You can delete or block cookies and local storage in your browser; blocking necessary cookies can prevent sign-in or receipt access. A purchase can still be recovered through the account using its purchase email.

For other personal-data processing and your rights, see our privacy notice.
