Privacy Policy

Coelestium collects as little about you as it can. This page explains what we keep and why.

What we collect

• Your email address, if you sign up for the newsletter or buy Premium. We use it to send the newsletter you chose, to sign you in to Premium and to contact you about your subscription.
• Subscription details: whether you have Premium, your plan and its renewal date. Stripe processes payments; your card details go to Stripe, never to us. Stripe’s own privacy policy covers what it keeps.
• A sign-in cookie that keeps you signed in to Premium on your device. We do not use advertising or tracking cookies.
• Basic server logs (such as IP address, browser type and the pages requested), kept by our hosting providers for security and to keep the site running.

What we do not do

• We do not sell or rent your information.
• We do not show ads or use advertising trackers.
• Our newsletters have no tracking pixels and no click tracking.

Who helps us run the site

We use a small number of service providers that handle data on our behalf: Render (hosting and database), Cloudflare (network and security), Resend (sending email) and Stripe (payments). They may only use it to provide their service to us.

How long we keep it

We keep your email while you are subscribed. If you unsubscribe or cancel, we keep a minimal record of that (so we do not email you again by mistake, and for tax and billing records as the law requires) and delete the rest on request.

Your choices

You can unsubscribe from any newsletter with the link at the bottom of it, and cancel Premium from Manage subscription. To see, correct or delete the information we hold about you, email coelestium.space@gmail.com.

Children

Coelestium is not directed at children under 13, and we do not knowingly collect their information.

Changes

If we change this policy in a way that matters, we will update the date above and tell subscribers by email.
