Privacy
How Cosmic Stack handles data on this website and across our products. Local-first by default; minimum-necessary collection; clear retention windows.
What this page covers
This policy applies to the marketing website at cosmicstack.ai. Each product we ship (Mercury Agent, Sav.ink, Cosmic Stack Cloud) has — or will have — a separate, product-specific privacy notice that supersedes this one for that product's data flows. Where those notices exist, they are linked from the product page.
What we collect on this website
- Server access logs. Standard request metadata (IP address, user agent, path, status code) is logged at the edge by Cloudflare for security, debugging, and abuse prevention. Retained for 30 days.
- Contact form submissions. When you email us through a form on this site, we store the email and message in our transactional email provider for as long as needed to respond. You can request deletion at any time.
- Aggregated, privacy-preserving analytics. We use a cookieless analytics provider that records anonymous, aggregated page views. No fingerprints, no cross-site tracking, no advertising identifiers.
What we don't do
- We do not sell data. Not to anyone, not under any condition.
- We do not run third-party ad pixels or marketing trackers.
- We do not use dark patterns to obtain consent for things you wouldn't agree to in plain English.
- We do not train models on customer data without explicit, specific, opt-in consent.
Cookies
This website uses no cookies for tracking, marketing, or personalization. The only client-side state we set is an ephemeral preference (e.g. reduced-motion override) stored in localStorage and never transmitted to our servers.
Your rights
Wherever you are in the world, you can email hello@cosmicstack.ai and ask us to (a) tell you what data we hold about you, (b) delete it, (c) correct it, or (d) export it in a portable format. We will respond within 30 days.
Changes to this policy
We will note material changes here and update the "Last updated" date at the top. Substantive product changes that affect data handling will be communicated by email to affected customers.
