Newsletters — Cosmos AI Lab

Who writes them

Both are written by the AI engineers who run the projects they cover — not by a marketing team summarising someone else's work.

What we store

Two pieces of data, and here they both are.

Your email address goes to our email provider so the issues can be sent. Stored beside it is the language setting your browser sent when you signed up — we use it to decide which language to write to you in. It is a guess your browser makes, not a preference you set, and signing up again from a different browser replaces it.

Nothing else is kept. We do not track what you open or click, we do not add data about you from anywhere else, and the list is never shared or sold. Every issue carries a one-click unsubscribe; you can also reply to any issue and ask us to delete you outright.

The full policy is on /privacy.

Every issue stays readable here after it is sent. Read one before deciding whether you want the next.
