Privacy Policy
Last updated 3 October 2026
In short. This website uses no cookies, no analytics and no trackers, and loads nothing from other sites. The only personal data it collects is the email address you give us if you join the early access waitlist, used only to tell you about early access. The Cosmo app has no server and no account: what you write goes from your Mac to the engine or provider you choose, never to us.
Who is responsible
This website (cosmo-agent.com) and the Cosmo app are run by Aldo Sula, who is the controller of the personal data described here. For any question about privacy, or to use your rights, write to hello@cosmo-agent.com.
This website
What we collect
Only what you choose to give us. The site sets no cookies and stores nothing in your browser. It has no analytics, no advertising and no social plugins. Every file, including the fonts, is served from cosmo-agent.com, so your browser does not contact any other site while you read it. The one form on the site is the early access waitlist, described below.
Early access waitlist
If you join the waitlist, we store your email address, the time you joined, and which version of the sign-up text you saw. We use your address only to email you about early access to Cosmo: when it opens, and what you need to know to take part. We do not share it, sell it, or use it for anything else.
The legal basis is your consent (Article 6(1)(a) GDPR). You can withdraw it at any time by writing to hello@cosmo-agent.com or by replying to any email we send, and we then delete your address. Otherwise we keep it until early access ends, then delete the list.
The list is kept in private storage at Vercel (Vercel Blob, in Frankfurt, Germany) that only we can read; Vercel acts as our processor. To keep bots out, the form has a hidden field and a minimum time to fill it in, and repeated attempts from one network address are briefly limited. Your IP address is used for that only in memory and is never stored with your entry.
Hosting
The site is hosted by Vercel Inc., which acts as our processor. To deliver the pages and keep the service secure, Vercel's servers handle technical data about each request, such as your IP address, the page requested, the time, and your browser's user agent, and may keep it in short-lived logs. We use this only to run and protect the site, which is our legitimate interest (Article 6(1)(f) GDPR). Vercel may process this data outside the European Economic Area under the safeguards of its Data Processing Addendum. See Vercel's privacy policy.
If you write to us, we receive your email address and your message and use them only to answer you. We keep them for as long as the conversation needs, then delete them. The legal basis is our legitimate interest in replying to you, or steps you ask us to take before an agreement (Article 6(1)(b) and (f) GDPR).
The Cosmo app
Cosmo is in development and not yet available. As it is designed:
- No Cosmo server, no Cosmo account. The app runs on your Mac and sends nothing to us.
- Your engines and providers. Claude Code sends your messages to Anthropic and Codex to OpenAI, exactly as they do in Terminal; an API provider you set up receives the conversations that use it. Their own terms and privacy policies apply. With a local model (Ollama or LM Studio), everything stays on your Mac.
- Logins and keys. Claude Code and Codex sign in with their own login; Cosmo never reads, stores or relays their tokens. API keys are kept in your login Keychain and sent only to the provider they belong to.
- Your data stays on your Mac. Chats, teams, tasks and workflows are saved as files in Application Support on your Mac, where you can delete them at any time.
Your rights
Under the GDPR you can ask to access, correct or delete personal data we hold about you, to restrict or object to its use, and to receive it in a portable form. In practice this concerns your waitlist entry, if you joined, and any emails you have sent us. Write to hello@cosmo-agent.com. You also have the right to lodge a complaint with a data protection supervisory authority, in particular in the country where you live or work.
Children
This site and the app are not directed at children under 16.
Changes
If this policy changes, the new version will be published on this page with a new date. A change that affects how your data is used will be stated clearly here.
