Terms
Cosmos is research-stage software operated by Polarity Lab (Providence, RI). By signing in or connecting a client to cosmos.polarity-lab.com you agree to the terms below. If you do not agree, do not use the service.
What cosmos does
Cosmos stores a personal knowledge graph for you. Nodes and edges are written by you directly, by clients you authorize through MCP keys, by local iMessage sync when you run it on your own Mac, and by cosmos itself when it extracts observations. You can read, export, and delete that graph at any time.
The account
You sign in with an email or Apple ID. The account is yours. MCP keys you mint are long-lived bearer tokens, so treat them like passwords. You can revoke any key from connectors at any time.
What you write into cosmos
You own everything you write. Polarity Lab does not claim ownership of your graph. Cosmos uses your graph to operate the product for you. We do not sell your graph and we do not feed it into third-party training corpora.
Research use
You allow Polarity Lab to use aggregated or de-identified high-level patterns to understand how people use cosmos. That research right does not give us ownership of your graph, and it does not let us publish identifiable private contents without your explicit consent.
What cosmos writes back
Cosmos extracts observations from your conversations and from authorized client activity. These observations are visible to you. They are not shared with other users.
What we cannot promise
- Uptime. Cosmos is research-stage. Outages happen.
- Bug-for-bug data fidelity. Schemas and extraction may change. Your graph survives, but views may shift.
- Model quality. Reasoners we route through are external. Their behavior is their own.
- Permanence. We may discontinue the service with reasonable notice and an export window.
What is forbidden
- Using cosmos to store data about people who have not consented.
- Building automated abuse of the chat or MCP endpoints.
- Reverse-engineering or copying the service for a competing product. Patents are pending.
- Using cosmos for unlawful activity under US or Rhode Island law.
Termination
You can delete your account by contacting [email protected]. We retain backups for 30 days and then purge. We may terminate accounts that violate these terms or that we are required to terminate by law.
Liability
Cosmos is provided as is without warranty. Polarity Lab's total liability for any claim arising from your use of cosmos is limited to the fees you have paid us in the prior twelve months, which today is zero.
Changes
We may update these terms. Material changes are surfaced in-product before they take effect.
