Privacy Policy
Last updated 2026-07-01. Mosaic is operated by Sourabh Nyalkalkar ("we", "us") as an independent developer. Questions about this policy: [email protected].
What Mosaic is
Mosaic is a pre-clinical intelligence tool over a curated biomedical knowledge graph (targets, compounds, patents, papers, clinical trials), used via a web app and an MCP (Model Context Protocol) server that AI clients like Claude can connect to. This policy covers both.
Information we collect
- Account information. Your email address (used for magic-link sign-in) and, if you provide one, a display name.
- Usage data. For each tool call (web app or MCP connector), we record the tool name, the target/entity queried, and a timestamp — used solely to enforce your plan's monthly quota and daily unique-target limit. We do not store the full request/response payload or your conversation with an AI client.
- Billing information. Handled entirely by our payment processor, Dodo Payments — we receive your subscription status and a customer/subscription reference, never your card details.
- Technical data. IP address and request metadata, retained briefly for rate limiting, abuse prevention, and debugging.
- Analytics (optional). Aggregate, non-identifying pageview and feature-usage events via PostHog, when enabled. This does not include your queries or tool-call content.
Connecting via Claude or another MCP client
When you add Mosaic as a connector in an AI client, that client sends tool-call requests (e.g. "look up target EGFR") directly to Mosaic's server on your behalf, authenticated by the sign-in you complete during connection. Mosaic sees only the parameters of each tool call, not your broader conversation with the AI client, and does not read or store the client's chat history, memory, or uploaded files.
How we use this information
- To authenticate you and maintain your session.
- To enforce plan quotas (free/Pro/Lab) and prevent abuse of the knowledge graph.
- To process subscription billing and send receipts.
- To send transactional email (sign-in links, billing notifications) — never marketing email without opt-in.
- To diagnose and fix bugs, and to improve the product.
We do not sell your personal information, and we do not use your queries to train any AI model.
Who we share data with
Mosaic uses the following service providers, each of which processes a limited slice of the data above solely to provide their service to us:
- Neon — database hosting (all application data).
- Railway — backend application hosting.
- Cloudflare — CDN, DNS, and edge security in front of getmosaic.dev.
- MailerSend — transactional email delivery (sign-in links, receipts).
- Dodo Payments — subscription billing.
- Anthropic — powers Mosaic's own agent/chat features (not the reverse — this is separate from you connecting Mosaic as a tool into Claude).
- PostHog — product analytics, when enabled.
We do not otherwise sell, rent, or share your personal information with third parties, except to comply with law or to protect Mosaic's or others' rights and safety.
Data retention
Account and usage-tracking data is retained for as long as your account is active, plus a limited period afterward for legal, billing, and fraud-prevention purposes. OAuth authorization codes expire within a minute of issuance; access tokens expire within an hour and refresh automatically. You can request deletion at any time (see below).
Your rights
Email [email protected] to request a copy of your data, ask us to correct it, or delete your account and associated personal data. We'll respond within a reasonable time, generally within 30 days.
Security
Passwords aren't used at all (sign-in is via time-limited, single-use email links); API/OAuth tokens are hashed at rest; traffic is encrypted in transit (TLS). See our security & vulnerability disclosure policy for how to report a security issue.
Not medical or clinical advice
Mosaic surfaces patterns in public pre-clinical literature and patent/trial data as a hypothesis-generation aid for research use. It is not medical, clinical, diagnostic, or investment advice, and nothing in the product should be relied on as such. This is a product disclaimer, not a data-privacy term, but we restate it here because it shapes what the service does and does not do with your inputs.
Children
Mosaic is not directed at, and is not knowingly used by, anyone under 18.
Changes to this policy
If we make material changes, we'll update the date at the top of this page and, where required, notify you by email.
