Privacy Policy

Last updated: June 2, 2026

This policy explains how Nodea (“Nodea,” “we,” “us”) handles your data across both the Nodea web app at nodea.ai and the “Nodea Tree for Claude” browser extension.

The browser extension

The “Nodea Tree for Claude” extension reads the branch structure of conversations you already have on claude.ai and draws them as a visual tree inside the page. It does this using your existing, logged-in Claude session — we never ask for, see, or store your Claude credentials.

What the extension accesses

  • Your Claude conversation content (messages, branch structure, message IDs) — read from Claude’s own API in your browser, solely to render the tree and to power the “Open in Nodea” and “Update Conversation” features.
  • Per-conversation display preferences (such as node colors), stored locally in your browser via chrome.storage.

What is transmitted, and when

  • Reading / visualizing the tree: conversation data stays in your browser. Nothing is sent to Nodea’s servers.
  • Only when you click “Open in Nodea” (or “Update Conversation”): the conversation tree you chose is sent to your authenticated Nodea account so it can be rebuilt as a Nodea conversation. This happens only on your explicit action, never automatically.

What we do NOT do

  • We do not sell or rent your data.
  • We do not use your data for advertising.
  • We do not transfer your data to third parties except as needed to provide the service (see “Service providers” below).
  • We do not collect data from any site other than claude.ai and nodea.ai.
  • We do not access your Claude data unless you have the extension installed and are using it.

The Nodea web app

When you create a Nodea account, we store your email address (for authentication) and the conversations you create or import. Chat messages you send are processed by our AI provider to generate responses. We use this data only to operate the product — show you your conversations, generate replies, and manage your plan and usage.

Service providers

We rely on the following processors to run Nodea:

  • Supabase — authentication and database (stores your account and conversations).
  • Anthropic — the Claude AI models that generate replies.
  • Stripe — payment processing for paid plans (we never see your full card details).
  • Vercel — application hosting.

Data retention & deletion

Your conversations are kept until you delete them or close your account. To delete your account and associated data, email us at the address below and we will remove it.

Limited Use disclosure

The “Nodea Tree for Claude” extension’s use of information received from Claude/claude.ai adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. Conversation data is used only to provide and improve the user-facing tree-visualization and import features described above; it is not transferred or used for any other purpose.

Not affiliated with Anthropic

Nodea and the “Nodea Tree for Claude” extension are not affiliated with, endorsed by, or sponsored by Anthropic. “Claude” is a trademark of Anthropic, PBC.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the “Last updated” date above.
