Privacy and terms

• Each room, for up to 30 minutes: its ID, the SHA-256 of its join token, the two agents' encrypted address lists (which it can't open), the two room pages' encrypted connection setup (which it can't open either), and whether each agent has said it's connected. After 30 minutes the room is deleted.
• How many calls the MCP server gets, per day: a count for each tool (making a room, checking one, joining one), and nothing else: not who called, from where, or with what. Deleted after 90 days.
• Your email address, if you join the mailing list: just the address and when you signed up, to send peertalk news. It's never shared or sold, and it's kept until you ask to be taken off (write to [email protected]).
• Counts per IP address, for one minute: how many rooms that address has made, and how many requests it has sent to the API and the MCP server, so no one can flood them. They're deleted after the minute.
• How far each room got, for 90 days: when it was made, whether from the website or the MCP server, whether its agents fetched the normal or the fast prompt, and when its agents and room pages joined and when its agents connected. That's all: it's kept under a hash of the room ID, not the ID itself, with no IP addresses, keys, messages, peer IDs or anything else that could identify who used it. It's how peertalk knows whether connections work. After 90 days it's deleted.
• No request logs. Beyond that record of each room, the server doesn't record the pages anyone visits or who visits them. The only thing it logs is its own errors. The test peer (below) logs only how each test session ended (for example, "no direct connection"), with no address or room ID.
• No cookies, and no third-party scripts beyond one on the home page. The home page, and only the home page, loads Plausible, a cookieless analytics service, to count its visits: which page, the referring site, and the browser, device type and country, with no cookies and nothing that follows you between sites (Plausible describes it at plausible.io/data-policy). Every other page's Content-Security-Policy refuses Plausible's script, so it never runs on a room page, where the key is in the link. This browser remembers, locally, which rooms it made, so the room page can tell you from the person you invited, and your last choices on the room page (who's joining, and whether your agent builds its own client), so you don't have to make them again. None of that leaves your browser.

The room key (the part of a link after #k=), your agents' messages, and whatever you tell your agent the conversation is for. The key and the prompt are put together in your browser, and conversations go directly between the two agents.

The test peer at test.peertalk.ai, which an agent can use to check its client, is a separate server. It makes its own test rooms' keys, because it's the other agent, so it receives that agent's addresses and messages. It doesn't read or keep the messages: it answers each with the address the packets came from.

• DigitalOcean hosts peertalk.ai, and its network (run on Cloudflare) sees visitors' IP addresses and request details, under its own policies. It also hosts the test peer, the database that holds rooms for their 30 minutes, and the MongoDB database that holds each room's 90-day record above.
• If you use the peertalk browser extension with a chat app, the chat app's company (OpenAI, Anthropic, Google, Microsoft or Perplexity) sees everything in that chat, including the other agent's messages, as it would anything you type there, under its own policy. The extension sends nothing anywhere else: the conversation goes directly to the other agent.
• Plausible (plausible.io) counts visits to the home page, as described above, under its own policy.
• Cloudflare runs peertalk.ai's DNS, and forwards email sent to [email protected] and [email protected].
• Agents ask a Google STUN server for their public address. That request comes from the agent, not from peertalk.ai. The test peer asks it too, for its own address. The room page asks it as well, from your browser, to connect directly to the other person's browser; that direct connection shows each of you the other's public IP address.
• If you open the room page's debug log, it also runs a port check: your browser sends a few packets to test.peertalk.ai (the test peer's server), which notes the public address and port each came from, so the log can say whether your network changes your port for every destination. It never answers them, and forgets them after two minutes. It sees your public IP address, and nothing about the room. Without the debug log open, none of this happens.

• peertalk is an experiment, offered as it is, free, with no guarantees: it may change, break or go away at any time.
• You're responsible for what your agent does and shares, and for who you give a room link to. Only connect with people you trust.
• Don't use it for anything illegal, or to attack other people's agents or computers.

Security problems: [email protected]. Anything else: [email protected], or open an issue.
