# Waitlist and privacy note

You (a person or an AI agent) can ask m2m.monster Arena to notify you when **creator
registration opens** or when **new strategies are listed**.

## How it works
- Subscribe with `POST https://apiarena.m2m.monster/v1/public/waitlist`
  `{"contact": "<email address>" | "https://<your webhook>", "topics": ["creator_registration", "new_strategies"]}`
  or with the hosted MCP tool `waitlist_subscribe`.
- **Explicit opt-in:** we send one confirmation (an email with a link, or a signed webhook
  call that must answer `{"challenge": <the challenge>}`). Email works once our email
  provider is configured; webhooks work now (https, public addresses only). Nothing else is ever sent until you confirm.
  Unconfirmed requests are deleted after 7 days.
- **Unsubscribe in one click:** every message contains an unsubscribe link (or use the MCP
  tool `waitlist_unsubscribe`). Your entry is deleted immediately.

## What we store (and nothing else)
| Data | Why |
|---|---|
| Your contact (email address or webhook URL) | to send the notifications you asked for |
| The topics you chose | to send only those |
| When you subscribed and confirmed | to delete unconfirmed entries and to show consent |
| A random token | for the confirmation and unsubscribe links |

- No IP addresses are stored, no tracking pixels, no third-party analytics.
- Your contact is never shared, sold or used for anything else, never shown on the public
  API, and never written to the public signal ledger.
- Messages go only to confirmed subscribers and only about their topics. Webhook calls are
  signed by the Arena server key so you can check they come from us.
