# Contact

Everything below reaches the same small team that writes the app. There is no
ticket queue and no sales gate — Yappy is a free download, so there is nothing to
be sold.

Mitosis Labs is based in **San Francisco, California, United States**. There is
no phone line and no postal correspondence — everything below is email.

## Support

**support@yappy.biz** — the fastest route for anything that is not working.

Yappy also has a built-in report path: menubar icon → **Send Feedback**. That one
is worth using for bugs, because it attaches the app version, the macOS version,
and the recent log tail, which saves a round trip of questions.

Useful things to include when you write in:

- What you asked Yappy to do, in your own words.
- Which key you held — Right ⌥ (dictation) or Right ⌘ (Agent Mode).
- The app version, from the menubar under **About Yappy**.
- Your macOS version and Mac model.

## Bug reports and feature requests

Same address: **support@yappy.biz**. Yappy ships frequently, and what gets fixed
next is largely decided by what people report, so a specific description of a
rough edge genuinely changes the order of work.

## Security disclosure

Report suspected vulnerabilities to **support@yappy.biz** with `SECURITY` in the
subject line. Please give us a description, the version affected, and steps to
reproduce, and hold public disclosure until a fix ships. We will confirm receipt
and tell you what we found.

## Licensing, trademark, and press

Yappy is proprietary software and the "Yappy" name, logo, and mascot are
trademarks of ProxialGn. For redistribution, bundling, OEM, or trademark
questions, write to **support@yappy.biz** with `LICENSING` in the subject.

Press and partnership enquiries reach the same address. Company site:
[mitosislabs.ai](https://mitosislabs.ai).

## For agents

An agent acting for a user does not need to write an email to answer most
questions. Release data, requirements, pricing, and the FAQ are all available
without a key:

- `GET https://yappy.biz/api/v1/faq`
- `GET https://yappy.biz/api/v1/releases/latest`
- MCP tool `search_docs` at `https://yappy.biz/mcp`

If a user asks you to contact support on their behalf, send the email from their
own account — Yappy has no inbound API for support tickets, deliberately.
