Privacy policy
Metatron is built so that your calls, notes and email stay on your Mac. We don't run a server that receives them, so we can't read, sell or train on them. This page explains the few things that do leave your Mac, and why.
Who we are
This policy covers Metatron, the Mac app, and usemetatron.com ("we"). For anything about privacy, write to [email protected].
What stays on your Mac
- Call audio, recordings and transcripts. Speech to text runs on your Mac with Apple's on-device model; if that model isn't available for a language, Metatron doesn't listen in that language rather than use a server.
- Your notes, to-dos, reminders and call summaries, saved as files in the folder you choose.
- Metatron's own files: recordings, transcripts, attachments and reminders in
~/Library/Application Support/Metatron, logs in~/Library/Logs/Metatron, keys and your licence in the macOS Keychain. - If you use Claude Code or Codex, that tool keeps its own copy of your questions on your Mac for one day, as Metatron sets it. Settings → Privacy → Delete everything removes those too.
We never receive any of it. Delete a file and it's gone; there's no copy anywhere else.
What leaves your Mac, and where it goes
- Your AI provider, if you choose a cloud one. When Metatron writes notes or answers a question with Claude (Anthropic) or ChatGPT (OpenAI), the text it needs for that goes to that provider under your own plan or key: your request, the relevant notes and to-dos, your calendar for the next two weeks, the call transcript when it writes notes, and anything you attach, such as a screenshot, a chat you ask about, or a document you add. Never the audio. Their privacy terms apply to that text. If you choose a model on your Mac, nothing goes anywhere.
- Claude Code and Codex. Metatron talks to your plan through Anthropic's and OpenAI's own tools, installed on your Mac. Metatron switches off their usage reporting and crash reports; their sign-in and the requests themselves are governed by their policies. With "Web search" switched on, searches go through your AI provider too.
- Apps you connect. Calendar, email and other apps you connect are read on your behalf through your own accounts, and what is read is handled by your AI like any other text. With Gmail on, Metatron checks new mail every few hours. You can switch each app off at any time.
- Licence checks. To activate and check your licence, Metatron sends your licence key and your Mac's computer name to Lemon Squeezy, when it opens, about once a week.
- Update checks. Metatron asks usemetatron.com whether there's a new version. That request carries your Metatron and macOS versions and your internet address, nothing else.
- Downloads you choose. When you pick Claude or ChatGPT, Metatron downloads their tool from Anthropic's claude.ai or OpenAI's GitHub. The first time it transcribes a language, macOS downloads Apple's speech model. The first time it tells voices apart on a call, it downloads a small speaker model from Hugging Face. None of these carry your data.
Metatron contains no analytics, no tracking and no advertising code.
When you buy
Purchases are handled by Lemon Squeezy, the merchant of record, which processes your payment and taxes. We receive your name, email address, country and order details so we can send your licence, help you and handle refunds. We never see your card details. Lemon Squeezy's own privacy policy covers what it collects.
