Privacy policy

Last updated 15 November 2026

TERAOS is a voice companion for the Mac, made by Tera Labs USA LLC ("we"). It has two parts: the TERAOS app on your Mac, and TeraCloud, our server, which signs you in, counts your usage, passes your requests to the AI model, and connects the apps you choose. This policy explains what each part collects and what happens to it.

What stays on your Mac

• Your voice. Speech recognition and the voice that answers run on your Mac. Audio isn't sent to TeraCloud.
• Your conversations and memory. Conversation history and the things you ask TERAOS to remember are kept in a database on your Mac.
• Your own API keys. If you add keys for other AI providers in Settings, they are stored in your Mac's Keychain, and requests that use them go straight from your Mac to that provider, under that provider's terms.

What TeraCloud receives and keeps

Your account

• Your email address, from Sign in with Apple or Sign in with Google, and when the account was created and last used. If you use Apple's "Hide My Email", we see only the relay address. We don't keep your name.
• Sign-in sessions, stored only as one-way hashes so a copy of our database can't be used to sign in as you.

Your plan and usage

• Your plan, its status and billing period, and the Stripe customer and subscription identifiers that link your account to Stripe.
• How many talk turns and agent messages you used in each period, and what they cost us. We use this to apply your plan's limits.

Connected apps

• When you connect Gmail, Google Calendar, Google Drive, Slack or Outlook, we keep the account you connected (its email address or Slack workspace name), the permissions you granted, and the sign-in tokens the provider issued.
• The tokens are encrypted on our server (AES-256-GCM) with a key that never leaves it, and are decrypted only to make a request you asked for.

Server logs

• Each request is logged with its method, path, result code and duration. Logs don't contain what you said, what was answered, your IP address or your email address. Your IP address is used for a short time in memory to limit abuse, and isn't stored.

What passes through TeraCloud without being kept

To answer you, TeraCloud forwards your request to the AI model and sends the answer back. It does not store:

• what you say to TERAOS or what it answers,
• screenshots, which are taken only when you ask about your screen or let TERAOS operate your Mac,
• the emails, events, files or messages it reads from your connected apps to answer you.

Who processes your data

• Anthropic (the Claude API) receives your requests, including any screenshots and app content needed to answer them. Anthropic processes them under its commercial terms, which don't allow it to train its models on this content, and may keep them for a limited time for safety monitoring. See Anthropic's privacy policy.
• Stripe processes payments. We never see or store your card number. See Stripe's privacy policy.
• Apple and Google handle sign-in and tell us your email address.
• Google, Slack and Microsoft receive the requests TERAOS makes to your connected accounts, only when you ask for something that needs them.
• Amazon Web Services hosts TeraCloud in Frankfurt, Germany.

We don't sell your data, share it with advertisers, or use it to show you ads. The teraos.co website uses no cookies and no analytics.

Google user data

When you connect a Google account, TERAOS asks only for the permissions it needs: reading and sending Gmail, reading and adding Google Calendar events, and reading Google Drive files. It uses them only to do what you ask, in the moment you ask.

TERAOS's use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

• Data from Google APIs is sent to the AI model only to answer your request, and is not used to develop, improve or train generalized AI or machine-learning models.
• We don't transfer it to anyone else, except as needed to provide the feature you asked for, to comply with the law, or with your consent.
• No person at Tera Labs reads it, unless you ask us to for support, it's needed for security, or the law requires it.

When TERAOS acts for you

TERAOS can click, type, send messages and change things in your apps and in your Chrome browser. It asks for your approval before anything that changes something, such as sending an email or adding an event, and shows you what it's about to do. In Chrome, the page shows a banner while TERAOS works, with a Stop button. Page content it reads is treated as information, never as instructions.

How long we keep data

• Account, plan, usage and connected-app data: while your account exists.
• Server backups: up to 14 days.
• Payment records: Stripe keeps them for as long as the law requires.

Deleting your account

You can delete your TERAOS account from the app. That removes your account, sessions, plan record, usage and every connected app from TeraCloud, and revokes TERAOS's access at Google, Slack and Microsoft where they allow it. If your paid plan still renews, cancel it in Manage billing first. Deleted data leaves our backups within 14 days. You can also disconnect any app at any time from the Apps screen, or remove TERAOS from your Google, Slack or Microsoft account settings.

Security

All traffic to TeraCloud uses HTTPS. Sign-in sessions are stored as hashes, connected-app tokens are encrypted, and the server holds only the keys it needs.

Children

TERAOS isn't for children under 13, and we don't knowingly collect their data.

Changes

If we change what we collect or how we use it, we'll update this page and the date at the top before the change takes effect.
