Privacy in Thalia and on this site.

Mabry Ventures LLC provides Thalia. This notice covers the Thalia website, its launch list, and the Thalia app.

Last updated September 27, 2026.

In the Thalia app

Thalia runs on your Mac. Your projects, chats, checkpoints and settings are stored on your Mac, and Thalia sends Mabry Ventures no analytics, telemetry or usage data.

When you chat, Thalia passes your messages and the files the agent reads to Meta’s Muse Code CLI, which sends them to Meta under your Meta account (or Meta Model API key) and Meta’s terms. Connectors you authorize, such as GitHub, Linear, Cloudflare, Sentry, or GitLab, receive what the agent asks of them under those services’ terms. Thalia’s named secrets and ElevenLabs key live in macOS Keychain. Keys entered for Thalia’s guided GitHub and Linear connectors, along with credentials in custom connectors configured through Thalia, also live in Keychain. Muse’s local settings file keeps the connector definition and Thalia bridge command without those values. Connectors managed directly in Muse, or older entries awaiting migration, may keep credentials in that local settings file as plaintext. Muse holds OAuth sign-ins in its own store. You can remove a connector or clear its token in Thalia, and revoke access at the service.

Thalia checks usethalia.com for app updates. Update checks do not include your projects, chats, or settings. If you ask Thalia to install the Muse Code CLI or check it for updates, Thalia downloads Meta’s installer or reads Meta’s public release information from api.meta.ai; those requests do not include your projects or chats. A diagnostics bundle is created only when you ask for one. Known secrets are redacted by default, and you can review the contents and change that setting before saving. The bundle leaves your Mac only if you send it.

Optional voice and search features

The features below send data to another service only after you choose them. The data goes directly from your Mac to that service, not to Mabry Ventures. Thalia does not save microphone recordings; transcribed text is handled like anything you type. Before changing voice settings or removing a voice key, End Talk or stop Dictation to close the current microphone session. Voice settings apply to the next session. Removing a key prevents new requests using the saved key, but a request already in progress may finish; revoke the key at the service if it should stop working everywhere.

Talk and Dictation with Apple Speech. Apple Speech is the default transcription service. The first time you use Talk or Dictation, Thalia asks how to transcribe. If you choose on-device transcription, or turn on “Keep transcription on this Mac” in Settings → Voice, new voice sessions transcribe audio on your Mac. End Talk or stop Dictation before changing settings, then start a new session to use the new choice. If you allow Apple’s servers, Apple may process your microphone audio on its servers.

Muse Voice Transcribe. If you select Muse Voice Transcribe in Settings → Voice and provide a Meta Model API key, Thalia streams your microphone audio during Talk and Dictation to Meta (api.meta.ai) for transcription, under that key and Meta’s terms. “Keep transcription on this Mac” overrides this choice for new voice sessions. To stop an active remote microphone session, End Talk or stop Dictation first. Then turn on that setting or select Apple Speech before starting again.

ElevenLabs spoken replies. Talk speaks its replies with Apple voices on your Mac unless you choose ElevenLabs under Spoken replies in Settings → Voice and add your ElevenLabs API key. Thalia then sends the text of each spoken reply to ElevenLabs (api.elevenlabs.io), under your key and ElevenLabs’ terms, and plays the audio it returns. Checking a new key sends the word “Ready.”, a voice preview sends a short sample sentence, and Thalia uses the key to list your ElevenLabs voices. To stop the current reply, use Stop Speaking or End Talk. Choose Apple for spoken replies or remove the key before starting a new conversation to change future replies.

Web search and page fetch. /search works only after you store a Brave Search API key named “brave-search-key” in Settings → Secrets. It sends the query you type to Brave Search (api.search.brave.com), under that key and Brave’s terms, and shows the results in your chat. /fetch downloads the page at the address you type directly from that website and attaches the page’s text to your next message. To turn off search, delete the key in Settings → Secrets.

Launch-list data

When you requested a launch notification, Mabry Ventures stored your email address, signup time, consent version, signup source, unsubscribe token, subscription status, and email-delivery status. We use this information to manage your request and send any remaining launch notification.

Where it goes

The website runs on Cloudflare. Launch-list records are stored in Cloudflare D1. Before the list closed, we used Resend for confirmation and signup receipt emails. We may use it to deliver one launch notification to eligible confirmed subscribers. Resend processes delivery and unsubscribe information for those messages. Cloudflare processes connection information to serve and protect the website. Before the list closed, the signup endpoint used your IP address temporarily to limit repeated requests; it did not add that address to the launch list.

We use Plausible Analytics to count visits to this site in aggregate — for example, which pages are viewed, which download buttons are clicked, which sites referred visitors, and approximate country. These visit reports go through usethalia.com, which passes your IP address and browser user agent to Plausible so it can count unique visitors; Plausible hashes them with a salt that changes daily. Plausible sets no cookies, does not follow you across other sites, and does not store your IP address or build a profile of you. We do not add advertising trackers or analytics cookies to this site. We do not sell the launch list or use it for unrelated marketing.

Keeping and removing your information

We keep launch-list records until you ask us to remove them or until the launch notification has been sent and list cleanup is complete, within 90 days of that notification.

To request removal or ask a question, email support@mabryventures.com from the address you used to sign up. We may need to verify the request before changing a record.

Launch list status

The launch list is closed. Existing confirmed subscribers who had not opted out before the audience cutoff may receive one launch notification. Pending confirmation links no longer add an address to the list. Each launch message includes a personal opt-out link; existing opt-outs remain effective. We do not enable open or link tracking for these emails. To request removal, email support@mabryventures.com from the address you used to sign up.
