What this policy covers

This policy covers all Blurt clients: the Mac app, the Windows app, the Blurt browser extension, and justblurt.com (including the /start setup wizard and the /connect sign-in page). Speech recognition works differently depending on which client you use, so read the next section carefully.

Where speech recognition happens

Mac and Windows apps:speech-to-text runs on-device, using your computer's built-in speech engine. Your audio and transcripts are processed locally and are never sent to Blurt's servers.

Browser extension: your audio is processed by your browser's speech service, not on-device.The extension uses your browser's built-in speech recognition (the Web Speech API) to turn your voice into text. In Chrome, that means your audio is sent to Google's speech recognition service to produce the transcript, governed by Google's own terms, not Blurt's. This is different from how the Mac and Windows apps work.

On every platform, Blurt's own servers never receive or store your audio.

Your account & what we store

Every Blurt client requires a Blurt account to dictate: a quick email sign-in, or one click at justblurt.com/connect for the browser extension. Your account manages your plan, weekly word count, and Premium features. We store your email address, your plan/subscription state, and your usage counts (e.g. words used) for billing and limits. Payments are processed by Stripe; Blurt never sees your card number. We do not run analytics on the content of your dictation, we do not sell personal data, and we do not run ads.

AI cleanup (Premium)

AI cleanup sends the text of a dictation (never the audio) to Anthropic's Claude to be reformatted, then returns it. On desktop, it is off by default. In the browser extension, it is on by default for Premium users, with a visible "Polish my speech" toggle in the extension popup so you can turn it off. If cleanup is on, your custom vocabulary words are included with the request so names and jargon are spelled correctly. Desktop supports bringing your own Anthropic key, stored securely on your device (macOS Keychain, or Windows Credential Manager on Windows); the extension uses only Blurt's hosted cleanup. Anthropic's API terms apply to that data, and Blurt's hosted cleanup does not retain your dictation text.

Custom vocabulary

Your custom vocabulary list (names, jargon, and other words you add) is stored in the extension's on-device storage. It is only sent off your device as part of an AI cleanup request, and only when cleanup is turned on.

One-click sign-in codes

justblurt.com/connect lets you sign the browser extension into your account with one click. It mints a single-use, short-lived sign-in code and hands it directly to the extension inside your browser. Session tokens are only ever sent over HTTPS and are never placed in a URL.

What stays on your device

In the browser extension, your settings (including your custom vocabulary list), your signed-in session, and a short recent-dictations list (a local backup so a missed insertion never loses your words) are kept in the browser's extension storage on your device; the recent-dictations list can be cleared from the extension popup and is never sent to Blurt's servers. On desktop, any transcript history is stored locally on your device and can be cleared in Preferences.
