Privacy Policy

Version 2026-11-01 · Effective November 1, 2026 · Team Nebula · Blurt for Mac

Blurt can transcribe and process speech on your Mac. Choosing a cloud provider sends the content needed for that feature to the provider. Accounts, sync, payments and diagnostics have their own behaviour, described below. This policy covers the Blurt Mac app, the Blurt website and the Blurt services behind them. Team Nebula runs Blurt and is the company responsible for your data. The Terms of Service are the agreement for using Blurt.

The short version

• What we collect: your account email if you sign in, anonymous usage data (on by default, off in one switch), the notes you choose to sync (end-to-end encrypted), billing details handled by our payment processor, your feedback and ratings, and the email address you give the waitlist.
• What we never collect: Blurt does not store audio by default. We do not sell your data, use it for advertising, or read your encrypted notes.
• Who helps us run it: Google Cloud, Resend, Stripe and any other payment processor, and the speech or writing providers you choose yourself.
• Your control: you can switch features off, export or delete your data, and ask us to delete your account.

Your privacy depends on your settings

How private your voice and text stay depends on the choices you make and on the environment you use Blurt in: which providers you select, whether you sign in, which sync and sharing options you turn on, and the security of your own Mac, accounts and network. Blurt has done its best to make the private choice the easy one, but it cannot guarantee absolute security or privacy. Anyone who can use your unlocked Mac, or who has your account or provider keys, can reach what Blurt can reach.

Speech, writing and voice

• On-device transcription processes audio on your Mac. A custom remote transcription endpoint receives audio even if the provider is labelled Local.
• Cloud transcription sends audio directly to the provider you select, using your provider key. Dictionary spellings can also be sent as recognition hints; this has a separate setting.
• Style and writing assistance use the content and instructions needed for the requested action. With an on-device model, processing stays on your Mac. With a cloud model, that text goes to the configured provider.
• Blurt Cloud is Blurt-hosted transcription and Style for Macs that cannot run the on-device models. Audio and text are held in memory for the length of one request, passed to the model provider that does the work, and not saved by Blurt.
• Live Blurt and agent voice can speak text with an on-device voice. Selecting a cloud voice sends the text to that voice provider.
• Provider keys are encrypted at rest with macOS Keychain-backed storage. A saved key authenticates requests to its provider; it is not included in prompts or transcript payload fields.

Notes, meetings and local storage

Blurt stores dictation history, notes, meeting documents and agent conversations locally. Notes you write are kept until you delete them. Privacy & storage contains retention controls for history and agent sessions.

Blurt does not store audio by default. Dictation audio is not saved. Meeting capture uses your microphone and, when authorized, system audio. Audio files can be kept temporarily for processing and recovery. Keep meeting audio is off by default; successful processing removes unneeded recordings when this is off. Failed processing and pending sync can delay cleanup. If you enable retention, recordings are subject to the configured age limit and a 500 MB cap for eligible files.

Automatic meeting recording is off by default. Optional calendar access helps show upcoming meetings. Optional model-based meeting artwork selection sends limited meeting metadata to the configured model only after consent; it does not send the transcript for decoration. You are responsible for telling people you record and getting any consent the law requires.

Accounts and cloud features

An account is optional. Mac sign-in uses Google in your browser. The identity service also supports Apple credentials for compatible clients. Google and Apple sign-ins are separate accounts unless an explicit linking flow is provided.

The identity service derives an account identifier from the provider subject. It supports learning profiles and the leaderboard. It does not store transcript history or notes. Content sync requires a separately configured compatible Blurt content service; signing in does not establish that every sync feature is available.

• Account email: the account email from your Google or Apple sign-in is used to sign you in, to check invite access and to send the welcome email. The identity service keeps keyed hashes and masked labels where it can, rather than the plain address.
• Learning profiles: while signed in to a supporting service, the Mac can sync dictionary correction pairs and snippets automatically. New recognition-only hints are excluded from profile sync. This is separate from transcript delivery.
• Synced notes are end-to-end encrypted. Notes and meeting notes you sync are sealed on your Mac with a key we do not hold, so the service stores text it cannot read. A locked recovery copy of that key can be stored with your account, and we cannot open it. If you lose every copy of your key, we cannot recover your synced notes. Ordinary-note sync follows sign-in when the service supports it; syncing meeting notes needs the separate meeting-note sync opt-in.
• Transcript delivery: starts off. When enabled while signed in, eligible non-Local transcript text is sent to the configured content service. Local-provider entries are excluded. Delivery does not provide a remote history browser or send audio.
• Welcome email: when enabled by the service, the email claim from your first provider sign-in is used to send a transactional welcome message through Resend. The identity service stores an account-keyed delivery ledger, rather than the email address.

Leaderboard and install count

The leaderboard is on by default for signed-in users. It sends your nickname, total word count, speaking speed and vocabulary ratio to the identity service. Other signed-in users can see your nickname, score, word count, speed and rank. Turning it off removes your entry.

For the leaderboard's install count, Blurt can send a randomly generated install identifier at most once a day, including while signed out. The service records its first and last activity dates and counts installs seen within 90 days. This identifier is separate from your account and is not derived from your hardware. This report is separate from the anonymous usage data switch.

Anonymous usage data

Blurt shares anonymous usage data by default. It helps us see which features people use and what breaks. You can turn it off any time in Settings › Privacy & storage › Share anonymous usage data. Turning it off stops sending at once and deletes anything not yet sent.

What is sent. Only numbers, on/off values, ranges and items from fixed lists:

• When Blurt opens, closes, stays running (once a minute) or crashes, as a short reason code.
• Each dictation: how long it took, a word-count range (such as 10–24), hold-to-talk or continuous, which provider, model, Style and language setting, and whether it worked.
• Which features you use (notes, meetings, Style, Dictionary, snippets, history, agent voice), which setup steps you reach, update checks, and the names of settings you change.
• Whether Microphone, Accessibility and Input Monitoring are granted.
• Error categories (such as “dictation_recording”), never the error message.
• Blurt's own CPU and memory use during a dictation.
• About your Mac: app version, macOS major version (such as 15), chip family (such as Apple M3), a memory range (such as 16 GB) and your system language (such as English).

What is never sent. Audio, transcripts, notes, meeting content, clipboard contents, Dictionary words, keys, file names or paths, app or window names, your Mac's name, your username, your email, or your account.

How it stays anonymous. Events carry a random telemetry ID made on your Mac. It is not your account ID and is never sent with account data. Signing in does not change it. The service checks every event against a fixed list and refuses anything else. It does not store your IP address. Our hosting provider (Google Cloud Run) keeps its own request logs for up to 30 days, and those include IP addresses; we exclude this route from them.

How long it is kept. 13 months, then it is deleted.

Configured Sentry crash reporting is separate and stricter: it can include error text, so it only runs if you turn usage data on yourself in Settings. Its payloads are filtered to exclude audio, transcript and note contents, clipboard contents, credentials, window titles and private file paths.

Waitlist and invites

While the beta is invite-only, you can join the waitlist from this website or from the app. We keep the email address you enter, where you joined from (website, Mac or iPhone), when, and which version of the Terms and Privacy Policy you accepted, so we can send you an invite when your spot comes up. We use it only for that invite, never for marketing, and never share it except with Resend, the service that delivers the email.

The service stores your entry under a keyed code made from the address, not under the address itself, and it does not store your IP address. Your network address is held in memory for up to an hour, only to limit repeated sign-ups. To be removed from the waitlist, email hey.blurt@teamnebula.ai from that address.

An invite link opens a page on the Blurt website that reads the invite from the link in your browser. The page does not send the link anywhere; Open in Blurt hands it to the app.

Records of your acceptance

When you accept the Terms and this policy, Blurt records which version you accepted and when. On the website this is stored with your waitlist entry. In the app it is stored on your Mac and, once you sign in or redeem an invite, with your account on the identity service, so we can show that you agreed and ask again when the documents change.

Payments

Paid plans are billed through Stripe and any other payment processor shown at checkout. They collect and process your card or payment details under their own privacy policies; Blurt does not receive or store your full card number. We receive what we need to run your plan, such as your plan, its status and renewal date, and the email on the payment. Tax and accounting laws can require us and our processors to keep payment records for several years.

Ratings

After you have used Blurt for a while, it may ask you to rate it from 1 to 5 stars, with an optional comment of up to 1,000 characters. You can choose Not now. A rating sends the stars, your comment, which app (Mac or iPhone) and the app version. It is not linked to your account, even when you are signed in, and the service does not store your IP address. Comments are read by the Blurt team to improve the product and are kept for 13 months, then deleted. Do not put personal or confidential information in a comment.

If you give 4 or 5 stars, the app may also invite you to leave a public review. On iPhone that uses Apple's own review prompt, which Apple limits to a few times a year.

Who processes data for us

We use a small number of providers to run Blurt. They may only use the data to provide their service to us. We do not sell your data or use it for advertising.

• Google Cloud hosts the Blurt services, the database that holds accounts, invites, waitlist entries and synced (encrypted) notes, and the store for anonymous usage data. Its servers used by Blurt are in the United States.
• Resend delivers Blurt's emails, such as invites and the welcome message.
• Stripe and any other payment processor shown at checkout process payments and manage subscriptions.
• Google and Apple provide sign-in when you choose to sign in.
• Sentry receives filtered crash reports only if you turn usage data on.
• Providers you choose for cloud speech, writing and voice receive the content for the feature you use, under their own terms. Model downloads and update checks contact their distribution services.

We may also disclose information if the law or a valid legal request requires it, to protect people’s safety or Blurt’s security, or to a successor if Team Nebula is sold or merged, with the same protection for your data.

How long we keep data

• On your Mac: until you delete it or your retention settings remove it.
• Account and learning profile: while your account exists, then deleted when you ask us to delete it.
• Synced notes: until you delete them or your account. A content-free deletion marker can remain so your other devices stay in step.
• Anonymous usage data and ratings: 13 months, then deleted.
• Waitlist entries: until you are invited and for a reasonable time afterwards, or until you ask to be removed.
• Records of acceptance: while your account exists, or for as long as we need them to show what you agreed to.
• Hosting logs: up to 30 days.
• Payment records: as long as tax, accounting and payment-network rules require.

Your rights, deleting and exporting your data

You can choose local providers, sign out, turn off transcript delivery, meeting-note sync, anonymous usage data and leaderboard participation, and delete local content from the app. Signing out does not delete copies already held by a service.

Wherever you live, you can ask us to:

• tell you what personal data we hold about you and give you a copy, in a form you can export;
• correct data that is wrong;
• delete your account and the data we hold for it; and
• stop using your data for a purpose you object to, or withdraw a consent you gave.

If you are in the EEA, the UK or Switzerland (GDPR and UK GDPR), you also have the right to restrict processing, to data portability and to complain to your data protection authority. We rely on your consent, on the need to provide Blurt to you, and on our legitimate interest in keeping Blurt secure and improving it. If you are in California (CCPA/CPRA), you have the right to know what we collect, to delete it, to correct it and to opt out of the sale or sharing of personal information. We do not sell or share personal information for cross-context advertising, and we do not treat you differently for using these rights.

To make a request, email hey.blurt@teamnebula.ai from the address on your account. We may ask you to confirm it is you, and we aim to answer within 30 days. The current Mac Account screen offers sign-out; do not rely on it as an account-deletion action. Removal depends on the service holding the data. The random install-count record is not linked to an account, so it cannot be tied to a deletion request.

Security

We use reasonable technical and organisational safeguards: encryption in transit, encrypted storage of provider keys on your Mac, end-to-end encryption for synced notes, keyed hashes for identifiers, and access limits on our services. No method of storing or sending data is completely secure, and we cannot guarantee absolute security. Keeping your Mac, account and keys secure is part of the protection, as the Terms explain. If a breach affects your personal data, we will tell you and the authorities as the law requires.

Children

Blurt is not for children. You must be at least 16 to use it, and we do not knowingly collect personal data from anyone younger. If you think a child has given us data, email us and we will delete it.

Other services and platforms

Licence activation sends your licence key to Blurt's validation service. Cloud speech, writing, voice, authentication, email, payment and diagnostics providers handle the data they receive under their own policies.

This page describes the current Mac implementation. Blurt for iPhone has a different storage and permission model; consult the privacy information supplied with that release or contact us for details.

Changes to this policy

This policy has a version number and an effective date at the top. When a change is material, Blurt will ask you to read and accept the new version, and we will say so in release information.
