Nuan Privacy Policy

Nuan is an AI-powered communication coaching product designed to help users communicate more effectively during and after conversations.

Depending on the features you use, Nuan may provide:

• real-time communication cues
• speech and pacing insights
• conversation transcripts
• post-call summaries and insights
• Thought Cue suggestions
• communication coaching
• meeting and calendar-related functionality
• meeting preparation: an objective, talking points, notes and files you add for a meeting
• an after-call check of whether your talking points came up and whether your objective was reached
• account and subscription management

Some processing happens on your device, and some is performed through Nuan’s servers and third-party service providers that deliver transcription, AI analysis, authentication, email, and payments. Files you attach are read on your Mac.

Account information. When you create a Nuan account, we may collect:

• your name or display name
• email address
• profile image
• authentication information
• account identifiers
• subscription and entitlement status
• account preferences

Passwords are handled through our authentication infrastructure and are not stored by Nuan in readable form.

Conversation and session data. When you use Nuan during a conversation, we may process information such as:

• speech or audio needed to provide transcription or coaching
• transcripts
• timestamps
• speaker-related information where supported
• communication patterns
• pace and filler-word information
• cue events
• topic or conversation-flow information
• Thought Cue requests and responses
• post-call insights and summaries
• the results of the after-call check of your objective and talking points

We use this information to provide the features you request.

Meeting preparation. If you prepare for a meeting in Nuan, we process what you add: an objective, talking points, notes, and the text Nuan reads from files you attach (PDF, Word, PowerPoint, plain text and Markdown). Files are read on your Mac; Nuan never uploads a whole file. Your preparation is stored on your Mac. Parts of it are sent to our AI model provider only as described in “AI processing” in section 6.

Audio. Nuan may process audio in real time to provide transcription and communication coaching. Nuan does not intentionally retain raw call audio on our servers unless a feature specifically tells you otherwise. If Nuan introduces an optional local recording or playback feature, we will clearly disclose how that feature works before enabling it for users.

Start Session reminder. From Nuan 1.0.12, Nuan can show a small reminder when another app on your Mac starts using your microphone, so you can start coaching. To do this, Nuan checks on your Mac which apps are using microphone input, using macOS’s audio system. It never listens to, records or saves audio for this, the names of those apps are not stored or sent anywhere, and nothing about it leaves your Mac. Nothing is recorded unless you press Start Session. The reminder is on by default, and you can turn it off at any time in Nuan’s Settings, under Meeting coaching.

Billing information. Payments and subscriptions are processed through Stripe. Nuan may receive billing-related information from Stripe such as:

• Stripe customer ID
• subscription ID
• plan
• billing interval
• subscription status
• renewal date
• transaction or invoice status

Nuan does not need to store your complete payment card number. Your Stripe billing email or payment email may differ from the email you use to sign in to Nuan. A payment email does not automatically replace your Nuan account email.

Website and technical information. When you use our website or services, we may collect information such as:

• browser type
• device type
• operating system
• IP address
• approximate location derived from IP
• application version
• diagnostic information
• error logs
• page interactions
• session activity

We may use cookies or similar technologies on Nuan Web for authentication, security, preferences, and analytics.

Calendar and integrations. If you choose to connect a supported calendar or third-party integration, Nuan may access information necessary to provide that integration, such as:

• meeting title
• date and time
• attendee information
• meeting links
• calendar identifiers

We only request integration permissions needed for the features being provided. You can disconnect supported integrations from Nuan or the applicable provider.

When you use Nuan while signed in, we collect limited technical and usage information about how the product is operating. Depending on the surface you use and what is available, this may include:

• the version and build of the Nuan desktop app, where available
• the most recent Nuan desktop version we have observed on your account
• your operating system, platform and processor architecture, where available
• when we first and last observed activity on the Nuan website
• when we first and last observed activity in the Nuan desktop app
• account and signup activity, such as when your account was created and which Nuan surface we first observed it on
• counts of coaching sessions, and counts of how often product features were used
• your subscription, plan and trial status
• crash reports and diagnostic information, which may include an error name, an error message, a technical stack trace, and the app build in which the error occurred

We use this information to:

• operate and improve Nuan
• understand how the product is used
• support users who contact us
• measure version adoption and tell you when an update is required
• investigate reliability problems and troubleshoot failures

This information is associated with your Nuan account so that we can answer questions about your own account when you contact us, and so that we can tell whether a problem affects one person or everyone.

Nuan’s product analytics record that a feature was used, never what was said.

Nuan analytics do not collect, transmit or store:

• conversation transcripts, or any part of them
• audio, or any recording of a conversation
• meeting titles or descriptions
• attendee emails or other attendee data
• calendar event content
• text you typed into My Thoughts
• generated Thought Cue content
• conversation content of any kind

Where a feature records usage, it records a count or a label and nothing else. For example, analytics may record that a filler-word cue appeared eighteen times during a session, or that the Repair mode of Thought Cue was opened. It does not record the words you used, the words Nuan suggested, or what the conversation was about.

Some features, such as transcripts and post-call insights, necessarily process conversation content in order to work at all. That processing is described elsewhere in this Policy and is separate from analytics. Content processed to deliver a feature to you is never repurposed as analytics.

Nuan’s product analytics require no additional permissions on your device.

Collecting this information does not request or rely on access to your microphone, screen, calendar or contacts beyond the access the product’s features already require and already explain, and it does not broaden any permission you have previously granted.

Nuan analytics do not collect:

• hardware serial numbers or device identifiers assigned by your device
• network hardware addresses
• device fingerprints
• your location

The technical information we record, such as your app version and operating system, is information the app already knows about itself in the ordinary course of running.

We may use information to:

• create and manage your account
• authenticate you
• provide real-time communication coaching
• generate transcripts and insights
• provide Thought Cue functionality
• help you prepare for meetings, and check after a call whether your talking points came up and whether your objective was reached
• maintain call history
• personalize your experience
• enforce trial and subscription entitlements
• process and manage subscriptions
• send account, security, and transactional emails
• provide customer support
• diagnose errors and improve reliability
• prevent fraud and abuse
• protect Nuan and its users
• comply with applicable law

We do not use your payment email as the primary mechanism for determining ownership of a Nuan subscription. Subscriptions are associated with the underlying Nuan account and billing identifiers.

AI processing. Nuan sends text through its own servers to our AI model provider to produce coaching, notes, insights and Thought Cue suggestions. What is sent, and when:

• During a session: parts of the transcript, to work out the topic of the conversation. Nuan’s pace, filler-word and other live cues are worked out on your Mac. If you prepared the meeting and have seen Nuan’s in-app notice about preparation, Nuan may also send your objective, talking points and short excerpts of your notes and attached-file text (at most 12,000 characters of your preparation in any one request, never whole files) for talking-point and wrap-up suggestions where they are available.
• Thought Cue: only when you tap it. Nuan sends recent transcript text and, for a prepared meeting after you have seen the in-app notice, the same kind of short excerpts of your preparation. Thought Cue sends nothing unless you tap it.
• After a session you keep: the transcript, to write notes, a summary and moments to improve. For a prepared meeting, once more: the transcript, the meeting title, your objective and your talking points, to check whether they came up. Notes and attached-file text are not sent for this check.

These features run automatically. If your account had “Save new sessions” turned off in an earlier version of Nuan, nothing is sent automatically until you choose Allow in the app; Thought Cue still works when you tap it. Your choice under “Keep sessions on this Mac” decides what is kept on your Mac; it does not turn AI processing off. When sessions are not kept, Nuan still works out the topic of the conversation during the session, but nothing is kept and no notes or insights are produced afterwards.

This section describes exactly how Nuan accesses, uses, stores, and shares data obtained through Google APIs. It is written from the shipping implementation rather than from intent, and it is the controlling description if anything elsewhere in this policy reads more broadly.

Sign in with Google

If you choose Sign in with Google, Nuan receives the basic account information Google returns for authentication: your Google account identifier, email address, name, profile information, and the OpenID authentication response. Nuan uses this only to authenticate you and to create and maintain your Nuan account. It is not used for advertising or profiling.

Google Calendar

Google Calendar is optional. Nothing is requested until you explicitly connect Calendar from Nuan’s settings, and Nuan works without it.

Nuan requests exactly one scope, and no other: https://www.googleapis.com/auth/calendar.events.readonly

When connected, Nuan reads upcoming events from your primary calendar only, limited to events starting within the next 30 days and to at most 50 events per read. From those events Nuan may access:

• the event identifier
• the title or summary
• the description
• start and end times
• the location
• the email addresses of attendees
• whether the event is confirmed, tentative, or canceled, and whether it recurs
• meeting links, taken from the event’s Google Meet link or found in the description or location field, including Zoom and Microsoft Teams links

The purpose is narrow: to recognize which meeting you are about to join or are currently in, so Nuan can label the session and tailor its coaching to the subject of that conversation rather than to a blank page.

How Google data is stored

Your Google OAuth access and refresh tokens are stored only on your own Mac, in an encrypted local store. The encryption key is derived using Electron’s safeStorage, which is backed by the operating system keychain. If Nuan finds that operating system encryption is unavailable, it refuses to store the tokens at all rather than writing them unprotected. Tokens are never sent to Nuan’s servers.

To show your upcoming meetings and match the current one, Nuan keeps a copy of the events it reads (the fields listed above) in a local database on your Mac, separately for each Nuan account. This copy is never sent to Nuan’s servers and is not stored in Nuan’s database. It is replaced each time Nuan reads your calendar, and deleted when you disconnect Google Calendar or delete your Nuan account.

What leaves your machine, and where it goes

One piece of Google Calendar data does leave your device, and we would rather state it plainly than make a blanket claim we cannot support. When a live session is matched to a calendar event, that event’s title becomes the session title, and the title is included in the requests that Nuan sends through its own backend to the AI model provider for coaching, notes, Thought Cue and meeting preparation features. The calendar event identifier is also retained on that session record so the session can be associated with the meeting.

No other Google Calendar field is transmitted. Descriptions, locations, attendee email addresses, and meeting links are used on your device to identify the meeting and are not sent to Nuan’s servers or to any AI provider.

Limited Use

Nuan’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.

Specifically, Google user data obtained through these APIs is not:

• sold to anyone, under any circumstances
• transferred to advertising platforms, data brokers, or information resellers
• used for serving advertisements, including personalized or interest-based advertising
• used to determine creditworthiness or for any lending purpose
• used to train or improve generalized or general-purpose AI or machine learning models

Human access to Google user data is limited to the narrow cases Google permits: with your explicit consent, where required for security or to comply with applicable law, or on aggregated and anonymized data for internal operations.

Disconnecting and revoking access

You can disconnect Google Calendar at any time from Settings inside the Nuan desktop app. Disconnecting asks Google to revoke the token and deletes the stored credentials and the local copy of your events from your Mac in the same step, so access ends immediately and nothing is left behind on disk.

You can also revoke Nuan’s access directly from your Google Account, at myaccount.google.com/permissions. If you revoke there, Nuan’s stored token stops working and is discarded the next time the app tries to use it.

Disconnecting Google Calendar does not by itself delete Nuan session records that were previously labeled with a calendar event title. To remove those, delete the sessions or your Nuan account, as described under Account deletion below.

Nuan relies on service providers to deliver portions of the product.

These may include providers for:

• AI model processing (OpenAI)
• transcription (Deepgram)
• cloud infrastructure
• authentication
• email delivery
• payment processing
• analytics and error monitoring
• calendar integrations

Information may be transmitted to these providers only as necessary to provide the relevant service. Our providers process information subject to their own contractual and privacy obligations.

Nuan does not sell your personal information to advertisers.

We do not permit advertisers to access your private Nuan conversations for advertising purposes.

We may share information with service providers that process data on our behalf to operate Nuan.

Nuan may offer limited promotional access to eligible users.

To stop free trials and uncounted sessions from being used again by deleting an account and creating a new one, we keep limited records about email addresses:

• that an email address has had its trial period, and the date it began. Nuan starts the trial period at an account’s first counted session, including on a paid plan.
• when an account is deleted, how many sessions it started that did not count toward a trial or plan: sessions started during onboarding, and sessions that could not start, for example because transcription did not connect. We keep these numbers for each email address the account used with Nuan, with the dates they were first and last updated.

These records hold a hashed form of the email address instead of the address itself, with the dates and numbers above and nothing else: no name, no account ID and nothing from your sessions. Before hashing, we ignore capital letters and, for Gmail addresses, dots and anything after a plus sign, so variations of one address count as one. We use these records only for trial and session eligibility, and we do not share them except with the providers that host Nuan’s servers.

We retain personal information only for as long as reasonably necessary for the purposes described in this Policy, including:

• maintaining your account
• providing the service
• meeting legal obligations
• resolving disputes
• preventing fraud or repeated promotional abuse
• enforcing agreements

When you delete your Nuan account, account-associated information will be deleted or de-identified according to our retention practices, except information we are legally required or reasonably permitted to retain.

On your Mac. Sessions are kept on your Mac according to your “Keep sessions on this Mac” setting, which can delete older sessions automatically. Meeting preparation, the text read from attached files, and the results of the after-call check are kept on your Mac until you delete them or the meeting, or delete your Nuan account in the app on that Mac. Choosing not to keep sessions does not turn off AI processing (see “AI processing” in section 6).

Product analytics and diagnostics. Records of individual product events that are linked to your account are retained for up to 180 days, after which they are deleted. Crash and diagnostic information containing technical detail such as error messages and stack traces is retained for up to 90 days.

We also keep aggregated statistics, for example the total number of coaching sessions started across all users in a given week. Aggregated statistics are not linked to any account and may be retained indefinitely. Because they contain no information about any individual, they are not affected by deleting an account.

You may request deletion of your Nuan account through the product where available.

Deleting an account may permanently remove:

• your profile
• account history
• associated cloud data
• subscription relationship
• other data associated with that account
• product analytics and activity records associated with that account
• on the Mac where you delete it: that account’s meeting preparation, attached-file text, after-call results, and local calendar copy

Aggregated statistics that contain no information identifying you are not reversible by deletion, because they no longer describe any individual account.

Depending on the feature and applicable law, you may be able to:

• access your account information
• update your display name
• change your profile image
• change your account email
• change your password
• manage subscription information
• disconnect integrations
• delete your account
• choose how long sessions are kept on your Mac
• delete meeting preparation and attached files
• start a session without your preparation (Start without context)
• if your account had “Save new sessions” off in an earlier version, choose whether to allow AI processing
• manage certain product preferences

You may also contact us regarding privacy requests.

If applicable, California residents may have rights regarding their personal information, including rights to request access, correction, or deletion of certain information and to receive information about how personal information is collected and disclosed.

Nuan does not sell personal information for monetary consideration.

To exercise applicable privacy rights, contact us using the information below. We may need to verify your identity before completing certain requests.

Privacy and recording laws vary by jurisdiction.

Some jurisdictions require the consent of all participants before a conversation may be recorded or processed.

We use reasonable administrative, technical, and organizational safeguards designed to protect personal information.

However, no system, network, or storage technology can guarantee absolute security.

You are responsible for protecting your account credentials and maintaining the security of devices on which you use Nuan.

Nuan is not intended for children under 13.

If we learn that we have collected personal information from a child in violation of applicable law, we will take appropriate steps to delete it.

Nuan is operated from the United States.

If you access Nuan from another country, your information may be processed in the United States or other jurisdictions where our service providers operate.

We may update this Privacy Policy periodically.

If we make material changes, we may notify users through the product, website, email, or another appropriate method.
