Privacy Policy

Marcus is designed to help users manage work across email, calendar, meetings, and tasks. This policy explains what we collect, how we use it, and the limits we place on ourselves when handling connected account data.

Information we collect

We may collect information about you in a variety of ways, including:

Personal Data:

• Name and email address
• Profile information
• Authentication credentials

Usage Data:

• Device information and identifiers
• Log and usage data
• Location information (with your permission)
• Calendar and email data (with your permission)

Third-Party Integration Data:

• Google account information (when you connect Google services)
• Microsoft account information (when you connect Microsoft services)
• Apple ID information (when you sign in with Apple)
• Slack workspace data (when you connect Slack)

Meeting recordings and transcripts:

• When you ask Marcus to join an online meeting, our meeting bot provider Recall.ai joins, records and transcribes it. When you record a meeting in the app, the audio goes to ElevenLabs to produce a transcript. Marcus's servers do not keep the audio after the transcript is produced.
• A recording made in the app stays on that device until it uploads. After that the app keeps a copy on the device for 30 days by default. You can change this, turn it off, or delete recordings in Settings.
• The transcript, the summary, the action items and any speaker names you assign are stored with your account so you can read, search and act on them.
• Recordings capture everyone in the meeting. You are responsible for telling participants that the meeting is being recorded and for obtaining any consent the law where you are requires.
• You can delete a meeting in the app, set transcripts to delete automatically in Settings, or ask us to delete a meeting or your whole account at the address below.

Dictation:

• When you dictate in Marcus chat, in a Marcus note, with the Mac shortcut, with the iPhone shortcut or with the Marcus keyboard, your recording is sent to Google AI to turn it into text, and that text is sent to OpenAI to remove filler words and add punctuation. Marcus does not store the recording on its servers. It does not store the text either, and the text goes only to the place you are typing or to your clipboard, unless you use the Mac's Ask Marcus shortcut. These providers handle it under their own terms.
• If the upload fails, the recording stays on your device so you can try again, and is deleted when you retry or cancel. If Marcus can't be reached, your device may turn it into text itself.
• When you save a dictated note, it is stored in your account like any other note, and Marcus can learn from it.
• The Mac's Ask Marcus shortcut sends what you said to Marcus as a chat message. It is saved in your chat, and Marcus can act on it and learn from it like anything else you tell it.
• If you allow Input Monitoring on a Mac, Marcus uses it only to check whether its fn shortcuts are held and whether another key is pressed at that moment. It does not read or keep what you type.
• Marcus keyboard dictation is off until you turn it on. While it is on, Marcus holds the microphone and shows that on your Lock Screen, saves audio only between your taps on the keyboard's mic, and turns off after ten quiet minutes. Marcus does not collect what you type on the Marcus keyboard.

Voice calls and voice notes:

• On a live voice call with Marcus, your voice is sent to xAI as you speak.
• Chat voice notes, and voice messages you send on Telegram or WhatsApp, are sent to Google AI to become text. The text is saved in your chat.

What Marcus learns about you:

• By default, Marcus learns from your meetings, notes, chats, voice calls, and daily work such as tasks and commitments, so it can remember context and give you more personal help. This can include commitments found in email you connect.
• Meeting transcripts include what other people said.
• You can review, correct or reset what Marcus has learned, and exclude a source, in Settings under Memory. If you turn off "Remember across conversations", Marcus keeps what it has but won't use it or save anything new until you turn it back on.

Analytics and advertising measurement:

• Our website uses Google Analytics and the Meta Pixel, which use cookies. Our apps use Firebase Analytics and the Facebook SDK to measure events such as sign-ups, trials and purchases.
• When you start checkout, start a trial or buy, we may send that event to Meta and Google to measure our advertising. It can include a hashed email address, a hashed or plain account ID, your IP address, your browser details and advertising cookies.
• We do not send the contents of your meetings, notes, chats, email or calendar to them for this.

How we use data

We use the information we collect to:

• Provide, maintain, and improve our services.
• Process your authentication and account management.
• Communicate with you about the app.
• Analyze usage patterns to enhance user experience.
• Provide AI-powered features and insights, such as summarization, prioritization, and drafting assistance.
• Integrate with third-party services you authorize.
• Comply with legal obligations.

How Google user data is handled

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

We do not sell, rent, or trade Google user data. When Marcus processes Gmail or Calendar information, it is used only to deliver the features the user requested. Google user data is never used for advertising, ad targeting, retargeting, or interest-based advertising of any kind.

Limited data may be sent to the following trusted sub-processors solely to perform the work you requested:

• OpenAI, Anthropic, Google AI — AI processing for summarization, drafting, and prioritization features. These providers process data to return a result. They may keep it for a limited time under their terms, for example to detect abuse.
• Firebase (Google Cloud) — Secure storage of minimal cached metadata (e.g. email subjects, dates, sender names) scoped to your account for app performance. This data is deleted when you disconnect your Google account.

Legal Requirements:

• We may disclose your information if required by law, court order, or governmental authority.

What we do NOT do:

• We do not sell your Google user data to any third parties.
• We do not share your Google user data with advertisers or marketing companies.
• We do not use your Google user data for targeted advertising, retargeting, or interest-based advertising.
• We do not transfer your Google user data to data brokers or information resellers.
• We do not use your Google user data for purposes other than providing and improving Marcus AI functionality.

Your Google user data is accessed to provide the features you have connected, including background calendar and email sync, and is used exclusively to provide those services.

Data retention and deletion

We retain your data only for as long as necessary to provide the service. Meeting transcripts follow the retention setting you choose in the app. Cached Google account data is deleted when you disconnect your integration. You may request full deletion of your account and associated data at any time by contacting us at info@cettechventure.com. Deletion requests are processed within 30 days.

Security and storage

We use secure cloud infrastructure, scoped authentication, and encrypted transport where appropriate. No internet-based system can guarantee absolute security, but Marcus is built around least-privilege access and backend-owned provider credentials for stronger operational control.

Where your data is processed

CET TECH LLC is based in the United States. Our servers and most of the providers named here are in the United States, so your data, including audio, may be transferred outside your country.

Your rights

You have the right to access, correct, export, or delete your personal data at any time. To exercise any of these rights, contact us at info@cettechventure.com. If you are in the EU, Türkiye or California, additional rights may apply under GDPR, KVKK or CCPA respectively.

Children's privacy

Marcus is not intended for users under the age of 18. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

Third-party services

Our app integrates with third-party services including:

• Google (Gmail, Calendar)
• Microsoft (Outlook, Calendar)
• Apple (Sign In with Apple)
• Slack
• OpenAI, Anthropic, Google AI and xAI (AI processing)
• ElevenLabs and Recall.ai (meeting audio and transcripts)
• Telegram and WhatsApp (when you connect them)
• Stripe and RevenueCat (payments and subscriptions)
• Google Analytics, Firebase Analytics and Meta (analytics and advertising measurement)
• Render and Firebase (hosting and storage)

When you connect these services, you are subject to their respective privacy policies. We only access the data necessary to provide our services and in accordance with the permissions you grant.
