Short answer: Granola is a well-built tool with a real security program. It is not a local tool. No bot joins your call, which makes it feel private. The audio it captures on your Mac still goes to the cloud for transcription, and your notes live in Granola’s cloud too. Whether that counts as “safe” depends on what people say in the meeting.
Bot-free and local are two different things
Granola’s signature move is capturing audio from your Mac instead of sending a bot into the call. Nothing joins the meeting, nobody sees “Granola Notetaker” in the participant list, and there is no awkward consent moment with a robot in the room.
Where the audio is captured and where it is processed are separate questions. Granola captures on your Mac, then sends the audio to the cloud for transcription and runs its AI features through large-model providers. It stores your notes and transcripts in its cloud and syncs them across devices, which is what makes its sharing and mobile features work.
The accurate description is bot-free capture, cloud processing, cloud storage. As of this writing, Granola’s own documentation describes real-time transcription through cloud speech providers, transcripts and notes retained in your account, and audio itself not kept after transcription.
None of that is a scandal. Nearly every cloud notetaker works this way, including the ones that do use bots, like Otter. It does mean the content of your meeting transits and rests on infrastructure you don’t control, operated by Granola and its subprocessors.
“Safe” depends on the meeting
For a daily standup or a podcast prep call, cloud processing is a non-issue. The calculus changes when the conversation itself is the sensitive asset:
- NDA and client work. Many NDAs restrict disclosing covered information to any third party. A transcription vendor and its AI subprocessors are third parties. Some agreements permit standard service providers; many don’t say, and “we assumed it was fine” is a weak position.
- Legal, M&A, and board conversations. Privilege and deal-confidentiality arguments get weaker each time content leaves your custody.
- Hiring, HR, and user research. You are recording other people’s words. GDPR and similar regimes make you responsible for where that data goes, and “it went to a US cloud provider and their model vendors” is something you must be able to disclose.
- Healthcare, finance, and anything regulated. If a compliance officer would ask “where is the audio processed?”, you need a better answer than a marketing page.
If your meetings live in the first category, Granola is a reasonable choice. If any land in the second, the question shifts from whether Granola’s cloud is well secured to whether the content should be in anyone’s cloud at all.
Questions to ask any notetaker
Before you trust a tool with confidential calls, get concrete answers to five questions:
- Is the audio processed on my machine, or uploaded for transcription?
- Which subprocessors (speech and LLM providers) see the content?
- Does the vendor use my content for model training, and is the opt-out on by default?
- What does the vendor retain after the meeting (audio, transcript, notes), and for how long?
- Can I export and delete everything, and where do the notes physically live?
Cloud tools differ on questions 2 through 5. Only local tools change the answer to question 1, and question 1 makes the other four mostly moot.
Common questions about Granola’s security
Facts below are from Granola’s Security, Privacy & Data FAQ as of September 2026. Check the source before relying on them; vendors change policies.
Is Granola AI safe?
For everyday meetings, yes. Granola is SOC 2 Type II certified, encrypts data in transit and at rest, and deletes the audio once transcription finishes. For confidential meetings the bar is different: the audio is still transcribed in Granola’s cloud, and your notes and transcripts are kept on its servers until you delete them. HIPAA coverage, with a signed BAA, is limited to the Enterprise plan as of September 2026.
Where does Granola store data?
On Amazon Web Services servers in the United States, encrypted at rest, with a local cache of your notes on your Mac. Audio is cached only while a meeting is transcribed and then deleted. Notes and transcripts are retained indefinitely unless you delete them or an admin sets a retention policy.
Does Granola record audio?
It captures system audio and your microphone on your Mac during the meeting, uploads that audio for transcription, and deletes it afterwards. It does not keep a recording you can play back.
Does Granola use my meetings to train AI?
By default on Free and Business plans, anonymised data may be used to improve Granola’s own models; you can switch this off under Settings → Preferences → Data & sharing. Granola states that third-party model providers such as OpenAI and Anthropic are never allowed to train on your data.
Do I need consent to record with Granola?
Granola leaves it to you: its security FAQ makes you responsible for getting participants’ consent before recording. Because no bot joins the call, nothing announces the recording for you, so the disclosure is on you.
The on-device alternative
This trade-off used to be acceptable because local transcription used to be bad. That is no longer true. Apple Silicon runs Whisper large-v3, the same class of model cloud services use, on your Mac at cloud-grade accuracy (how on-device Whisper transcription works on a Mac).
Quietly takes that approach: bot-free capture like Granola, with the transcription and the AI cleanup pass running on-device. The audio never leaves your Mac, there is no account and no cloud store, and Quietly writes notes as plain Markdown to a folder you choose. For the NDA, legal, and hiring category above, that property is what makes the tool usable at all.
We keep a side-by-side of the two approaches in Quietly vs Granola, and a deeper explainer on what “local” means in private meeting transcription for Mac.
Trust Granola with the meetings you would be comfortable seeing in a vendor’s cloud. For the ones you wouldn’t, keep the audio on your Mac.
