Is Cloud Dictation Safe? What You Need to Know
Cloud dictation sends your voice to servers. Here's what actually happens to that audio, which services store it, and how to make an informed choice.
Every dictation tool makes a choice about where your voice gets processed. Some do it on your device. Most send it to a server. Tap2Talk sends your audio to Groq’s cloud API for transcription. That is a fact worth understanding, not hiding from.
Cloud dictation privacy is the question you should be asking before you install any speech-to-text tool. The answer depends less on whether audio leaves your machine and more on what happens to it once it does.
How Cloud Dictation Actually Works
When you hold your hotkey in Tap2Talk and speak, here is the chain of events:
- Your microphone records audio locally
- That audio is sent to Groq’s Whisper API over an encrypted connection
- Groq’s servers transcribe the audio to text
- The text is returned to your machine
- The text is sent to Groq’s LLM for cleanup (grammar, punctuation, formatting)
- The cleaned text is pasted wherever your cursor is
Steps 2 through 5 involve your data leaving your device. That is the reality of cloud-based dictation, and it applies to Tap2Talk just as it does to Google Voice Typing, Otter.ai, or macOS Dictation in its default mode.
The question is not whether your audio leaves your device. It does. The question is what the provider does with it afterward.
What Happens to Your Audio at Groq
Groq processes audio through their Whisper API. Under their API terms of service, audio submitted through the API is processed and discarded. It is not stored for model training. It is not retained in a database. It is not used to build voice profiles.
This is meaningfully different from consumer-facing voice services where the business model involves collecting data. Groq’s business model is selling API compute, not harvesting training data. Your audio is the input to a function call, not a product.
That said, there is always a window during processing where your audio exists on their infrastructure. For the few seconds it takes to transcribe, your voice data is on Groq’s servers. After that, it is gone.
How Other Services Handle Your Voice
Not every dictation service works the same way. Here is how the major players handle privacy.
Apple Dictation
Apple processes dictation on-device for newer Macs with Apple Silicon. Older Macs and some features still use cloud processing. When on-device, nothing leaves your machine. Apple has been moving toward local processing and deserves credit for that. The limitation is that Apple’s on-device model is less accurate than cloud alternatives, and the dictation interface is clunky for power users.
Windows Voice Typing
Microsoft’s built-in dictation sends audio to Microsoft’s cloud servers. Their privacy statement notes that voice data may be used to improve speech services unless you opt out. The opt-out is buried in Windows settings under Diagnostics and Feedback. Most users never change it.
Dragon NaturallySpeaking
Dragon processes everything locally. No audio leaves your machine. This is the gold standard for dictation privacy and has been for decades. The trade-off is a $699 price tag, Windows-only support, and software that has not seen meaningful updates in years. Nuance (now owned by Microsoft) has shifted focus to enterprise healthcare products.
Google Voice Typing
Google retains voice data by default. You can delete it manually through your Google account activity settings, but the default is storage. Google uses this data to improve their speech recognition models. If you use Google Docs dictation, your voice data is part of the training pipeline unless you actively opt out.
Otter.ai
Otter stores your audio and transcripts on their servers as a feature, not a side effect. Your recordings are accessible in your Otter account. This is useful for meeting notes but means your voice data lives on a third-party server indefinitely.
A Comparison Table
| Service | Audio leaves device | Stored after processing | Used for training | User control |
|---|---|---|---|---|
| Tap2Talk (via Groq) | Yes | No | No | You own the API key |
| Apple Dictation (Apple Silicon) | No | N/A | N/A | On by default |
| Windows Voice Typing | Yes | Depends on settings | Opt-out available | Buried in settings |
| Dragon | No | N/A | N/A | Fully local |
| Google Voice Typing | Yes | Yes (default) | Yes (default) | Manual deletion |
| Otter.ai | Yes | Yes (feature) | Yes | Account settings |
The API Key Model Changes the Dynamic
One thing that makes Tap2Talk different from most cloud dictation tools: you bring your own Groq API key. You sign up at console.groq.com and generate a key. Your audio goes directly from your machine to Groq under your account.
Tap2Talk never sees your audio. It never touches our servers. There is no Tap2Talk server sitting between you and Groq. The app on your machine talks directly to Groq’s API using your credentials.
This means your privacy relationship is between you and Groq, governed by Groq’s API terms. Tap2Talk is the interface. Groq is the processor. You are the account holder.
When Cloud Dictation Is Fine
For most people and most use cases, cloud dictation with a reputable provider is perfectly acceptable. Drafting emails, writing blog posts, taking personal notes, composing messages — the privacy risk is minimal.
The audio exists on a server for seconds. It is processed and discarded. The provider has no economic incentive to store or misuse it. The connection is encrypted. This is comparable to the privacy trade-off you make every time you use a search engine or send a message through any cloud service.
When You Should Think Twice
If you regularly dictate content that includes other people’s sensitive information — medical records, legal case details, financial data, therapy notes — cloud dictation of any kind introduces risk. Not because the provider is malicious, but because the data passes through infrastructure you do not control.
For these use cases, fully local dictation tools like Dragon (if you can stomach the price and Windows-only limitation) or running Whisper locally on your own hardware are better fits. Tap2Talk is not a local processing tool. It is honest about that.
The Bottom Line
Tap2Talk uses cloud processing. Your audio goes to Groq. Groq processes it and discards it. No storage, no training, no retention. You control the API key and the direct relationship with Groq.
Is that safe enough? For general productivity work, absolutely. For dictating classified or regulated information, you should evaluate whether any cloud service meets your compliance requirements.
The best thing you can do is understand exactly what happens to your data — and now you do.
Frequently Asked Questions
Does Tap2Talk store any of my audio or transcripts?
No. Tap2Talk does not operate any servers that handle your voice data. Audio goes directly from your machine to Groq’s API using your personal API key. After Groq processes the transcription, the audio is discarded per their API terms. Tap2Talk never sees, stores, or has access to your recordings.
Is Groq’s Whisper API more private than using OpenAI’s Whisper API?
Both process audio server-side. The key difference is in their data policies. Groq’s API terms state that data is not used for model training. OpenAI’s API data policy also states API data is not used for training by default (as of March 2023), but OpenAI has a longer history of changing policies. Read the current terms of whichever provider you use.
Should I avoid cloud dictation entirely if I care about privacy?
Not necessarily. The question is what you are dictating and what level of risk you accept. Cloud dictation with a process-and-discard provider like Groq is fundamentally different from a service that stores and trains on your data. For everyday writing and productivity, the risk is negligible. For regulated data (medical, legal, financial), consult your compliance requirements.
