Privacy & Security
Your voice is yours. LotusQ is built from the ground up so your audio never has to leave your device. And when it does, you're in control.
0 Bytes to the Cloud by Default
On the free tier, all transcription happens locally using the Whisper engine running on your own device. Your voice data never touches our servers, any third-party server, or the internet. Zero.
Local Whisper Engine
LotusQ bundles the Whisper speech recognition model directly into the app. It runs entirely on your CPU or GPU. No internet connection is required for transcription on the free tier.
Zero Audio Storage
We never store audio recordings, not on your device, not on our servers. Audio is processed in real-time and the buffer is immediately purged from memory once transcription is complete.
Tauri-Powered, No Hidden Network Calls
LotusQ is built on Tauri (Rust + native webview). Unlike Electron-based apps, it has no bundled Chromium and makes no background network calls you haven't opted into. What you see is what runs.
TLS 1.3 Encryption in Transit
When you opt into cloud features (Pro tier), all audio is transmitted over TLS 1.3 encrypted channels to our processing partners. Data is never stored by LotusQ after transcription is returned.
Built for Regulated Industries
Lawyers, healthcare professionals, and financial advisors trust LotusQ because the free tier processes everything locally. No compliance review needed when audio never leaves your machine.

Detailed Privacy Policy
1. Information We Collect
We collect the minimum necessary to run the service: your email address (for authentication), subscription status, and anonymous crash/error logs for debugging. We do not collect your dictation content, audio recordings, or usage patterns. Your personal dictionary and snippets are stored locally on your device (free tier) or encrypted in our cloud database (Pro tier, opt-in).
2. Audio Data & Transcription
Free tier: All audio is processed locally by the Whisper engine running on your device. No audio is transmitted anywhere. Pro tier: Audio is streamed over TLS 1.3 to our cloud ASR partners solely for the purpose of transcription. Audio is processed in real-time and is not retained by LotusQ or our processing partners after transcription is returned. We do not use your audio to train any models.
3. Auto-Learn Dictionary
LotusQ monitors text fields 7 seconds after dictation to detect corrections you make. This comparison happens entirely on your device. The field text is read via OS accessibility APIs (UI Automation on Windows, AXUIElement on macOS) locally. Corrections are saved to a local file on your device. When synced to the cloud (Pro tier), dictionary entries are encrypted in transit and at rest.
4. Data Retention
Account data is retained for as long as your account is active. Audio buffers are destroyed immediately upon transcription completion, no exceptions. Correction history and dictionary entries are stored locally and only synced to our cloud database if you are a Pro user and have enabled sync. You may request full account deletion at any time by emailing [email protected]. We will purge all associated data within 7 days.
5. Third-Party Services
We use a small number of carefully selected third-party services to run LotusQ. Our authentication and cloud database provider stores account credentials and encrypted dictionary/snippet data for Pro users. Our payment processor handles all billing. LotusQ never sees or stores your payment card details. Pro tier cloud transcription is handled by reputable ASR providers under strict data processing agreements; audio is sent solely for transcription and is not retained or used for training.
6. Your Rights
You have the right to access, correct, or delete any personal data we hold. You can export your dictionary and snippets at any time from the app. To request account deletion or a data export, contact [email protected]. We will respond within 7 days.
7. Children's Privacy
LotusQ is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us immediately.
