Privacy Policy
Last Updated: 2026-03-06
This policy explains what data Alt processes across the website, desktop app, and iOS app, when external transfer can occur, and what controls users have. This policy applies equally to all platforms (web, desktop, and iOS).
At A Glance
- This policy applies equally to the website, desktop app, and iOS app.
- Speech recognition (STT) is processed locally via the on-device Whisper model.
- Summarization, chat, AI scribe, translation, and title generation support LocalLLM or API modes.
- With LocalLLM or when API mode is not selected, no data is transmitted externally and the app can operate fully offline.
- Before using API mode, the app displays a consent prompt detailing the data recipient, data transmitted, and purpose. Data is only transmitted after you explicitly consent.
- With API mode, which requires your explicit consent, transcript text and memo content may be sent to third-party AI providers (OpenAI, Anthropic, Google) to provide the requested AI features. The audio recording files themselves are not transmitted to these third-party AI providers for external AI features.
- Our server acts solely as a relay тАФ it does not store transmitted data or retain any logs.
- The website processes account, billing, download, feedback, and analytics data.
- Analytics tools include Google Analytics (GA4), PostHog, and Vercel Analytics.
1. Scope and Definitions
This policy applies equally to all platforms listed below.
- Desktop App: Alt application running on macOS and Windows
- iOS App: Alt application running on iPhone and iPad
- Website: altalt.io features including account, billing, download, and sharing
- LocalLLM Mode: AI processing handled on-device
- API Mode: AI processing handled through our servers and integrated API providers
2. App (Desktop and iOS) Data Processing
The following applies equally to both the desktop app and iOS app.
2.1 Always Local Processing
- Speech recognition (STT) runs locally using the on-device Whisper model.
- Recordings, transcripts, and generated outputs are primarily stored on your device.
2.2 Optional AI Processing (LocalLLM/API)
- AI features include summarization, chat, AI scribe, translation, and note title generation.
- LocalLLM: Processing remains local and can be fully offline. When using LocalLLM mode or when API mode is not selected, no data is transmitted externally.
- API: Only when you choose to use API-based AI features and complete the necessary consent process, transcript text and memo content may be transmitted to OpenAI, Anthropic, and Google to perform your requested features such as summarization, translation, AI scribe, note title generation, and chat. The audio recording files themselves are not transmitted to these third-party AI providers.
2.3 Prior Consent Process
- Before using API mode, the app displays an in-app consent prompt that clearly states: (1) what data is transmitted (transcript text and memo content), (2) who receives it (OpenAI, Anthropic, Google), and (3) for what purpose (performing the AI feature you requested, such as summarization, translation, or title generation).
- Data transmission begins only after you explicitly consent through the in-app prompt.
- You may disable API mode at any time to stop data transmission.
2.4 Server Processing and Retention
- Our server acts solely as a relay тАФ it forwards your request to the third-party AI service provider and returns the response.
- User input data (transcript text, memo content) is not stored long-term on our servers and is discarded once the request is processed. However, minimal technical logs may be temporarily generated for service operation, security, and troubleshooting. We ensure these logs do not contain the full content of your AI feature inputs.
- Each AI service provider maintains equivalent levels of data protection consistent with industry standards.
