Privacy Policy
Last updated: May 5, 2026
1. Overview
LynxNote ("the app") is an iOS application developed by Engin Şahin. This privacy policy explains the app's data collection, usage, and storage practices.
🔒 Core principle: LynxNote never sends or stores any user data on its own servers. All your data resides only on your device.
2. Data We Collect
LynxNote collects and stores the following data on your device only:
- Audio recordings (m4a format, stored in device storage)
- Transcription text
- AI-generated summaries and research content
- Action items and notes
- App preferences (language selection, model preference)
This data is never sent to LynxNote servers because LynxNote has no servers or backend infrastructure whatsoever.
3. Third-Party API Services
LynxNote connects to the following third-party services via the user's own API keys:
OpenAI Whisper API
Audio files are sent to OpenAI for transcription. The user uses their own API key and is subject to OpenAI's privacy policy. openai.com/privacy
Anthropic Claude API
Transcription text is sent to Anthropic for summarisation and research. The user uses their own API key and is subject to Anthropic's privacy policy. anthropic.com/privacy
Groq API (optional)
If the user selects Groq as their transcription or AI provider, data is sent to Groq and subject to Groq's privacy policy. groq.com/privacy-policy
Note: Data sent to these APIs is used solely for the operations requested by the user. LynxNote does not mediate this communication — it goes directly from the user's device to the API provider.
4. Microphone & Speech Recognition
The app requires microphone permission to record audio. For offline transcription, Apple's built-in speech recognition service is used. This data is subject to Apple's privacy policy.
5. API Key Security
API keys entered by the user (OpenAI, Anthropic, Groq) are stored encrypted in iOS Keychain. These keys are never sent to LynxNote servers, logged, or shared with any third party.
6. Data Retention & Deletion
All app data is stored on your device. You can delete data at any time from within the app. Uninstalling the app permanently deletes all data from your device.
7. Children's Privacy
LynxNote is designed for users aged 17 and above. We do not knowingly collect data from individuals under the age of 13.
8. Changes
We may update this policy from time to time. For significant changes, a notification will be provided within the app. You can always access the current policy on this page.
