EchoNote Privacy Policy

Effective Date: February 11, 2026

1. Overview

EchoNote ("the App") is an audio recording and AI-powered transcription app for Android. Your privacy is important to us. This policy explains what data the App accesses, how it is used, and your choices.

2. Data We Collect

Microphone Audio – The App records audio using your device microphone when you explicitly press the Record button. Audio files are stored locally on your device in app-specific storage.
Google Account Information – When you sign in with Google, we receive your email address and display name solely for authentication. We do not access your contacts, calendar, or other Google data.
Usage Counter – We track the total number of seconds of audio you have transcribed using the free tier. This counter is stored as an anonymised key-value pair (hashed user ID → seconds) in Cloudflare KV.

3. How Audio Data Is Processed

When you request a transcription or summary, the audio is sent to one of the following third-party AI services:

Groq (groq.com)
Google Gemini (ai.google.dev)
OpenAI (openai.com)
Speechmatics (speechmatics.com)

Audio is transmitted in-memory for processing and is not permanently stored on our servers or the third-party services beyond the duration of the API request. Please refer to each provider's own privacy policy for their data handling practices.

4. BYOK (Bring Your Own Key)

If you choose to use your own API keys, those keys are stored on your device using encrypted local storage. In proxy mode, selected BYOK keys may be transmitted to our proxy in request headers for key validation and provider API calls. If you enable "Direct Mode," requests are sent directly from your device to the AI provider without passing through our proxy.

5. Data Sharing

We do not sell, rent, or share your personal data with any third parties for marketing or advertising purposes. Audio data is only transmitted to the AI service providers listed above for the sole purpose of transcription and summarisation.

6. Advertising & Analytics

The App does not contain any advertising SDKs or third-party analytics trackers.

7. Data Retention & Deletion

Audio recordings are stored locally and can be deleted at any time from inside the App. You may also delete your server-side usage record and all local data from Settings → Delete account data.

8. Children's Privacy

The App is not directed at children under 13. We do not knowingly collect personal information from children.

9. Changes to This Policy

We may update this policy from time to time. The updated version will be posted at this URL with a revised effective date.
