Privacy Policy

Last updated: May 03, 2026

This Privacy Policy describes how your personal information is handled when you use the Private Notes mobile application (the "App"). Because Private Notes is built for absolute privacy, our core principle is that your data stays on your device.

1. INFORMATION WE DO NOT COLLECT

To provide a truly private experience, we have fundamentally designed the App to avoid collecting your data:

  • We do not collect, store, or transmit your notes.

  • We do not collect, store, or transmit your AI chat history.

  • We do not collect, store, or transmit your voice recordings or generated speech.

  • We do not require an account, email address, or registration to use the App.

2. HOW YOUR DATA IS PROCESSED LOCALLY

All core functionality of the App happens exclusively on your Android device:

2.1 Notes and Semantic Search

Your notes and the embeddings generated for semantic search are stored securely in your device's local database. They are never uploaded to a cloud server.

2.2 Local AI Chat

When you interact with your notes using the AI assistant, the App uses on-device LLMs (such as Gemma models). Your prompts and notes are processed locally by your device's hardware.

2.3 Voice Features

The App uses your device's built-in speech-to-text and text-to-speech capabilities. Audio data is processed in real-time on your device and is immediately discarded. It is never transmitted to us or third-party cloud AI providers.

3. INFORMATION WE MAY COLLECT

The only information that may be collected is standard, anonymized operational data required to maintain the App:

3.1 Usage and Device Information

If you opt-in to standard Android crash reporting, we may receive anonymized data including:

  • Device type and model

  • Operating system version

  • Anonymous crash logs and error reports

This data contains no personal information, notes, or chat history. It is used exclusively to debug technical issues and improve App stability.

4. THIRD-PARTY SERVICES

Unlike traditional AI applications, Private Notes does not send your chats or voice inputs to third-party AI providers like OpenAI, Anthropic, or Google Cloud.

The App may utilize standard Google Play Services (such as billing for Pro subscriptions), which are governed by Google's Privacy Policy.

5. DATA SHARING

Because we do not collect or host your personal data, notes, or chat history, we have no personal data to sell, rent, trade, or share with third parties, AI providers, or law enforcement.

6. DATA RETENTION AND DELETION

You are in complete control of your data retention.

  • Your notes, embeddings, and chat history remain on your device until you choose to delete them within the App.

  • If you uninstall the App, all associated local data and databases are permanently deleted by the Android operating system.

7. DATA SECURITY

While we do not transmit your data over the internet, we rely on Android's native application sandboxing to protect your local database from unauthorized access by other applications on your device. We recommend securing your device with a strong passcode or biometric authentication to further protect your physical device.

8. CHILDREN'S PRIVACY

The App is not intended for use by children under the age of 13. Because the App operates entirely offline and requires no account, we have no mechanism to knowingly collect personal information from any user, including children under 13.

9. YOUR RIGHTS

Depending on your location (such as under the GDPR or CCPA), you have rights regarding your personal data. Because all your personal data resides exclusively on your physical device and not on our servers, you can exercise your rights to access, correct, or delete your data directly within the App's interface without needing to submit a request to us.

10. CHANGES TO THIS PRIVACY POLICY

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. We will notify you of any material changes by updating the "Last updated" date on this page.
