1. Introduction

Welcome to Nanote ("we," "our," or "us"). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we handle your information when you use our mobile application (the "App").

2. Data Collection and Usage

2.1. User Content

The App allows you to upload study materials (PDFs, images, notes) to generate quizzes.

• Processing: When you generate a quiz or use AI features, your uploaded content is sent to OpenAI’s GPT API for processing.
• Storage: We do not store your study materials or generated quizzes on our own servers. All your data is stored locally on your device.
• AI Processing: By using the App, you acknowledge that your content is processed by OpenAI’s models to provide the service.

2.2. Personal Information

We do not collect personal identifiers (such as your name, email address, or phone number) directly.

• Authentication: If you use "Sign in with Apple," your authentication is handled by Apple. We only receive an anonymous unique identifier to associate your local data with your account on this device.

2.3. Usage & Purchase Data

We may collect anonymous, aggregated usage data to improve App stability.

• Transactions: We use RevenueCat to manage subscriptions and in-app purchases. This service handles anonymous purchase records to valid pro access locally. We do not store or process your credit card information directly.

3. Data Security

Since your data is stored locally on your device, the security of your data relies largely on your device's security settings. We recommend keeping your device updated and secured with a passcode or biometrics.

4. Third-Party Services

The App processes data using the following third-party processors:

• OpenAI API: For generating quizzes, grading, and summarizing content.
