Introduction
Welcome to Smart Note AI! We are committed to protecting your privacy and ensuring the
security of your personal information. This Privacy Policy explains how we, Smart Note AI (operated by
Hoàng Nhật Long), collect, use, and protect your information when you use our intelligent note-taking
application.
Smart Note AI helps you transform your notes into summaries, mind maps, quizzes, and flashcards using AI
technology. We also provide text-to-speech capabilities, voice recording for note creation, and
AI-powered chat assistance.
1. Information We Collect
a. Information You Provide Directly
- Account Information: When you create an account, we collect basic information such
as your email address, name, and profile picture through Firebase Authentication.
- Note Content: We collect and store the notes, text, files, and voice recordings you
create within the app. This content is stored securely in Firebase Storage and is only accessible to
you.
- Voice Recordings: When you use the voice recording feature to create notes, we
temporarily process your audio to convert it to text. The original audio may be stored with your
note if you choose to keep it.
b. Information Collected Automatically
- Device Information: We collect basic device information including device type,
operating system version, device identifier, and app version to provide our services and send push
notifications.
- Usage Analytics: We collect information about how you use the app, including
features accessed, number of notes created, and time spent in the app. This is collected through
Firebase Analytics.
- Crash Reports: We automatically collect crash and error reports through Firebase
Crashlytics to improve app stability and fix bugs.
- App Configuration: We use Firebase Remote Config to deliver app updates and feature
toggles.

2. How We Use Your Information
We use the information we collect for the following purposes:

generate AI-powered summaries, mind maps, quizzes, and flashcards, and provide text-to-speech
functionality.

generate summaries and other AI-powered features. This data is processed in real-time and is not
used to train AI models.
