Privacy Policy

1. Introduction

Study Kit ("we", "us", "our") operates the website usestudykit.com and the web application at app.usestudykit.com. This Privacy Policy explains how we collect, use, and protect your information when you use our service.

2. Information We Collect

Account Information

When you create an account, we collect:

• Email address
• Full name
• Timezone (auto-detected from your browser)

You can sign in with email (one-time password) or Google OAuth.

Study Data

As you use Study Kit, we store:

• Study goals and lessons you create

• Vocabulary items (terms, definitions, pronunciation, example sentences)
• Spaced repetition review progress
• Study schedules

Usage Data

We track basic activity events (e.g., answering a question, completing a lesson) to compute performance metrics and personalize your experience. We do not use third-party analytics or advertising trackers.

Performance Analysis

We use AI to analyze your study performance and generate recommendations, including accuracy metrics, strengths, weaknesses, and suggested next steps. This analysis is stored with your account.

3. How We Use Your Information

We use your information to provide, personalize, and improve the Study Kit service — including generating study content, sending reminders, and securing your account.

These services process data only as necessary to operate Study Kit. We do not sell your data to any third party.

5. Data Storage & Security

Your data is encrypted in transit and at rest. All connections use HTTPS. We do not store passwords — authentication is handled via one-time codes and OAuth.
