Benkyō

Overview

Benkyō is a personal Japanese study app. This policy explains what data is collected and how it is used. Benkyō is designed to be privacy-friendly — most data never leaves your device.

Data Stored Locally

The following data is stored exclusively in your browser's localStorage and is never transmitted to any server:

SRS (spaced repetition) progress per card
Daily review counts and accuracy
Study streak data
App settings (e.g., daily goal)

This data remains on your device and is cleared if you clear your browser storage.

Account Data (Optional)

If you sign in with Google, Benkyō stores your name, email address, and profile image to identify your account. This data is used solely to associate your study progress with your account and is not sold or shared with third parties.

Analytics

Benkyō uses Vercel Analytics to collect anonymous, aggregated page-view data (e.g., which pages are visited). No personal information is included in these analytics events.
