Privacy

We don’t have a backend.

This site is a Next.js app served as static + lightly-rendered pages. There is no API server. There is no database that holds your data. We don’t have an analytics provider. We don’t track you across sites.

What’s stored, where it lives.

When you use this site, three things may save data in your browser (localStorage):

• Bookmarks — which mini-apps you starred
• Hiragana Master progress — your mastery state per kana
• Consent acknowledgment — so the welcome modal shows once

This data never gets sent anywhere. If you clear your browser data, it’s gone — we can’t recover it because we never had it.

Cookies.

We don’t set any cookies.

Third-party requests.

The site loads from Vercel’s CDN (or Boss’s own VPS as fallback). Fonts are self-hosted (Inter and Noto Serif JP) — no Google Fonts CDN call. The only third-party thing your browser will contact is GitHub if you click a link to the source repo.

Indonesian / international users.

We don’t collect personal information from anonymous visitors, so Indonesia’s UU PDP and Europe’s GDPR aren’t materially in scope. If we ever change that, this page will say so first.

Contact.

Boss is on github @syahiidkamil. Open an issue if anything here is unclear.
