Privacy Policy

Summary

Chytach Manga is a fully client-side web application. No data you interact with ever leaves your device. There is no server, no account system, no analytics, and no network requests tied to your usage or content.

What we store and where

All data created by the application is stored exclusively in your browser using the Web Storage APIs:

• IndexedDB — your CBZ files (as Blob objects), cover thumbnails, and reading progress are stored locally in your browser's IndexedDB database named chytach-manga. This data never leaves your device.
• localStorage — a single key (chytach-help-v1) is written to remember whether you have already seen the welcome instructions.

We do not use cookies. We do not set any tracking identifiers. We do not transmit any of this data to any server.

Network requests

The only network requests the application makes are to load its own static assets (HTML, JavaScript, CSS, fonts, icons) from the server that hosts it. After the first load, these assets are cached by the service worker and the app runs entirely offline — no further network requests are made.

Your comic files and reading data are never uploaded or transmitted anywhere.

Service worker

Chytach Manga registers a service worker to enable offline use. The service worker caches only the application shell (static files). It does not cache, read, or transmit any of your comic files or reading data.

Third-party services

We do not integrate any third-party analytics, advertising, error-tracking, or telemetry services. No third party receives any information about your use of the application.

Fonts are loaded via next/font/google, which downloads font files at build time and serves them from the same origin as the application. No requests are made to Google Fonts at runtime.

Your control over stored data

Because all data is stored locally in your browser, you have full control over it:

• Remove individual books from within the app library.
• Clear all application data by clearing your browser's site data for this origin (Settings → Privacy → Site Data in most browsers).
• Uninstalling the PWA removes the installed app shell; clearing browser site data removes the stored books and progress.

Children's privacy

The application does not collect any personal information from anyone, including children. There is no age restriction on using the application itself; however, the content of CBZ files is the responsibility of the user.

Changes to this policy

If this policy is updated, the effective date at the top of this page will change. Because the application collects no data, material changes are unlikely.
