FAQ ​

Is this another Tachiyomi fork? ​

No — and that's the point. Otaku Reader is a from-scratch app (100% Kotlin, Jetpack Compose, clean architecture) that deliberately implements the Tachiyomi extension API, so it runs the same community extensions as Tachiyomi, Mihon, and Komikku without forking a decade of legacy code. Same ecosystem, new foundation.

Where does the content come from? ​

From sources you install. The app ships with no sources and hosts no content.

There are two kinds, side by side in the same list: community-maintained APK extensions (the Tachiyomi/Mihon ecosystem — this is where the great majority of sources are) and JavaScript sources from the Mangayomi ecosystem, which need no APK install and run in a sandboxed process. Both come from repositories you add — see Extensions & Repositories.

Does it phone home? ​

No. There are no analytics, no ads, no AI features, and no account system. The only network calls the app makes on its own are the ones you configure: library updates from your sources, tracker sync you've logged into, extension repo refreshes, and update checks against GitHub. Crash reporting exists but is opt-in and only works with a Sentry endpoint you supply.

My repo URLs from Komikku — do they work? ​

Yes, unchanged. Same index.min.json format, same extensions. The app also asks each repo for a JavaScript index; a repo that doesn't serve one is perfectly normal and isn't treated as an error.

Why does the app ask me to "trust" an extension? ​

Extensions are executable code. The first time you install one from a new signing certificate, the app shows the signer's hash and asks once. This is a security feature, not friction for its own sake — see the trust model.

Can I read my own files? ​

Yes — the local source reads CBZ/ZIP/EPUB from a folder you choose, and OPDS support connects to self-hosted servers like Komga and Kavita.

Is my reading hidden from prying eyes? ​

If you want it to be: biometric/PIN app lock, secure screen (blocks screenshots and recents thumbnails in the reader), incognito mode (no history, no tracker updates), and locked categories.

What Android versions are supported? ​

Android 8.0 (API 26) and up.

Where do I report a bug or request a feature? ​
