Privacy Policy

Who we are

Nyora is an independent, open-source project maintained by Md Hasan Raza. It is a manga reader — it does not host any manga content of its own. For anything privacy-related, you can reach us at hasanraza96@outlook.com.

Data stored on your device

By default, everything Nyora knows about you stays local — on the device you're reading on. That includes your library, favourites, custom categories, reading history and progress, bookmarks, reader settings and app preferences.

None of this is transmitted anywhere unless you turn on cloud sync. Uninstalling the app or clearing its data removes it from the device.

Optional cloud sync (Google Sign-In)

Cloud sync is off by default. If you choose to enable it, you sign in with Google Sign-In, which authenticates you. We receive a sign-in token and your basic Google account identifier (your email / account ID) for the single purpose of identifying your sync account.

We do not access your Gmail, contacts, files or any other Google data.

When sync is on, the data you've added — manga metadata, favourites, categories, reading history and progress, bookmarks and reader preferences — is stored in our backend on Supabase and tied to your account, so it follows you across your devices. It is used only to provide sync. It is never sold, and never used for advertising or profiling.

You can sign out at any time to stop syncing, and you can request deletion of your synced data whenever you like.

Content sources

Nyora is a reader, not a content host. It fetches catalogues, pages and images directly from the third-party manga websites — the sources — that you choose. Those sites receive your requests, including your IP address, and operate under their own privacy policies. Nyora is not affiliated with them and has no control over how they handle your data.

Translation

Text recognition (OCR) runs on your device using the operating system's own capabilities — for example Windows OCR, Apple Vision or other on-device models. Page images are never uploaded for OCR.

The recognized text is then sent to a third-party machine-translation service — Google Translate — to produce the translation. Only the extracted text is sent: not the image, and not your account information. If you optionally configure your own AI provider key (bring-your-own-key), the text is sent to that provider instead, under their terms.

Trackers

Trackers are optional. If you connect AniList, MyAnimeList, Shikimori or Kitsu, Nyora shares your reading progress for the relevant titles with that service — with your authorization, and subject to that service's own privacy policy.

What we don't do

• No advertising and no advertising IDs.
• No analytics, telemetry, usage tracking or crash-reporting SDKs.
• No selling or renting of personal data.
• No account required just to read.

Third parties your data may reach

Depending on which features you enable, data may reach:

• Google — sign-in and translation.
• Supabase — storage for synced data.
• The manga source websites you browse.
• Any tracking service you link.
• Any AI translation provider whose key you supply.

Each of these is independently responsible for what it processes.

Data retention & deletion

Local data persists until you delete it or uninstall the app. Synced data is retained for as long as your sync account exists. Deletions propagate via a soft-delete marker, so your other devices learn that an item has been removed.

To delete your synced account and data, sign out and / or email hasanraza96@outlook.com.

Security

Nyora uses HTTPS wherever the source or service supports it. Authentication and synced storage are handled through Supabase's managed authentication and database security. No method of transmission or storage is perfectly secure, so we limit collection to the minimum that each feature requires.

Children

Nyora is a general-purpose reader and is not directed at children. Because it can access third-party sources that may contain mature content, it is intended for users who are old enough under their local law and the relevant store's age rating.

International transfers

Enabling networked features may process data on servers located in other countries — for example, wherever Supabase or Google operate. By using those features, you consent to such transfers.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the effective date and reposting the policy at its public URL.
