Traductor is a one-developer app. The fastest way to get help is to email hardyharsh82@gmail.com — please include:

If the issue involves a specific book, mentioning the file format (EPUB or PDF) and roughly where in the book it occurred helps a lot.

Frequently asked

Do I need an account?

No. Traductor has no sign-in, no account system, and no cloud sync. Everything lives on your iPhone.

Where is my data stored?

Locally on your device. Your imported books, your personal dictionary, your reading positions, and your settings are all in the app’s local storage. They are not backed up to any server we control. If you want a backup, use iCloud Backup or iTunes/Finder backup of your iPhone.

How do I reset the app?

Because there is no settings-reset surface in v1, the way to fully reset Traductor is:

  1. Delete the app from your Home Screen (long-press → Remove App → Delete App).
  2. Reinstall from the App Store.

This removes all imported books, all saved dictionary entries, and all preferences. It is not reversible, so consider exporting anything important first.

How do I import a book?

EPUB and text-based PDF files can be imported from:

Image-based (“scanned”) PDFs without a text layer cannot be tapped for translations.

Why doesn’t translation work?

Translation runs on-device via Apple’s Translation framework. The first time you use a new language pair, iOS will download a language pack — this needs an internet connection. Once the pack is on your device, translation works offline.

If you see the offline indicator (wifi.slash) in the lookup popover, translation succeeded using your downloaded language pack and the external dictionary buttons are skipped because they need the internet.

Which languages are supported?

Reader-side: English, French, German, Spanish, Italian, Portuguese, Dutch, Russian, Polish, Ukrainian, and Hindi. The translation target is whatever languages Apple’s Translation framework supports for your source language.
