Bookaholic — Privacy Policy

Last updated: 2026-07-14 · 繁體中文

Bookaholic ("the app") is a language-learning e-book reader with a dictionary-lookup vocabulary notebook and spaced-repetition review. This policy explains what the app does — and does not do — with your information.

Short version

Bookaholic does not collect or sell any personal data. There are no accounts, no analytics, no advertising, and no third-party tracking SDKs. Everything you create in the app stays on your device. Bookaholic works fully offline — no word or reading data is ever sent to any dictionary service or web search. The only network activity is optional and user-initiated: downloading an Apple Translation language pack the first time you translate into a new language (managed by iOS; translation itself happens on your device), and downloading an optional offline dictionary file from the app's own release assets.

Data stored on your device only

The following are stored locally on your device and are never uploaded to us or anyone else:

• Books and documents you import (EPUB, TXT, PDF, Markdown)
• Reading progress, bookmarks, and highlights
• Your vocabulary notebook, saved words, and the sentences they came from
• Review history and spaced-repetition schedule
• Collections, tags, and all app settings

This data is included only in an encrypted device backup if you choose to make one through Apple's iTunes/Finder or iCloud device backup. Bookaholic itself does not run any cloud sync in this version.

Deleting your data

Because everything lives on your device, deletion is entirely in your hands:

• One book: use the book's ⋯ menu → Delete. This removes the book's files, reading progress, bookmarks and highlights. Words you saved from it that appear in no other book are removed together with their review history.
• Individual words, highlights or notes: delete them in place from the Vocabulary or Notes tab.
• Everything: deleting the app from your device deletes all of its data. There is no copy on any server, so there is nothing further to request or erase — and no account to close.

Optional network features

Bookaholic works fully offline by default. Its built-in dictionaries (JMdict, Japanese WordNet, KANJIDIC2, CC-CEDICT and other open data) are bundled in the app, and you can optionally download additional offline dictionary files from the app's own release assets — this fetches a file and sends no personal data. The only other optional network feature is described below.

Apple Translation

Bookaholic also offers an optional Translate feature, built on Apple's on-device Translation framework, and a Chinese-gloss fill-in for saved words that uses the same framework.

When you translate a passage or a saved word's gloss is filled in, the text involved is passed to Apple's Translation framework so it can be translated on your device. The first time a given language pair is used, iOS may need to download that language's Apple translation data over the network. Apple performs this translation and manages these downloads; it is governed by Apple's own privacy policy, not this one. You can turn the machine-translation fill-in off in Settings → Languages & Translation.

Data we collect: none

• We do not collect analytics or usage statistics.

• We do not have access to your library, vocabulary, or reading activity.

Children's privacy

Bookaholic does not collect personal information from anyone, including children.
