LuceVoce privacy policy
Last updated: 13 November 2026. Applies to LuceVoce for Windows, Mac, iPhone and iPad.
The short version
LuceVoce has no account, no server of its own, no advertising and no analytics. Your books, notes, highlights, settings and voice notes stay on your devices. LuceVoce reads aloud on the device itself: the voices, the speech recognition of voice notes and voice commands, and translation all run on your computer, phone or tablet.
LuceVoce goes on the internet only for the things listed below, and only when you use them.
What LuceVoce sends, to whom, and when
| When you... | LuceVoce contacts | What it sends |
|---|---|---|
| download a voice, a speech model for voice notes, or a language for translation | GitHub (github.com and its file servers), where LuceVoce's own model files are kept | a request for the file; GitHub sees your IP address, as any website does |
| open Free books (at most once a week) | Project Gutenberg | a request for its public catalogue file, so Free books can search it on your device |
| open Free books, search it or download a book | the source you use: Project Gutenberg, LibriVox and the Internet Archive, Wikisource and WS Export, unglue.it, the Open Textbook Library, or a catalogue you added yourself | your search words, the book you download, and LuceVoce's name and version |
| turn on "Look up book information online" (off at first) | the sources you leave on: Open Library, Wikidata, the National Library of France (BnF), CrossRef | a book's title, its first author, and its ISBN or DOI; nothing else about the book or about you |
| turn on Wiktionary in the dictionary settings (off at first) and look up a word | Wiktionary (Wikimedia) | the one word you look up |
| add a web page by its address, or from the clipboard | that website | a request for that page |
| use Search the web or More books | nothing from LuceVoce: your web browser opens with the search filled in, under your browser's own policy | |
| turn on sync | nothing from LuceVoce: it writes small files to the folder you chose (iCloud Drive, OneDrive, Dropbox, Google Drive or another folder), and your cloud provider copies them under its own policy | |
| buy the unlock | the Microsoft Store or the Apple App Store, which handle the payment under their own policies; LuceVoce never sees your payment details |
Each request carries your device's IP address, as any internet request does. LuceVoce adds no identifier of you or of your device.
The microphone
Voice notes and voice commands use the microphone only while you record a note or give a command. The words are recognised on the device (Windows: the speech model you downloaded; Mac, iPhone and iPad: Apple's speech recognition on the device). LuceVoce keeps only the words of a voice note, never the recording, and keeps nothing of a voice command.
What stays on your device
Your library and the books you add, your reading places, notes, highlights, bookmarks and voice notes' words, your settings, the voices and models you downloaded, and LuceVoce's own log files (used only to find problems; they are never sent anywhere). Uninstalling LuceVoce, or removing its data folder, removes them. The Microsoft Store edition also keeps how many minutes of the free hour were used, in Windows' Credential Manager, so that an uninstall does not reset it; it holds a number and nothing else.
The parts of your system LuceVoce uses
On Windows LuceVoce shows its pages with Microsoft Edge WebView2, and on Apple devices with Apple's WebKit. These components follow your system's own privacy settings, including any diagnostic data your system sends to Microsoft or Apple. LuceVoce does not turn any of them on.
Children
LuceVoce collects nothing from anyone, children included.
Your rights
Because LuceVoce keeps no personal information about you anywhere but on your own devices, there is nothing for us to give you, correct or delete: you can see, export and delete everything in the app itself. If you have a question about this policy, write to the person in charge of personal information below.
If you write to us
An email you send for help is kept only as long as it takes to answer it and to follow up on it, then deleted; it is never shared or used for anything else.

Changes
If LuceVoce ever sends anything more, this page will say so before the version that does it is released, and the date above will change.
What sync writes to your folder
Sync is off until you turn it on and pick a folder you already use: iCloud Drive, OneDrive, Dropbox, Google Drive or Box. LuceVoce then writes small files into that folder and your cloud service copies them to your other devices. LuceVoce has no server and never sees these files. They hold your devices' names, each book's title, author and a fingerprint of the file, your reading places with a few words of text around them, your highlights, notes, bookmarks, tags, ratings and reading status, the theme, speed and voices you chose, and copies of books, audiobooks and voices only if you choose to share them. Please keep that folder private. Your cloud provider's own privacy terms apply to it.
