Lexory Privacy Policy
Effective date: November 1, 2026
Lexory is a book and audiobook reader for iPhone and iPad. We (the developer of Lexory) do not collect your data. The one exception is information about purchasing the app itself: it is verified by the RevenueCat service (see "Purchasing the app" below).
What Lexory does not have
- No ads, analytics, counters or third-party tracking libraries.
- No Lexory account: no sign-in is required.
- No data sent to the developer. We have no server of our own that the app sends anything to; the developer never receives your books, notes or words.
Purchasing the app
Lexory is free to download, the first 7 days are a free trial, and then the app is bought once, for life, with no subscription. The trial and the purchase are App Store purchases: Apple takes the payment, and neither Lexory nor RevenueCat receives your payment details. Purchases are verified by RevenueCat (RevenueCat, Inc.). When the app checks purchases (at launch and when you return to the app), and when you start the trial, buy the app or restore purchases, RevenueCat receives your App Store purchase records (product, date, price and storefront country), a random anonymous customer ID created in the app, and the iOS and app versions. Your name, email address, books and other data are not sent to RevenueCat. This information is not linked to your identity and is not used for advertising or tracking; in RevenueCat the developer sees only purchases and their statistics. RevenueCat processes it under its own privacy policy: revenuecat.com/privacy.
Where your data is stored
Books, audiobooks, reading positions, bookmarks, highlights, notes, words and settings are stored on your device. If iCloud sync is on (on by default, can be turned off in More ▸ Sync), this data is stored in your private iCloud database, and book files are stored in your iCloud Drive if "Store books in iCloud" is on. Only you have access to them; storage is provided by Apple under its privacy policy. Backups are created in the app's folder on the device.
Keys for network services and WebDAV passwords are stored in the iOS Keychain on the device and are sent only to the service they belong to.
When the app uses the network
Only to services you choose, and only while you use them:
| Service | When | What is sent |
|---|---|---|
| iCloud (Apple) | Sync or storing books in iCloud is on | Reading and listening positions, bookmarks, highlights, words, collections, settings; book and audiobook files |
| RevenueCat (purchasing the app) | Checking purchases at launch and when you return to the app; the trial, a purchase, restoring purchases | App Store purchase records, an anonymous customer ID, the iOS and app versions |
| Cloud text-to-speech: OpenAI, Yandex SpeechKit | A cloud voice is selected and you have given consent | The text of the passage being read aloud, the chosen voice; your key (OpenAI, Yandex) |
| Network translation: DeepL, Google Cloud Translation, Yandex Translate | A network translator is selected, your key is set and you have given consent | The selected text and the sentence around it, languages; your key |
| WebDAV | You open your server | Requests for folder listings and files, your user name and password — only to that server |
| Download by link | You enter a link | A request for the file at that link |
| Wi-Fi transfer | The Wi-Fi Transfer screen is open | Nothing goes to the internet: a computer on your local network sends books to the device |
| Offline voices (GitHub) | You download a voice in the Speech sheet | A request for the voice model file; no book text is sent |
Before book text is first sent to cloud speech or network translation, the app asks for your consent. Consent can be withdrawn in More ▸ Privacy, in the Speech sheet and in More ▸ Translation & Dictionary; after that, speech and translation work on the device only. These services process the data they receive under their own privacy policies (OpenAI, Yandex, DeepL, Google).
The vocabulary review reminder is a notification from the device itself: nothing is sent over the network. CarPlay shows audiobooks on the car screen through the device connection, without the internet.
There are no other connections. Pictures, styles and fonts that a book links to on the internet are not loaded — only what is in the book file is shown. Language packs for Apple Translation are downloaded by the system. A web link in a book opens in Safari, and only when you tap it: the page is loaded by Safari, and Lexory doesn't see what you do there. "Search the Web" opens Safari too.
Children
Lexory does not collect personal data, including children's data; RevenueCat receives only purchase information, as described above.
Deleting data
Deleting the app deletes all data on the device. Data in iCloud can be deleted in Settings ▸ [your name] ▸ iCloud ▸ Manage Storage ▸ Lexory. To delete purchase information held by RevenueCat, write to the address below.

Changes to this policy are announced on this page. Questions: lexory@ava3v.com.
This website
This website sets no cookies and runs no analytics or third-party scripts. It remembers whether you chose iPhone, iPad or Mac screenshots in your browser's local storage; that choice stays in your browser and is never sent anywhere. The hosting provider (Spaceship) keeps standard server logs (IP address, time, requested address, browser) for security and operation of the service; see the hosting provider's retention policy. When you tap an App Store link, Apple receives the campaign parameters of the link.
