Privacy Policy
Last updated: 8 September 2026 · Applies to the ln-reader apps for
Android (com.vibetuned.ln_reader) and iPhone / iPad — published on the
App Store as L&N Reader (com.vibetuned.lnreader)
Short version: ln-reader collects nothing about you. There are no accounts, no analytics, no ads, and no tracking — on any platform. Everything you import and every position you save stays on your device.
1. Who we are
ln-reader ("the app") is developed by vibetuned ("we", "us"). It is an
offline audiobook player for .m4b files, available for Android and for
iPhone / iPad. This policy covers both apps and explains what they do and do not do
with your information.
2. Data we collect
None. The app does not collect, transmit, sell, or share any personal data. We operate no servers and have no accounts, sign-in, or user profiles. We cannot see your library, your listening activity, or anything else about how you use the app.
3. Data the app stores on your device
To work as an audiobook player, the app stores the following locally on your device only, inside its own private storage:
- Imported audiobooks — the
.m4bfiles (and optional EPUB and sync-manifest companions) you add, plus extracted metadata such as title, author, chapters, cover, and embedded images. - Reading positions and library state — your current position per book and your list of imported books, kept in the app's local database.
- Settings — preferences such as your chosen download location, playback speed, reader appearance, and sleep-timer options.
This data never leaves your device. Uninstalling the app removes it (see Device backups below).
4. Permissions and why we use them
On Android:
- Internet — used only to copy an audiobook from a cloud source you explicitly choose (e.g. Google Drive, OneDrive) into local storage during import. The app makes no other network connections and sends no data to us or any third party.
- Foreground service / media playback — lets playback continue in the background with controls in the system media notification and lock screen.
- Post notifications — shows the media-playback notification and sleep-timer notifications.
- Wake lock — keeps the device awake enough to continue playing audio while the screen is off.
On iPhone / iPad:
- Background audio — the standard iOS background-audio mode lets playback continue with the screen off, with controls on the lock screen and in Control Center.
- Notifications (optional) — asked for once, only to show the sleep-timer "expired" notification with its Postpone / Dismiss actions. The app works fully if you decline.
- Motion — the accelerometer is read only while a sleep-timer notification is pending, to support shake-to-postpone. Motion data is used in the moment and never stored or transmitted.
- The iOS app makes no network connections at all; cloud files you pick arrive through Apple's Files app and its providers.
5. File access
On Android the app uses the Storage Access Framework (SAF); on iPhone / iPad it uses the system document picker (the Files app). Either way, you pick the files you want to import and the app only accesses what you explicitly select — it copies your selection into its own private storage and never scans or browses your files on its own.
6. Third parties
The apps contain no advertising, analytics, crash-reporting, or tracking SDKs. When you import a file from a cloud provider (such as Google Drive, OneDrive, or iCloud Drive), that transfer is handled by your platform (Android's SAF or Apple's Files app) and the provider you chose, under their own privacy policies. We are not involved in and do not receive anything from that transfer beyond the file you selected.
7. Device backups
The apps allow the platforms' standard backups. On Android, Auto Backup may back the app's data up to your own Google account; on iPhone / iPad, the app's data may be included in your own iCloud or computer backups. These are functions of your device and your Google / Apple account, governed by their privacy policies — not something we operate or can access.
8. Children's privacy
The app is a general-purpose audiobook player and is not directed at children. Because it collects no personal data from anyone, it collects none from children.
9. Changes to this policy
If the app's behavior changes in a way that affects this policy, we will update this page and revise the "Last updated" date above.
