Tivra Privacy Policy
Last updated: May 25, 2026
Tivra is an audiobook app that turns your own PDFs and EPUBs into spoken audio entirely on your device. This page explains exactly what data Tivra touches, where it goes, and what it doesn't do.
TL;DR
- •We don't collect anything about you.
- •We don't have servers that store your data.
- •Your books, audio, translations, bookmarks, and reading progress live on your devices and (if you choose) in your private iCloud container.
- •We don't show ads. We don't share data with advertisers. We don't sell anything to data brokers because we don't have anything to sell.
What data Tivra works with
| Data | Where it lives | Who can see it |
|---|---|---|
| Your PDFs / EPUBs | On your device. Optionally synced via your private iCloud Drive container. | Only you and devices signed into your iCloud account. |
| Rendered audio (.m4a) | Same as above. | Same as above. |
| Translated text | Same as above. | Same as above. |
| Bookmarks and reading progress | Same as above. | Same as above. |
| Settings (preferred narrator, render-paused state, etc.) | Standard iOS UserDefaults on each device. | Only you. |
We never see any of this. Tivra has no backend service that receives, stores, or analyzes your reading material.

- ✕Your name, email, phone number, address, or any other identifying information
- ✕Account credentials (Tivra has no accounts to create)

- ✕Photos, contacts, calendar, microphone, or any sensor data

- ✕Crash reports beyond what you optionally share with Apple via the standard iOS / macOS crash-reporting prompt
- ✕Advertising identifiers
- ✕Any kind of cross-app or cross-website tracking
Third-party services Tivra uses
Tivra uses these services only for the purposes listed. None of them receive any data about you or what you're reading.
iCloud Drive (Apple)
Purpose
Optional sync of your library across your own Apple devices. Disabled by default if you're not signed into iCloud.
What gets sent
Your book files, encrypted in transit and at rest by Apple. Apple's standard iCloud terms apply.
iCloud Keychain (Apple)
Purpose
Synchronizes the encryption key for your audio files across your own devices.
What gets sent
A symmetric encryption key. Never leaves your iCloud account.
HuggingFace
Purpose
First-time download of optional on-device AI models (Kokoro, Gemma). You explicitly trigger this from Settings.
What gets sent
The model files you request. No personal information; just a model name.
Apple Translation framework
Purpose
On-device translation between languages. Runs locally.
What gets sent
Text from your book to Apple's on-device translation model. Apple states this stays on-device for translations.
WatchConnectivity (Apple)
Purpose
Sends playback state and (optionally) audio files between your iPhone and Apple Watch.
What gets sent
Book metadata and audio. Peer-to-peer only; never reaches our servers because we don't have any.
Data Tivra processes locally
To do its job, Tivra reads:
- •PDFs and EPUBs you explicitly import via the file picker or the share sheet
- •Audio output devices (so it can detect AirPods and route audio correctly)
- •File system timestamps on your library directory (used to detect when another device is rendering a book, so two devices don't duplicate work)
- •File sizes on disk (used to show storage usage in Settings → Storage)
- •System memory and processor info (used at launch to warn you if your device is under-spec'd for AI features)
All of this runs in the app's own process. None of it is transmitted anywhere.
How we handle your books
Books you import are stored in Tivra's own folder, either locally or in your private iCloud container. The folder layout is:
Audiobook/<book-id>/ book.json # title, author, language preferences chunks.json # text broken into narration units audio/*.m4a # rendered audio cover.jpg # extracted cover image source.pdf|.epub # a copy of the original you imported
These files are visible to you in the Files app under "iCloud Drive → Tivra" if you enable iCloud sync. You can delete them at any time — uninstalling Tivra also removes them from local storage (iCloud copies follow your normal iCloud-Drive deletion rules).
Subscriptions and payments
If you subscribe to Tivra Pro, the subscription is handled entirely through Apple's StoreKit. We don't receive your name, email, billing address, or payment method. Apple gives us only the subscription receipt — a token confirming that you're a current subscriber. Apple's privacy policy governs the payment data.
Children
Tivra is rated 4+ on the App Store. It contains no advertising, no in-app communication, no user-generated content discovery, and no tracking. It is safe for children to use under parental guidance, but it is not designed specifically as a children's app.
Your choices
Disable iCloud sync
System Settings → [Your name] → iCloud → iCloud Drive → toggle Tivra off. Your books then live only on the current device.
Delete your library
Long-press a book in Tivra → Delete. The book and all its audio go away.
Stop sharing crash reports with Apple
System Settings → Privacy & Security → Analytics & Improvements → toggle Share with App Developers off.
Changes to this policy
If we change anything material about how Tivra handles data, we'll update this page and the "Last updated" date at the top. Significant changes will also be surfaced in the app's next release notes.
