Karatu
Privacy Policy
This Privacy Policy explains how Karatu, developed by Dexino Cloud & AI Solutions, handles information when you use the application.
1. Documents and files
Karatu allows users to open or import supported reading content such as PDF and EPUB documents and associated media.
Documents selected by the user are used only to provide the requested reading or playback functionality.
Under the current local-first design, documents are not intentionally uploaded to Dexino servers as part of normal reading functionality.
2. File access
Karatu may request access to files or media selected by the user. Access is used to open, display, organise or play the selected content.
Karatu does not use file permissions to search for unrelated personal documents.
3. Reading and playback progress
The application may store information locally such as reading position, audiobook playback position, recently opened material and application preferences.
This allows users to continue from where they previously stopped.
4. Audio and Android Auto
Karatu may use Android media playback services to support audiobook playback, background audio, automatic progression between tracks and compatible vehicle interfaces such as Android Auto.
Playback may temporarily pause or reduce volume in response to navigation instructions, calls or other system audio events.
5. Text-to-speech
Where text-to-speech functionality is available, text from a document may be processed by the selected speech engine for the purpose of reading content aloud.
The privacy behaviour of an external or operating-system text-to-speech engine may be governed by the provider of that service.
6. Accounts and personal information
Karatu does not require users to create a Dexino account to use its core local reading features.
Dexino does not use the app to directly collect users' names, contact lists, personal messages or complete copies of their documents as part of normal local reading functionality.
7. Third-party services
Karatu may use Google Play and Android platform services for distribution, security, updates, billing or compatible media functionality.
Google's privacy policy is available at Google Privacy Policy .
8. Data sharing
Dexino does not sell users' personal information, documents or reading history.
Files are not intentionally shared with third parties by Dexino unless a user explicitly invokes a sharing feature or an external service is required for a feature selected by the user.
9. Data security
Users remain responsible for protecting access to their device and the documents stored on it.
Dexino uses reasonable technical measures intended to minimise unnecessary collection or transfer of users' reading material.
10. Changes to this Privacy Policy
This policy may be updated if Karatu later introduces cloud synchronisation, accounts, advertising, online text processing or other functionality that changes its data practices.
