Privacy Policy for Arabic Reader Browser Extension

1. Introduction

Welcome to Arabic Reader Extension (“we”, “our”, “us”). We are committed to protecting your privacy. This Privacy Policy explains how our Chrome browser extension (“Arabic Reader” or “the Extension”) handles your information.

2. Information We Do NOT Collect

Arabic Reader Extension is designed with privacy as a core principle:

No account registration required — You can use all features without creating an account.
No personal data collection — We do not collect, store, or transmit any personal information to external servers.
No analytics or tracking — We do not use any analytics SDKs or tracking tools.
No advertising — The extension contains no advertisements or ad-related tracking.
No browsing history recording — We do not record or transmit the URLs you visit.

Chrome Web Store Privacy Disclosure Summary

The following text summarizes the privacy information used for the Chrome Web Store privacy questionnaire.

Single purpose: Arabic Reader helps users read and learn Arabic on web pages and PDFs by adding Tashkeel vowel marks, dictionary lookup, root and I’rab hints, text-to-speech, translation, and a built-in PDF reader directly in the browser.

Storage permission justification: The storage permission is used only to save user preferences locally in the browser, such as enable/disable state, hover mode, definition language, speech rate, translation engine, target language, UI language, theme, and PDF detection settings. Arabic Reader does not use storage to collect personal data, browsing history, analytics, advertising identifiers, or tracking information.

Host permission justification: The extension needs host access so it can detect Arabic text on the pages the user visits, add Tashkeel annotations, show the hover dictionary, speak or translate selected text when requested, and open PDF URLs in the built-in reader when PDF Smart Detection is enabled. Page content is processed locally for annotation and dictionary lookup. Only text that the user explicitly selects and translates is sent to the selected third-party translation provider.

Remote code and analytics: Arabic Reader does not load remote code, does not use analytics SDKs, and does not include advertising or tracking.

3. Data Stored Locally in Your Browser

The Extension stores the following data locally in your browser only (via Chrome Storage API):

Data Type	Purpose	Storage
Extension settings	Preferences (enable/disable, hover mode, definition language, speech rate, translation engine, target language, PDF detection, etc.)	Browser local storage
UI language preference	Remember your chosen interface language	Browser local storage

Important: All data listed above exists only in your browser. It is never uploaded to any server. If you uninstall the extension, this data will be permanently deleted.

4. How Tashkeel Processing Works

All Tashkeel (Arabic vowel marks) annotation is performed entirely locally within your browser:

The Extension uses bundled Tashkeel dictionaries and NLP algorithms within the extension.
Arabic word recognition, root extraction, homograph disambiguation, and I’rab analysis happen on-device.
No text is sent to any external server for Tashkeel processing.

5. Dictionary Feature (Multilingual Definitions)

The Extension includes built-in local dictionaries for Arabic learning:

Tashkeel dictionary for Arabic vowel marks and learner-friendly vocalization.
English definitions from a bundled Wiktionary Arabic subset.
French definitions from a bundled Wiktionary Arabic subset.
Dictionary data is stored locally within the extension.
All dictionary lookups are performed entirely offline — no network requests are made.
The dictionary data is loaded on-demand and unloaded when disabled to conserve memory.

6. PDF Reader

The Extension includes a built-in PDF reader powered by PDF.js (Mozilla’s open-source PDF rendering library):

PDF files are rendered and processed entirely in your browser. No PDF content is sent to any external server.
When PDF Smart Detection is enabled, the extension uses Chrome’s declarativeNetRequest API to redirect .pdf URLs to the built-in reader. This redirect happens locally within your browser — no data leaves your device.
All Tashkeel annotation, dictionary lookup, and text-to-speech features within the PDF reader operate locally.

7. Translation Feature & Third-Party Services

The Extension includes an optional translation feature that sends selected text to third-party translation services for processing:

Service	Provider	Data Sent
Bing Translate	Microsoft Corporation	Selected text only
Google Translate	Google LLC	Selected text only

Important:

Translation is triggered only when you explicitly click the translate button or use the translate keyboard shortcut / context menu. Text is never sent automatically.
Only the selected text is transmitted — no URLs, browsing history, personal data, or other page content is sent.
The text is sent directly to the translation provider’s API. We do not relay, store, or log any translation requests or responses on our servers.
Please refer to Microsoft’s Privacy Statement and Google’s Privacy Policy for details on how these providers handle data.

8. Text-to-Speech

The Extension uses Chrome’s built-in TTS (Text-to-Speech) API:

Speech synthesis is handled by your browser’s built-in engine.
No audio data is recorded or transmitted.

9. Permissions Explained

The Extension requests the following browser permissions:

Permission	Purpose
`storage`	Store user settings (enable/disable state, hover mode, speech rate, translation preferences, PDF detection, etc.)
`tts`	Use Chrome’s built-in Text-to-Speech to read Arabic pronunciation
`scripting`	Execute scripts in web pages to add Tashkeel annotations
`contextMenus`	Add right-click menu options to speak and translate selected Arabic text, and to open PDF links in the built-in reader
`notifications`	Show a notification when a PDF page is detected, allowing quick access to the built-in PDF reader
`declarativeNetRequest`	Redirect PDF URLs to the built-in PDF reader for Tashkeel annotation (when PDF Smart Detection is enabled)
`declarativeNetRequestWithHostAccess`	Required for PDF redirect rules to work on any website
`<all_urls>`	Add Tashkeel annotations to Arabic words on any webpage; proxy translation requests to third-party APIs from the background service worker; intercept PDF URLs for the built-in reader

10. Third-Party Libraries

Library	Purpose	Data Handling
PDF.js (Mozilla)	Render PDF documents	Runs entirely locally
Wiktionary subsets	English/French definitions for Arabic words	Pre-built data bundled locally
Built-in Tashkeel dictionary	Arabic vowel marks and learner vocalization	Bundled locally and processed on-device

Open-source Dictionary Attribution

Arabic Reader bundles offline dictionary resources from open-source or public projects:

Arabic definition data: English and French definitions are derived from Wiktionary Arabic entries and packaged as local subsets for offline lookup.
Tashkeel data: the built-in Tashkeel dictionary is curated for Modern Standard Arabic, Classical Arabic orthography, and Arabic learners, with references to public Arabic vocalization resources such as Tashkeela-style corpora during dataset preparation.

All dictionary lookups run locally in your browser, and we do not operate a dictionary backend service.

Upstream projects retain their own copyright and license terms. For authoritative licensing details, please refer to each project’s official repository or website.

11. Children’s Privacy

The Extension does not knowingly collect personal information from children under 13 years of age. Since we do not collect any personal information from any users, the Extension is safe for users of all ages.

12. Data Deletion

To remove all Extension data:

Uninstalling the extension will permanently remove all associated settings from your browser.
You can also clear extension data via Chrome Settings > Extensions > Arabic Reader > Details > Clear Data.

13. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be reflected in the “Last updated” date at the top of this page.
