Privacy Policy

Last Updated: August 14, 2026
🌱 Privacy Summary: LexiTab is 100% privacy-first. All your vocabulary words, definitions, and study progress are stored locally on your device. We do not collect, track, or sell your personal data.

📖 1. Introduction

At LexiTab, we take your privacy seriously. This policy describes how we handle your data when you install and use the LexiTab Chrome extension.

📖 2. Data Collection & Local Storage

LexiTab does not collect, store, or transmit any personal data to external servers. All vocabulary words, definitions, and learning progress are stored locally in your browser's IndexedDB. We do not have access to this data.

Your theme preference and reminder settings are stored using chrome.storage.sync, which is encrypted by Google and tied directly to your logged-in Chrome profile.

🔗 3. Third-Party APIs

When you save a word, the extension sends a request to the Free Dictionary API (api.dictionaryapi.dev) to fetch the English definition, phonetics, and audio.

To provide Vietnamese translations, we send requests to the MyMemory API (api.mymemory.translated.net). These services may log requests. We do not control their data handling. Please refer to their respective privacy policies.

🔒 4. Data Security

Because data never leaves the browser, there is no risk of data breaches on our servers.

🛡️ 5. User Rights & Data Control

You can delete all your data at any time via the 'Reset All Data' button in the extension dashboard, or by clearing your browser data.

📝 6. Changes to This Policy

We will update this page if the extension's functionality changes.
