Privacy Policy

1. Overview

TextBetter ("we", "our", or "us") is a premium AI writing assistant Chrome extension designed to help you write better directly inside your browser. We value your privacy above all else. This Privacy Policy outlines what information is used, how it is stored, and who receives it.

2. Data Collection and Transmission

TextBetter operates under a strict serverless and local-first architecture:

• No Personal Data Collection: We do not collect, request, or store your name, email address, password, browsing history, or payment information.
• No Writing Logs: Text you highlight or submit for AI correction is processed immediately and is never logged, saved, or cataloged by our extension.
• No Third-Party Analytics: The extension does not load third-party analytics trackers, cookies, or telemetry software.

3. Third-Party Services (Google Gemini API)

To perform writing improvements, TextBetter interfaces directly with the Google Gemini API:

• Direct Request Flow: All requests for writing corrections are transmitted directly from your local browser client to Google's official Gemini API endpoints (https://generativelanguage.googleapis.com).
• No Intermediaries: No intermediary servers, databases, or proxy services receive your text or API keys.
• Google's Privacy Terms: Since requests are sent directly to Google AI Studio, their usage is governed by the Google API Client Terms and Google Privacy Policy. You can learn more about how Google processes API data at Google's developers documentation site.

4. Chrome Extension Permissions Explained

To function correctly, the extension requests the following permissions from your browser:

• storage: Used to save settings locally (your API key, model preference, active styling options, and custom prompts) in the browser's sandbox via chrome.storage.local.
• Host Permission (https://generativelanguage.googleapis.com/*): Required to send network requests directly from the extension to Google's Gemini API servers.
• Content Script Matches (<all_urls>): Necessary to display the overlay icon/menu next to highlighted text on the web pages you actively read and write on. Your page content is read solely for the purpose of selecting the highlighted text and injecting the inline writing assistant UI.

5. Key and Configuration Storage

Your Gemini API key is stored securely in your browser's local sandbox storage using chrome.storage.local. It is never transmitted anywhere other than Google's secure API endpoint. For maximum security, we recommend that you generate a dedicated API key with restricted limits in your Google AI Studio dashboard.

6. Changes to this Policy

We may update our Privacy Policy from time to time. Any changes will be posted directly to this page and will take effect immediately upon updating.
