# Privacy Policy for Twitter UP Helper

**Effective Date:** 2026-01-28

## Introduction

Twitter UP Helper ("we", "our", or "us") is a Chrome browser extension designed to assist users in generating and managing replies on the Twitter/X platform. We prioritize your privacy and are committed to protecting your data.

## Data Collection and Usage

### 1. Local Data Storage

We store the following data locally on your device using Chrome's `storage.local` API:

- **API Keys**: Your OpenRouter API key.

- **Settings**: Your preferences for the extension (e.g., language, templates).

- **History**: A local log of replies generated by the extension (stored only on your device).

- **Templates**: Custom reply templates you create.

**This data never leaves your browser and is not sent to our servers.**

### 2. AI Reply Generation (Third-Party Service)

To function, this extension interacts with **OpenRouter.ai**, a third-party AI service provider.

- When you use the "Generate AI Reply" feature, the text of the tweet you are replying to and your selected prompt settings are sent to OpenRouter's API.

- We do not control OpenRouter's data processing. Please refer to [OpenRouter's Privacy Policy](https://openrouter.ai/privacy) for details on how they handle data.

- We do not collect, store, or share this data on our own servers.

### 3. Twitter/X Interaction

The extension interacts with the Twitter/X website (`x.com` / `twitter.com`) solely to:

- Read the text of the tweet you selected to generate a context-aware reply.

- Insert the generated text into the reply input box.

- We do not scrape, track, or sell your browsing history or personal social media data.

## Data Sharing

We do not sell, trade, or transfer your personally identifiable information to outside parties. Data is only shared with OpenRouter.ai as explicitly initiated by your action (clicking "Generate Reply") for the sole purpose of generating the response.

## Your Consent

By using our extension, you consent to our privacy policy.

## Changes to our Privacy Policy

If we decide to change our privacy policy, we will post those changes on this page.
