Privacy Policy for X Account Labeler

Effective Date: March 3, 2026  |  Last Updated: March 24, 2026

Yuki Eliot ("I", "me", or "my") developed the X Account Labeler browser extension (the "Extension"). This Privacy Policy explains how your information is collected, used, and protected when you use the Extension.

1. Information Collection and Use

The Extension processes two categories of data:

a) Local label data (never leaves your device)
The custom labels you create — X/Twitter usernames and your chosen colors — are saved directly to your browser using the chrome.storage.local API. This data is stored entirely on your device and is never sent to any server or third party.

b) Anonymous install and uninstall events
When you install or uninstall the Extension, an anonymous randomly generated ID (UUID) is created and stored locally on your device. This ID is sent to my server (yukieliot.com) solely to record the install or uninstall event for analytics purposes.

This ID:

• Is randomly generated and contains no personal information
• Cannot be used to identify you personally
• Is not linked to your Google account, X account, browser history, or any other data
• Is used only to count installs and uninstalls to understand how the Extension is being used

No browsing history, post content, messages, or any other personal data is ever collected or transmitted.

2. Required Permissions and Justifications

• Storage: Used to save your customized account labels and the anonymous install ID locally on your device.
• Host Permissions (*://*.x.com/*, *://*.twitter.com/*): Used to identify usernames on your X/Twitter timeline so the Extension can apply your saved color labels. The Extension does not read, log, or transmit post content, messages, or browsing history.
• Host Permissions (https://yukieliot.com/*): Used exclusively to send anonymous install and uninstall events to my own server for analytics purposes.

3. Third-Party Data Sharing

I do not share, sell, rent, or trade any user data with third parties. The anonymous install/uninstall events are logged only on my own server and are not shared with anyone.

4. Data Retention

Anonymous install and uninstall event logs are retained for analytics purposes and may be deleted periodically. You can request deletion of your anonymous ID's records by contacting me.

5. Changes to This Privacy Policy

I may update this Privacy Policy from time to time to reflect changes in the Extension's features or legal requirements. Any updates will be posted on this page with a revised Last Updated date.
