Privacy Policy
Last Updated: January 26, 2026
1. Introduction
Welcome to TikTok Underdog Radar ("we," "our," or "us"). We are committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our Chrome Extension (the "Extension").
By installing and using the Extension, you agree to the collection and use of information in accordance with this policy.
2. Information We Collect
A. Personal Information
We do not collect, store, or transmit any personally identifiable information (PII) such as your name, address, phone number, or email address. You do not need to create an account to use the basic features of this Extension.
B. Usage Data & Content
To function correctly, the Extension may interact with the content of the web pages you visit (specifically tiktok.com).
- • Page Content: The Extension analyzes the HTML of the TikTok page you are viewing to identify data points (such as follower counts or engagement metrics). This analysis happens locally on your device. We do not send this browsing history to external servers.
-
•
Local Storage: We may use Chrome's local storage API (
chrome.storage) to save your user preferences or settings (e.g., custom filters). This data remains on your browser and is not synchronized with us.
3. How We Use Your Information
We use the information accessed by the Extension solely for the following purposes:
- • To provide functionality: To analyze TikTok profiles and display the "Underdog" metrics as requested by you.
- • To improve user experience: To remember your settings so you don't have to re-configure the Extension every time.
We do not sell, trade, or rent your personal identification information to others.
4. Permissions
To function, this Extension requires certain permissions from your browser:
- • "Read and change your data on tiktok.com": This permission is strictly used to analyze the visible public data on TikTok pages to generate the radar reports. We do not access your private messages, passwords, or cookies for other sites.
- • Storage: Used to save your local configurations.
5. Third-Party Services
We do not use third-party analytics services (like Google Analytics) inside the extension to track your browsing behavior.
6. Data Security
The security of your data is important to us. Since the Extension processes data locally on your device, your data is protected by the security measures of your own browser and computer. We do not maintain a central database of user data.
7. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes.
