Privacy Policy
Effective date: March 13, 2026
Overview
DetectZeStack provides a technology detection API and a free Chrome extension. We are committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.
Chrome Extension
The DetectZeStack Chrome extension reads only the URL of your current tab when you click the extension icon. This URL is sent to the DetectZeStack API to detect the website's technology stack.
- No personal data is collected, stored, or transmitted.
- We do not track your browsing history, keystrokes, or form inputs.
- We do not read or modify any page content.
- Results are cached locally in your browser for one hour to reduce API calls.
- Your data is not sold, shared, or transferred to third parties.
- The extension only activates when you click it — it does not run in the background.
API Service
When you use the DetectZeStack API (directly or through the extension), we receive the domain name you submit for analysis. We log:
- The domain analyzed
- Your IP address (for rate limiting only; not stored long-term)
- Timestamp of the request
We do not collect names, email addresses, or any personally identifiable information through the API.
Website Analytics
The DetectZeStack website uses Google Analytics 4 to understand traffic patterns. This is standard web analytics and does not apply to the Chrome extension or API.
Data Retention
Technology detection results are cached on our servers to improve response times. IP addresses used for rate limiting are not stored beyond the current session.
Changes to This Policy
We may update this policy from time to time. Changes will be posted on this page with an updated effective date.
