Website TechStack Detector ("the Extension") is a Chrome browser extension designed to detect and analyze the technologies used by websites. We respect your privacy and are committed to keeping the Extension transparent and privacy-friendly.
Website TechStack Detector does not collect, sell, or transmit personal information.
The Extension does not collect:
Names
Email addresses
Passwords or authentication credentials
Financial or payment information
Health information
Precise location information
Browsing history
Personal communications
Keystrokes or mouse activity
User account information
The Extension does not require you to create an account or provide personal information to use its core functionality.
To identify technologies used by a website, the Extension may temporarily inspect information available to the active webpage, including:
HTML/DOM elements
Script and stylesheet URLs
Meta tags
Cookies or cookie-related information when technically required for detection
HTTP response headers
Publicly accessible page resources
Technology-specific indicators present in the webpage
This information is used only to identify technologies and generate the technology-stack report requested by the user.
The Extension does not use this information to build a browsing history, create user profiles, or track users across websites.
Information accessed by the Extension is used solely for its single purpose:
To detect and display the technologies used by the website the user chooses to analyze.
For example, the Extension may identify technologies such as React, Vue.js, WordPress, Shopify, Cloudflare, Google Analytics, Node.js, PHP, or other publicly detectable technologies.
Website TechStack Detector is designed to process detection information locally within your browser.
The Extension does not intentionally transmit website analysis results, website content, or user information to an external server.
No remote account, analytics service, advertising network, or external database is required for the Extension's core functionality.
The Extension may request permissions including:
The activeTab permission allows the Extension to access the currently active webpage after the user explicitly activates the Extension.
The scripting permission allows the Extension to execute its detection logic on the webpage selected by the user. This is required to inspect webpage elements and resources used for technology detection.
The storage permission may be used to temporarily store information required during the current technology-detection process, such as captured technical information used to identify backend technologies.
Stored information is not used to create user profiles or browsing histories and is not intentionally transmitted outside the user's browser.
The webRequest permission allows the Extension to inspect relevant HTTP response information, such as server-related response headers, when required to identify backend technologies and infrastructure.
The Extension does not use this permission to block, modify, redirect, or monitor requests for advertising or user tracking purposes.
Host permissions allow the Extension to analyze websites that the user chooses to inspect.
The Extension does not intentionally use these permissions to monitor a user's browsing activity or continuously track visited websites.
Website TechStack Detector does not sell, rent, or transfer user data to third parties.
The Extension does not intentionally send collected website-analysis information or personal information to third-party servers.
The Extension does not maintain a server-side database containing information about users or websites they analyze.
Any temporary technical information stored locally by the Extension is used only for the Extension's functionality and may be cleared when it is no longer required.
Website TechStack Detector does not use advertising trackers, user profiling systems, or third-party analytics services to track users of the Extension.
The Extension does not intentionally collect browsing history or create a record of the websites analyzed by the user.
The Extension does not knowingly collect personal information from children or require users to provide personal information.
We take reasonable measures to keep the Extension privacy-focused and minimize unnecessary access to user information.
Because the Extension operates within the browser and interacts with webpages selected by the user, users should understand that webpages themselves may contain third-party content, scripts, cookies, or other technologies outside the Extension's control.
This Privacy Policy may be updated when the Extension's functionality, permissions, or data practices change.
Any updated version will be published at the same privacy-policy URL, and the "Last Updated" date will be changed accordingly.
If you have questions, concerns, or requests regarding this Privacy Policy or Website TechStack Detector, you can contact the developer through the contact information provided on the Chrome Web Store listing.
