StackMate — Privacy Policy

Effective date: April 25, 2026
Extension: StackMate — Tech Stack Scout

This privacy policy describes what data StackMate collects, what it does not collect, and how the extension behaves on your device. It is written in plain language so any user can understand it.

TL;DR (summary)

StackMate runs locally in your browser. It does not collect personal information, browsing history, IP addresses, cookies, form data, passwords, or any content that can identify you. When you click the StackMate icon, the extension scans the page you are currently viewing to detect well-known third-party tools (such as CRM, email marketing, or hosting providers) and displays alternative recommendations. No part of that scan is sent to any server.

What StackMate does

  1. When you click the toolbar icon, StackMate reads a small set of public technical signals from the active page — typically the page’s HTML, <meta> tags, and the URLs of <script> tags that the page itself has already loaded.
  2. It compares those signals against a list of well-known software products (the detection rules) bundled with the extension.
  3. It shows you the matched products in the pop-up and—if available—recommends an alternative product. Recommendations include affiliate links that may pay a small referral fee to the developer if you sign up.

What StackMate does NOT do

  • It does not read or store the contents of forms, passwords, or any data you type.
  • It does not record your browsing history.
  • It does not identify you. There is no account, no login, no email collection.
  • It does not track you across sites.
  • It does not sell or share any data, because no data is collected.
  • It does not modify pages you visit, inject ads, or replace any other party’s affiliate cookies.

Data leaving your browser

StackMate only makes outbound network requests in two situations:

  1. Refreshing the recommendation list. Periodically (about once every six hours), the extension fetches an updated copy of the recommendation list from a public URL controlled by the developer. This request transmits no information about you, your browsing activity, or the pages you visit. It is identical to your browser opening that public file.
  2. When you intentionally click an affiliate “Get deal” button. The button opens the partner site in a new tab, exactly like any normal hyperlink. The partner site (for example, Hostinger or Pipedrive) may then drop its own affiliate cookie according to its own privacy policy. StackMate does not read or modify that cookie.

If we ever add anonymous, aggregate counters in the future (for example, “tool X was detected N times this week”), they will be opt-in, free of personal data, and disclosed in this policy with the date of change.

Permissions explained

  • activeTab and required so that, when you click the StackMate icon, it can read the public technical signals of the page you are looking at. The scan only runs when you click — never automatically.
  • storage Stores the cached recommendation list locally in your browser so the pop-up opens instantly.
  • alarms schedules the periodic background refresh of the recommendation list.

Children

StackMate is not directed to children under 13. It does not knowingly collect data from any user.

Changes to this policy

If we change anything in how StackMate handles data, we will update the date at the top of this document and post the change in the extension’s listing.
