-Plain-English summary (not legally binding — the terms below govern):
-
-  - You CAN use Stroke for free — personally, in your company, in schools,

-    including the Pro features.
-  - You CANNOT sell Stroke, charge money for it, rebrand it as your own

-  - Pro features are key-gated in official builds. The source is public so you
-    can audit and contribute to it, but removing or bypassing the license-key

+Copyright (c) 2026 Nischal Dahal
+
+You may do whatever you want with the Stroke source code and other source
+files (from here on referred to as the "Stroke Source"), with the following
+restrictions:
+
+- If you publish any work derived from the Stroke Source, you must make it
+  apparent in some way that it is derived from Stroke.
+- If you have created an executable program (from here on called "Your
+  Program") compiled from some source code and/or other source files (from
+  here on called "Your Source"), and if Your Source includes files or source
+  code copied or derived from the Stroke Source, then you may only publish
+  Your Program under the following conditions:
+	- Your Program does not contain any malware or hidden malicious content.
+	- You may not charge users money for Your Program, and Your Source must
+	  contain the monetization systems present in the Stroke Source,
+	  including the license-key activation, trial period tracking, and
+	  payment system, without any alterations. All of these systems must be
+	  active and working as intended in Your Program, and payments made
+	  through them must go to the original author of Stroke. That is unless
+	  Your Source features substantial improvements or additions to the
+	  Stroke Source, such that Your Source should be considered its own,
+	  derivative work, separate from the Stroke Source. Removing, bypassing,
+	  or replacing the monetization systems, renaming or restyling the app,
+	  or other cosmetic changes do not by themselves count as substantial
+	  improvements or additions.
+	- Your Program is not published under the name "Stroke", or under a name
+	  or icon so similar to Stroke's that users could mistake Your Program
+	  for Stroke.

+OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,

+# Notes on the Stroke License
+
+The Stroke License is based on the MMF License, which Noah Nuebling wrote for
+Mac Mouse Fix (https://github.com/noah-nuebling/mac-mouse-fix/blob/master/License).
+The MMF License is itself based on the MIT and DBAD licenses.
+
+I wrote it with two goals in mind:
+
+1. To stop people from publishing apps built from Stroke that contain malware,
+   or that look just like Stroke except that when you buy a license, someone
+   other than me gets paid.
+2. To let everyone else do anything they like with the Stroke source code.
+   That includes reusing it in their own free and paid projects, publishing
+   bug fixes and improvements to Stroke, and building something substantially
+   better on top of Stroke and charging for it.
+
+There are no restrictions on how you use the source code. You can read it,
+change it, build it, and run it yourself. The restrictions only apply to
+publishing apps compiled from it.
+
+Stroke is source-available, not open source. The Open Source Definition from
+the Open Source Initiative does not allow conditions like the ones above, so
+this is not an OSI-approved open source license.
+
+Stroke is a paid app with a free trial. Buying Stroke Pro at
+https://stroke.click buys a license key for the Stroke app. It does not change
+these terms, and you do not need one to use the source code.
+
